However, using the mkiss code for the kernel interface might remove the other problem, i.e. spattach falls into an uninterruptible sleep when killing it. I've checked it out, kissattach can be killed cleanly if no IP connection has been established before. 73 de Andreas -- Andreas Könsgen * DG3KQ * Aachen, Germany EMail: [EMAIL PROTECTED]

Re: 6pack: spattach won't die !
Hello, I've tested the problem on the weekend and could reconstruct it. I've discovered even another error -- when killing spattach after a TCP connection has been opened the kernel panics with the messages "killing interrupt handler" and "unable to kill the idle task". I think the problem is that the driver code which interfaces the kernel is very old -- it has been taken from the SLIP driver for 2.0.x kernels, later minor changes were done to get it compiled on 2.1.x kernels. But meanwhile so many things in the networking code have been changed that it is probably easier if I take the kernel interface code from the latest 2.2.x mkiss driver and replace/add the 6pack-specific routines. This will also be a good opportunity to fix the old documentation attached with the driver ... 73's de Andreas --- Andreas Könsgen * DG3KQ * Aachen, Germany EMail: [EMAIL PROTECTED]

I remember always killing spattach without 'downing' the interface. Maybe this might help... 73's.

The W flag means there are no pages of the program resident in the memory. The program itself has been killed and removed by the kill command.. The system call is still alive, but it hangs. There is no way to remove this entry except for rebooting the system. To find out what spattach does when hanging, start it with the line: strace spattach The strace command prints any system call used by spattach on the screen. 73 de Andreas -- Andreas Könsgen * DG3KQ * Aachen, Germnay * EMail: [EMAIL PROTECTED]

6pack: spattach won't die !
Hi everybody, I moved from kiss to 6pack in my TNC EPROMS, and started to use the 6pack driver in 2.2 kernels and spattach, the modified version of kissattach as explained in the README. I found that (as I espected) all ax25 connections now are working better, so I want to keep these settings. When I try to release the 6pack connection on the serial port something strange happens: ifconfig sp0 down > ok, the interface gets [NO FLAG] killall spattach --> trouble. killall -KILL spattach ---> same trouble. The 'spattach' process stucks in state 'DW' ; reboot needed. What should I do? IZ0BBZ - Stefano Corti Internet mail: [EMAIL PROTECTED] AX25 mail: [EMAIL PROTECTED]
