There is plenty of non-GPL code out there showing how to do ax.25.

There is plenty of non-GPL code out there showing how to do ax.25. GB I've been using Phil Karnes' 'net' stuff for about 10 years now. It is the predecessor to the JNOS and TNOS code. It does ax25, net/rom and IP over a tnc with a kiss rom and runs in userland. I also hacked it to run with a BBS using IPC. The code is unencumbered and if you're interested, I'll put it out for download. I haven't compiled it since 2.x days, and I think it may need some tweeking to compile on 4.x. (I seem to recall getting some error messages the last time I tried). The BBS is available also. If you want it, I'll have to get it together to make a tarball. -Jim To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message
sk_buff on FreeBSD
Hi ! I have started proting some network protocols (ax.25 for ham) from linux, and I have come acrros structure called sk_buff. I was just wondering if someone tried to implement this on FreeBSD? It's seems that FreeBSD has mbuf structure which does the same thing as sk_buff on linux, but way things are done is quite different (as is the structure). So if someone can help, I would be very thankful... Andy To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message
Re: sk_buff on FreeBSD
you are right. mbufs are used for buffer management in the BSD stack. sk_buff as the linux equivalent . basically they are chains with control information and data. but i think linux assuming more memory allocated a large sk_buff and hence data and headers are contiguous. I remember Alan Cox giving some explanation for why it was this way. For more info you can search in google.For info on mbuf refer rich stevens TCP/IP vol 2 Quoting Aleksander Rozman [EMAIL PROTECTED]: Hi !
