[SOLVED] Help needed to configure postfix

I aim to be able to manage myself my mailserver.
For now i just need help in order to configure postfix so i can send an email from my postfix configured mail to my gmail account.
I've read the following wiki pages :
https://wiki.archlinux.org/index.php/postfix
https://wiki.archlinux.org/index.php/Si … ail_System
Wich are really not informative.
I've my own domain name, wich can be pinged, i will call it : domain.free.fr
Here is what i've done so far :
Install postfix :
sudo pacman -S postfix
Configure myhostname in /etc/postfix/main.cf
myhostname = domain.free.fr
Configure the username in /etc/postfix/aliases
root: glow
Reload aliases and postfix
newaliases
postfix reload
postfix status
postfix/postfix-script: the Postfix mail system is running: PID: 11706
Then i've tried to use sendmail to send an email to my gmail adress :
sendmail [email protected]
Test
Nothing coming in my mail.
What do i do wrong ?
Ican't find any log about postfix, /var/log/mail.log do not exist, is this normal ?

Help needed in configuring AQJMS Adapters

hi
We are working on Soa 11g
we need help to configure the following,
1) configuration of JMS adapter from a BPEL service and
2) weblogic server side configuration
to consume JMS messages from RIB AQ RMS service.
The version details of the softwares used are as follows,
1) RIBAQ is 13.2
2) RMS 13.2
3) weblogic 10.3.2
4) Oracle soa 11.1.1.2
we have configured the following
1. a data source with jndi name 'jdbc/rmsjms'was created to connect to the RIBAQ database.
2. a jms module was created
3. a foreign server was created within the jms module
4. the foreign server had 'JNDI PRoperties'assigned to 'datasource=jdbc/rmsjms'and JNDI Initial Context Factory to 'oracle.jms.AQjmsInitialContextFactory'
5.the foreign server points to two foreign destination topics
4. the destinations had to be given a remote JNDI and Local JNDI names
5. a connection factory bearing reference to the JNDIname of JMS adapter viz.eis/aqjms/Topic was created.
kindly clarify on the following points.
1. what is expected to be the value and format of 'JNDI Properties' within the foreign server.
2.what is expected to be the value of remote JNDI and Local JNDI names of the remote destinations in the foreign server
3.which of these shd reflect in the adapter configuration in the bpel code.
TIA

1. what is expected to be the value and format of 'JNDI Properties' within the foreign server.In the JNDI Properties field, enter datasource=<datasource jndi location>. Replace the place holder with the JNDI location of your data source.
2.what is expected to be the value of remote JNDI and Local JNDI names of the remote destinations in the foreign server In the Local JNDI Name field, enter the local JNDI name you would use in your application/composite to look up this destination.
In the Remote JNDI Name field, enter Queues/<queue name>if the destination is a queue, or enter Topics/<topic name> if the destination is a topic.
3.which of these shd reflect in the adapter configuration in the bpel code.As mentioned above, use Local JNDI Name in adapter configuration in composite.
Please refer section "8.4.8 AQ JMS Text Message" at below link -

I've tried my best to go through the code, looking for typos and such, but I haven't had any luck and much of what happens I don't really understand.
So please, if you can, I'd very much appreciate a little help.
Best regards.
NB:
Some might conclude that this script does something illegal. In actuality that is not so, just make that clear. Also, testing from outside Denmark, will probably not be possible.

You know a lot more than we do: like where you then found this code, and what it is supposed to do.
My only first thought without looking through random code that allegedly serves some unknown purpose and comes from some unknown source is that the shebang is ambiguous: it may be a python 2 script while /usr/bin/python is now python 3.
I've pretty much concluded that python 3.3 is the right choice, sp that should not be a problem, as for what it does, it uses "rtmpdump" to record or "rip" video from a danish site "dr.dk", which is a public service television network.
I have it from reliable sources that this actually works, or at least did at some point, on Windows machines, but of course i'm on linux, and that complicated matters.
All in all, as I understand it, what the script really does, is retrieving the relevant rtmp link. The rest is up to "rmtpdump" which I should be able to manage.
In any case, I'm not really that concerned with learning what the script does at this point, but rather what the error mean.
The only actual error description I see is: "TypeError: 'NoneType' object is not iterable" and I haven't a clue what that implies. I've read through the script, but haven't been able to find any obvious flaws..

