Alright, maybe some progress.
the strace on in.rlogind (strace -pf <xinetd PID>) shows the hangup on
connect(0, {sa_family=AF_INET sin_port=htons(113) sin_addr(DIP)},
128) - typed, so probably not perfect.
I think this may be associated with ident issue. As I recompiled
xinet without libwrap, I assume the request is coming from in.rlogind.
Do the 2.4 instructions apply to RHEL5.2? Any other advice?
Thanks.
