Setting up Telnet on Linux

by ariefk In reply to Good man die young

These days ssh are widely used to do remote console session to *nix server. <br />But now, for the shake of knowledge, I'm going to describe how to enable telnet using RedHat. <br />I hope it would be useful, at least for myself. <br /><br />Logging in via Telnet<br /><br />First off, avoid using telnet if at all possible. Telnet sends all of its information "in the clear," meaning that its communication (including passwords) can be easily intercepted. Instead, use the secure SSH protocol. OpenSSH and OpenSSL RPMs are available are available at ftp://ftp.redhat.com for quick, easy, and secure way to remotely connect to your machine.<br />If you must use telnet rather than SSH, you should make sure you have the Telnet server installed by logging in as root and typing the following command:<br />rpm -qa | grep telnet<br />You should see a result with two packages, one of which is telnet-server. If you do not see telnet-server, install it from off of the installation CD-ROM by logging in as root, inserting the CD-ROM (or the first installation CD-ROM in Red Hat Linux 7), and typing the following commands:<br />mount /mnt/cdrom<br />cd /mnt/cdrom/RedHat/RPMS/<br />rpm -ivh telnet-serv*<br />Also, in 6.2 and before, make sure that you have the Telnet service in /etc/inetd.conf activated; <br />(uncommented), then restart the service after any changes by typing:<br />service inetd restart<br />Under 7, you need to check the file /etc/xinetd.d/telnet to be sure Telnet is activated <br />then type:<br />service xinetd restart<br />This will restart the xinetd service and activate any changes you have made.<br />You will also need to edit /etc/hosts.allow and /etc/hosts.deny to make sure that Telnet access is allowed to the machine.<br />

Setting up Telnet on Linux

Good point, from my point of view, in the 'Linux' world, as long as you keep patched, you won't miss the train. I still have a an Oracle database server which runs RH6.2 and runs well upto now.   <br /><br />

Log on to telnet as a 'root'

by ariefk In reply to Good man die young

Telnet as root   <br /><br />Red Hat does not recommend allowing a root user to telnet to a remote machine. There are many reasons for this, not the least of which is the fact that sending raw text root passwords over a network is not a good idea.<br />A better alternative than telnet is ssh, an encrypted version of telnet, which provides a secure connection to remote machines.           <br />If root access is needed remotely, a user should login to the local machine as a normal user and then su to root before telnetting to the remote machine.<br />To allow a root user to telnet into a machine, login as root and add the following lines to the /etc/securetty file:<br />pts/0<br />pts/1<br />pts/2
