Description Bertil Askelid 1999-07-31 13:50:38 EDT
/usr/bin/ftp has to installed with suid bit set:

	chmod 4755 /usr/bin/ftp

Same error occures for telnet and fwhois.
Comment 1 Bertil Askelid 1999-07-31 14:53:59 EDT
My suggested solution is no good. Means that ftp:ed files are owned
by root. Thus, there must be something in the tcp that prevents ftp,
telnet and fwhois to be used by a regular user. But what?
Comment 2 Bertil Askelid 1999-07-31 15:31:59 EDT
Problem solved: /etc/services comes with rw------- on the 6.0 CD.
Should be rw-r--r--.
Comment 3 Bill Nottingham 1999-07-31 17:46:59 EDT
No, it comes with the correct 644 permissions (just checked here.)
Perhaps something else changed them on your system. Did you install
the samba upgrade with a non-default root umask?
Comment 4 Jeff Johnson 1999-07-31 19:03:59 EDT
No, don't put a setuid on the program, check the permissions
on /etc/services. I believe that a recent update (samba?)
changes the permissions to 600 on /etc/servcies. Can you confirm
   1) you recently installed the samba update.
   2) the permissions are 600 on /etc/services
so I can get this problem fixed? Thanks ...

This problem appears to be resolved.
