Generally we don't write scripts outright for people, but we'll be happy to help you with your script. I would suggest that perl (or language of your choice) or expect are better suited to this task than bash overall.

Also keep in mind pop3/imap are insecure protocols... you really should be using imaps or pop3s instead.

I know they are insecure, but i need only for checking pop3 connection (telnet localhost 110 , then echo username - echo pass), if will give me -ERR or +OK, and send me email if pop3 give -ERR or +OK... theat's all.
I am new in the world of linux, and i like it verry much to work on it :P. 3Mouth
The scrept i want to be in bash, it is simply.

THX.

Does it work? If not, what are the symptoms?

If you can send mail from the command line then you can use something similar in the script.

Have a look at the command line mail clients "mail" and "mailx".

Presuming you want to send mail via a remote mail server you will also need a local mail server to send the locally-created mail to the remote server. This will probably be an SMTP mail server like sendmail or postfix -- or hopefully someone will suggest a simple one!

Better than mail would be mutt or pine also... they're fairly full featured.

Does that do what you wanted -- "When he give -ERR (he can't connect) send me email,"? It looks like it sends some strings to port 110 on hostname; it doesn't look like it does anything if the telnet session doesn't connect.

yes, but i put in cronjob to give me at 10 hours email. I know it not a right way... he give all the information.
now i work on samba, i will focus later on it :P.
i will try with mailx, to send me email if he can "read -u 3;".
