Routes, gateways, and networks -- Help Please

Hi Linux gurus:
I have a problem that I know you will help me resolve...
I have two network cards in my Linux box.
1. public network:
10/100
192.168.1.102
default gw: 192.168.1.1
netmask: 255.255.255.0
I want this one routed to my router for internet/public use
2. private network 1000mpbs
192.168.2.181
default gw: none
netmask: 255.255.255.0
I don't want this one routed at all. It is used for backups, moving files, etc and is called by individual servers using /etc/hosts.
Now problem is that I can't get out and/or in to the box. It appears as though the default gateway on this system is 192.168.2.254. I set up the network via the gui and it appeared to be working, but alas it is not. It looks like things are only talking via the 192.168.2.X network, and that is not what I want...and from the outside world, nothing at all is talking to it.
Below is my ifconfig -a and my netstat -rn
Please help!

Ok...I did the following:
route add default gw 192.168.1.1 eth1
route delete default gw 192.168.2.254 eth2
I am able to get out to the outside world and it seems to work fine, but just curious:
1. How do I keep this from reverting again? (I could put this in my own script, but would rather not hack it, but do it right)
2. Are my routing tables below correct now (it works I understand, but want to ensure it is done correctly).
3. What is this route for (in the below table) and is it needed?
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth2
4. Since i'm relying on /etc/hosts files for the systems on the 192.168.2.X interface should there even be a route for this subnet?
updated routing table:

J6480 wireless and network help please!

I have an officejet J6480 that has an error in printing system when printing wireless. Everything is configured correctly and my printer reads the router and connects. If this problem cannot be fixed, can i use an ethernet connection directly from printer to router and get it to work. I tried this but also got a failure to print message. Please help asap! Thank you

hello,
first, cancel the print jobs
then try to restart the print spooler of the computer (click start>run... then type services.msc)
look for print spooler in the list
right click on the print spooler and click restart
if that doesnt work, then do a partial reset on the printer
unplug the power cord from the back of the printer without pressing the on button
press and hold # and 3 and wait for 10 seconds
plug the power cord back
wait for the printer screen to lit up then release the # and 3
try to ping the printer
try to print a test page again
keep me informed..

Mail and password: Help please!!!

I have changed my password and on my iPhone and iPad there is no problem. However, on my iMac, 10.8.2 every time I put the computer to sleep and then wake it up again Mail tells me to verify my password. I press OK but it refuses to accept and I am forced to go to System Preferences, then mail where I press OK for the same password and the whole thing then works.
In Yahoo it works perfectly!
What is happening in Mail. I have deleted the account in preferences and set it up again but all to no avail.
Help please!!!

You might try the following steps:
Restart the device by holding down the on/off button until the power down slider appears.
Try entering your password in another location (i.e. when you are using a different wifi network)
Reset all settings (settings > general > reset), this resets some of your settings to factory default. It’s not a complete removal of settings. It removes all of your preferences for Wi-Fi, Bluetooth, Do No Disturb, Notifications, General, Sounds, Brightness & Wallpaper and Privacy. It does not remove any of your data.
Try signing out of iCloud and back in (only if find my phone is disabled)
If this doesn’t help your best option may be to contact Apple ID Support, upon speaking to an operator you should explain that your problem is related to your Apple ID, this way you will not be charged for assistance, even if you don’t have an AppleCare plan.

Analog interface between voice gateway and pbx system, please suggest too

Hi
Im a fresh in telephony and voip technology. I didnt find information about design analog interface between voice gateway and pbx system such as fxo-to-fxo, fxo-to-fxs, fxs-to-fxs, fxo-to-e&m, fxs-to-e&m, or e&m-to-e&m. Could you please suggest any resource for me?
Ps. my networks have 1 HQ and 2 branch offices connect to the HQ.
Thanks,
Nitass

Hello,
you can find lots of info about analog voice interfaces here:
http://www.cisco.com/en/US/tech/tk652/tk653/tk754/tech_protocol_home.html
I've found this particular document very useful when trying to understand how telephone signaling works. This applies to any telephone system where interfacing to analog phones or the PSTN is involved.

