telnet is not working

JackDante · 08-02-2004, 08:58 AM

Hi

While trying to solve a problem I created another one.

I cannot telnet to my local machine ... 127.0.0.1 Connectione refused.

Here is what I did: uninstalled sendmail and had to unsinstall mdadm, fetchmail, mutt.

chkconfig --list telnet ... returns: error readig information on service telnet: no such file or dir.

So what I guess: I somehow "managed" to remove telnet (it was there) while uninstalling sendmail (rpm -e sendmail)

HOW do I reinstall telnet?

Thx

first do a query to rpm to see if the package is installed:

rpm -q telnet

if rpm returns with the package being installed, then all you have to do is replace the xinetd file.

if not, simply reinstall the package.

hope i could help!!!

thanks, telnet is now on, but connection still refused. Yes I rebooted the machine.

Will a reinstall help?

Any comments?

you should never have to reboot a linux system.

first, if you are running iptables.... stop it to see if that is the problem.

Code:

/sbin/service iptables stop

then, if that doesn't work, save the following as a file named telnet in /etc/xinetd.d :

Code:

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

then restart xinetd:

Code:

/sbin/service xinetd restart

hope i could help!!!!

also, if the telnet file exists in /etc/xinetd.d then, make sure the line disable = yes is set to either no, or the line is just totally deleted.

side note: if you will be connecting remotely via internet, then i recommend using ssh.

always glad to help. let me know if you need anything else!

JackDante · 08-03-2004, 03:39 AM

hmmm

reinstall did not help.

here'S what i did
- downloaded 0.17-30 installed it
- rpm -q states telnet
- chkconfig --list telnet states on
- /etc/xinitd.d/ contains telnet file with same contents as yours

telnet 127.0.0.1 25 -> connection refused

any ideas apart from reinstalling fedora system (Windows aproach)

many thanks ... hope that some time i will be able to help others ....

If that wasn't a typo telnet listens on port 23 by default, port 25 is SMTP.

JackDante · 08-03-2004, 05:53 AM

it wasn't a typo (i'm telnetting to test mail) ...

port: 23 doesn't work either

can you do "netstat -tulanp" as root and see if its listening on 23 and 25.

JackDante · 08-03-2004, 06:23 AM

netstat -tulanp

does not show any 23 or 25 ports

is there any service needed for running telnet ... apart from IP...i am currently typing on this box.

i guess it's error 40

for telnet as mentioned in the previous posts it needs to to launched by xinetd, so xinetd services needs to be started, and in the configuration file change disable = no.
For SMTP you need to configure your MTA

JackDante · 08-03-2004, 06:42 AM

well

xinetd is started and the telnet file looks as mentioned by LLL only i added disable = no, although it is probably not needed.

thx JD

JackDante:

correct me if i'm wrong but reading your post seems like you installed telnet (client) but you haven't installed (or reinstalled) telnet-server package??
