Since i've installed telnet on my linux mandrake machine its worked perfectly. But when i went to try to log in today i found that it was refusing connections. So i did the normal, checked the firewall, made sure it was still installed as a server and everything, but to no luck. When i went to my deamons/services menu to make sure it was running, it wasn't there. Everything else that should be just not my telnet server. So i figured mabye the install was currupt or something so i went and uninstalled it, and reinstalled it. Install went well, no problems occured, go back to services menu, and still no telnet. Has anybody ever expirenced this type of problem before and if so how was it fixed.

I use telnet because it is convient and comes default with windows, I would use ssh but i am unable to install it on my school computers with out going through the effort of disabling their security, and i just don't have time to do that to each one of their computers. I realize that it is a big security hole, and don't care all that much... If ssh came standard on windows i'd use it instead. Also it is a telnet server, not a client. And it has worked for about a year till i tryed to log in via that today, which it didn't work.

Finally an intellegent responce from someone who actually read the post, i'll give those things a try, and get back to ya. And yes, i do realize that telnet is like going outside and yelling my passworld to the world, and at the moment convience is more important then security, eventually i'm sure i'll make the switch but am well, to lazy at the current time.

Some lil info (future refrence etc, tcp wrappers) Probably TCP Wrappers and the old "double reverse lookup problem." Try adding an entry in /etc/hosts to refer back to your client(s) and make sure that your /etc/nsswitch.conf and /etc/hosts.conf are configured to honor "files" over DNS and NIS. On Linux systems the /etc/inetd.conf is usually configured to run most programs under an access control and logging utility called "TCP Wrappers" (/usr/sbin/tcpd). That utility refers to a couple of configuration files (/etc/hosts.allow, and /etc/hosts.deny) and it does some "paranoid" consistency checking to try and ensure that the client "is who he claims to be." The specifics of this paranoid checking are referred to as a "double reverse DNS lookup." Linux uses a modular name services resolution system. Newer versions of Linux use the /etc/nsswitch.conf files to control the list of name services that are used for each name space (users/accounts, groups, hosts and networks, services, mail aliases, file server maps, etc). In most cases you wouldn't have to modify the nsswitch.conf to make it look at the /etc/hosts file. In other cases you might other sites of refrence Perl's NET::Telnet and NET::Telnet::CISCO modules may have what you're looking for. Check www.cpan.org. (please watch what neg [censored] you say)

Cheers good fellows, I got it up and running again. Thank you for the info specially on the TCP Wrappers, i'll have to go do some research to further the extent of my knowlege on em, but i got a few tests done using the hosts.deny and my windows machine, and everything seems to be working