[Solved] help needed with wireless setup (ralink 2860 driver)

Hi,
I'm new to Arch so please be gentle ;-)
I recently upgraded hoping to find improved support for my wireless. I now find that the kernel recognises and loads the appropriate module:
[root@akoya ~]# uname -a
Linux akoya 2.6.29-ARCH #1 SMP PREEMPT Wed Apr 8 12:47:56 UTC 2009 i686 Pentium(R)
[root@akoya ~]# lspci | grep Net
05:00.0 Network controller: RaLink RT2860
[root@akoya ~]# lsmod | grep 2860
rt2860sta 514808 1
I checked over the kernel source and the rt2680sta module is the code from ralink cleaned up for the 2.6.29 kernel. (I tried building the ralink release but it needs patching for 2.6.29)
However getting the thing to connect using WPA is another thing altogether
[root@akoya ~]# ifconfig ra0 up
[root@akoya ~]# wpa_supplicant -B -Dwext -i ra0 -c /etc/wpa_supplicant.conf
[root@akoya ~]# dhcpcd ra0
ra0: dhcpcd 4.0.12 starting
ra0: waiting for carrier
ra0: timed out
I'm not even sure if iwconfig is communicating with this driver (though I can find my router using "iwlist ra0 scan"):
[root@akoya ~]# iwconfig ra0 essid "sodor"
[root@akoya ~]# iwconfig
ra0 RT2860 Wireless ESSID:"" Nickname:"RT2860STA"
Mode:Auto Frequency=2.412 GHz Access Point: 00:21:91:FE:DA:97
And if I try to configure using wicd I see the following log when trying to connect to the wireless:

It is driving me crazy being tied to a cable so I'd really like to get this working... but I'm really not sure what to try. Do I need to rebuild wpa_supplicant? If so is there a package-based way of doing that in arch?
Thanks in advance.

OK... to answer my own questions ...
two questions:
1. Does this mean support for the ralink driver is included by default or *not* included by default?
It seems it means *not*
2. If I uncomment this line then makepkg refuses to build the package because the config file's md5 is no longer valid. How then am I *meant* to make modifications to the build configuration?
right or wrong I used makepkg -g to generate checksums for my modified config file and pasted these into PKGBUILD. It then builds happily. After installing I can run wpa_supplicant with no args and confirm ralink is in the list of drivers. Excellent. But still no success.
Two things I have noticed:
1. wicd places quotes "" around my pre-shared key. If I run wpa_supplicant from the command line and use the conf file created by wicd it reports the PSK as being unparsable. If I remove the quotes then the file is parsed correctly.
2. It doesn't solve my problem :-(

[SOLVED] Help needed with ACPI accelerometer - Acer Iconia Tab W501

Hi,
I am trying to get the accelerometer working on my Acer Iconia Tab W501
In windows, it reported as a BMA150 device, so I have that driver loading on boot.
After months of googling and making a mess in /sys, I still have not got the device working. I was working under the assumption that the device hangs off the i2c bus, but a "lucky google" today uncovered that it is showing up through acpi - acpid is present in my daemons array of rc.conf and the kernel module acer_wmi is also loaded.
The device is certainly sending signals to the kernel. Upon boot, dmesg ends up as follows:
[ 11.689709] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready
[ 12.108374] EXT4-fs (sda2): re-mounted. Opts: commit=0

[ 22.459133] wlan0: no IPv6 routers present
Now, if I rotate the device, and run dmesg again, I have the following:

Yet, running acpi_listen generates the following when the tablet is rotated:
PNP0C14:00 000000bc 00000000
PNP0C14:00 000000bc 00000000
PNP0C14:00 000000bc 00000000
PNP0C14:00 000000bc 00000000
So, it would seem the device is working and sending data to the kernel/drivers, it appears some config is needed to get it properly recognised and an entry in /dev generated.
Really hoping there is an acpi expert around who may be able to help me get the device properly recognised and configures, ideally, as a /dev/input/js*
Cheers.

