Vcenter Backup failed

Veeam Logoby Reiner63 » Tue Feb 03, 2015 9:44 pm

After upgrading from V7 to V8 (incl. newest Patch) Vcenter Backup Fails.
Reason:

##Checking Linux credentials##
##Testing SSH credentials for: root Error: The negotiation of encryption algorithm is failed##

Vcenter is a very new Appliance as provided by VMWARE without modifications.

And yes - credentials are correct.

Other VM´s (WIN) without Problems.

KB 1890 doesn´t help.

Reiner,
as the message says, it's not a credential problem but related to SSH configuration on the VCSA. I don't have a vCenter appliance to test, but probably it has something to do with the configuration of ssh daemon.

Hello Luca,

thank you for your reply.

But this Installation of VCSA is identically with many others.

I can´t believe, that ther is anything different in SSH.

Latest Backup fails with: 'Unable to establish SSH Connection with any Connection point'

It seems to me it could be a TCP Problem (Firewall?).

Port 22 and 433 are open on Backup-Server.

Did it work with v7 or it started to throw this error after you've upgraded to v8?

It worked with V7 over months perfectly.

First Backup after upgrading failed because missing credentials for Vcenter.

Since giving this credentials to V8 i can´t get a Connection to Vcenter.

What did our support engineer say after reviewing your log files? Cannot see it in the ticket, since it is closed for some reason.

He told me to Switch off indexing of Vcenter, because it´s not necessary.

I think i will reopen the case!

Reiner,
in general please do not accept solutions like disabling features or similar, otherwise the issue will stay open or will surface again in the future, if not with you maybe with another customer. Please ask support to work again on the issue. VCSA is a linux VM, so indexing should work.

Sebastijan, what Veeam B&R version are you at (including build number)? Have you contacted support already?

No i did not. We use Veeam B&R 8.0.0.2021.
And there is one more error with backup up vCSA ....
"6.5.2015 21:24:58 :: Failed to create indexer. Details: Unable to establish SSH connection with any connection point."

Looks similar to the OP's issue, however I cannot see any resolution in his case, so please contact support with debug logs for investigation.

I think this is the solution ...


login to vCSA server with ssh and change timeout for shell:
shell.set --enabled true --timeout 2147483647 (68 years ... max value)

replace login shell (temporary):
chsh -s /bin/bash

for change back (if u want):
chsh -s /bin/appliancesh
