[prasathc]

Hi guys

I have small problem while telnet, for the J5600 series machines, having the os of 11.00. I am able to ping and rlogin to that machines but not able to " telnet "

When i try to telnet < host name > it's giving error message as follows

# telnet waves
Trying...
Connected to hpcvl150.india.hp.com.
Escape character is '^]'.
telnetd: /dev/pts/t0: No such file or directory
.
Local flow control off
Connection closed by foreign host.

what could be the problem, can u please guide me

thanks in advance

Hi,
check whether do you have telnetd file under /usr/lbin. this will be linked to /etc/telnetd, which will be executed by inetd. If the file doesn't exist do ftp from other machine and reboot. if the file exist check for inetd process and services using SAM(whether telnet is enabled or disabled)

Hi

When telnetd start it connect to applications
with a pseudo-terminal : /dev/pts/t*. The
number of terminals can be modify with the
parameter "nstrtel" (sam/kernel configuration/tunable...).

I think you can verify this parameter, verify
you can access to /dev/pts/t*. I haven't any
/dev/pts/t0 file and telnetd works well...
For more information see :
man telnetd
man tels

You have to install telm driver.

Hi,

Please check in /var/adm/syslog/syslog.log
for any telnet message.
try telnet to your self.
if in syslog say not enough pty
then youi have to increase kernel paramater npty and nstrpty.

Ran the command insf -e and the system started accepting telnet
connections from then on.

Hi,run this command : " insf -d tels -e " , this will create the /dev/pts/t* file for you ( Telnet need this for slave device ).

For furthur info , you can " man insf "

Hi

First U check up whether telnet is enabled or not in /etc/services file. If not , Uncomment the line telnet and run inetd -c.

Second thing is checkup whether device files are available in /dev/pts directory.

Best of luck
