SSH not working after RME upgrade to 4.0.6

Hi all

After upgrading RME to 4.0.6 nothing works for SSH devices Archive,Netconfig). I get "RME_CDL1031:Transport session to device failed Could not detect protocols running on the device TELNET: Failed to establish TELNET connection to 10.69.xx.x ".

This was working fine before upgrade from 4.0.5, also the credentials report shows "Failed to connect". I know the credentials are ok since i enabled Telnet in one of the routers to prove credentials OK.

I also tried on a testserver, everything is fine even after CS upgrade to 3.0.6 but after applying RME 4.0.6 I get the same symptom.

Using sniffer i can se the routers responding with "SSH version 1.5" but then it fails.

anyone got a brilliant idea ?

Re: SSH not working after RME upgrade to 4.0.6

My patch is available, and does work. If all your devices fail after applying it, the patch must have been corrupted in transit, or was installed incorrectly. That said, the RME 4.0.6 update was just re-posted with my patch. So if you re-download and install RME 4.0.6, the problem will be fixed.

Hi Mats,

Enable SSH in RME -> Admin -> configMgmt ->Transport settings -> Archive mgmt/netconfig.

Hi

Thanks, but as I said it worked fine in 4.0.5 and I checked the Transport settings twice. I can tell by sniffer that RME (or credential verification) is trying SSH but then fails.

Re: SSH not working after RME upgrade to 4.0.6

This error indicates a problem with the data returned from the TCP connection to port 22. You should enable ArchiveMgmt Service debugging under RME > Admin > System Preferences > Loglevel Settings, run a new archive sync operation, then check the dcmaservice.log for errors.

Of course, I'm assuming that before you upgraded to RME 4.0.6, you applied the Common Services 3.0.6 update. If not, you will need to apply the CS 3.0.6 update, then re-apply the RME 4.0.6 update.

Re: SSH not working after RME upgrade to 4.0.6

FYI, I tested this locally after upgrading to CS 3.0.6 and RME 4.0.6, and I am not seeing any problems with SSH.

Hi

Thanks for responding quickly.

Yes i have confirmed CS 3.0.6 is ok installed.

Attached output in dcmaservice log after enabling debug. From what I can tell it first says "SSH is running on /10.69.77.1" and then shortly after a FATAL "could not detect protocols running on the device". I have to admit it is not my best skill to read theese debugs, please have a look to see if you can pinpoint the problem.

Btw

I reinstalled RME 4.0.5 on the testserver and synched config on the same 10.69.77.1 router without problem.

Re: SSH not working after RME upgrade to 4.0.6

Looks like your installation is bad, or you have re-applied some old patches after installing RME 4.0.6. The NMSROOT/MDC/tomcat/webapps/rme/WEB-INF/classes/com/cisco/nm/rmeng/util/rmedaa/RMEDeviceContext.class looks bad. The line numbers in your log do not line up with the actual code, but they do on my server.

You might try reinstalling the RME 4.0.6 update. The MD5 checksum for the file above should be:

4d04e1ad1e29a206899c0853857b2fb4 RMEDeviceContext.class

Re: SSH not working after RME upgrade to 4.0.6

Hi

I reinstalled 4.0.6 on the testserver (Windows 2003, as well as Prod server) no additional patches on the testserver only CS and RME. sych failed again.

The RMEDeviceContext.class got a different checksum on my system, but is the same on both servers as well as timestamp and bytesize.

But the culprit must be RMEDeviceContext.class, as I did an "ugly" test on the testserver and swaped it to 4.0.5 version and restarted, archivesynch is ok after that.

Fileinfo:

ab9c8b46e27a87719d01f66b8343f9da 2007-11-15 11:33 22 009 RMEDeviceContext.class

any idea ?

Re: SSH not working after RME upgrade to 4.0.6

I have a strong feeling the Windows RME 4.0.6 is broken. I assume you're testing on Windows?

New Member

Re: SSH not working after RME upgrade to 4.0.6

Yes, and the "live one" is w2003 also.

It seems like using version 4.0.5 file is a temporary workaround to this problem. I have not noticed any other probs with RME yet, been focusing on this...

pls let me know what happens.

Re: SSH not working after RME upgrade to 4.0.6

I have confirmed the Windows update is bad. If you download the Solaris update, extract it, you will find an RMEDeviceContext.class. That is a good version. Simply replace your version with that one, restart dmgtd, and you'll be fine.

Re: SSH not working after RME upgrade to 4.0.6

Hi

I get the same error with the solaris one on both servers, I verified checksum on the solaris file and that is the same as yours.

I suppose i can use v 4.0.5 until a fix is available, to avoid reinstalling RME on the Prod server.

I see the problem. Please open a TAC service request, and have your engineer contact me for the patch.

I will do that. Thanks a lot for pointing out the problem so fast.

Was a patch made available for this problem or was a bugID assigned to it?

New Member

Re: SSH not working after RME upgrade to 4.0.6

Hi

Not yet, I got a new file today from TAC, tried it, and all RME jobs failed with pending device. I suppose a good one will be available soon.

Re: SSH not working after RME upgrade to 4.0.6

I downloaded the RME update and re-installed. The problems we had with SSH to most devices did resolve after the re-installation.

Thank you.
