I have made an update to CentOS5.7 and since then I can't access by SSH to the machine. I have disable the Firewall and I have the "sshd" service active.

I got the following when I do this from the local machine(localhost):

$ ssh andre@
ssh: connect to host port 22: Connection refused

$ ssh andre@
ssh: Temporary failure in name resolution

Can someone give me a clue on how to solve this problem?

check, if the machine really runs sshd on port 22:

# netstat -4nl | grep ":22"

and if the machine really has the ip

# ifconfig

and if the machine can be pinged from where you want to access it:

# ping

your 2nd command is faulty because it means `connect to the machine with the name '' (and since your dns-resolver is not able to map that name to a valid ip you got 'temporary failure in name resolution'). the flag to set the port is '-p'.
