XP shared dir Not mounted] I have a similar situation here, but with an additional interesting observation. If I copy a file from WinXP to an SMB share on a Gentoo server with the XP explorer, I get about 2MB/s throughput, which is not all too much on a 100Mb/s network. However, if I run the following command in the background (eth0 being the interface over which I copy): tcpdump -n -i eth0 >/dev/null the throughput increases to about 8-10MB/s! I have no idea where this could come from. The only explanation I can see is that tcpdump puts eth0 into a sort of promiscuous mode, which interacts favorably in the SMB protocol. But I haven't been able to figure out how I should tune eth0 to get the same results without tcpdump. -- Remy Remove underscore and suffix in reply address for a timely response. -- gentoo-user@gentoo.org mailing list
