RIP V2, network command with classless address yield to classful

As we know that RIP V2 is Classless while V1 is Classful.
Obviously there are other differences. Cisco has mentioned them in CCNA3 V3.1 Article 1.2.3
RIP V2 supports prefix routing with VLSM so different subnets within the same network can have different subnet masks.
A(config)#router rip
A(config-router)#ver 2
A(config-router)#network
A(config-router)#network 172.16.2.0
A(config-router)#^Z
A#sh run
*Apr 7 05:36:29.422: %SYS-5-CONFIG_I: Configured from console by console
A#sh run | b router rip
router rip
version 2
redistribute eigrp 12 metric 2
network 11.0.0.0
network 172.16.0.0
network 192.1.14.0
Why has the value been changed from 172.16.2.0 to 172.16.0.0 ?
What is the point of using RIP V2 if it yields to same result as RIP V1 ?

Although ripv2 is classless, the configuration of which interfaces are attached to the rip process is classfull.
In this case of yours, all interfaces configured in the range of 11.0.0.0/8, 172.16.0.0/16 or 192.1.14.0/24 will be attached to the rip process. If an interface exists with subnet 172.16.2.0/24 it will be advertised as such.
Hope this helps,

Hi Marcelo,
Yes this is normal, a default route unlike any other routes is not redistributed between routing protocols by default, in the case of BGP you have 2 options, either use a network command and make sure that the route is in the routing table (via EIGRP in your case), or use redistribute + default-information originate, you can test this by removing the network command and adding the default-information originate under the address family.

Network setup 'DHCP with manual address' changes to 'Using DHCP'

I have setup my local network with a manual address and have observed that the setting changes without my doing to simply Using DHCP. I can't get the setup to continue using a manually assigned ip address. Even though I've saved the network settings preferences, they revert to 'Using DHCP'. Any ideas? Thanks in advance.

If you "have setup (your) local network with a manual address," does that mean you have disabled DHCP in your router? If so, then you'd want to configure "manually" in your Sys Prefs > Network.
Or did you mean that you have setup a computer on your local network with a manual address using DHCP? (And that your router has DHCP enabled?)
If the router's DHCP is enabled, many routers will allow you to set aside a subset of IP addresses to the DHCP pool, and the remainder are, by definition, reserved for static addressing. Are you assigning the computer requiring a static IPA (but using DHCP defined gateway and subnet) an address falling within the static address range of your local subnet?
If you can't partition the address space between static IP addresses and DHCP-assigned IP addresses when DHCP is enabled, are you assigning a high-numbered IP address to the computer whose Sys Prefs has DHCP with manual address?

Leopard : Network : Unable to use DHCP with manual address.

After installing Leopard on my Macmini (PowerPC 1.42Ghz, 1GB RAM, 80GB HDD), I found my IP address obtains different IP address than Panther and Tiger use. Then I go into System Preferences -> Network -> select Ethernet -> select "Using DHCP with manual address" in the "Configure" combo box, and change the IP address from 192.168.0.8 to 192.168.0.100. Once I hit apply, the network connection never comes back. There is no complaint that another computer is using the 192.168.0.100 IP address. This works if I am using Panther or Tiger on the same computer.
Any help is appreciated.

Setting the DHCP to a number you want to use can be very useful in a busy environment. I usually choose to use numbers that are outside of the range of numbers being controlled by my router (Westell).
Port Forwarding for services like ARD, Azureus, or any server application break when the IP number changes for any reason.
Some routers will not allow numbers outside of a restricted range of numbers that can be set up in the router configuration menu's. In this case, I find out if the router is assigning numbers from the high or low end and make sure I assign numbers at the opposite end of the range.
My Westell router does allow me to use numbers other than the range of 50 numbers it has been told to use for DHCP, but I have also encountered problems when trying this on a wireless connection.

Mac is not connecting to network systems with names it's only connecting with the IP address why?

Mac is not connecting to network systems with names.
It's only connecting with the IP address why?

It sounds like a problem with the domain name server. Be sure you are using the correct DNS in System Preferences > Network, and if you are make sure it is functioning correctly.
Best of luck.

