Top Forums Programming Fetch "my" IP address in HPUX 10.20 Post 8010 by Perderabo on Thursday 4th of October 2001 03:22:40 PM

Um, ttys do not have ip addresses.

I think you want the foreign address where the connection originated from? That's hard. The information is in another process. You would need root authority to poke around in /dev/kmem for the answer. The freeware program lsof can do this. You can build a tool around that. HP-UX makes an attempt to record this in utmp. Another possibility is to build something around "who -R am i" (hp-ux specific).

Either way I see a shell script around lsof or who that outputs the ip address. Then you would invoke the script via popen(3) to read the result.

MAKEDEV(8)						      System Manager's Manual							MAKEDEV(8)

NAME
makedev - make system special files SYNOPSIS
/dev/MAKEDEV device... DESCRIPTION
MAKEDEV is a shell script normally used to install special files. It resides in the /dev directory, as this is the normal location of spe- cial files. Arguments to MAKEDEV are usually of the form device-name? where device-name is one of the supported devices listed in section 4 of the manual and ``?'' is a logical unit number (0-9). A few special arguments create assorted collections of devices and are listed below. std Create the standard devices for the system; e.g. /dev/console, /dev/tty. The VAX-11/780 console floppy device, /dev/floppy, and VAX-11/750 and VAX-11/730 console cassette device(s), /dev/tu?, are also created with this entry. local Create those devices specific to the local site. This request causes the shell file /dev/MAKEDEV.local to be executed. Site spe- cific commands, such as those used to setup dialup lines as ``ttyd?'' should be included in this file. Since all devices are created using mknod(8), this shell script is useful only to the super-user. DIAGNOSTICS
Either self-explanatory, or generated by one of the programs called from the script. Use ``sh -x MAKEDEV'' in case of trouble. SEE ALSO
