Well, at least the tcp part of it, it seems, yep. The debugging I've done so far also seems to confirm that the problem is somewhere beyond the tcp code, but I don't have any real clue yet ... > Do you have any firewall rules? Any tc rules? ip6tables rules, yes, but none in the filter/OUTPUT chain (and policy ACCEPT, of course) and only counting rules in mangle/OUTPUT (using only user-defined chains and target RETURN, with policy ACCEPT, once again). So i'd wonder if that'd be the cause of the problem. BTW, other TCP/IPv6 (IRC) connections active at the same time work without problems - but each of them fails in that way now and then ... Well, all in all that probably doesn't help you much - but any hints as to how/where to further debug are welcome :-) Florian - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