There is no need to patch the kernel anymore as current kernels have the acer wmi accelerometer patch merged.
Ensure you have the kernel module acer_wmi loading and then the events should be propogated. acpi_listen should show the events.
Using the code from here: http://www.jezra.net/blog/Python_Joysti … ng_Gobject i have written a little daemon that monitors the accelerometer and automatically rotates the screen based on it's position.
Cheers.
[EDIT] Being a laptop, I am guessing the accelerometer is possibly on the hard drive?? used for shock protection?? So if that is the case, I am not sure you will be able to utilise it in the same way as a tablet's accelerometer. There are articles on the web for setting up hard drive accelerometers in linux. The other consideration you need is that the accelerometer may not be on acpi. It could be on the i2c bus (commonly where sensors such as fan speed, core temps etc are located), in which case you will need the i2c driver to get the accelerometer events recognised in the kernel (ensure i2c kernel modules are loaded). So check exactly how the kernel detects the accelerometer, is it on acpi or the i2c bus?[/EDIT]

Help needed in configuring Dynamic F4

Hi All
I am trying to configure Dynamic F4 help for Actvities appln.
In Actvities Appln I have the Partners tab.In this Partner tab I have partner function and partner Id fields. When I make a search for partner Id I need to launch the search screen based on thepartner function selected.
I guess we can use dynamic F4 help but how to achieve this I am not sure. If anyone has done simliar stuff please do give your inputs.
Thanks
Regards
Senthil

