There appears to be a problem with sending 0-length (UDP) datagrams. I have a little UDP server running on port 1392, and when I execute the following client code the server does not receive anything. However if I change it to data="x", the server receives it just fine. EM::run { conn = EM::open_datagram_socket( "", 0 ) data = "...

Hi, Looking at some udp stuff on snv_57, and I noticed that mib:::udpInDatagrams no longer exists, has this been superceded by mib:::udpHCInDatagrams? From my understanding they represent the same counter, but I''m asking in case this is a bug. I noticed that there is still a reference to udpInDatagrams in the DTrace testsuite. - Fintan

Hi guys, I'm having a little problem I would ask your help. I have followed the log of my samba (log.nmbd) and several times I see the message: process_dgram: ignoring malformed3 (datasize = X, len = Y, off = Z) datagram packet sent to name DOMAIN <00> from IP XXX,XXX,XXX,XXX Is there any way to fix this problem? I'm using Samba 3.5.6 integrated with LDAP server on a Debian Lenny 5.0.8. Thanks Daniel

...ets consumed by the server. Eventually over time this drives the client's remote window count to go to zero. As an aside the remote window count has to be exactly 0 for the stall to occur. Initially the following line of code in channel_output_poll that decrements the remote window count for datagram channels looked suspicious: c->remote_window -= dlen + 4; However, the code that updates Channel.local_window and Channel.local_consumed for a datagram channel also includes the +4 in the calculation. Does anybody know why the datagram calculation includes a +4? Anybody know what would cause...
