Trying to eliminate one player. The destination Solaris machine has an impact. There are two Solaris servers on the same subnet. For one of the servers: Solaris ftp put to linux is fast Solaris ftp get from linux is slow Linux ftp put to solaris is slow Linux ftp get from solaris is slow For the another Solaris 8 server on the same subnet, all ftp xfer's with Linux machine are fast. When the machine is booted into XP, ftp is fast to either server. >> dmesg shows "e1000: eth0 NIC Link is Up 100 Mbps Full Duplex". > This feels like a duplex mis-match. The Solaris server that is slow for most Linux ftp xfers has 100 MBPs full-duplex forced. The Solaris server that Linux talks to fast doesn't have any duplex/capabilities forced. I tried 4 Solaris servers. 2 had forced full duplex and 100 Mbps. Those are slow. 2 other Solaris servers on the same LAN as the "slow" Solaris servers are fast. These "fast" servers are using default settings (which should also be 100 Mbps full-duplex). The odd part is that XP will talk to all four Solaris servers fast. -- Randy Hron http://home.earthlink.net/~rwhron/kernel/bigbox.html
