TCP/IP command in stand alone


hi,

i am currently using redhat 7.3. my problem is, when i want to practice some commands like telnet, talk, ftp .... i try to connect to the localhost (which is my PC), but it wont work. then is there any extra configuration that could enable me to practice all of this on stand alone system?

All those you mentioned are clients. Clients need a server to connect to. If you use them on localhost then you have to have a server running on localhost.

yeah, you are right. it took a while for me to figure out your question. finally i realised that my mistake is i did not check my system. actually those erver did not run on my system. i thought it is automatically co9nfigered and run because i had selected everything during intallation.

You should be able to get telnet working by typing the following command as root:

chkconfig --levels 345 telnet on

I don't think that there is any configuration needed at this point to connect so you can try:

telnet your.ip.address.here

You should shut telnet off when you are done because leaving it open justs gives attackers another avenue into your system. To shut it off run the 'chckconfig' command as I stated above but change the 'on' to 'off'.

As for FTP there are a couple of different FTP packages you can go with and there are plenty of threads in this forum on how to set them up.

Don't use the talk server because its full of security holes and the its just poorly designed. I would also suggest looking into SSH(Secure SHell) rather then telnet. Telnet is rarely used anymore because everything is sent out in plain text. If you just want to mess around with things and get a feel for telnet then thats no problem but if you want to actually setup a remote login server go with SSH.
