RE: [expert] Can't Access My linux box! R there any experts out
Hi: I have a linux(mandrake) server and its hosts.deny file deny All except localhost and another ip The problem is that I am not able to access this server remotely through telnet from any machine not even from the machine having same ip as mentioned in the host.deny file. Only once I could access it remotely through telnet from machine with ip. Error msg that I get is Remote system refused the connection .. And also I am not able to login through server terminal because the keyboard is not getting connected. when I connect the keyboard, initially three lights of the keyboard(caps, num and scroll lock) blinks for a second and then goes off. I am using this server as gateway, its runing fine other than the fact I am not able get hold of it :) Can anyone help me out ? Have my server been hacked ? Have a look at the xinetd config files (/etc/xinetd.d/* /etc/xinetd.conf). There's a only_from options maybe this is set to.

Thanks Jawad End forwarded message (first, PLEASE try to NOT send html-email! It greatly reduces your chance of being answered (at least by me ;-) ) First, is the telnet daemon running on the server? Second, when you plug the keyboard in, do you do it BEFORE booting or after? Their MAY be a problem with your BIOS or whatever that won't let a keyboard be recognized after booting without one. Third, it would be much wiser to use sshd instead of telnetd (i.e. use ssh to get to the machine instead of telnet). http://www.openssh.org/ (I think) (Plus, it MAY already be on your machine, or their may be RPMs for it - you'll need the sshd (server) software on the server, and ssh client software on the machine you allow in. Hopefully this helps. And at this point I'd reserve judgement on whether you've been hacked or not - its possible, but I doubt it right now... rc Rusty E.

What about hosts.allow? I believe you must add the IP and localhost to this file. And telnet and inetd or xinetd must be running... Salu2, óscar.
