Hello Dave,

You need to add a line to your /etc/ftpaccess file like:

class all real,guest,anonymous *

Chances are you already have this line as a comment on your /etc/ftpaccess file. If that's the case, just remove the comment char (#).

Note that you should be able to login as a regular user, not root. If you also want to open ftp for root (not recommended!!!):

- Edit /etc/ftpusers and remove 'root' from there
- Comment the lines (add a # on the first column) where you see 'deny-gid' and 'deny-uid' in your /etc/ftpaccess file.

Hope it helps,
Paga

Hello,

You *should* be able to ftp as root if you did the configurations I mentioned above. If ftp is refusing your root connections, it should be sending something to /var/log/messages or /var/log/secure. Check it there and let me know if you find anything funny coming from ftp.

Also, if you want to telnet as root, add pts/1, pts/2, pts/3 (and a whole bunch of them until pts/N) to /etc/securetty. That should do the trick for you.

Paga

Hello Dave:

Two things:

1) For telnet:

Did you put pts/1, pts/2, pts/3 etc on your /etc/securetty file?

2) For FTP

Did you comment out the 'deny-uid' and 'deny-gid' lines on /etc/ftpaccess? Also, don't forget to remove the 'root' line from /etc/ftpusers!

Let me know as it goes.

Paga

Hi Dave,

for telnet:

modify /etc/securetty and add entries for pts/1, pts2,pts/3,...etc

for ftp:

modify /etc/ftpaccess:

comment out 'dent-uid and deny-gid'

uncomment 'class all, real,guest, anonymous *'

modify /etc/ftpusers

remove 'root'

modify the following entries:

/etc/xinetd.d/wu-ftp 'disable=no'

/etc/xinetd.d/telnetd 'disable=no'

then restart xinetd daemon:

/etc/rc.d/init.d/xinetd restart
