THE VIRTUAL SERVER HANDBOOK

Monitoring Anonymous FTP Activity

The messages file located in your usr/logs directory contains valuable

information describing how often your virtual anonymous FTP server is

being used. This information is not very readable, though. You can use the

Xferstats

 program to summarize anonymous FTP activity.

Xferstats

 may be run periodically by the CRON facility.

To use XFERSTATS to monitor FTP activity:

1.

Create a file named cfile with the following information:

# Crontab file (see crontab(5))

# Every Sunday morning at 2:13am process FTP

xferstats and "nuke" message file

13 2 * * sun /usr/local/bin/xferstats  m

user@xyz.com  n

2.

Run crontab to install the cron file (cfile) you just created:

{1} % crontab cfile

To see more information on cron, enter 

man

crontab

 and 

man 5

crontab

 at your virtual server s UNIX prompt.
