I only get 15kb with ftp what can I do to solve this problem. I found the result of netstat -s quite strange. why so many tcp packet have a bad checksum. no errors are detected by ethernet switch (synoptics) Thanks for your help -- Didier Derny | My computer is Microsoft Free... didier@omnix.fr.org | FreeBSD 2.1-STABLE site