Hi Senthil,
You can use Search Help Exit for your problem.
Search help exit : A search help exit is a function module for making the input help process described by the search help more flexible than possible with the standard version.
This function module must have the same interface as function module F4IF_SHLP_EXIT_EXAMPLE. The search help exit may also have further optional parameters (in particular any EXPORTING parameters).
A search help exit is called at certain time points in the input help process.
Note: The source text and long documentation of the above-specified function module (including the long documentation about the parameters) contain information about using search help exits.
Function modules are provided in the function library for operations that are frequently executed in search help exits. The names of these function modules begin with the prefix F4UT_. These function modules can either be used directly as search help exits or used within other search help exits. You can find precise instructions for use in the long documentation for the corresponding function module.
A search help exit is called repeatedly in connection with several
Events during the F4 process. The relevant step of the process is passed on in the CALLCONTROL step. If the module is intended to perform only a few modifications before the step, CALLCONTROL-STEP should remain unchanged.
However, if the step is performed completely by the module, the following step must be returned in CALLCONTROL-STEP.
For more detailed information please refer to the documentation describing the concept of the search help exit.
The module must react with an immediate EXIT to all steps that it does not know or does not want to handle.
Time Points :
During the input help process, a number of time points are defined that each define the beginning of an important operation of the input help process.
If the input help process is defined with a search help having a search help exit, this search help exit is called at each of these time points. If required, the search help exit can also influence the process and even determine that the process should be continued at a different time point.
The following time points are defined:
1. SELONE
Call before selecting an elementary search help. The possible elementary search helps are already in SHLP_TAB. This time point can be used in a search help exit of a collective search help to restrict the selection possibilities for the elementary search helps.
Entries that are deleted from SHLP_TAB in this step are not offered in the elementary search help selection. If there is only one entry remaining in SHLP_TAB, the dialog box for selecting elementary search helps is skipped. You may not change the next time point.
The time point is not accessed again if another elementary search help is to be selected during the dialog.
2. PRESEL1
After selecting an elementary search help. Table INTERFACE has not yet been copied to table SELOPT at this time point in the definition of the search help (type SHLP_DESCR_T). This means that you can still influence the attachment of the search help to the screen here. (Table INTERFACE contains the information about how the search help parameters are related to the screen fields).
3. PRESEL
Before sending the dialog box for restricting values.
This time point is suitable for predefining the value restriction or for completely suppressing or copying the dialog.
4. SELECT
Before selecting the values. If you do not want the default selection, you should copy this time point with a search help exit. DISP should be set as the next time point.
5. DISP
Before displaying the hit list. This time point is suitable for restricting the values to be displayed, e.g. depending on authorizations.
6. RETURN (usually as return value for the next time point)
The RETURN time point should be returned as the next step if a single hit was selected in a search help exit.
It can make sense to change the F4 flow at this time point if control of the process sequence of the Transaction should depend on the selected value (typical
example: setting SET/GET parameters). However, you should note that the process will then depend on whether a value was entered manually or with an input help.
7. RETTOP
You only go to this time point if the input help is controlled by a collective search help. It directly follows the time point RETURN. The search help exit of the collective search help, however, is called at time point RETTOP.
8. EXIT (only for return as next time point)
The EXIT time point should be returned as the next step if the user had the opportunity to terminate the dialog within the search help exit.
9. CREATE
The CREATE time point is only accessed if the user selects the function "Create new values". This function is only available if field CUSTTAB of the control string CALLCONTROL was given a value not equal to SPACE earlier on.
The name of the (customizing) table to be maintained is normally entered there. The next step returned after CREATE should be SELECT so that the newly entered value can be selected and then displayed.
10. APP1, APP2, APP3
If further pushbuttons are introduced in the hit list with function module F4UT_LIST_EXIT, these time points are introduced. They are accessed when the user presses the corresponding pushbutton.
Note: If the F4 help is controlled by a collective search help, the search help exit of the collective search help is called at time points SELONE and RETTOP. (RETTOP only if the user selects a value.) At all other time points the search help exit of the selected elementary search help is called.
If the F4 help is controlled by an elementary search help, time point RETTOP is not executed. The search help exit of the elementary search help is called at time point SELONE (at the moment). This search help exit should not do anything at this time point. Any preparatory work should be carried out at time point PRESEL1.
Steps for creating search help :
1. Run Transaction SE11
2. Give search help name
3. Click on Create
4. Make selection for Elementary or Collective search
 Help
For Elementary Search Help
5. Elementary search Help screen.
6. Give short description.
7. Dialog type specifies the data display in the hit
 list.
8. Give selection method
A] Search for database tables
B] Search for Views
9. Hot key specifies the letter or number displayed with every elementary search help.
10. Search help Exit: Specify the function module developed for the search of data for the elementary search help.
11. Search help parameter
A] Specify the input and output fields in the search help parameter column.
B] IMP column is input parameter for the search help.
C] EXP column is output parameter of the search help, to be displayed in the Hit list after selection.
D] LPos specifies the order in which fields are displayed in the hit list.
E] SPos specifies the order in which fields are displayed in the search help pop up screen.
F] Specify Data element in the field.
G] Specify the default value for any field required.
For Collective Search Help :
12. Search help exit: Specify the function module developed for the search of data for the elementary search help.
13. Search help parameter: Specify the import and export parameters.
14. Search help: Specify the elementary search help and the short text.
15. Parameter Assignment: Select the elementary search help and click on the parameter assignment. System proposes fields. User has to select the fields as per requirement, fields to be displayed in the output
hit list. Parameter assignment has to be done compulsorily for every elementary search help designed for the collective search help.
Please reward points if it helps.

Help needed with configuring D-Link DSL-320T

My home network consists of 2 Aiport Express using WDS, 2 PowerBooks and a WiFi HP printer.
I recently had to replace my trusty Aztech DSL modem/router when it died, and bought a D-Link DSL-320T.
This is a DSL modem but NOT ROUTER with a built in DHCP server, but connection behaviour is different from my old device. The IP address for the modem is the default 192.168.1.1
When I connect the modem with an Ethernet cable to the Airport Express, run AirPort Admin Utility and set TCP/IP to configure using DHCP, the IP address of the AE becomes the fixed IP that my ISP has assigned to me, which starts 212.xxx.xxx.xxx. The router address is the same (212.xx.xxx.xxx), and the subnet is 255.255.255.255
With my old modem/router, the AE's IP address would be 192.168.1.2, and then I would use the AE as a wireless bridge, so that the modem would be the DHCP server. All connected Macs and printer would have a 192.168.1.xxx IP address.
With the new modem, I am unable to share the connection unless I use the AE to distribute IP addresses using NAT and DHCP. The AE uses the 10.0.1.xxx range of IP addresses. So my PowerBook has an IP of 10.0.1.xxx
I keep on having to restart the modem as the connection seems to drop on me, to the extent that I cannot even open the modem configuration page by entering 192.168.1.1 into Safari.
My suspicion is that having 2 DHCP servers on the go is not helpful, trying to be on a 192.168.1.x range of addresses as well 10.0.1.x.
I'm not really sure what purpose the modem's DHCP server has, because it does not seem to distribute 192.168.1.x IP addresses, if I configure the AE to be a wireless bridge. As I have said, it is not a modem/router but a modem only. I cannot set up any port forwarding (NAT) instructions. The D-Link manual and website are not very helpful, but it does appear that the correct behavior is for the connected device to display the public (i.e. 212.xxx.xxx.xxx) address. The website does also state that I would need to have separate router to do NAT. I thought that is where the AE comes in...
However if I disable the modem's DHCP server I am not sure what manual settings to configure the AE with.
Any help much appreciated!

