Fragmentation

["Gérard Parat / F6FGZ" <f6fgz@free.fr>]

Hello,

I am wondering how to tweak mss/mtu/window/packet lenght etc ... to avoid
TCP/IP fragmentation for a 1200 bds link. I am trying to send 256 byte size
AX25 packet, here an example:

vhf: fm F6FGZ-4 to F6KBS-1 ctl I37^ pid=8(segment) len 255 22:05:44 First seg;
remain 1
IP: len 328 44.151.78.19->44.151.91.49 ihl 20 ttl 64 DF prot TCP
TCP: 46755->http Seq x74f3e657 Ack x86439001 ACK PSH Wnd 472 Data 213
0000  GET / HTTP/1.0M.Connection: Keep-AliveM.User-Agent: Mozilla/4.78
0040   [fr] (X11; U; Linux 2.4.18 i686)M.Host: f6bgr.ampr.orgM.Accept:
0080   image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, image/png,
00C0   */*M.Accept-Encoding
vhf: fm F6FGZ-4 to F6KBS-1 ctl I30^ pid=8(segment) len 76 22:05:45 remain 0
0000  : gzipM.Accept-Language: fr, en, zhM.Accept-Charset: iso-8859-1,
0040  *,utf-8M.M.

Data are splitted ...