FTP STOR command with REST capability

Hi folk,
I have a cRIO on a remote field, and I need that the program running on that platform periodically uploaded, through the internet, the data files to an FTP server.
I have used the FTP VIs included in the Internet Toolkit to develop this functionality and I am experiencing some problems.
During the uploading of files of medium or large size, via FTP, can happen that the FTP server closes the connection.
The reasons can be different, network operation exceeded the user-specified or system time limit, bandwidth usage is restricted or the bandwidth is limited, etc..
To overcome this issue the correct strategy is to reopen the FTP connection and to restart the upload from the point where it was interrupted.
It is very important to finish to upload only the remaining part of the file, and not to restart from the beginning, otherwise you could not end the upload if the FTP server closes the connection again and again.
For implementing the resume, the FTP protocol supports a number of commands:
SIZE <remote file-name> Returns the size of a file (Binary mode) .
REST <file-size>         Sets the following STOR command to restart transfer
                         from the specified point.
STOR <remote file-name> If anticipated from a REST command, store (upload)
                         only the part of the file starting from the
                         specified point.
At the present, it seams to me that the LabVIEW Internet Toolkit does not support the capability of FTP resume.
Furthermore, if during a FTP upload the connection is closed by the FTP server, the FTP [STOR].vi exits sometime with ambiguous errors.
Exit with a correct error:
Error 56 occurred at TCP Read in NI_InternetTK_Common_VIs.lvlib:TCP Read xTP Reply.vi:2->NI_InternetTK_FTP_VIs.lvlib:FTP Get Command Reply.vi:1->NI_InternetTK_FTP_VIs.lvlib:FTP Data Send.vi->NI_InternetTK_FTP_VIs.lvlib:FTP [STOR].vi
Possible reason(s):
LabVIEW: The network operation exceeded the user-specified or system time limit.
Exit with an ambiguous error:
Error 54 occurred at TCP Open Connection in NI_InternetTK_FTP_VIs.lvlib:FTP Open Data Connection.vi->NI_InternetTK_FTP_VIs.lvlib:FTP Data Send.vi->NI_InternetTK_FTP_VIs.lvlib:FTP [STOR].vi
Possible reason(s):
LabVIEW: The network address is ill-formed. Make sure the address is in a valid format. For TCP/IP, the address can be either a machine name or an IP address in the form xxx.xxx.xxx.xxx. If this error occurs when specifying a machine name, make sure the machine name is valid. Try to ping the machine name. Check that you have a DNS server properly configured.
Do you have idea or suggestion of how realize an FTP STOR command with REST capability?
Thanks,
Asper

Unfortunately the best advice I could give you would be to make a copy of the FTP toolkit and add this functionality yourself. You should have most of the building blocks available to you so it should be fairly starightforward. You could reference the RFC (RFC 959 and RFC 3659 for extensions) for any specifics you need on the packet format. You will need to save some state information so you can resume your download from the correct point.
Would it be possible to use TFTP? This is much leaner and more likely to succeed if the other ends supports it. I recently wrote a very basic TFTP Write. I'm sure I could do the TFTP Read in short order. I'm still working on packaging it up in a distributable form but I could provide you with a basic VI if needed.

I have an issue with the address browser in mail in Yosemite

I am using IOS 10.10.1 now on an iMac and have discovered an issue with the address browser in mail.
Previously in my pending to send email toolbar there was a contacts icon which I clicked on to display my contacts list. I could hold down the Command button and select as many contacts I wanted (often up to 100), then select the field to send (to, ccc, bcc) and the contact would appear.
Now, I have to click the + sign at the end of the field line, and select recipients one at a time. Not only that, but I have to click twice to get to the email address, once on the name and then the email address drops down under the name and then I click on the email address. When I do that the drop down box disappears and the recipient's email address goes to the field. I have tried all combinations of buttons to be able to choose multiple addresses but haven't found the right one yet.
An Apple Support guy told me to open my regular Address book, and hold down the command button to choose multiple recipients then drag them to the field on my already opened send email.
This is one way around the issue (which wasn't an issue in Mavericks) but where some recipients have two or more email addresses listed in my contacts it means I have to manually go through the finished list on my emails to make sure the most desired one was selected. What a pain.
Also, previously, where I was sending out many emails and wanted to stop say half way down my list, and send, I could come back to that list for the next email and see where I'd got up to.
I don't want to make groups because my recipients vary depending on what I am sending so my lists change constantly.
Any suggestions?
Last point...who archives? On my regular email page I now have the Archive icon to the left of my Delete icon which I would prefer was to the left, first in the line as this is the icon I use mostly. With Folders, my Sent and Trash lists, who needs to archive?
Cheers,

