Tue 24 Jun 2008 08:08:09 PM UTC, comment #4: The problem is no longer there on Fedora 9. It still uses the TI-RPC libs. I guess there was a bug in the rpcbind that did not allow requests to be made through the loopback interface. See also RedHat bug 358621 https://bugzilla.redhat.com/show_bug.cgi?id=358621	Robert de Vries <rhdv>
Tue 25 Mar 2008 03:56:41 PM UTC, comment #3: I do add a temporary fix which is to start rpcbind service in "insecure mode" if you want to do that you may cp the attached rpcbind file to /etc/sysconfig/rpcbind this works on Fedora 7 (file #15332)	Eric NOULARD <erk>
Thu 30 Aug 2007 01:39:34 PM UTC, comment #2: Heres comes some more links about TI-RPC and RPCBind: http://sourceforge.net/projects/rpcbind/ http://sourceforge.net/projects/libtirpc/ http://nfsv4.bullopensource.org	Eric NOULARD <erk>
Thu 30 Aug 2007 01:34:03 PM UTC, comment #1: Ok I think I will understand to myself. The fact is Fedora 7 in the first linux distro I've crossed which use TI-RPC + RPCBind: http://nfsv4.bullopensource.org/doc/tirpc_rpcbind.php rpcbind is a drop-in replacement for "classical" rpc portmapper. It may be worth detecting if we are on a system which use TI-RPC or "classical ONC-RPC" and effectively use TI-RPC API instead of older SunRPC/ONCRPC. but in the meantime the only acceptable solution is to start rpcbind with the "-i" insecure option. I "unassign" the bug since I'm not sure to have time to handle it.	Eric NOULARD <erk>
Thu 30 Aug 2007 11:56:36 AM UTC, original submission: On a Fedora 7 box I am unable to start the properly compiled stub server and I get the following error: $ tsp_stub_server #=====================================================================# # Launching <StubbedServer> for generation of 1000 Symbols at 100.000000 Hz #=====================================================================# Cannot register service: RPC: Authentication error; why = Client credential too weak ERROR\|\|/udd/deri/enoulard/workspace/tsp/src/core/rpc/tsp_server.c##TSP_rpc_run##277: RPC server unable to register ProgId=31230010 ERROR\|\|/udd/deri/enoulard/workspace/tsp/src/core/ctrl/tsp_request_handler.c##TSP_provider_rqh_manager_refresh##218: Request handler # 0 could not start properly #=== End ===# I am able to start stub server when logged as root. And I am able to start it if the rpcbind daemon/service is started using the "Insecure" mode. As far as I understand, this would mean that we try to use the rpc portmapper service through an @IP which is not 127.0.0.1.	Eric NOULARD <erk>