AirPort Express. Base Station V6.3 Mac OS X (10.4.8) PowerBook G4

The IP address for the modem is the default
192.168.1.1... The router address is the same
(212.xx.xxx.xxx)...
This is confusing. Which IP address does your D-Link
use?
The D-Link uses the IP address 192.168.1.1
Whatever device is plugged into the D-Link, whether PowerBook directly or the AirPort Express, configured using DHCP you get the following in TCP/IP:
IP address: 212.xxx.xxx.xxx
Subnet Mask: 255.255.255.255
Router: 212.xxx.xxx.xxx (identical numbers to IP address)
DNS servers: as per ISP
My
suspicion is that having 2 DHCP servers on the go is
not helpful, trying to be on a 192.168.1.x range of
addresses as well 10.0.1.x.
There is no inherent problem using 2 DHCP servers.
If I can have both devices acting as DHCP servers, then maybe there is a different explanation for why I lose connection all the time which is only cured by turning the modem on and off again?

Urgent help needed in configuring X1151A for RAC cluster

for RAC requirements I have to configure this card to use the interface name of ce1 but I have tried changing slots and puting /etc/hostname.ce1 file out there but it fails .. it always comes up as ce0.
my question is : How can I cofigure this card to come up as ce1 ? in the other box I had to do nothing .. i just placed the /etc/hostname.ce1 file with hostname and it works perfect.
can you please email me a copy of your response at [email protected] ?
thanks

Look for "ce" instances in the /etc/path_to_inst file. You'll need to change the lines so that the hardware path you want is "1".
Keep a backup and write down the pathname. You can give that path to a 'boot -a' prompt if anything bad happens.

For the discussion in this forum thread, the path-to-inst file
can be though of as a repository of every device path
for every lump of hardware that was ever installed to a system.
It tells Solaris where to find the devices, along their communication interconnect paths.
Thus a device driver can know where to sends its commands
and where to listen for any return signalling responses from the device.
Issues can arise if a device was successfully installed to a path,
such as when a PCI card is installed to a particular slot,
and that card gets moved to another slot.
The path-to-inst file will "remember" the old path, in case you return the card.
No software structures need to be re-built when it reappears in its old slot position.
The former functionality is maintained if ever needed again.
The new position initiates a new entry into the file,
such as when there are two of the same cards instead of the original solitary card.
For your circumstances, there's got to be something in the computer's configuration
that can isolate the data streaming to IP address #1 ( such as for ce0 )
from whatever data might need to go through the other IP address ( such as for ce1 ).
My suggestion for you is to use the devfsadm command.
Review its man pages.
Decide how you want the computers to be configured -- probably using ce0 on both.
devfsadm -C will purge out stale entries and rebuild the path-to-inst file.
A reconfiguration reboot, such as might result from a boot -r,
only appends new device instances to the file.
There's no cleanup, or 'housekeeping', done to it.

Help needed in configuring AirPort Express for Warcraft!

Will someone talk me through how to configure my AirPort Express so that I am able to play Warcraft? The downloader is telling me that I'm behind a firewall, however I have configured my Firewalls on my computer to allow Warcraft, and it's still not really working.
I'm not the most tech-savvy, any help would be greatly appreciated.

