G'day Folk,

My ax25 system (Debian system with Linpac and Soundcard modem) is broadcasting network Samba and Netbios UDP messages. Being almost illiterate with Linux could someone point me in the right direction to stop this.
I have checked the files in /etc/ax25/ but nothing seems to relate.

Where should I start looking?

www.samba.org perhaps. There's a Samba config file setting that tells it not to broadcast on certain ports. I can't remember what it is, sorry, but a Google search should find it. It's a common problem with AX.25 interfaces.

In the Configuration file there is a line "Interfaces"

i.e.

[snip]
# Date: 2003-11-04
[global]
workgroup = TASMANIA
Netbios Name = spirit
# Netbios Aliases = jukebox
os level = 65
log level = 3
security = share
time server = Yes
passdb backend = tdbsam guest

obey pam restrictions = yes

unix extensions = Yes
encrypt passwords = Yes
guest account = Nobody
map to guest = Bad User
printing = CUPS
printcap name = CUPS
socket options = SO_KEEPALIVE IPTOS_LOWDELAY TCP_NODELAY
# wins support = No
veto files = /*.eml/*.nws/riched20.dll/*.{*}/ hosts allow = 10.0.4.
wins support = yes
local master = yes
preferred master = yes
domain master = yes
interfaces = 10.0.4.162
^^^^^^^^^^^^^^^^^^^^
[snip]

Try that.

Regards
John

Try that.

If you use 10 series subnet, you have change "remote announce" into 10.x.x.255 If 192 series something like below.

; interfaces = 192.168.12.2/24 192.168.13.2/24
# *** merged from original smb.conf: ***
interfaces = 192.168.0.1/24

# Configure remote browse list synchronisation here # request announcement to, or browse list sync from:
# a specific host or from / to a whole subnet (see below)
; remote browse sync = 192.168.3.25 192.168.5.255
# Cause this host to announce itself to local subnets here
; remote announce = 192.168.1.255 192.168.2.44
# *** merged from original smb.conf: ***
remote announce = 192.168.0.255

You want to look at /etc/samba/samba.conf. Or what I have done is to use swat. I think it is installed with the samba packages, but I'm not sure. (Suse has it installed when you install webmin)
With webmin installed you go to "your-ip":10000 and log in as root. Then go to servers, samba, swat. Then when in swat go to global and under base options there is "interfaces" you need to set that for the IP of the interface you want samba to be on. Then hit commit changes, restart smbd and after that samba will only use the interface that has the IP addres that you put into that filed.

There at lest is the GUI way to do it for those who don't like command lines. Webmin is a wonderful thing ^_^
