FastSCP - Adding an OpenSUSE 11.2 backup server (SSH issues)

Post by cdadswell » Aug 26, 2010 10:52 am

Hi,

I'm currently attempting to eval Veeam in our vSphere environment.

I have installed a x64 bit Windows 2003 Standard server with all the Veeam x64 bit software. Thus far I have managed to add our VC with no problems.
I then came to add a Linux server and no dice. I get;

"Failed to login to "x.x.x.x" by SSH, port 22, user "root", elevateToRoot False, autoSudo False User authentication failed."

So, I then tried putty, knowing full well it would work. And it did.

So then I chucked Wireshark on to watch the traffic. It appears that the failure occurs when the client is receiving new keys after the diffie-hellman key exchange. With putty you accept the keys the first time you connect. But with Veeam I do not get any such prompt.

Does anyone have any idea how to get this working?

Thanks in advance,
Christian.

Hello Christian,

Could you please clarify if we are talking about Veeam Backup and Replication or Veeam FastSCP tool? In addition, please have a look at this topic which refers to SLES connection issues, should be helpful in troubleshooting your issue as well:

Thanks!

Hi,

Thanks for the response. I'm running up the shortcut for Veeam Backup and FastSCP. I'm then doing an add server from the toolbar.

The Linux machine I'm connecting to is OpenSUSE 11.2. I am able to connect to the same Linux server over putty with no issues.

Here are the logs of the brief conversation;

I have omitted the domain name with x.x.x

I will move this topic to Veeam Backup forums, as this is not related to FastSCP. As regards the error, could you please tell me what is the name for ssh server? I want to insure you're using OpenSsh for establishing the connection.

Re: FastSCP - Adding an OpenSUSE 11.2 backup server (SSH iss

I have looked at this again this morning and connected successfully to a Ubuntu Server running;
OpenSSH_5.5p1 Debian-4ubuntu3, OpenSSL 0.9.8o 01 Jun 2010

When I attempt to connect to an OpenSUSE box running ;
OpenSSH_5.1p1, OpenSSL 0.9.8h 28 May 2008
I still get no connection.

I take it from this that the older version of OpenSSH and/or OpenSSL isn't supported? I have tried to update from the SuSe repos and it stays at the current version.

Christian,

Could you please confirm that you've enabled Password authentication in the sshd configuration file and restarted the service for OpenSuse machine as it is mentioned in the forum link above?

Hi,

Thanks for the info, I checked the Passwordauthentication and it was enabled.

To get this working, I ended up making and compiling OpenSSH and OpenSSL to the latest versions on the OpenSuSe server. Once I did this Veeam connected no problems.

Thanks for your help.
Christian.
