13.04 using ssh command problem

**cosname** · May 29th, 2013

Hi!
When i connecting to the service through ssh using private key, the process works good.

But i also have servers that have connection through password typing (password prompt for selected user).

I use commands like this:

Code:

>ssh username@sitedomain-or-serverip -pPORT
>> ssh_exchange_identification: Connection closed by remote host

And see no result for a long time, like it was frozen. And after 2-5 minutes it gives "Connection closed by remote host" message.

I tried to use

Code:

> telnet sitedomain PORT
>> Trying server.ip...
>> Connected to server.domain.
>> Escape character is '^]'.
>> 220 (vsFTPd 2.2.2)

And seems that servers is working good.
Why average ssh with password prompt authentication does not work`s?

I need urgent help, it is required for my work (mostly i need this for > tail -f 100 filename.log command to fetch error logs)

Thank in advance!

Try running the ssh command with full verbosity, it may give you more clues...

Code:

ssh -vvv user@host

**cosname** · May 29th, 2013

Code:

cosname@cosname:~$ ssh -vvv domain -pPORT
OpenSSH_6.1p1 Debian-4, OpenSSL 1.0.1c 10 May 2012

I also found some solution in:
http://ubuntuforums.org/showthread.p...50#post8789350

Code:

apt-get remove --purge libk5crypto3
apt-get install --reinstall libkrb53

but im afraid to do remove-purge couse of this output:

Code:

cosname@cosname:~$ sudo apt-get remove --purge libk5crypto3

Oh, i`m not good with ssh & ssh-agent with those rsa/dsa/ecdsa encreptions using... So i think i must give some more keys when using ssh for password promt.
Or run some commands before...

Have you tried another port? The port that you are telnetting/sshing to is not a ssh port. Instead, it runs a FTP server called vsFTPd

**cosname** · May 29th, 2013

Omg.... silly me, i mentioned the port that was configured for that server. All is working fine now.

Will remember about vsFTPd. Didn`t payed enough atation to it.

**sandyd** · May 29th, 2013

If you want to see what applications are using a particular port, you can use

Code:

lsof -i :port

If you want to see what ports are open (not taking into effect firewalls such as iptables)

Code:

netstat -l

Thank you, hope that after some time i will get used to unix commands and bash scripts...
