I've found that the xferstats program shipped with RH5.2 does not calculate the number of systems using an ftp site and that this is due to a missing line in the script itself. The ftpd xferstats script shipped with 5.0&5.1 contained the same bug... Here is the diff: -cut-cut-cut- 106a107 > $systemfiles{$line[6]}++; # Systems Accessing the Arc -cut-cut-cut- [!!!already reported for RH 5.0!!!]
This appears to be a suggestion for improvement of the product.
the script author clearly intended to keep a count of systems connecting to the server, but forgot a line in the script; imho, this is not a suggestion for an improvement (otherwise, the $systems array wouldn't be there in the first place), just a bug, although surely not your fault (it is in fact present in the pristine source)
Fixed in the current beta
