Chris,

I wasn't sure where to turn with this problem. I have successfully built a
8 node alpha cluster (using slackware of course!)

Everything is excellent except for one problem. I am unable to get the
tcpdump package working. Everytime I run tcpdump, I get a seg fault. I
tried rebuilding the packages from the source, but still, (no errors on
compiling) tcpdump seg faults. More speciafically, I am using hte iplog
daemon to monitoring connections to my cluster. (not sniffing :) I believe
that the only dependency that tcpdump has is the libpcap library....

executing ldd /usr/sbin/tcpdump on an intel machine yields:
root@box:~# ldd /usr/sbin/tcpdump
        libc.so.6 => /lib/libc.so.6 (0x40019000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

excuting ldd /usr/sbin/tcpdump on the alpha yields:
root@dec:~# ldd /usr/sbin/tcpdump
        libcrypto.so.0 => /usr/lib/libcrypto.so.0 (0x0000020000120000)
        libc.so.6.1 => /lib/libc.so.6.1 (0x0000020000254000)
        libdl.so.2.1 => /lib/libdl.so.2.1 (0x0000020000488000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x0000020000000000)

If you have any suggestions, please let me know. (I would also be willing
to give you an account on a machine 500au (21164) to help remidy this
problem...)
