Hello,
How to enable telnet in RHEL 4 ES?ssh is OK.But I just want to try telnet.I searched /etc/xinetd.d/telnet but no such files.please.....help me.

hi,

you first check whether telnet package is installed on ur m/c, by
using rpm -qa | grep telnet*
then edit /etc/xinetd.d/telnet and change disable = no
then you start the daemons by using /etc/init.d/network restart and /etc/init.d/xinetd restart

bye

From my RedHat AS 3 the /etc/xinit.d/telnet looks as follows:

# default: on
# description: The telnet server serves telnet sessions; it uses \
# unencrypted username/password pairs for authentication.
service telnet
{
flags = REUSE
socket_type = stream
wait = no
user = root
server = /usr/sbin/in.telnetd
log_on_failure += USERID
disable = yes
}


You can create this file and as prior poster says change "disable = no"

Also run "iptables" and verify you aren't excluding everything. You might need to open up telnet's port there if you are.

Having said all that I'd strongly suggest you NOT enable telnet. It is a very insecure communication tool. Since ssh is free for Linux/Unix and there is a free openssh for Windows you should be able to make any machine do ssh so do not have to enable telnet.

Thanks to All,Tenet rpm is not installed;solved.

Before you try telnet, please be sure you understand the risks.
There is probably a good reason the rpm is not installed in RHEL 4.

Use SSH intead

Telnet might seem convenient, but you're asking to get hacked.

I understand that telnet is not secure at all
But i need to test it
How to enable telnet on RHEL 5??
Please help

Please don't post to 3 year old threads.

You should open a new thread instead. This helps you because only the people that subscribed to the original thread will see your post (and that implies they're still around to see it). New posts have a much higher visibility because they go into the "zero replies" queue that many of us examine.

The way to enable telnet on RHEL5 is pretty much the way I posted above for RHEL3 3 years ago though there might be slight differences in the file.

Telnet is a insecure protocol b'se it sends data with plain text format.
Defaulty telnet disabled to root.
you check first,whether telnet running or not with below command.

# pgrep telnet
if it shows pid,running telnet or service telnet restart,if you want to run at next reboot chkconfig telnet on

configuration file
/etc/xinetd.d/telnet

you try to enable,its so easy.
