Sshd

[Joaogl]

Hello,


I cant config my ssh but i really need it...


Some one can show me how to to it?

[Irithori]

You need it to do what?
Interactive shell login?

At least your operating systems and versions as well as the network layout would be needed background information to help you.

[Joaogl]

when i try to connect to the linux via Putty it says: Network error: Connection refused....

So something is wrong

[Irithori]

Can you check via a local login, if

• the sshd daemon is running

  ps auwx|grep ssh

• which port it is listening on

  netstat -tunlp |grep ssh

• a firewall is blocking

  iptables -Ln

[Joaogl]

[root@localhost joaogl]# ps auwx|grep ssh
root      7214  0.0  0.0   8472   960 ?        Ss   15:59   0:00 /usr/sbin/sshd
root      8775  0.0  0.0   4328   764 pts/0    S+   22:09   0:00 grep ssh
[root@localhost joaogl]# netstat -tunlp |grep ssh
tcp        0      0 0.0.0.0:31222               0.0.0.0:*                   LISTEN      7214/sshd           
[root@localhost joaogl]# iptables -Ln
iptables: No chain/target/match by that name.
[root@localhost joaogl]#

What that means?

[Irithori]

That means, that I forgot to give a complete firewall command

But the netstat shows, that you run ssh on the non-standard port 31222.
So you need to tell the client -in your case putty- to connect to this port on the server.

[Joaogl]

Know it says

Server unexpectedly close networ connection

[Joaogl]

Why this is happing?

[Irithori]

Maybe a firewall is blocking the connection:

iptables -L -n

Or the ssh daemon is misconfigured.
For this, a log of the connection attempt would be usefull.
