That is a critical error, migration was stopped.

where can I get some more information about error?

Thanks

 

[metalalisa]

Anybody, guys?

EOF during negotiation

This means that the server is dropping the connection. I'd suggest you check ssh connection between servers.

 

[metalalisa]

Connection via port 22 as root is successful between servers in both directions

 

[metalalisa]

Migrator even creates folder in /tmp/panel_migrator/migration_agent

 

[IgorG]

Do you have any specific options in .bashrc ?

 

[metalalisa]

# cat /root/.bashrc
alias htr='apachectl -k graceful'
alias freemem='/root/install/smem/smem  -u -t -k'

 

[metalalisa]

What should I check now?

 

[IgorG]

Do you have more detail from migration logs?

 

[metalalisa]

Of course. And I hope you tell me where I can get them.

Yes, I've already found debug.log

There are lines

Should I send the whole file as private message?

 

[Alexey Baturin]

Please send the whole debug.log to me via private conversation here.

 

[metalalisa]

Problem solved.

On my source server

# tail /etc/ssh/sshd_config
Subsystem       sftp    /usr/libexec/openssh/sftp-server

where /usr/libexec/openssh/sftp-server does not exist.

Thanks for help!