I can help you only with the placement of the icon placement -- if you right-mouse click on the toolbar, then select Customize Toolbar, you can move an icon to where you want it to be.

I'm hooked up to the ethernet using DHCP with manual address. It's running (green) but my internet (Safari, messenger, email) doesn't work! Help!

I'm running an iMac with Mountain Lion. Not only do we do accounting work on this computer with AccountEdge, but the computer functions as a server to another computer in a different state.
Anyway, I set a static IP address (Using DHCP with manual address) on it (to allow for a VPN to the computer in the different state) and it is connected (green dot) - meaning that the other computer in the different state can connect to us via that ethernet line - but for some reason Safari, Messanger, and Apple Email won't work.
But if I switch a dynamic IP (DHCP auto), I can use the internet (Safari, messanger, email), but the computer in the different state can't connect to this computer.
How can I fix this so that the computer in the different state can connect to this computer and that the internet (Safari, messanger, and email) can work at the same time?
Much thanks!

No but if they are using a VPN Tunnel for the connection that restricts all internet traffic over the tunnel. Which means you can't use that same computer to broswe the internet or connect to other computers or devices on your LAN.
I'd need to see the actual setup, router and the IP addresses you are using.
Networking and remote networking is fairly easy when you are in front of the systems you are working on. Doing it over the internet on a forum is almost impossible. Tha is why I suggested you get local help, like the person that originally set it up.

How do I set up different network locations with different wifi?

I am having an issue setting up different network locations with different wifi profiles on each. I want to do this to enable fast switching of wireless networks. In my house I have two wireless networks, my own personal one and one that is created by using a wifi modem supplied by my company. If I use the company wifi network then I can get into all my work applications without having to enable VPN access separately. It is also faster. However, they also block many applications including sending email from my personal email account, dropbox, etc. So throughout the day I need to switch wireless networks back and forth.
I was looking for a faster way to switch and thought I would try network locations. Was able to set up a new network location without issue. However it seems that whatever wireless preferences, changes, or wifi network order I put into my "Work" location it carries over to my other location which is the standard "Automatic".
What I would like it to have my "Work" location only to be able to connect to my work wifi and my other network (Automatic) to just connect to my home wifi only. That way I can enable faster wifi switching and can even use my launcher program (Alfred) to provide shortcuts.
Anyway to do this?
Thanks in advance for any help or advice.

Just thought I would bump this up in the conversation. Doing a further search I came across this discussion which is similar: Connecting to a wireless network via applescript?
However, I tried to build the Automator application as discussed and cannot get it to work. Very much a novice at Applescript and Shell Script but have created customized Automator services before. All I get now is "Shell Script command encountered an error". No more detail. I copied and pasted the script as shown in the email thread. Is there any other line or command I need to place in front of it?
Thanks again for any help

Opening a Browser Window with no Address Bar

Hello All,
I am working on an application which needs to open a new browser window. I need to hide the URL from the user.
Right now, I can open the window with no toolbar or address bar with the following command:
String cmd = "cmd.exe /c start javascript:window.open('http://www.google.ca','main','menubar=0,location=0,toolbar=0,personalbar=0,status=0,scrollbars=1,resizable=yes')";
However, this first opens up a blank window and then the window with no address bar. If I make the command:
String cmd = "cmd.exe /c start javascript:window.open('http://www.google.ca','main','menubar=0,location=0,toolbar=0,personalbar=0,status=0,scrollbars=1,resizable=yes';window.close();)";
then the user is asked if they wish to close the first blank window.
Does anyone know how to open a new browser window via the command line without the annoying extra window?

