Maiko has been busy again to make some adjustments in Jnos. A friend of mine had asked if it was possible to save a Most Heard list. A few days later it was already done. Fantastic. It is also possible to leave the file ftpusers and use hashed passwords.

Read change.2.0m.1.txt for al the new options.

Save and Load ax25 Heard List

 The ax25 heard list can now be saved to a file or loaded (restored) from a file.

 Decided to also revamp the 'ax heard' command at the JNOS console, since there are
 now several commands available, all of which really should be categorized as being
 subcommands of 'ax heard' - so with this update, the new syntax is as follows :

     Usage : ax heard < show | dest > [<iface>]
             ax heard < save | load >

 The 'dest' and 'hearddest' commands are gone, absorbed by the above syntax.

 The heard data is kept in a new 'AxHeardFile' in the JNOS root directory.

 There are two files to update (ax25cmd.c and axheard.c), they have been added
 to the patch file noted further down (under the Password Management section),
 so if you're not interested in the password code, just extract the 2 files.

 Add '#define BACKUP_AXHEARD' to your config.h, then :

    rm ax25cmd.o axheard.o ; make


Jnos 2.0m run as NON-Root user

From version 2.0m it is possible to run Jnos as a NON-Root user.

The changelog from the website of Maiko.

a) create a new JNOS user and group


  b) change ownership of the entire JNOS runtime area

       chown -R jnos:jnos /jnos/rte

  c) as root user, configure a tunN interface, and just leave it there forever.

       ip tuntap add mode tun dev tun4

       ifconfig tun4 pointopoint mtu 1500 up

     WARNING : make sure you pick a number N that does not conflict with any
               other tun interfaces that might be running - OpenVPN comes to
               mind for example, some VM subsystems might use tun as well ?

   d) modify autoexec.nos, add an extra parameter to the 'attach tun' entry,
      and make sure to comment out the point to point ifconfig.

      So what was previously run as root, for example, below :

       attach tun tun0 1500 0

       shell ifconfig tun0 pointopoint mtu 1500 up

      will now just become a one line entry, below :

       attach tun tun0 1500 0 tun4

I have add some of the stuff in my /etc/rc.local file.

# Jnos
sysctl -w net.ipv4.ip_forward=1
ip tuntap add mode tun dev tun4
ifconfig tun4 pointopoint mtu 1500 up

# Put a "Proxy ARP" on the Linux Ethernet so that it can answer any
# querries for the JNOS addres
/usr/sbin/arp -i eth0 -Ds eth0 pub

This is what i have in the autoexec.nos

attach tun tun0 1500 0 tun4
ifconfig tun0 ipaddress
ifconfig tun0 netmask 0xfffffffc
ifconfig tun0 mtu 1500

Now you can run Jnos as a “normal” user.
