Hi, since an unattend shutdown of our server, our B&R can't established connection to our (only) linux vm.
Of course this stuff worked before.
When i tried to connect through ssh for the first time after the shutdown, it says that fingerprint key of the host changed. I bassicaly remove the old fingerprint in my local known-hosts file.
- I checked sshd logs in the timeframe i tried to login through B&R console and this shows :
sshd[10137]: Unable to negotiate with 192.168.0.216 port 52062: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1 [preauth]
sshd[10139]: Unable to negotiate with 192.168.0.216 port 52063: no matching host key type found. Their offer: ssh-rsa,ssh-dss [preauth]
- I tried to allow diffie-hellman-group1-sha1 and ssh-rsa in ssh_config file of my server. But it doesn't change anything. ❌
- I tried with different user, it doesn't change anything. ❌
- I reinstall ssh-server, it doesn't change anything. ❌
- On B&R console i removed and add host in backup job, it doesn't change anything. ❌
- From the bakcup server i tried to connect to linux host with putty, it doesn't work with the B&R putty's version. ❌ BUT with the latest version it works and ask me to accept the fingerprint. ✅
After all this tests I'm wondering, there's a known-hosts file likes for veeam B&R ? How can i clean cache connection between them ?
We run:
-
B&R in 9.5u3 (need to upgrade)
-
Hypervisor: Hyper-V 2012
-
Linux host : Ubuntu 22.04
-
Linux user : admin user into sudoers file
I would appreciate any help.
