With Slack 10.2 and 2.4.31 I could log in from my windows machine through telnet on port 23.

I changed to kernel 2.6.13 and loaded the kernel modules and everything seemed fine.... except I lost the telnet login. Telnet server is running, because I can upload and download with other programs that use it.

The conf files thatI know about seem to be OK.

In the end, the question is, "How can I make aconsole available through telnet?". Inittab is the same as it was before and also inetd.conf

Something in modules must have stepped on something!

can you telnet in on localhost?
does ssh work?

You really should be using SSH. Telnet is massively insecure.

telnet on localhost responds with
Escape character is '^]'
Connection closed by foreign host.

The telnet from another machine actually seems to find the server and seems to wait for an input, but on typing the first character it exits. It doesn't output thelogin message either.

I'm sorry, I've been a programmer for 30 years.... but I'm relatively new to Linux ( although I do wonder why I waited so long ) so forgive this next question.....

What's ssh. Secure shell isn't it?

Anyways, security isn't really an issue. The unit is an embedded box on a tecnical network that doesn't really have any "private" information. Hackers aren't really a big problem, althugh virus control might be... but I don't know much about Linux viruses yet...

hmm.

read `man in.telnetd`
then edit /etc/inetd.conf
and put it into debug mode

Kodon,

That got me part way there...

In debug, I saw that I could connect on port 40, so I thought that maybe somebody else had 23 taken. So i changed /etc/services to put telnet on 40, and got the same thing as before.

If I remove any reference to telnet in /etc/services, and start it in rc.local in the background with port 23, everything works fine... but I imagine that's not the best way to be doing it.

Whether it's commented out or not in inet.conf doesn't seem to make a difference, as long as I leave it out of services. ??

So....??

SSH is much more secure, but that isn't the only advantage. SSH is also much more flexible than telnet. Things like SCP, SFTP, FreeNX, etc.

RSA key login is also nice to have when working frequently on a machine, as is being able to run commands on the remote machine without actually having to login first.

strange
not sure why standalone would work
and not the tcp wrapper

is it just telnet or everything that uses a wrapper?

Checked inetd and it's fine. I can run systat and netstat for instance remotely without problems.

Perhaps something in the telnet server is slightly incompatible with ker 2.6. Or I have a telnet version compatible to 2.4, but while running 2.6 kernel. ?

i'm running: 2.6.15.5, tcpip-0.17-i486-36, inetd-1.79s-i486-7
without any problems...afaik, none of my kernels gave me any
problems.

did you roll this kernel yourself?
if so, double-check your config...

Kodon,

I've got 2.6.13, tcpip-0.17-i486-35 and inetd-1.79s-i486-7 so it's in the ballpark. Don't know, maybe I should reinstall tcpip or inetd. My kernel was pre-fabbed by Slack

Actually I'm not sure if I lost the telnetd console connection with the upgrade from Slack 10.0 to 10.2 or with the change from ker 2.4.31 to 2.6.13.

I'll struggle through until I find the solution.... best way to learn I guess.

Thanks for the help,
Dave

There is ALOT of possibilities there.

By chance when you installed 2.6.13, was it test26.s install kernel? If so did you use cd2's 2.6.13 directory to get 2.6.13 kernel-modules and other needed pkgs-not 2.6.13 kernel-headers? Or did you install 2.6.13 from cd2 kernel-source by making initrd image? If you installed test26.s the 1st way maybe you need its kernel-modules pkg too, especially if you get module errors. Just a thought.hmmm.

Lestoil,

Installed the 2.6.13 test then installed the modules from disk 2. Installed alsa-drivers too, although I realized that I didn't need those. Didn't install the generic though. NOt sure what those are.

I haven't ever compiled or rolled my own yet... still too green.

Thanks,
Dave

Many users that are not so green never compile a kernel and use SW happily. But if you ever want to install nvidia drive,for example,you will need the 2.6.13 kernel-source package on cd2 /2.6.13 too. Enjoy.
