Roy, I use tethereal with -a regularly.
The -a duration is checked for expiry _after_ each packet is received. If no packets are ever received past the capture filters the timer expiry will never be checked. I consider this a feature not a fault. Regards, Tim Everitt. Tim Everitt tel: +44-1224-355291 mobile: +44-7970-331327 fax: +44-1224-355292 email: [EMAIL PROTECTED]
