This host was accessible until the system was reboot following the update. Can someone tell me how to fix this?

What is sshy?

 

[VladiBG]

check if the sshd is running on vhost02 and there's no firewall blocking the port 22.

 

[byrnejb]

$ declare -f sshy
sshy ()
{
    ssh -t -Y -o ConnectTimeout=10 "$@"
}

 

[byrnejb]

Good call. It was the timeout value in the function that was the source of the problem. Increased it to 60 and connected.

 

[rmomota]

$ declare -f sshy
sshy ()
{
    ssh -t -Y -o ConnectTimeout=10 "$@"
}

Did you try the ssh without any extra parameters?
