Putty:server unexpectedly closed network connection
 

I putty. when I try access to another machine I receive the message of putty Why?
When I do: ssh -X 192.168.1.4 the output is: So, the problem maybe is in ssh.

Hi,

Please check whether there is any firewall using the iptables -L ?
Check whether the SSH server configurations had any restrictive users to login ?

Regards
Good Luck

FC16 X Putty:server unexpectedly closed network connection
 

I putty 0.62. when I try access to another machine with FC16, I receive the message of putty server unexpectedly closed network connection

solution: clear option in putty program: Category -> Connection -> SSH -> Auth -> GSSAPI -> Attempt GSSAPI authentication (SSH-2 only)

Connect by telnet if possible, And check if sshd service is UP..

Oho I missed the complete threads.. your sshd service is up..
hmm seems like your root user is blocked.. interesting..
However If its possible then use telnet and check the /etc/hosts.allow and /etc/hosts.deny
if it contains your IP

And also check these following files
/var/log/secure, /var/log/auth.log, /etc/ssh/sshd_config and /etc/pam.d/ssh or /etc/pam.d/sshd or /etc/security/access.conf files

I had a similar issue until I set the Keep Alive in the Putty connection to something other then 0, it seemed to work best around 30 seconds.

Hey people, thanks, but I was not clear, I posted a problem he was having and with the resolution just below this, and I'm new to the forum ... grateful, I will replicate the question along with the solution:
