telnet not working on sles 10

**gounix** · 06-26-2008

hi all,

i'm new to linux, so please bear with me.

I have just installed sles 10 on a dell poweredge 2900. i need to be able to telnet into this box.

when trying to telnet, i get the following message:

/usr/lib/mit/sbin/login.krb5 , no such file or directory.

i have a specific need to use telnet, so if you can't provide a solution to this problem, please don't reply and tell me to use ssh or some other more secure program.

i am aware of the inherent security issues with telnet.

thanks

Hello
check if the krb5-server package is installed

**gounix** · 06-27-2008

thanks for your response.

i'm not sure how to check to see if that package is installed and if it is not, i certainly don't know how to install it.

i have checked the services under xinetd and there is no service named krb5-service shown.

as i said i am very new to linux and do not understand a lot of the terminology yet.

Go to Yast-Software-Software Management and do a search. If it is not installed select to install it.

It really is pretty simple once you know where to go.

thanks. it was pretty easy once i realized that i needed to install it from the installation cd's.

i found it on cd 3 and installed it and now i have the login.krb5 file.

however, when i try telnet <ip address> i get a new message:

"could not open connection to host, on port 23: connect failed".

i think i am close.

Did you open the port in the firewall??

**gounix** · 06-30-2008

the firewall on the linux box is disabled. i tried to use telnet localhost and got the same message.

i don't have a firewall on my pc.

not being a network person, it does seem to me that some service may not be running. that is just a guess.

again, thanks for your help. i really appreciate it.

Do you have a telnet server installed? (The missing "i" to the left means it's not installed in the example below.)

If installed, is xinetd listening for port 23 connections?

Code:

chkconfig -l | grep telnet

**gounix** · 06-30-2008

the chkconfig command shows 2 items
ktelnet off
telnet off

in the network services screen under xinetd, i don't see ktelnet listed but i do have 2 listings for telnet,

both of the telnet listings have a - (dash) in the status column. if i try to enable them, i get a popup message that says: Package telnet-server was successfully installed on one of them and the message: Package krb5-apps-server was successfully installed on the other one.

thanks for you help!

How are you trying to "enable" them?

You need xinetd "on" and "telnet" on.

Code:

chkconfig -s xinetd on

Code:

chkconfig -s telnet on

Then check them:

Code:

chkconfig -l

And see if port 23 is open:

Code:

netstat -anp | grep 23
