Operating Systems SCO Need Help With System Recovery After HD Errors Post 302992159 by rbatte1 on Wednesday 22nd of February 2017 07:42:09 AM

Going back to the question about limiting FTP users, I regret that I don't have a SCO server available to test, however many unix OS variation have a file /etc/ftpusers which work in the reverse to what you might expect. It is a list of accounts that are not allowed to FTP into this server. It is slightly counter intuitive (to me at least Smilie) but I wrote a simple script that I run daily to read /etc/ftpusers.allowed and re-write /etc/ftpusers. It was something like this:-
Code:
cut -f1 -d":" /etc/passwd | grep -vf /etc/ftpusers.allowed > /etc/ftupusers

Would that help? You need to be careful that the input file doesn't have blank lines (which will match every record) or short user ids that are contained within longer ones. Perhaps you should make this a two step process:-
Code:
sed 's/^/\^/ ; s/$/\$/' /etc/ftpusers.allowed > /tmp/ftpusers.allowed
cut -f1 -d":" /etc/passwd | grep -vf /tmp/ftpusers.allowed > /etc/ftupusers


I hope that this is useful on SCO. Apologies if it's not. have a look at th emanual page for ftpd or whatever offers the service for you.

Kind regards,
Robin

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. ATTRIBUTES
