Can you give me a bzip2 binary network trace of the breakage something similar to tshark -w /tmp/macos.pcap host <macos_client> (Note: you might have to 'yum install wireshark' to get tshark Created attachment 157765 [details]
tshark -w macos-rpcbind.pcap host <ip-of-the-client>
OK, I finally had a chance to play with this. Let me know if capture
file is what you wanted...
Ok... it looks like Portmap CALLIT proc is broken... hmmm... I believe the problem is with the order of network ids in /etc/netconfig. Please switch the order of udp/tcp and udp6/tcp6 makeing udp/tcp first. Something similar to: --- /etc/netconfig.orig 2005-05-18 01:10:50.000000000 -0400 +++ /etc/netconfig 2007-07-24 09:45:40.000000000 -0400 @@ -10,10 +10,10 @@ # The <device> and <nametoaddr_libs> fields are always empty in this # implementation. # -udp6 tpi_clts v inet6 udp - - -tcp6 tpi_cots_ord v inet6 tcp - - udp tpi_clts v inet udp - - tcp tpi_cots_ord v inet tcp - - +udp6 tpi_clts v inet6 udp - - +tcp6 tpi_cots_ord v inet6 tcp - - rawip tpi_raw - inet - - - local tpi_cots_ord - loopback - - - unix tpi_cots_ord - loopback - - - Note You'll also have to restart rpcbind to have this change take effect I tried the change but it did not resolve the problem. I can see that things somehow behave differently but did not have time to do wire shark on it. Even after a reboot the problem persisted? When I rebooted my machine the exact same problem went away... I rebooted the machine. I think I will need to get network debug for you. However, this is a "production" machine and I can't this right away.. I confirm this bug too. I made the edit to /etc/netconfig from Comment #4 (Steve Dickson). Mac OS X 10.4 (Tiger) NIS client is still broken. This output is from rpcbind -d on F7 NIS server: pmap_rmtcall callit req for (100004, 2, 2, udp) from 192.168.2.116.192.237 : not found svc_maxfd now 8 polling for read on fd < 5 6 7 8 > poll returned read fds < 6 > pmap_rmtcall callit req for (100004, 2, 2, udp) from 192.168.2.116.192.237 : not found Please let me know what else I can do to help. My production FC5 box is dying. I need to move to my new F7 box soon! Best regards, Joe Kotran Joe, are the network interfaces configure to use ipv6? (In reply to comment #9) Steve, No, I am not using ipv6. Joe Kotran P.S. In 'production server' I mean my home multi-purpose server. We use RHEL 5 at work! Quick Update, I am looking for a mac0S machine so I can try and reproduce this... I am having the same problem with FC5 and FC8 ypbind on i386 clients trying to broadcast bind to a FC8 i386 ypserv. There is no ip6 anywhere in our network. I found another typo in the /etc/netconfig file Please try the following: --- /etc/netconfig.orig 2005-05-18 01:10:50.000000000 -0400 +++ /etc/netconfig 2007-07-24 09:45:40.000000000 -0400 @@ -10,10 +10,10 @@ # The <device> and <nametoaddr_libs> fields are always empty in this # implementation. # -udp6 tpi_clts v inet6 udp - - -tcp6 tpi_cots_ord v inet6 tcp - - udp tpi_clts v inet udp - - tcp tpi_cots_ord v inet tcp - - +udp6 tpi_clts v inet6 udp6 - - +tcp6 tpi_cots_ord v inet6 tcp6 - - rawip tpi_raw - inet - - - local tpi_cots_ord - loopback - - - unix tpi_cots_ord - loopback - - - I already had netconfig reordered.

Correcting recvfrom argument (fromlen)
I had the same problem with a Leopard client, tracked down the issue to an
incorrect argument to recvfrom.
Thank you for tracking this down!!! Fixed in rpcbind-0.1.4-13.fc9.src.rpm Fixed in rpcbind-0.1.4-13.fc8.src.rpm Which will be avaiable as soon as the build system starts working again.... (In reply to comment #18) > Fixed in rpcbind-0.1.4-13.fc9.src.rpm > Fixed in rpcbind-0.1.4-13.fc8.src.rpm I would very much like it to be fixed in fc7 as well! rpcbind-0.1.4-13.fc8 has been pushed to the Fedora 8 stable repository. If problems still persist, please make note of it in this bug report. |
