I want to test email from my local machine, and i am using MAMP. I found couple of article online explaining this. I need go and edit /etc/postfix/main.cf file and add a line.

relayhost = smtp.example.com

Article says,
smtp.example.com is an example smtp server. It's different depending on your internet provider. I'm at Harvard now, so mine is: smtp.fas.harvard.edu.

What would be our smtp server?

Thanks, Noushad

I need to create shell accounts, with limited background processes, and applying some restrictions to the users. also I would like to add a ~/www for hosting that clients webpage.

I've done half of what i've mentioned some time back  But it didnt work out the way I wanted it to be,... I had to enable each service separately and doing this for a number of users was hectic. is there a utility of some sort that would automate the whole process....shell/http/ftp and so on.

here are some of my requirements:

1) Authentication password + private/public rsa key
2)  chroot directory
3) all user accounts go under a custom folder /uaelug/username1 /uaelug/username2
4) sftp enabled so I will not require an ftp server
5) http access under ~/username1/www (apache)
6) user logging + anything that would enhance security
7) limit ul/dl  without the reliance  on a proxy server (I have a proxy server, but this machine wont be behind it)

Thank You,
Tux

I would like to know your thoughts on this.

I just needed a oneliner which reminded me in last meetup.

If I remember correct Zak wanted to know how you can find which process is underlying to a service which is open on your system.

Simple example for port 80.

xaitax@w00t:~# ps auxf | grep $(fuser -n tcp 80)
80/tcp:
www-data 12274  0.0  0.1   5868  1832 ?        S    04:39   0:00 /usr/sbin/lighttpd -f /etc/lighttpd/lighttpd.conf

Explanation:
`ps auxf` gives you all running processes.
`fuser -n tcp 80` will show you the process id of the process bound to port 80.
Both combined will give you the above.
