Absolutely no TCP or UDP traffic shows in a tcpdump. The command ntpdate gives me this and nothing more: 15 Jan 10:06:59 ntpdate[22868]: poll(): nfound = 0, error: Success I was intially thinking that this was a glibc-i386 vs glibc-i686 problem, but it does not appears so after more research. I decided to run lsof, and get the following whenver ntpdate fails (doesn't send out any traffic at all when looking via tcpdump). Note the last line where I get "can't indentify protocol". [root@server]# lsof|grep ntpdate ntpdate 461 root cwd DIR 8,7 4096 144002 /root ntpdate 461 root rtd DIR 8,7 4096 2 / ntpdate 461 root txt REG 8,5 40460 128472 /usr/sbin/ntp date ntpdate 461 root mem REG 8,7 464409 65742 /lib/ld-2.2.4 .so ntpdate 461 root mem REG 8,5 44851 64355 /usr/lib/libc ap.so.1.10 ntpdate 461 root mem REG 8,7 5737154 64013 /lib/libc-2.2 .4.so ntpdate 461 root 0u CHR 136,3 5 /dev/pts/3 ntpdate 461 root 1u CHR 136,3 5 /dev/pts/3 ntpdate 461 root 2u CHR 136,3 5 /dev/pts/3 ntpdate 461 root 3u sock 0,0 175748304 can't identif y protocol I've checked the LSOF FAQ regarding this "can't indentify protocol", and I'm not any further ahead. I've not been able to reproduce this consistently, but when I shut down xinetd, ipchains, and enter "ALL:ALL" in hosts.allow, *eventually* (but not consistently especially as far as a timeframe), eventually ntpdate works as expected.
