Hello, if you connect a TNC via serial interface, you use the userspace kissattach program to bind the kernel-serial-interface to the kernel-kiss-driver (and behind, the kernel-ax25 stack). kissattach does not make more than tying together the filedescriptors the kernel serial/kiss stacks. After that, Userspace programs / libraries are not involved anymore (kissattach only links the fd to the kernel and does not do any read()/write()-operations).
Thus, it's a kernel-ax25 problem. I hope, Ralf dl5rb could tell more about. I remember we've observed that (or something comparable like that) years ago (at db0fhn, iirc on debian squeeze), where packets sent out of order and / or duplicated. I also have seen datagram packets (UI) with a payload size larger than 256 bytes. At db0fhn, we stopped IP-Mode-DG for various reasons. Some information about the described problem is missing: Do you use IP-Mode-VC (IP over connected-AX.25) or IP-Mode-DG (IP over UI-Frames)? Also, it would help for debuging, to get your configuration of /proc/sys/net/ax25/<ifname>/* vy 73, - Thomas dl9sau -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
