Unhappy telnet local but no-telnet via internet


The system is RedHat 7.1.

I have read so many posts regarding telnet not working that the answer must be in here somewhere but it still doesn't work for me.

#ifconfig -a produces an inet addr which is my direct, permanent ip address along with Bcast of the same address except that the last number is 255 and Mask:255.255.255.0

#route says Destination ns1.isoc.net with Gateway ddsl-router.wil Genmask 255.255.255.255 Flags UGH Iface eth0;
next line Destination my ip address except last number is 0 with Gateway * Gnemask 255.255.255.0 Glags U Iface eth0;
Destination 127.0.0.0 Gateway * Genmask 255.0.0.0 Flags U Iface lo;
Destination default Gateway ddsl-router.wil Genmask 0.0.0.0 Flags UG Iface eth0
Metric, Ref and Use are all 0

#cat /etc/hosts gives
127.0.0.1 acti localhost.localdomain localhost
192.168.0.50 ppp01 ppp01.americotec.com
192.168.0.100 acti markt

#cat /proc/sys/net/ipv4/ip_forward results in the single digit "1".

allow.hosts is set to ALL : ALL

The IP address will ping via the internet and telnet to the IP works fine via the local hub from my win98 box, BUT you cannot telnet to the IP address via the internet.

HELP! I have had about 4 hours sleep for two nights running trying to dope this thing out and seem so close but yet so far....

I am going to help my daughter with her oboe. Hope some of you gurus have an idea what is wrong. Thanks...

This was tough for me to

First I am unsure of the unspecific of how this works but here it is simply out:

First of all I am suspecting that you did a "Workstation" install in which there is no telnet daemon running to answer requests for access to your computer, but there is a service to telnet out.

The only way to fix this this is to install this telnet daemon or so with a traditional "Server Class" installation

Note: All of this is assumed that you are using RedHat as this the distribution I am making references to.

Hope this helps.

telnet service

Would my local win98 machine be able to telnet to the RedHat machine if there were no telnet daemon running?

ps aux | grep telnet produces no reply which may be saying that the telnet daemon is not running.

What is the exact command to get telnet daemon running?

telnet daemon

if I was right about the 'Workstation-Class' installation there is no telnet daemon to serve remote requests. It has to be installed. I can't help you with installing as I have never done it.

This is from RedHat 7.2 so your version may differ...

# rpm -qa | grep -i telnet
telnet-server-0.17-20
telnet-0.17-20

Telnet passes the username and password "in the clear". In other words, NOT encrypted. I'd highly recommend installing and using SSH instead. It does everything telnet does as well as most of what ftp, rsh and a few other things do execpt that it does them securely and encrypted.

# rpm -qa | grep -i ssh
openssh-askpass-2.9p2-9
openssh-2.9p2-9
openssh-server-2.9p2-9
openssh-clients-2.9p2-9
openssh-askpass-gnome-2.9p2-9

If this system is accepting local Telnet requests.. then the daemon is installed and working. For more proof, issue:

chkconfig --list telnet
or
service --status-all (and there will be something listening on port 23)

What message ... exactly... does the client receive when trying to telnet in?

Check the /var/log/messages and /var/log/secure on the server for messages when the client tries as well.

Do you have anything in /etc/hosts.allow or /etc/hosts.deny ?