Dynamic Routing Gateway and ASA

Greetings,
We have a requirement to configure a multisite gateway and have run into an issue. According to http://msdn.microsoft.com/en-us/library/azure/dn133793.aspx, dynamic routing gateways are not supported on the ASA platform. Does this simply mean that MS does
not support this configuration or that this configuration is not possible? I cannot negotiate an ikev2 proposal with a dynamic gateway so I fear that it isn't possible.
Has anyone here made this work?
Thanks in advance.

Hello
In the link you provided, the combination of ASA with dynamic routing says it is not compatible (it does not say not supported).
From that I understand that it will not work.
We have tried a few Juniper combinations in the past with static and dynamic routing that were not on the list you mention - only to find out that they indeed did not work.
My recommendation is to stick to the supported setup.

JSP and Servlet - help please

Hello,
I am making this feedback for fun and a bit of learning too. I have an INDEX.JSP page, where the user selects the very first option. Depending upon the selected option he is moved another page PRODUCTFEEDBACK.JSP (so far I have completed this). Here as usual there are many fields to be filled in. As a spams protection i have done this;
I have a AdditionClass, which is a seperate class where two number are generated at random. This numbers are called by PRODUCTFEEDBACK.JSP. The user is then asked to perform the addition. The completed form is then sent to ProductFeedback servlet.
When I compile my PRODUCTFEEDBACK.JSP I get this error. Can you please tell whats wrong?

After effects and photoshop ,,,help please

hi all
can anybody help please.
ive been making a short film with my son and putting some basic effects in, just for a laugh.
i noticed an effect on ADOBE TV that was done by Gareth Edwards in his movie MONSTERS which i thought would be good to try out in my film but i carnt get it right,,
here is the link to that effect... http://tv.adobe.com/watch/customer-stories-video-film-and-audio/monsters/
its the effect where he changes the menu board in a cafe to one of his infected area signs, he allso changes a few other signs.
in the video he say that he exports a still frame from after effects into photoshop and puts on his image {with a few tweaks her and there}, when hes got it ok in photoshop ,it some how updates in after effects??
can any please help ,thank you

It's a simplified explanation of the process. He left out explanations of motion tracking and perspective matching that were most certainly required for the shot being discussed.
If you are doing the same process to a static, locked off shot, with no foreground objects passing in front of your sign, it would be very possible to create a single frame in Photoshop and just layer it over your scene in AE. But once the camera moves, you will need to understand Motion Tracking. If objects pass in front of the replaced component, you will need to understand Masking.

I can't retrieve usm and vacm tables from router cisco 2800. Help please!!

Hi, I'm doing some tests in a router cisco 2800 using snmp in versions 2c and 3. I configured views and communities for version 2c and user, groups and views for version3; I suppose that the vacm and usm parameters involved in the groups, views are stored internally in usm, vacm tables. I wanted to check if the parameters I configured were inside the tables, but when I tried to retrieve all those values through get table or get next commands, I obtained the answer "end of mib view" in the application I'm using (SNMP J MANAGER) and also in wireshark where the requests are sent but the responses contain the OIDs belonging to the tables but with the value end of mib view.
I know for experience doing the tests, that "end of mib view" is obtained in a response when you try to request a OID that is outside of the view being used by a community. But the last thing I did was create a community related to a view with access to internet included. Later, I used that community (comlectura) in version 2c to retrieve those values of usmtable (1.3.6.1.6.3.15.1.2.2 ) and vacmtable (inside of 1.3.6.1.6.3.16.1) and nothing.
These are some commands I configured in the router:
snmp-server group readonly v3 auth read readview
snmp-server group writeonly v3 auth write writeview
snmp-server view readview internet included
snmp-server view writeview internet included
snmp-server view viewcomlectura mib-2 included
snmp-server view viewcomlectura2 system included
snmp-server community comlectura view readview RO
snmp-server community comlectura2 view viewcomlectura2 RO
snmp-server trap-source FastEthernet0/1
I think the cause of this error perhaps is because these tables don't exist in the CISCO MIB, but I don't thinks cisco devices ONLY have cisco mibs (
1.3.6.1.4.1.9) inside of them, because I can make request with OIDs of mib-2 branches. Anyway, please someone that can guide me in this problem. Thanks in advance.

