Want to block ftp for root user
Hi Friends,
I would like to block the root user for doing ftp. As I am aware that I need to put the entry for root in /etc/ftpusers.....am I right...??? But I am not able to edit the file & even more command is not working.
#ls -l ftp*
total 14
-rw-r--r-- 1 root sys 1249 Jun 23 2006 ftpaccess
-rw-r--r-- 1 root sys 551 Jun 23 2006 ftpconversions
-rw-r--r-- 1 root sys 104 Jun 23 2006 ftpgroups
-rw-r--r-- 1 root sys 108 Jun 23 2006 ftphosts
-rw-r--r-- 1 root sys 114 Jun 23 2006 ftpservers
-rw-r--r-- 1 root sys 186 Jul 19 2006 ftpusers
etc]# more ftpusers
ftpusers: No such file or directory
etc]# cat ftpusers
cat: cannot open ftpusers
Even when I try to vi this file, it opens the new file.
Can someone suggest me whats wrong.....???

ftpaddhost
ftpaddhost(1M) System Administration Commands ftpaddhost(1M)
NAME
ftpaddhost - set up a virtual FTP host
SYNOPSIS
ftpaddhost -c | -l [-b] [-x xferlog] hostname root_dir
DESCRIPTION
The ftpaddhost script is executed by the super user to set up virtual FTP hosts. The ftpaddhost command configures the virtual host host-
name under directory root_dir. The value of hostname can be an IP address or the name of a host.
OPTIONS
The ftpaddhost script supports the following options:
-b Create a banner for the virtual host. This option is useful to confirm that the virtual host is working.
-c Configure complete virtual hosting. This option allows each virtual host to have its own version of the ftpaccess,
ftpconversions, ftpgroups, ftphosts, and ftpusers files. The master version of each of these configuration files is
copied from the /etc/ftpd directory and placed in the /etc/ftpd/virtual-ftpd/hostname directory. If the
/etc/ftpusers file exists it is appended to the virtual ftpusers file. If a virtual host lacks its own version of a
configuration file, the master version is used.
-l Configure limited virtual hosting. This option allows a small number of parameters to be configured differently
for a virtual host. See the virtual keyword on the ftpaccess(4) manual page.
-x xferlog Create a logfile entry such that the transfer logs for the virtual host are written to the specified file. An abso-
lute path must be specified for the xferlog file.
OPERANDS
The following operands are supported:
hostname The host name or IP address of the virtual server.
root_dir The absolute pathname of the directory under which the virtual server is set up.
EXIT STATUS
The following exit values are returned:
0 Successful completion
1 Improper usage of the command
2 Command failed
FILES
/etc/ftpd/virtual-ftpd/hostname The configuration files directory for the virtual host hostname.
