I am using the Thinkpad as a server for a Dec Network Computer. I have a similar setup using Gateway 486/66DX2 as server and it works flawlessly. However, my Thinkpad has network connectivity problems serving files to the NC. The NC uses TFTP to download boot image, then uses NFS to access root and usr filesystems on Thinkpad. TFTP seems to be OK, but NFS part flakes out. I get the following errors: /kernal: nfsd send error 55 (repeated many times) Also, pinging other UNIX boxes on my network gets this error: ping: sendto: No buffer space available Also, netstat -s shows many UDP datagrams dropped due to no socket. Looks like I need to do some TCP configuring, but I am very rookie with FreeBSD configurations. Any body have any suggestions (other than the obvious about the Thinkpad) on where/how to tune tcp settings? Also, is there any difference between 2.2.5 and 2.2.1 (my Gateway version) in networking, specifically NFS support? TIA Chris Sagar csagar@iterated.com
