How to change ftp banner ?

[samjoo]

Hi!
I need to remove version of ftp login banner for security and did following action:

#dspcat -g /usr/lib/nls/msg/en_US/ftpd.cat > /tmp/ftpd.msg
I've removed "%s" of 9th line in the ftpd.msg file using vi editor and then run following command;
#gencat /tmp/ftpd.cat /tmp/ftpd.msg
#cp -p /tmp/ftpd.cat /usr/lib/nls/msg/en_US/ftpd.cat
#refresh -s inetd

But system still show me the ftp version.
Could anyone explain me why this problem stiil happened?

thanks in advance!

I foung the string in ftpd binary file using "strings". I believe if you use ftpacces.ctl fiel (see man pages)you can tell it not to display the hearld. You will need to stop the daemon and restart it after making the changes to ftpacces.ctl

samjoo,

Double check your process. It worked just as expected on my machine. Maybe your LANG or that of ftpd is to something other than "C" or "en_US". plamb is not referring to AIX ftpd, which does not use an ftpaccess.ctl file.

If you are tightening security and access i'd disable telnet & ftp and use ssh & scp
