FTP and TELNET Session Banner

[JUAN_17]

Hi everybody!

Sorry! my english is too bad!

When i login in my public Server via FTP, the server displays the banner
220 200.75.264.88 FTP server (Version wu-2.6.1-18) ready.

I need to change this banner, and the TELNET banner. How i can do this?

Thanks from Venezuela!

The telnet banner is changed via the /etc/inetd.conf file.

Add the following to the end of the command:

-b /etc/issue

You can change "/etc/issue" to any file that you want to store the banner information you want to be displayed.

Then recycle inetd by issuing "inetd -c".

Hi:

For the 'telnet' banner, edit '/etc/inetd.conf' for the 'telnetd' daemon and specify the banner file you want with the -b bannerfile' option. For instance:

# telnet stream tcp nowait root /usr/lbin/telnetd telnetd -b /etc/issue

Then reconfigure:

# /usr/sbin/inetd -c

For the 'ftpd' daemon's banner configure the option in the 'etc/ftpd/ftpaccess' file. See the man pages for 'ftpaccess(4)'.

Regards!

This feature is only available on HP-UX 11.x or later,
and is not available on HP-UX 10.20.

A ???banner??? is displayed when the ftp user connects, before the user enters a
username and password.

A ???message??? can be displayed after the ftp user enters a username and password
and has logged in, similar to Message of the Day (aka /etc/motd).


To add a banner and/or message:

1. In the /etc/inetd.conf file, verify that the -a option is added
to the ftpd daemon line to allow use of the configuration file
/etc/ftpd/ftpaccess. Modify /etc/inetd.conf if necessary.

ex: ftp stream tcp nowait root /usr/lbin/ftpd ftpd ???l -a

2. Modify the file /etc/ftpd/ftpaccess as needed, adding or changing
the ???banner??? and/or ???message??? directive.

NOTE: If /etc/ftpd/ftpaccess does not exist then it is recommended to
copy the ftpaccess file from /usr/newconfig/etc/ftpd/ftpaccess
to /etc/ftpd/ftpaccess and modify accordingly. If a blank
/etc/ftpd/ftpaccess is created, then be sure to also define
a ???class??? directive, otherwise failing to define a valid ???class???
for a host will cause ftp access to be denied.

For a ???banner???
add line: banner

ex: banner /etc/myftpbanner

For a ???message???
change line: message /welcome.msg login
to: message login

ex: message /etc/myftpmessage login


3. To reread the inetd.conf file and cause ftpd to use the
new /etc/ftpd/ftpaccess file execute:

#inetd -c

4. Use ftp to test the new ???banner??? and/or ???message???.


For more information please see man pages for ftpd, ftpaccess, and ftpusers.

1. To enable a telnet login banner:
Add the desired message to the /etc/telnet_banner file.

Add the following entry to the end of the telnet line in the /etc/inetd.conf file:
-b /etc/telnet_banner
For example:

telnet stream tcp nowait root /usr/lbin/telnetd telnetd -b /etc/telnet_banner

2. To enable an ftp login banner or message:

NOTE: This feature is available on HP-UX 11.x or later.

Enable ftpd to use the /etc/ftpd/ftpaccess configuration file.


Add a '-a' option to the end of the ftp line in the /etc/inetd.conf file.

For example:

ftp stream tcp nowait root /usr/lbin/ftpd ftpd -l -a

Add a message or banner line to the /etc/ftpd/ftpaccess file.

NOTE: If the /etc/ftpd/ftpaccess file does NOT exist, copy the /usr/newconfig/etc/ftpd/ftpaccess to the /etc/ftpd/ directory and modify it accordingly.

If a blank /etc/ftpd/ftpaccess file is created, be sure to define a "class" directive, otherwise ftp access will be denied.

For example:

banner /etc/ftp_banner
message /etc/ftp_message login

3. Reread the /etc/inetd.conf file:

inetd -c

Hello!

For ftp:
in /etc/inetd.conf line of ftpd made this: ...... /usr/lbin/ftpd ftpd ???l -a
and write the message to /etc/ftpd/ftpaccess
(* copy /usr/newconfig/etc/ftpd/ftpaccess)

For telnet:
in /etc/inetd.conf line of telnet made this: ...... telnetd -b
and write message to

In the end you need that inetd will run with
new changes so run: inetd -c
