I assume you use .csv files. Then: - use DBI::CSV, not DBD::File - make sure your file is correct, ie first line contains columns names not values and use the correct delimitator (default seems to be comma)

$SIG{'ALRM'} = sub { die "Timeout exceeded, exiting\n"; }; alarm($your_timeout); You could use this trick in an eval block to timeout just a part of the program and handle the timeout gracefully.

Already talked to 3Com. 4250 does not support link aggregation on 10/100 ports (and "get a 4400 instead" is not a valid option). And btw it does not implement per-vlan stp as it should, instead it runs one stp process for all ports no matter which vlan they belong. Case closed. Next time I'll...

@tlds3 = &quot;.com.net.org&quot;; I'm not sure what you expect by initializing an array with a scalar, it doesn't make sense. Depending on what you want in that array, maybe @tlds3 = qw(.com .net .org) ?

Which line is 123? Is $condition initialized when you enter the while loop?

Any well designed power supply should last long enough on the internal capacitors to survive a ups switch from line to battery or viceversa. If you really like to mess with your switch (and possible damage it for good), you can try to locate filtering capacitors on the dc output of the power...

Make sure the switches support port aggregation on the desired port types (some do only on gbit ports). If they suport LACP and it is enabled, aggregations will be autodetected. If not, you have to configure them by hand on each switch. Resilience is for backup links (secondary links are not...

Or you can monitor port traffic for each port via snmp.

Hi, I cannot figure how to configure a multiple 100mbit port aggregation between a 4250T and a 3300 switch. To be specific the 3300 seems to know only manual aggregation (which is perfectly fine with me) _but_ the 4250 does not let me define a manual aggregation on other ports then 49 or 50...
