Hello Ole,
I'm about to port a STREAMS modul from Solaris 2.5 to Linux. It is implements an
acknowledged datagram
protocol using UDP.
To make myself familiar with LiS, I downloaded LiS-2.6 and your xti-0.4 and udp-0.2
packages. LiS in default config, compiles, installs and runs (strtst) without any
problems. xti and udp
compile with minor changes (I disabled struct t_opthdr, because already definded in
LiS/tpicommon.h)
I'm running SuSE 6.2 with a 2.2.10 kernel and gcc version 2.95.2 19991024 (release)
When I start udpechod I got the following syslog and error messages
Dec 28 12:52:39 brunhild modprobe: modprobe: Can't locate module char-major-30
brunhild:/usr/src/udp # ./udpechod
open("/dev/udp", O_RDWR, NULL): System error: No such device
crw-rw-rw- 1 root root 30, 39 Jul 23 01:05 /dev/udp
Any hint what I missed ?
