I had some problems getting the flexnet destinations in uronode. Xnet node is running with various flexnet links. Now I also want uronode to know these flexnet destinations. There appears to be a small secret in the “prompt” that flexd expects. I had a prompt “pi1lap ==>” That is not what flexd expected. Flexd expects a prompt “=>” So now I had to adjust the Xnet prompt to the expectations of flexd. (Tnx Brian n1uro for the hint)
Maybe the “pi1lap =>” prompt will work, I have to test that

There is also something with the buffer size of flexd. See the README.flexd in the source dir.

root@gw:/etc/ax25# cat /usr/local/src/uronode-2.8/README.flexd
If you find that your flexd isn't properly working, scroll down to line 120
where it says:
char  buffer[256], port[14], path[AX25_MAX_DIGIS*10]
and adjust the buffer per your neighbor's screens. The formula is:
2 data frames: 256
3 data frames: 512
4 data frames: 1024

Okay so how muts frames i have, let’s have a look

[3] fm PI1LAP-15 to PI1LAP ctl SABM+
[3] fm PI1LAP to PI1LAP-15 ctl UA-
[3] fm PI1LAP to PI1LAP-15 ctl I00^ pid F0 (211)
(X)net V1.39 Node PI1LAP

That are 2 frames. I had to set the buffer size to 256 and recompile flexd.c

int download_dest(char *gateway, char *fname)
{
  FILE *tmp;
  char buffer[256], port[14], path[AX25_MAX_DIGIS*10];

Also i have made a change to line 277. Also change to 256 buffer size

    if (FD_ISSET(s, &read_fd)) {
//      if ((n = read(s, buffer, 512)) == -1) break;
	if ((n = read(s, buffer, 256)) == -1) break;

Setup flexd.conf

# /etc/ax25/flexd.conf
# see man flexd.conf

# The callsign-ssid you wish to poll your flex neighbor with:

MyCall          pi1lap-15

# How often do we poll our flex neighbor (in seconds):

PollInterval    300

# The FlexNet node we're to poll:

FlexGate        pi1lap

The prompt for Xnet

root@gw:/etc/ax25# grep prompt /usr/local/xnet/AUTOEXEC.NET
my prompt =>

Let’s give it a try.

Yes, all looks okay.

The flexnet destinations are saved in “/usr/local/var/ax25/flex” on a debian wheezy system.
