Hi All, I have done some more investigation on this and have reached to a conclusion that rpcd daemon running on port 135 is being contacted through UDP communication but somehow it is not able to receive it. netstat -a returs Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 localhost.localdo:32769 *:* LISTEN tcp 0 0 *:shell *:* LISTEN tcp 0 0 *:135 *:* LISTEN tcp 0 0 *:sunrpc *:* LISTEN tcp 0 0 *:x11 *:* LISTEN tcp 0 0 *:ftp *:* LISTEN tcp 0 0 *:ssh *:* LISTEN tcp 0 0 localhost.localdoma:ipp *:* LISTEN tcp 0 0 *:telnet *:* LISTEN tcp 0 0 localhost.localdom:smtp *:* LISTEN tcp 72 0 vmlctlx4.india.hp.c:135 nt12254.india.hp.c:1497 ESTABLISHED tcp 0 0 vmlctlx4.india.h:telnet nt1751.india.hp.co:3436 ESTABLISHED tcp 0 2 vmlctlx4.india.h:telnet nt1751.india.hp.co:3337 ESTABLISHED udp 65344 0 *:135 *:* udp 0 0 *:sunrpc *:* udp 0 0 *:631 *:* Active UNIX domain sockets (servers and established) Proto RefCnt Flags Type State I-Node Path unix 2 [ ACC ] STREAM LISTENING 1717 /dev/gpmctl unix 2 [ ACC ] STREAM LISTENING 1838 /tmp/.font-unix/fs7100 unix 2 [ ACC ] STREAM LISTENING 1962 /tmp/.X11-unix/X0 unix 9 [ ] DGRAM 1113 /dev/log unix 2 [ ACC ] STREAM LISTENING 1952 /tmp/.gdm_socket unix 3 [ ] STREAM CONNECTED 1992 /tmp/.X11-unix/X0 unix 3 [ ] STREAM CONNECTED 1991 unix 3 [ ] STREAM CONNECTED 1988 /tmp/.X11-unix/X0 unix 3 [ ] STREAM CONNECTED 1987 unix 3 [ ] STREAM CONNECTED 1972 /tmp/.font-unix/fs7100 unix 3 [ ] STREAM CONNECTED 1971 unix 3 [ ] STREAM CONNECTED 1974 /tmp/.X11-unix/X0 unix 3 [ ] STREAM CONNECTED 1965 unix 2 [ ] DGRAM 1860 unix 2 [ ] DGRAM 1728 unix 2 [ ] DGRAM 1693 unix 2 [ ] DGRAM 1679 unix 2 [ ] DGRAM 1563 unix 2 [ ] DGRAM 1323 unix 2 [ ] DGRAM 1122 cat /proc/net/udp returns sl local_address rem_address st tx_queue rx_queue tr tm->when retrnsmt uid timeout inode 7: 00000000:0087 00000000:0000 07 00000000:0000FF40 00:00000000 00000000 0 0 26555 2 c1391080 111: 00000000:006F 00000000:0000 07 00000000:00000000 00:00000000 00000000 0 0 1151 2 c1935060 119: 00000000:0277 00000000:0000 07 00000000:00000000 00:00000000 00000000 0 0 1809 2 cdcbc0c0 As you can see some bytes present in the UDP queue. I am not sure why rpcd listening is not able to get this. Any help would be appreciated. Thanks, Vaibhav Khanduja "Steven J. Yellin" <[email protected]> wrote: You are using the original RH9 kernel. I don't know how to deal with the problem you've partly described, but the first thing to try is getting all the updates, including the latest kernel, version 2.4.20-43.9.
