Hi,

On one PC I cannot do telnet due to "Bus error". What could cause this?

[root@###] telnet
Bus error

telnet port is open:

tcp 0 0 0.0.0.0:23 0.0.0.0:* LISTEN 10584/xinetd

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


[root@###]# cat /etc/redhat-release
CentOS release 4.5 (Final)

try

Code:

gdb telnet
run

then when it traps do

Code:

bt

to get a stack trace.

How to look at this?

(gdb) run
Starting program: /usr/kerberos/bin/telnet

Program received signal SIGBUS, Bus error.
0x00fae977 in ?? ()
(gdb) bt
#0 0x00fae977 in ?? ()
#1 0x008492f4 in ?? ()
#2 0x00fa1cdb in ?? ()
#3 0x008492f4 in ?? ()
#4 0x00000000 in ?? ()
(gdb)

What does

Code:

ldd telnet

say?

Do you have kerberos set up?

Do ftp or ssh work?

ldd: ./telnet: No such file or directory

what is kerberos?

ssh works fine.

Code:

which telnet

then plug the returned path into

Code:

ldd that-path-to-telnet

ftp throws "Bus error" as well...