Thank you Duane and others.
This is a very interesting discussion group with a lot of AX users having problems for one reason or another. The main frustration is with, at least for me, the intermittent functionality. As opposed to my wireless laptop, which connects with the network each and every time I turn it on, the AX is good about 75% of the time. And in turn, if iTunes or the Airport Utility can't see the AX there's absolutely nothing you can do to get it to, short of rebooting the laptop, restarting iTunes, etc.
My next plan is to move AX rather close to the wireless router to ascertain if signal strength is the issue.
And I have 'one' last question, are there people out there that have 100% success all the time using AX, especially for streaming iTunes?
Thanks again.

Desperate help needed to configure WVC210 for remote access?

Hi, I'm new and desperately need some help on setting up my WVC210 for remote access.
I manage to setup and see images from my WVC210 using my home LAN via both wired and also wireless.
I have 2 questions:
(a) for wireless connection, i only manage to get connection to my WVC210 if i disable the wireless security from my router. But that means i'm opening my wireless LAN to everyone. How can i still get connection to the camera if i enable the wireless security from my router. (FYI: my router is 2Wire ADSL from Singnet Mio)
(b) how can i get connection to my WVC210 from outside or in my office? I type in the camera Fixed IP address (displayed on the front screen) on the web browser, by it shows a error page. Is there some setting that i might need to adjust ?
Pls kindly help me
Thank you.

Bernard,
For Item (2) is there any difference between the camera built-in dyndns updater versus the software updater? I am under the impression that the software updater is easier to manage.
The biggest difference for you is that the camera always stays at the same location, and the laptop goes with you. Every time you access the internet from a different location with the laptop the software updater is sending the new IP address to dyndns.com. This causes you to lose access to your camera because the FQDN doesn't point to your home IP address anymore. Once the dyndns credentials are in the camera (or router) there is no management needed. The device will automatically update dyndns.com with your new IP address as it changes, and you do not need to do anything.
For Item (3), are you saying port forward 1025 is it for the 2nd camera only or for both? Or is it 2nd camera use 1025 and first camera use 8080?
Here's an example of what I mean:
Camera 1: 192.168.1.210 port 1024. In router, forward port 1024 to 192.168.1.210
Local Access: http://192.168.1.210:1024
Remote Access: http://bernards210.dyndns.org:1024 (Example)
Camera 2: 192.168.1.211 port 1025. In router, forward port 1025 to 192.168.1.211
Local Access: http://192.168.1.211:1025
Remote Access: http://bernards210.dyndns.org:1025 (Example)
Camera 3: 192.168.1.212 port 1026. In router, forward port 1026 to 192.168.1.212
Local Access: http://192.168.1.212:1026
Remote Access: http://bernards210.dyndns.org:1026 (Example)
to access the 2 camera outside, do i have to have another dyndns host name or can i use the current one for both camera?
As you can see in the above example, the dyndns name remains the same for remote access to all three cameras. The only change is the port number at the end. Your router will translate the port number to the IP address that the port is forwarded to, allowing you to select the camera that you wish to view by changing the port number in the address.
I was actually thinking that the camera web browser can show 2 camera at the same time. Is it possible?
No. Each browser window will display a single camera. You can however opens multiple instances of your browser to allow viewing of more than one camera simultaneously. A better solution is to install the Video Monitoring Software that is included with the camera which allows you to view multiple cameras in the same window.

