View 1 RepliesI try to install a server based on Ubuntu. It will provide many different services as SMTP, IMAP, Jabber, SVN(via Apache),maybe a groupware and some other web applications.I'm looking for a way of authenticating the same set of users (a user essentially has a username, a domain it is belonging to and some passwords) against all of the services.What is the most flexible and elegant way? I need a method which is not too bloated (mysql or ldap would be okay) and is easily applyable to all those services and all services which maybe will come later.
I've read some documentation about sasl, mysql-authentication, ldap-authentication, pam, cyrus, apache, ... and i'm somewhat confused now about the proper way.For now I suspect MySQL to be the best method for that, but i'm not sure about the flexibility for embedding it into all the services.

In windows something like this would erase everything. Can the kernal be updated without losing everything? 2) Can you have more than 1 account on mint? (ex: Owner, Billy, Guest...)2.2) ...Can the accounts have different access levels? (ex: Admin vs user)2.3) ...Is it possible for one account to run a program the others don't?

how to do Lempel-Ziv-Welch compression using pen and paper for my algorithms and data structures class. Unfortunately we have only a couple of examples in our book of how it is done. I'd like to practice compressing and decompressing text using it, but I need to find a way to check if I'm right doing it right or wrong.
So I'm looking for some preferably free/open source program which can compress and decompress LZW for Windows or GNU/Linux. Programs without binary distributions are fine too.
I am trying to run open a GUI program on a remote Ubuntu machine using ssh.
I want to open, lets say firefox or skype, on a machine I have connected to via ssh.
But when writing logging in with user2 and writing sudo -u user1 firefox I get an error message saying no display specified.
The machine is turned on and logged in with user1, it just appears that i cant get ubuntu to recognize that there is a GUI available.
On Unix I can call certain programs from everywhere, like sort, pwd or my_custom_script.sh. How can I find out, where on the system my_custom_script.sh really resides?
