[Novalug] xinetd (solaris!) issues

[jecottrell3 at comcast.net]

YW. Other things you can do in wrapper scripts...set umask, change path, chroot, run a command via script -c and mail your-self/boss/customer the output, start/stop demons, add/delete user/groups, rotate log files, run backups, power off (but not on), the possibilities are endless (but not all of them are actually worth doing).

Sure beats looking thru tcpdump/wireshark/snoop dumps, altho the latter give you more info when you need it.

Great tip!!

Thanks to this I know that xinetd isn't doing what it should. I am 
launching xinet at a prompt with -d debug on. And I am not seeing 
anything (ie: amandad wrapped) launched. Well that might be an issue no? :-)