It works with the following command but the new browser window isn't in "focus".
cmd.exe /c start javascript:window.open('http://www.google.ca','main','menubar=0,location=0,toolbar=0,personalbar=0,status=0,scrollbars=1,resizable=yes');window.opener=top;window.close();

How to use both wired and wireless connection with static addresses

Now that I have setup my home network with static addresses (router, mini1, mini2 and PC) in the way I want, (big thanks to BDAqua http://discussions.apple.com/thread.jspa?threadID=1271635&tstart=0) I would like to understand some more advanced network concepts.
I would like to change the network so that I use both the wireless connection and the built-in ethernet connection at the same time in my Mac mini1. I would like to connect my PC to my Mac mini by using the wired ethernet connection so that I reach the Internet from my PC as well. I would also like to be in control of all the addresses therefore I want to assign the addresses manually.
The question: What addresses should I use between mini1 and PC? Should I use the same wireless address space as I already use between the wireless router and the other computers (router: 192.168.1.1, mini1: 192.168.1.101, mini2: 192.168.1.103) or should I use something totally different like 10.X.X.X? What should I put in ethernet connection "Router"-field, the same as in Airport (192.168.1.1)? What about DNS, same as in Airport?

If I understand this correctly, you wish your Mini to perform Internet Sharing for your PC, correct!?
If so you'll pretty much have to let the Mini handle DHCP & NAT on the Ethernet port. You also want to be sure Airport is dragged to the top of Network>Show:>Network Port Configurations, that's what position the Mini will use 1st for Internet itself.
On the Mini turn on both Web Sharing & Internet Sharing. The PC once connected will have the Mini's Ethernet IP as it's Gateway addy.

Tcp/ip write help - need to send a motor command with parameters

hello - i have one small, main labview 7.0 vi that i use to control a drill's two motors.
right now i press a button on the front panel to move the motor, and when i do, a sub vi window pops up so the operator can set a couple of parameters and press an ok button.....the vi then sends the command with the parameters to the drill's motors.
i am trying to change it so i can send the move command from another computer, in another room, while the main vi sits on the computer with the drill. i know i will use TCP listen, write, read, and close in both the main vi (the TCP server?) and the client which is on the remote computer.
my problem is with setting the parameters for the subvi's that usually pops up. how do i set the parameters from the remote-client and have them be sent into the subvi on the main vi. if i can do this, i would have to also have a way to close the sub vi after it pops up in the main program too.
OR should i use something else like and application reference or an invoke node function?????
please help
thanks!!!!

Hi again,
If the VI in the lab will be running continuously, then you will need
to alter some things from the example I sent you or look at an
alternate implementation. The example I sent you assumed that the VI in
the lab was not running. This technique actually starts the VI and runs
it somewhat like a subVI. It inputs values into the connector pane,
runs it, and then returns values from the outputs on the connector pane
after it finishes executing. It will not work to call a VI by reference
if it is already continuously running.
Instead I imagine you would want to have your VI in the lab have some
sort of State Machine that polls a certain control value, such as an
enum control, to determine which state to execute next. You could
modify the technique I first sent to still open a reference to the VI
in the lab, but it wouldn't try to run it. Instead you could use the VI
method Set Control Value to set the value of a certain control or
controls in the lab VI to certain values. The VI in the lab would then
hopefully be in some Idle state where it polled one of those control
values continuously to decide what to do next. That would allow the VI
in the office to programmatically send commands to the other VI, as
well as parameters for those commands. Simply set control values for
the VI in the lab and let the VI in the lab go about its business. I've
attached an example below.
That's just one idea. Other options you have would be to use a
DataSocket connection to send parameters and commands back and forth
between computers. This is a pretty simple API to use. If you have
LabVIEW 8, Shared Variables are an option. Or you might look into
simply using Remote Front panels, which allows you to connect to a VIs
Front Panel across the network. You could then have the whole VI in the
Lab, but you could connect to it, view it, modify the controls and so
on from your office. If you want to view and control a VI without
having LabVIEW installed on the viewing computer, you can use the Web
Publishing Tool to create a web interface for your front panel. Lots of
options. Let me know what sounds interesting.

