telnet connection refused

Marcusj2 · 12-22-2002, 12:00 AM

Hello,

I have installed redhat 7.2 onto an older pentium. inetd services are running and I can telnet to localhost. I can also ftp to localhost, however I cannot either telnet or ftp to the box from another machine on the same network. When I attempt to I rereceive the message connection refused.

I have read other messages talking about checking the /etc/inetd.conf file for certain entries however I do not have an /etc/inetd.conf file AND I have connected to another redhat host running a slightly different kernal version of redhat than the one I am using and it does not have the /etc/inetd.conf file either AND it seems to work just fine for both telnet and ftp. I am curious if somehow a firewall is running on my box but I don't know how to tell for sure. I have tried ps -ax | grep fire and came up with nothing.

Please help,

Thanks,

Marc

turn firewall off

/etc/rc.d/init.d/ipchains stop

or

/etc/rc.d/init.d/iptables stop

locate inetd.conf

/etc/xinetd.conf

Hello David,

Thanks for the reply. In the meantime I edited /etc/sysconfig/ipchains and added the following lines:

-A input -s 0/0 -d 0/0 25 -p tcp -y -j ACCEPT
-A input -s 0/0 -d 0/0 80 -p tcp -y -j ACCEPT
-A input -s 0/0 -d 0/0 21 -p tcp -y -j ACCEPT
-A input -s 0/0 -d 0/0 22 -p tcp -y -j ACCEPT
-A input -s 0/0 -d 0/0 23 -p tcp -y -j ACCEPT

I then rebooted the box. That seems to have fixed the issue, I can now both Telnet and FTP to the box in question. I will now however, revert to the unedited version of the file and attempt your recomendation.

Thanks again,

Marc

my recommendation was to simply see if it was a firewall issue before we go posting all possible senarios. It obviously was the firewall, so there's no need for any more testing.

thanks, that worked perfectly....

Hi Marc,
I have done all these things (including the entries in /etc/sysconfig/ipchgains). But still it is not working((

Hi David,

What should I do?

DavidPhillips · 01-06-2003, 12:08 PM

open a xterm or type in a terminal the command

Code:

service telnet on

it might do something, it depends on your distro

No. It did not work.

When I typed /sbin/service telnet on
I got
telnet: unrecognised service

I have "telnet" service defined in /etc/services file.

Any clues!!!

DavidPhillips · 01-07-2003, 02:32 AM

I would say it's not installed

try rpm -qa | grep telnet

you probably only have the telnet client installed, and not the server

What are you using Mandrake?

to turn the telnet service on, please use the command:

chkconfig --level 345 telnet on

To make sure that the telnet-server is in your system issue the command:

rpm -q telnet-server

DavidPhillips · 01-07-2003, 03:10 PM

That's not going to work right, telnet is a service in xinetd.d.
You can use chkconfig if you want to instead of service.
To use chkconfig, the command is

Code:

chkconfig telnet on

It's not installed in initd, so levels are not supported

[root@localhost root]# service telnet on
telnet: unrecognized service
[root@localhost root]# chkconfig telnet on
error reading information on service telnet: No such file or directory
