Overlook in Linux

I've inherited a linux server which looks after email, web cache, internet access and firewall. It had Overlook running on it to access emails from outside the school. However it is now not working. I have no experience in Linux.

Is there a way to check if this is running? What would be the best course of troubleshooting?

Thanks

what distribution of Linux does it host? Services' management differs from Debian to Red Hat

can you post the output of "ls /etc/init.d/" and of "chkconfig --list" ?

you need to find out what the service name of that programm ( overlook)

example , if you are trying to find if sendmail service is running or not you  can check few away

1. ps command , which will show you all running process on the system

ps aux | grep sendmail

it will show you some line which show the sendmail.

2. another one is lsof command if its tcp base service
 lsof -iTCP | grep sendmail

3. check the top command to see if the service is running or not


also as aj_ja_nai said, check chkconfig --list to see if that service is configured to run in level 3 and 5
you can do
chkconfig --list | grep service name

at the prompt root@proxy:/home/a#, I typed ls and got the following in red:
overlook.3.1.tgz

Any ideas what that means?

can you not restart overlook service ??

ai_ja_naiCommented:
I see it's Debian Linux. Run  aptitude install chkconfig.
Also, can you post the output of

ps aux

?

Again have no experience with Linux, how do I find if outlook service is still there to be restarted? How do I restart it.
0
fosiul01Commented:
what about this output

chkconfig --list | grep Overlook

and
ps aux | grep -v grep | Overlook



You need to find out what is the name for Overlook service name, other wise i would not be able to help. beause i never used overlook

He doesn't have chkconfig installed. He has to run

aptitude install chkconfig

to install it

nathankaaAuthor Commented:
I didn't install it, as I said I've inherited it with it installed. For some reason it is now not working.

The main reason it is on there is so that staff can read their emails from outside of school by entering the http://staticipaddress/overlook. Aparently it is an offshoot of SquirilMail. Could I use something else to access emails from outside of school such as SquirlMail?

Thanks people! Even though I didn't find the solution for Overlook, the solution for an alternative was great.

I've also learnt a few basics about linux and can actually find my way around a little bit!!
