That's a bug in libc (just like the "unknown server error" for non existing hosts). The same source works with older libraries. I'll reassign the bug to libc. > -chiark:~/mail> rsh myrddin -l iwj10 echo hi > hi > -chiark:~/mail> rsh myrddin -l root echo hi > Permission denied. That's correct, the rshd won't allow root logins. > -chiark:~/mail> rsh myrddin -l nonexistent echo hi > myrddin.chu.cam.ac.uk: Address already in use > -chiark:~/mail> rsh myrddin -l iwj10 dpkg -l '"net*"' > myrddin.chu.cam.ac.uk: Address already in use As you already said, it's the getopt bug + another libc4 bug.
