All good suggestions, but here's something online that's a little more thorough. Of course, security is something that never seems to be done, so my link is no more all-encompassing than the others. This link comes from cert.org, the kinda central hub of computer security:
Bastille is written by one of the contributors to securityfocus.com, another great security website. The program asks you a bunch of questions (offering great explainations about what it wants to do) and hardens your system a little.
i want to install document manager called anyportal(php) in a linux box. Kindly advise how do i go about it like the procedure which will i suppose will need installng php in my linux box, please help me
If you were using a current/recent redhat version you would install the 'telnet-server' rpm (not only 'telnet' - thats just the client s/w). After that you have to set it as not disabled under the xinetd daemon (as root) :
/sbin/chkconfig telnet on
Then you may have to configure the linux firewall (all depends on version) to allow telnet through on port 23. Again, if it were redhat 7.x, you would do (as root) the command '/usr/sbin/lokkit' and either allow telnet or set your lan interface as 'trusted'.
Once thats been done you should be able to telnet into the linux box from win98. Remember, however, that the security permissions do not allow you to login via telnet as root. You have to login as a regular user and use the 'su' command if you want to do root stuff.
If that doesn't work because you are using another linux give some more details - one of the problems is that there are variations in the way you achieve the same thing between distros so its not always easy giving definitive answers.