Urgent help need on configuring MPLS TE

i found that CSPF is not finding other path still there is no bandwith on SPF path and tunnel1 remain down if i down second tunne2 then tunnel 1 comes up not try to use other interfaces which r free with enough bandwidth. all router have MPLS TE and RSVP.
please read all in detail below
my freinds i have one Q. for MPLS TE. i m using 3660 router for MPLS TE on dayanagen simulater. in this lab there is 5 routers with 512 kbp RSVP on each interface all router with MPLS TE. configure are as->
R1 /0 ---R2 /0
R2 ==== R3 have Two interfaces s1/1 and s1/3
R2 /2-----R5 /2 interface connection
R3 ---- R5 int connection
R3 ---- R4 tunnel to R4 from R1,R2 with 300kb each
tunnel1 on R1 to R4 with 300kb rsvp TE
tunnel2 on R1 to R3 with 50kb rsvp TE
tunnel1 on R2 to R4 with 300kb rsvp TE
diagram like that below (ignore ..dots)
R1---R2=====R3----R4
.......I_______I
..........R5
i created tunnels from R1----> R4 with 300Kb.
second R1---->R5 with 50Kbp tunnel
and
on R2---->R4 tunnel with 300kbp.
PROBLEM IS when R1 tunnel go via R2 to R4 it takes s1/1 interface with 300rsvp. means for R2 tunnel should find next interface for same destination R4 becaused there is not enough space.On one of remaining on interfaces on R2 s1/3 or S1/2 but R2-->R4 tunnel remain down. when i down R1---R4 tunnel R2--R4 tunnel comes up on same interface. NOW when i up R2 tunnel first and later R1. then same thing again R1 down and wait for R2 tunnel to go down.then up on same interface. if u see there is still two path r free to go R4 on R2
1. R2 s1/3 ----> s1/3 of R3
2. R2 s1/2 ---->s1/2 of R5 with both 512 kb RSVP
there is using R2 s1/1 for tunnel
why not with help of CSPF it takes other path when 512 link is also free on R2 router to same destination??? its on dyanamips is it can problem with simulater.
it means that on R2 using SPF path for R4 for both tunnel and not trying to find other CSPF path thats why my two interfaces are free with 512kbp RSVP on same router R2. why not CSPF using other remaining path. and down one of tunnel because of there is no space on tht s1/1 interface........
PLZZ ANSER ME I NEVA USE MPLS TE B4
thanks in advance!

sorry m8 for late reply i had sort the problem. it occur because i was using 4 router now when i used TE with 12 router on daynagen it is working fine.
Question
now i have one question. i am trying to use TE with MPLS VPN site to site. as you know site to site MPLS VPN send traffic both way from R1 to R2 and R2 to R1.
but if i create MPLS TE tunnel1 on R1 to destination R2 then all traffic from R1 will go via tunnel1. but traffic from R2 wil go to R1 via normal route becasue tunnels is one way onli can see on R1
that means i have to create tunnels at both end in opposite directions. please reply me.
MPLS VPN site to site between R1 --- R2 have to create tunnels for both direction because tunnel work in on way?
R1 ---->R2 tunnel1
R1<-----R2 tunnel2
thanks

[SOLVED] Help needed with iptables rule with unusual setup

Hi I recently setup hostapd on my netbook so I could share a wireless network with my phone and I'm having trouble because my netbook is also hosting a Jetty sever (Subsonic media streamer).
My setup is as follows
[CABLE MODEM]===[WIRED ROUTER]=====[NETBOOK] ))))) [PHONE]
The wired router provides the DHCP server.
On my netbook I created a (br0) bridge between eth0 and wlan0 and started hostapd. That all works fine when I'm not trying to host my Jetty server on my netbook.
The netbook has the IP 192.168.0.8
The phone has the IP 192.168.0.6
I do not want to give the Jetty server root permissions just so it can run on port 80. So instead I start it instead on port 4040 and then use a iptables rule to redirect connections to port 80 to port 4040.
Before I setup hostapd on machine I used to use the following.
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 4040
However when I'm using hostapd and try to access websites on my phone its web browser is ALWAYS REDIRECTED to my jetty server. I'm not really surprised at this as the rule I mentioned above is for any destination or any source.
I tried this rule:
iptables -t nat -A PREROUTING -d localhost -p tcp --dport 80 -j REDIRECT --to-ports 4040
This didn't work. On my phone I could access websites as expected but nobody (tried external from network and internally) could access the jetty server on port 80. Does anyone know why this rule doesn't work?
I tried this rule:
iptables -t nat -A PREROUTING \! -s 192.168.0.6 -p tcp --dport 80 -j REDIRECT --to-ports 4040
This rule worked (Redirect port 4040 connections to port 80 if the connection isn't from my phone). But this is NOT very good at all as it means I would need a separate rule for every wireless device that connected to my netbook (via hostapd). Also if the IP address of my phone ever changes this rule becomes useless too!
Does anyone have any ideas?
Any help would be greatly appreciated.
Thanks.

