That was me; glad to hear that it worked!
On a related note - it seems to me that there are a number of cases when
turning of TCP options via setting tcp_do_rfc1323 to 0 has been desirable.
Some Annex terminal servers crap out, some Netblazers have lots of lag with
VJ header compression, and now it seems that some versions of Linux also add
lots of delay when processing TCP packets with options in them.
Does anyone think it would be worthwhile to add a kernel option for this?
Or even better, a sysctl? I guess the MIB for this would be something
along the lines of:
This would make it configurable at run-time. It doesn't look like it would
be hard to do (the only think you would need to do would be to define a
tcp_sysctl function, but that looks fairly straightforward).
