RedHat 7.3 and AX25

RedHat 7.3 and AX25

[Stewart Wilkinson]

Hi,

I seem to have a problem using kissattach with the 2.4.18-3 kernel. I have
rebuilt a kernel with MKISS support on (ie: CONFIG_MKISS=y in .config),
yet when I try to run kissattach I get:

kissattach: Error setting line discipline: TIOCSETD: Invalid argument
Are you sure you have enabled MKISS support in the kernel
or, if you made it a module, that the module is loaded?

Any Idea's ??

Hi Stewart

I had exactly the same problem. It seemed to ignore the request to compile MKISS into the kernel.

When I made it a module and loaded it manually, this solved the problem. 

Perhaps someone knows a bit more and can say whether this is a known bug, whether there is a fix, or whether we are both doing something wrong.

Thanks

Roger

I've noticed with Redhat 2.4.18 kernel source that the config file has-
CONFIG_HAMRADIO=m
I would have thought that it should be either y or n and is just there to say 
whether to skip over the ax25 stuff or not. It looks odd with "make xconfig" 
and I'm sure I had similar problems until I noticed it and changed it to y.

Option in kernel compilation

[Vivi Kusumo]

Hi all,

I have problem to choose <module> during make xconfig
# cd /usr/src/linux-2.4.19
# make xconfig
--- Amateur Radio support
<*>y  <>-  <>n   Amateur Radio support
--- Packet Radio protocols
<*>y  <>m  <>n   Amateur Radio AX.25 Level 2 protocol
--- AX.25 network device drivers
<>y  <*>m   <>n  Soundcard modem driver
<*>y  <>-  <>n  soundmodem support for Soundblaster
and compatible 
cards
 <>y  <>-  <*>n  soundmodem support for WSS and
Crystal cards
<*>y  <>-  <>n  soundmodem support for 1200 baud AFSK
modulation
 <>y  <>-  <*>n  soundmodem support for 2400 baud AFSK
modulation (7.3728MHz crystal)
 <>y  <>-  <*>n  soundmodem support for 2400 baud AFSK
modulation (8MHz crystal)
 <>y  <>-  <*>n  soundmodem support for 2666 baud AFSK
modulation
 <>y  <>-  <*>n  soundmodem support for 4800 baud
HAPN-1 modulation
 <>y  <>-  <*>n  soundmodem support for 4800 baud PSK
modulation
 <>y  <>-  <*>n  soundmodem support for 9600 baud FSK
G3RUH modulation

I can not choose/click module for "soundmodem support
for Soundblaster and compatible cards" and "soundmodem
support for 1200 baud AFSK modulation". I can only
click yes or no, I don't know why?

Thanks for any help.

Vivi

I think that is normal. You choose a module for the whole soundmodem
driver then choose what sound cards that module will support.

This won't work well without AX.25 also being in the kernel. BUT it is 
much much better to use KISS as a module (CONFIG_MKISS=m) instead.

mv .config .config.old
sed 's/CONFIG_MKISS=y/CONFIG_MKISS=m/' <.config.old >.config
make modules
make modules-install
make bzImage (only needed to rebuild kernel without mkiss in it)
...whatever steps you use to install new kernel 
...and update MBR (i.e. run lilo)

reboot

depmod -a

/sbin/modprobe ax25
/sbin/modprobe mkiss
kissattach ...

I would recommend building a kernel from generic 2.4.19 sources 
(www.us.kernel.org) rather than RedHat's kernel source rpm unless you need to 
use RedHat's patches for some non-standard reason. 2.4.19 has some fixes
for amateur radio.

I hope that helps,
