SSH to local hosts

[George Chechakunnil]

Hello Gurus

I was having some issues with HP SIM and i found that if i do a

ssh 127.0.0.1 it fails even when i give the correct password.

Is there any file i need to add the local host entry for ssh?

please help

Hi George,

take a look at /etc/opt/ssh/sshd_config:

If PermitRootLogin is set to no, you have to change it to yes to allow root logins.

Hi george,
try to put a wrong passwd in first time and type the correct passwd in second time.
check whether it is accepting or not?

Hi George,
Please check the file
/etc/opt/ssh/sshd_config

If PermitRootLogin is set to no, you have to change it to yes to allow root logins.

Then Please restart the sshd service.

Thanks & Regards

If it's not the PermitRootLogin directive,
as so apparently suspected by most,
look if you have a DenyUsers definition in your sshd_config, albeit this seems pretty unusual.
After any configuration changes you must send sshd a SIGHUP to make them become effective.

# vi /opt/ssh/etc/sshd_config

# kill -1 $(cat /var/run/sshd.pid)

Could it be you are running a tcp wrapper?

Please, look for error messages from sshd in syslog.log

# grep sshd /var/adm/syslog.log | tail -20

[Ralph Grothe]

For debugging purposes you could start a second sshd instance on any unused port (e.g. check with netstat -an|grep LISTEN|grep ).

Prevent the new instance from detaching from the tty, and send verbose debug output to sterr instead of to syslogd.

e.g.

# /opt/ssh/sbin/sshd -p -Dddde

From a second tty try your root login to localhost but chosen port.

# ssh -p localhost

Watch messages on by 2nd sshd occupied tty.