WiFi Network Name with Underscore Special Characters Issue

Turns out that iPod Touch doesn't like wireless network names with special characters (e.g. underscores) in them (I had 2 underscores in mine).
It will establish a connection, get an IP address, even use WEP but won't talk to the Internet if the wireless access point name has an underscore in it. If you can change your wireless network name to remove the special characters the iPod Touch becomes very and will connect using the Internet.

I'm looking for a way to escape all characters (not only the minus sign) except for a specific character. Kind of like 'unescaping' a specific character (the '%' sign) within braces {}What about if you apply a function like regexp_replace to escape all known "specific characters", and then unescape the particular specific character again back as e.g. in
SQL> select 'a.da-df%df*' str, replace (
                                               regexp_replace (
                                                    'a.da-df%df*',
                                                    '([[:punct:]])',
                                                    '\\\1'
                                               str2
from dual
STR         STR2
a.da-df%df* a\.da\-df%df\*
1 row selected.i.e. don't escape with curly brackets but with the backslash character.
You can then use this string in your query like in
WHERE CONTAINS(r.POI_NAME, '<query> <textquery grammar="context"> <progression><seq>'
||'aaab'
||'</seq><seq>'
||'aaa\-b'
||'%</seq></progression> </textquery> </query> ' ,1)> 2

Networking troubles with ABIT BP6 board and Solaris 8

Hi, Im trying to install the Solaris 8 software on my ABIT BP6 board with a Compaq NetFlex3 10TX NIC. This is a SMP board (dual celeron) but is not on the HCL (the NIC is).
The installation gives no problems at all (except for a memory conflict between memory devices), and SunOS works pretty well except for networking... using ifconfig -a shows me the networking interface and the loopback interface but I can't ping outside of the Solaris machine (or ping to the Solaris machine from an other machine).
I know that the board is not on the HCL but I had no networking troubles with Solaris 8 early access.
After instalation of the software and the reboot, I get the status as below:
>

The system is coming up. Please wait.

As you can see I get a time out while configuring the NIC. I tried a lot of different things (and some bad ones like using the device driver disk of the EA version with the cd's of the final version but no luck there...)
Anyone with the same problems or any help?
Thanx, Marcel

Hi maeck,
I'm sorry that my message is off the topic. Could you help me with a problem that I have with Abit BP6 + Solaris 8 combo?
I'm encountering error message on console screen during booting/reboot/shutting down like "APIC error interrupt on CPU 0. Status=2" where CPU can be 0 or 1, status can be 0, 2, 4 or 6.
If I let my dual Celeron400 run at 400MHz, the frequency of errors is few and far between. Though it still happens. If I overclock them to 558MHz like I udually do, it will show at least 4 times during a booting process. I've tried MPS 1.1 and 1.4 settings. I've also tried turning off all cache, delayed transaction, passive release settings.
In addition, the overclocked system tends to lock up while it runs flawless in Windows 2000 Professional and Redhat 6.1. Do you have any similar experience?

How to configure BODS in network environment with NAT ?

Hi Team,
Now we are working on POC of BO Data Services 4.0 with SI partner and they reported us that a communication error (error code:BODI-1241023) occurred when they started a job from Designer.
They can do it without any problems in the following two cases.
1. from Designer which is installed in the CMS/JobServer machine
2. from Designer which is installed in local PC within internal network (without firewall / NAT)
That is, the cause is Firewall with NAT(Network Address Translation) between Designer and JobServer/CMS.
And, they can log on to CMS/JobServer with NAT environment, however, cann't start a job from Designer.
The port #3500 for JobServer is open. They confirmed that they could log on to the JobServer in the event log
of the JobServer.
That is, Designer -> CMS/JobServer communication is OK, but JobServer -> Designer communication must be NG.
Could you advise us how to configure BODS both client and server sides in the network environment with NAT ?
Thanks and best regards,

HI Buddy,
You can achieve this by $FLEX$, create first value set, and assign it to first field. Create second value set based on first value set using $FLEX$.
