SSH issue

**purusrhce** · 03-28-2009

Hi,

I am facing a problem while ssh to remote server.

puru@server1.test.com's password: (When i entered password am getting this error)

Read from remote host server1.test.com: Connection reset by peer
Connection to server1.test.com closed.

Then i tried to su:-

[guna@server1 opt]$ su puru
Password:
su: cannot set user id: Resource temporarily unavailable.

Please help its quiet urgent for me...............

Does the puru user exist in /etc/passwd?

Can you su to any other users (ie, su guna, when logged in as guna)?

Can you 'su puru' from the root account (if you have access)

/var/log/secure.log may have information about the failure to log in as puru over ssh, but you will need to be root to read it.

can you connect with other users . root ; ?
if not
please check if your server configured for hostbased authentification and try to make in ssh config . alllow from all

Dear All,

Thanks for your valuable reply's. I could able to su from "root" to others users but not to puru user. Is there any process limitations? If yes how to increase the process limitations for a particular user.........

Thanks in Advance,

This sounds to me like either the puru user isn't configured, or is configured incorrectly.

Check the entry for puru in /etc/passwd to see if it is the same as other users, on the server you are trying to connect to.

The user was using this account without any problem for last 2 years, all of a sudden he is getting this error. When i searched via google it says something about process limitation & needs to update /etc/security/limits.conf. When i checked in other machines all the values are same. Any help?

Have you checked faillog ?

**purusrhce** · 03-31-2009

Yes i ran this command

"faillog -u -r puru" it ran without errors

Is the puru user over their quota?

How big is their home directory?

Code:

du -sh /home/puru

Can you run:

Code:

quota -u puru