Well looks like I fixed my own problem.
I added a LOG target in the PREROUTING chain like so
iptables -t nat -A PREROUTING -p tcp --dport 80 -j LOG --log-prefix 'cheesy-redirect'
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 80
When I looked at /var/logs/everything I noticed this.
dan-netbook kernel: cheesy-redirectIN=br0 OUT= PHYSIN=eth0 MAC=00:26:18:73:ea:28:00:09:5b:5d:0a:33:08:00 SRC=178.102.41.92 DST=192.168.0.3 LEN=52 TOS=0x00 PREC=0x00 TTL=46 ID=51411 DF PROTO=TCP SPT=48219 DPT=80 WINDOW=49640 RES=0x00 SYN URGP=0
The destination is 192.168.0.3 ! Which is very very weird. This the IP address I had told my router to give my eth0 card in the past when I wasn't using a network bridge (br0). I was connected to the network using 192.168.0.8 on br0. The eth0 interface wasn't assigned an IP address.
192.168.0.3 was also the IP address I setup for static port forwarding (which I forgot about) so when I accessed my jetty server from outside my network all packets would of been forwarded to 192.168.0.3
I should never of received those packets as I was 192.168.0.8 not 192.168.0.3 at the time of logging so how I even received these packets is a mystery to me. Maybe the router software is buggy
Fixing was pretty straight forward I changed the port forward to go to 192.168.0.8 and then tried connecting to the jetty server externally and noted in the log
cheesy-redirectIN=br0 OUT= PHYSIN=eth0 MAC=00:25:d3:46:4d:0d:00:09:5b:5d:0a:33:08:00 SRC=178.102.41.92 DST=192.168.0.8 LEN=52 TOS=0x00 PREC=0x00 TTL=46 ID=65326 DF PROTO=TCP SPT=33597 DPT=80 WINDOW=49640 RES=0x00 SYN URGP=0
So the correct redirect rule is
iptables -t nat -A PREROUTING -p tcp --dport 80 -d 192.168.0.8 -j REDIRECT --to-ports 80
which works nicely
One last question though. Does anyone know how I can use a hostname rather than 192.168.0.8 which points to whatever the IP address of br0 is set to? localhost points to 127.0.0.1 so that doesn't work.

[Solved] Help needed with getting fonts antialiased.

Greetings. I'm in the process of installingArch and I must be missing something as fonts just aren't antialiasing. Any help would be appreciated. I'm using the Fonts guide on the wiki. Here's the steps I did:
pacman -Rd libxft
yaourt -S fontconfig-lcd cairo-lcd
pacman -S libxft-lcd
Freetype is installed and I linked what I could to /etc/fonts/conf.d/:
10-autohint.conf 40-nonlatin.conf 65-nonlatin.conf
10-sub-pixel-rgb.conf 45-latin.conf 69-unifont.conf
20-fix-globaladvance.conf 49-sansserif.conf 70-no-bitmaps.conf
20-unhint-small-vera.conf 50-user.conf 80-delicious.conf

30-metric-aliases.conf 60-latin.conf README
30-urw-aliases.conf 65-fonts-persian.conf
I've tried changing settings in the KDE control center from "System Settings" to Enabled, started a new app. But no luck. I've created a basic ~/.fonts.conf that has antialiasing and hinting, logging out and logging in again to no avail. What got me was that fontconfig didn't install a 10-antialias.conf:
10-autohint.conf 25-unhint-nonlatin.conf 60-latin.conf
10-no-sub-pixel.conf 29-replace-bitmap-fonts.conf 65-fonts-persian.conf
10-sub-pixel-bgr.conf 30-metric-aliases.conf 65-khmer.conf

20-fix-globaladvance.conf 50-user.conf 80-delicious.conf
20-unhint-small-vera.conf 51-local.conf 90-synthetic.conf
Is this the problem? Obviously I'm missing a step here. Any ideas, what do I need to do?

Dallied through the thread and didn't find anything. No luck thus far. Looks like this is a system-wide problem as KDM in not antialiasing. Change to a new ~/.fonts.conf:
