I'm using FreeBSD 5.21 with a dialup modem, and I'm having problem uploading files and sending emails with attachments through the Fastmail.fm mail service - the connections just time-out. Ordinary web browsing and short text emails work normally with Fastmail. File uploads to other sites work and file uploads to Fastmail works from Windows 98.
I'm guessing that this is a path MTU discovery blackhole, since if I set sysctl net.inet.tcp.sendspace=400 the problem goes away. (I presume that net.inet.tcp.path_mtu_discovery: 1 means that path MTU discovery is already turned-on by default.) What the correct way to deal with this? Should I just play around with net.inet.tcp.sendspace? _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
