Shell Programming and Scripting

Hi,

I need to shell script if anyone logins Via ssh to my box a mail authentication should be received to my email id.

Thank you
Siva

So you want to be emailed whenever someone logs in? One way that may work is to add a line to /etc/bashrc (if that's the default shell for all users). You may be able to add something like:

Code:

mail -s "$USER has logged in." email@host.tld < /dev/null

I haven't tried this but maybe someone who has can chime in.

Not sure what OS you're using but if you have a logcheck and a logcheck.ignore file you could set it up so that user logins with login id's and system ip/dns name gets logged and emailed as a system event log file using cron. That would give you multiple records in a single email ever hour.

I've seen hundreds of ssh entries in a day to my servers. We have server logs emailed every hour using cron, keeps the emails from piling up so bad.