You cannot use Mavericks. Ask a friend who still runs windows or any Mac OS except Mavericks to bring their laptop and help you out.
Or plug in a USB drive for instance and create a bootable version of any previous version of OSX since 10.5.x -10.8 all of which will work fine.
Or dual boot to windows where the latest airport utility is still 5.6

2nd MBP has messed up my home network--help please

I have a linksys wireless router. I have a MBP 1.83 gz and my MBP 2.2 GZ just arrived today. I turned them both on, both will get onto my wireless network (which is WEP protected) and then after two or three minutes neither computer can go online. Instead of showing a full strenght airport icon (which is normally shown) it shows one bar missing on both computers' airport icon. If I reset the router, I can get on one computer and be online, but as soon as I add the other computer, then I am unable to surf.
I also noticed that if I restart my new MBP I have to restart the router to be able to go on line.
I imagine there is some setting in the router causing this, but my knowledge is very limted. Any suggestions or resources would be greatly appreciated. Thank you in advance and I will be sure to mark your reply as helpful.
Owen Pillion

My wireless router is set up as Automatic Configuration DHCP.
Each computer works fine without the other on. If both are on, my original one works, but the new one cannot get on line.
I do not know how to get the ip configurations of my mac (I wish I did--I dont even know what that is). And I do not know how to see if both are using the same ip address or how to tell the computers to use different ones.
I know that my wireless network has been working fine. I have even used a PC notebook, been able to enter the WEP password, and surf with the MBP on. But with two MBPs--No surfing happening.

Belkin Router Firewall Settings - Need Help Please

Hi
I'm new to Apple and love the machine, but I am having a problem with the firewall on my router. Let me explain the setup, then the problem...
I have the following in my home network:
1 hp desktop running Windows XP Media Center Edition, SP3 (Professional)
1 Belkin wired / wireless router
1 Canon Pixma MP500 Printer set for Sharing (Connected to hp desktop through USB)
1 iMac 20" running Leopard OS
The hp desktop and the iMac are both hardwired to the router. The router's security settings are as follows:
Will NOT broadcast the SSID
Mac Filtering is ENABLED (iMac MAC address is included in list of allowed connections)
WPA-PSK Security ENABLED
Wireless connectivity is ENABLED (For Wii, PSP, and Xbox 360)
Now the problem...
Everything on the network works beautifully, except the iMac. It will not allow iChat services, will not allow sharing of the desktop with other iChat members. It does, however, connect to the internet, but will not access the hp shared folders or printer. When I attempt to even add the printer, the printer does not even show up. I DO have Bonjour installed on the hp, but when I run Bonjour, I get a message that reads something like, "There are no Bonjour enabled printers available."
I know it is the firewall built into the Belkin router because I placed the iMac into the Demilitarized Zone, and everything started working as expected. For those of you not familiar with DMZ on the router, it basically allows you to pick an IP address to place outside of the firewall, so you can keep the router firewall enabled, but you can choose an IP address (i.e., a computer) that is not behind the firewall.
After placing the iMac in the DMZ, I went to add the shared printer on iMac. Not only did it show up immediately and give me the ability to add it and print to it, but I could also browse shared folders on my hp. I was also able to connect to a friend on iChat, and we were able to share each other's desktops.
Before placing the iMac in the DMZ, I opened a couple of ports (I don't recall which ones at the moment), and I was able to get iChat AV to work properly, but could not get the shared desktop feature to work. I believe if I had a comprehensive list of ports to enable, I could get this issue resolved, but I can't seem to find such a list anywhere on Apple's web site (or any other web site for that matter). Do any of you have such a list of ports??
I can provide more information if needed, but any help on this matter would be greatly appreciated.
Thanks a lot in advance for your help.

Thank you, Larry.
I found a soft copy of the Belkin router's setup instructions on-line. I am going to enable the UPnP feature, as the manual indicates that it is necessary to have this feature enabled to do the things I want to do. The manual also indicates that the router ships with this feature disabled by default. I have not had a need to enable the feature when I had two PCs, so hopefully this will solve the problem.
In either case, thanks for directing me to the common ports. If enabling the UPnP feature does not work, at least I can see which ports I need to enable.
