[Giorgos Keramidas, 2003-03-31] | If everyone else supports underscores (I've only tested Solaris and | Linux 2.4.20), then perhaps, just for the sake of interoperability | with other systems, we should too. Just some data points (my opinion on this matter is irrelevant): In addition to Linux 2.4, Windows XP and Solaris 8 (as reported by DES), all of the following OSes allow (and, in some cases, have been allowing for quite a while:-) underscores: # HP-UX 10 $ uname -a HP-UX xxxxxxxx B.10.10 A 9000/712 unknown $ ping under_score.ofug.org -n 1 PING under_score.ofug.org: 64 byte packets 64 bytes from 127.0.0.1: icmp_seq=0. time=0. ms ----under_score.ofug.org PING Statistics---- 1 packets transmitted, 1 packets received, 0% packet loss round-trip (ms) min/avg/max = 0/0/0 # Digtal Unix/OSF1 4 (Tru64/OSF1 5.1 behaves differently: "Unknown host") $ uname -a OSF1 xxxxxxxx V4.0 1229 alpha alpha $ ping -c 1 under_score.ofug.org PING under_score.ofug.org (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=1 ms ----under_score.ofug.org PING Statistics---- 1 packets transmitted, 1 packets received, 0% packet loss round-trip (ms) min/avg/max = 1/1/1 ms # Ultrix 4.3 $ uname -a ULTRIX xxxxxxxx 4.3 0 VAX unknown $ /usr/etc/ping under_score.ofug.org under_score.ofug.org is alive # IRIX 5 $ uname -a IRIX xxxxxxxx 5.3 02091401 IP22 mips $ /usr/etc/ping -c 1 under_score.ofug.org PING under_score.ofug.org (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=255 time=0 ms ----under_score.ofug.org PING Statistics---- 1 packets transmitted, 1 packets received, 0% packet loss round-trip min/avg/max = 0/0/0 ms # Solaris 2.6/SPARC $ uname -a SunOS xxxxxxxx 5.6 Generic_105181-29 sun4u sparc $ ping under_score.ofug.org under_score.ofug.org is alive This probably only goes to show that the sanity checks were absent in these releases, not that it was a deliberate decision to allow underscores. -- Per Kristian Hove Dept. of Mathematical Sciences Norwegian University of Science and Technology
