SSH: How to Display user last successful login

[srikantha]

Hi All,

I am using SSH - OpenSSH_3.6.1p2, SSH protocols 1.5/2.0, OpenSSL 0x0090701f.

I have a requirement that when ever any user login to the system, User has to get last successful login information. Right now only root user able to show this message.

I am expecting following message for all the users...

$ login: testuser
$ password:
Last login: Fri Nov 21 08:40:09 2006 from 123.345.432.94

I have modify /etc/pam.d/sshd and /etc/pam.d/login files and added following line in those files

session optional pam_lastlog.so

After that SSH has been restarted still i am unable to see the last successful login information for other users.

I don't know where problem with SSH configuration or SSH version not support this feature?

Any pointers can be helpfully for me.....

Sri

Hi Skiboy....

By using "lastlog -u <username>" command, user come to no about the last successful login information.... But I required this information automatically after user login to the system...The means after enter the password for the given user.

I can only think of doing this in the .bashrc file in the home directory of each user. You might be able to do it in the /etc/profile but I'm not sure.
The following is what you would add to the end of the.bashrc file in the home directory.

# last login
num=0
last | grep $USER | head -2|while read line
do
((num=num+1))
if [ $num -eq 2 ] ; then
echo $line
fi
done

Thanks Skiboy....

Profile modification is working.... However is there anyway to use pam_lastlog.so in PAM.D configuration.

Not really sure what you are asking.
"last" and "lastlogin" get theinfo from PAM.
