Re: (connect to mta.xtra.co.nz[203.96.92.132]: Operation timed out)
AFAIK Xtra's MTA's don't handle mail for the telecom.co.nz domain so I guess your problem would be unrelated to any timeout issues with mta.xtra.co.nz At 13:10 9/10/2001, Lin Nah wrote:

Lin, just a thought: are you using Linux 2.4.x with TCP explicit congestion notification (IIRC that's what "ECN" stands for) enabled? Doesn't work with Telecom's network, AFAIK. On Tue, 9 Oct 2001, Ted Grenfell wrote:

Yes ECN is broken on a large number of sites around the internet, but 99% of them can be fixed by vendor patches and alike. When I used to find a place that was broken with ECN I used to email them, but it got too much trouble (too many places broken) so I turned off ECN on Linux. If its broken thru a router @ Telecom I have no idea. Thanks Craig Whitmore Orcon Internet http://www.orcon.net.nz

Well, the reason I asked Lin is because ECN is enabled by default in the kernel config, and I know from experience that if it is, you can't send mail to Telecom. It can be turned off with: sysctl -w net.ipv4.tcp_ecn = 0 -- Regards, Juha --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
sysctl -w net.ipv4.tcp_ecn = 0
enabled by default???? (Which Distro??) cat "0" > /proc/sys/net/ipv4/tcp_ecn (works as well) Thanks Craig Whitmore Orcon Internet http://www.orcon.net.nz --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

IIRC on the pukka kernels from kernel.org. RHL and Mandrake have it.
