Hi,
have you checked the file /etc/inetd.conf .
Look for the telnet line, which would call a file.

From a security point of view, you shouldn't be running telnet at all. All network traffic, including passwords, is transmitted in cleartext.

Hello,

You can check for that at the following files.

/etc/motd
/etc/profile or $HOME/.profile , but actually I believe that these two option are the right for you.

Try that, and let us know your results trying to enter to the system again.

Check this out.

At the end of my "/root/.profile" you can see the following. :

# Set up shell variables:

MAIL=/var/mail/root
# don't export, so only login shell checks.

echo "WARNING: YOU ARE SUPERUSER !!\n"
export HISTFILE=/root/.sh_history
export HISTSIZE=3000
umask 022
PS1=`id -un`'@'`hostname`:'${PWD##//}> '

----------------
Probably you have something like that with that message in your .profile file.

Check the /etc/copyright file, which is cat'd in /etc/profile.

Hello John,

Actually I see that the banner you say could not be removed and is part of the system.

http://docs.hp.com/en/5991-6482/ch03s10.html

AFTER logged into the system, you can see reflected the other banner such as /etc/motd, /etc/issue, /etc/copyright , and the .profile files.

I believe that info cannot be remove it from there.

Regards.

Well...., I'm talking about telnet..., telnet shows that..., if you connect to the server using ssh you will not see that, so ...I think that maybe modifying the /etc/inetd.conf file or something like that you could achieve that, but ssh doesn't show that.

ok. this msg :
"HP-UX Hostname B.11.11 U 9000/800 (tb)"
is the default for telnet

to remove it do the following:
a) create a file containing whatever you want this to say instead of the above msg. this file *can* be empty if desired. for this example, we're going to call it "/etc/blankfile"

b) edit /etc/inetd.conf. find the line w/ telnetd. you need to add
"-b /etc/blankfile" to the end so that it looks like this:
telnet stream tcp nowait root /usr/lbin/telnetd
telnetd -b /etc/blankfile

c) restart inetd running
"/usr/sbin/inetd -c"

the offending message should be gone

wow..., was close!!! =), good tip partner .., I knew that the inetd file was in the issue but don't knew what to change on it...

Thanks!
