dovecot-v1.0-alpha build failed for Solaris 11 (OpenSolaris Nevada). The problematic line is in socket.c line 228. The fix should be to change SOL_TCP to IPPROTO_TCP found in netinet/in.h. This change should work universally on all platforms. Gary

...Everything else works like a charm. 2. With Outlook 2000 I can not connect to an Exchange server. I get immediately the message that the servers name can't be resolved. For sure it is resolvable, both by nameserver and /etc/hosts. On the console it says: fixme:winsock:convert_sockopt Unknown IPPROTO_TCP optname 0x8 err:winsock:WS_setsockopt Invalid level (6) or optname (8) This only happens if this server is available. If I give a resolvable but non reachable server name in the connection dialog of outlook, I also get the console output but Outlook seems to try for a long time to get a connection...

Seems like its the single byte thing... I tried adding: int flag = 1; if(setsockopt(fd, IPPROTO_TCP, TCP_NODELAY, &flag, sizeof(flag)) < 0) but did not have any effect. I also did the echo 1 > /proc/sys/net/ipv4/tcp_low_latency seems to have no effect also. Jerry

...that after executing some transactions an error comes related to EPROTONOSUP. The particular point where error comes looks like this- so_socket(PF_INET, SOCK_STREAM, -4, "", SOV_DEFAULT) Err#120 EPROTONOSUP . Above this error the normal behaviour was: so_socket(PF_INET, SOCK_STREAM, IPPROTO_TCP, "", SOV_DEFAULT) = 255 I found that this error comes when the protocol is not supported by the addres family. Could you please help me out on this about how to solve this one as how after executing for some time the protocol is not supported at all. Thanks & Regards uma ________...

Hi, I've a problem with rsync 2.6.2 and the daemon. I've installed it precisly as I did with 2.6.0 (I've tried before with 2.6.1 and was having the same problems as now with 2.6.2). When I try to a rsync --daemon command the rsync offcourse finishes, but in the log file it says 2004/05/04 21:15:10 [22369] rsyncd version 2.6.2 starting, listening on port 873 2004/05/04 21:15:10

Slightly RFC, as I need more time to investigate why Unix sockets appeared to degrade with this patch. But as TCP sockets (over loopback to localhost) and TLS sessions (regardless of underlying Unix or TCP) both showed improvements, this looks like a worthwhile series.

We just updated our configuratiosn to have multiple NIS servers, when we initiated a test of client failover, we were disapointed. It seemed that the only way to get a filaover was to /etc/init.d/ypbind restart.

Team I have a Dell PowerEdge R720xd, with the Broadcom NetXtreme bcm5720. I found the following thread: http://forums.freebsd.org/showthread.php?t=31769 I find I am unable to use the NIC's (there are 4 on the server). When we put a cable into it we get a "watchdog timeout -- resetting" error, and the machine will pause for 5 or so seconds. IP may or may not come up randomly.
