Test & Verify

Need More Data

  • If you have a problem & I ask you for more data go here

AX.25 to TNC connection

  • Verify that the AX.25 config & TNC to radio & TNC to computer connections are working properly.
  • Receive tests

mheard

  • mheard is found in the ax25-tools package or tar ball
  • Display information about most recently heard AX.25 calls
mheard
man mheard

listen

  • listen is found in the ax25-apps package or tar ball
  • Monitor network AX.25 traffic heard by the system.
listen -a
man listen

E-mail client & MTA (postfix) config

  • Compose an e-mail with your e-mail client & send e-mail
  • A file should appear in the paclink-unix outbox waiting for a pending transport operation via wl2ktelnet, wl2kax25 or wl2kserial
ls -salt /usr/local/var/wl2k/outbox
  • Verify that the permissions in your wl2k directory are OK ie. user username and group mail
  • For example for user gunn and group mail:
     Directory of /usr/local/var/wl2k
  drwxrwsr-x    3 gunn     mail         4096 Nov  2  2013 ./
  drwxr-sr-x    4 root     staff        4096 Nov  2  2013 ../
  drwxrwsr-x    2 gunn     mail         4096 Dec  7  2013 outbox/
  -rw-------    1 gunn     mail        12288 Jan  5 14:55 mid.db
  • verify that user is in group mail by executing:
groups
  • or
id

wl2ktelnet test

  • wl2ktelnet will test your mail & paclink-unix config and does not touch your TNC or radio.
    • You must have an internet connection to make this work as it uses the telnet internet protocol
  • Compose a message addressed to your callsign, verify that a file appears in the outbox and send with telnet.
wl2ktelnet
man wl2ktelnet
  • Run the wl2ktelnet program again, you should receive the message you just composed to yourself.
    • Receiving mail addressed to yourself only works if the mail.wl2k program uses the '-m' argument.

wl2kax25 test

  • Repeat the above test but use the wl2kax25 program instead of wl2ktelnet.
    • This uses your radio and TNC rather than the internet.
  • locate a nearby RMS gateway by using mheard, listen or the Winlink Universal RMS Map
  • <someRMSGateway> will be a valid ham callsign with usually but not always having a sid of 10
    • ie. n7nix-10
  • <someDigitpeater> will be any alphanumberic restricted to 8 characters in length
    • ie. digi
    • digipeater callsigns are sometimes aliases & will not necessarily look like valid callsigns.
wl2kax25 -c <someRMSGateway>
# or
wl2kax25 -c <someRMSGateway> <someDigipeater>
man wl2kax25

Common Problems

Make sure user is in group mail
  • Type:
groups
Check permissions on the outbox file
  • Note if you ever send mail as root you will screw up the permissions. Type:
  • Example
ls -salt /usr/local/var/wl2k/outbox/
total 16
4 drwxrwsr-x 2 gunn mail 4096 Sep 21 16:48 .
4 -rw------- 1 gunn mail  214 Sep 21 16:48 V1IRQZ_N7NIX
4 drwxrwsr-x 3 gunn mail 4096 Sep 21 15:55 ..
4 -rw------- 1 gunn mail  196 Sep 21 15:55 H51W38_N7NIX
ls -salt /usr/local/var/wl2k/
total 20
4 drwxrwsr-x 2 gunn mail   4096 Sep 21 16:48 outbox
4 drwxrwsr-x 3 gunn mail   4096 Sep 21 15:55 .
8 -rw------- 1 gunn mail  12288 Sep 21 15:55 mid.db
4 drwxr-sr-x 4 root staff  4096 Jul  7 12:49 ..
Check /etc/postfix/transport file
  • Note hactar is the local machine & brox is a machine on my local net.
    • The last line is important
# cat transport
#
localhost      :
hactar       local:
hactar.localnet  local:
brox smtp:[brox.localnet]
brox.localnet smtp:[brox.localnet]
#
*         wl2k:localhost
Make sure you are addressing To: person with winlink.org
Make sure your /etc/postfix/master.cf entry is correct especially user
  • Example:
wl2k      unix  -       n       n       -       1      pipe
  flags=XFRhu user=gunn argv=/usr/local/libexec/mail.wl2k -m
Open 2 console windows for debugging
  • In one console window type:
tail -f /var/log/mail.log
  • In another console window type:
echo "test mail from command line" | mutt -s "Test12:56" n7nix@winlink.org
  • or using the mail program
# from command line or script
echo “This will go into the body of the mail” | mail -s '//WL2K cmd line test' -a "From: yourcallsign@winlink.org" -a "Reply-To: yourcallsign@winlink.org" some_regular_email_address
  • Link to set up mutt or mail
  • Look for problems in the /var/log/mail.log file
