====== Test & Verify ======
===== Need More Data =====
  * If you have a problem & I ask you for more data go [[plu:test_verify:need_more_data | 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
<code bash>
mheard
man mheard
</code>

==== listen ====
  * //listen// is found in the ax25-apps package or tar ball
  * Monitor network AX.25 traffic heard by the system.
<code bash>
listen -a
man listen
</code>

===== E-mail client & MTA (postfix) config =====
  * Compose an e-mail with your e-mail client & send e-mail
    * [[plu:email_client_config | set up an e-mail client]]
  * A file should appear in the paclink-unix outbox waiting for a pending transport operation via wl2ktelnet, wl2kax25 or wl2kserial
<code bash>
ls -salt /usr/local/var/wl2k/outbox
</code>
  * Verify that the permissions in your wl2k directory are OK ie. user //username// and group //mail//
  * For example for user //gunn// and group //mail//:
<file>
     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
</file>
  * verify that user is in group //mail// by executing:
<code bash>
groups
</code>
  * or
<code bash>
id
</code>
===== Winlink connection test telnet/ax.25 =====
==== 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 [[wp>telnet]] internet protocol
  * Compose a message addressed to your callsign, verify that a file appears in the outbox and send with telnet.
<code bash>
wl2ktelnet
man wl2ktelnet
</code>
  * Run the wl2ktelnet program again, you should receive the message you just composed to yourself.
    * Receiving mail addressed to yourself only works if the [[plu:install_postfix#example_mastercf | 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 [[http://www.winlink.org/RMSMap | 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.
<code bash>
wl2kax25 -c <someRMSGateway>
# or
wl2kax25 -c <someRMSGateway> <someDigipeater>
man wl2kax25
</code>

====== Common Problems ======

== Make sure user is in group mail ==
  * Type:
<code bash>
groups
</code>

== Check permissions on the outbox file==
  *  Note if you ever send mail as root you will screw up the permissions.
    * Check your permissions in your outbox directory like this:
<code bash>
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
</code>
<code bash>
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 ..
</code>

== Check /etc/postfix/transport file ==
  * Note hactar is the local machine & brox is a machine on my local net.
    * The last line is important
<file>
# cat transport
#
localhost      :
hactar       local:
hactar.localnet  local:
brox smtp:[brox.localnet]
brox.localnet smtp:[brox.localnet]
#
*         wl2k:localhost
</file>

== Make sure you are addressing To: person with winlink.org ==

== Make sure your /etc/postfix/master.cf entry is correct especially user ==
  * Example:
<file>
wl2k      unix  -       n       n       -       1      pipe
  flags=XFRhu user=gunn argv=/usr/local/libexec/mail.wl2k -m
</file>

== Open 2 console windows for debugging ==
  * In one console window type:
<code bash>
tail -f /var/log/mail.log
</code>

  * In another console window type:

<code>
echo "test mail from command line" | mutt -s "Test12:56" n7nix@winlink.org
</code>
  * or using the //mail// program
<code bash>
# 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
</code>
  *  [[plu:email_client_config#mutt_and_mail | Link to set up]] //mutt// or //mail//
  * Look for problems in the /var/log/mail.log file
    * Open up another console window and do this:
<code bash>
tail -f /var/log/mail.log
</code>
