command line link/unlink

[w7efs]

How does one link/unlink to a given reflector from the command line, please.

We have a need to cron this activity so that various regular nets can be heard.

Thank you.

Link to REF001 C

Code: Select all

sudo pistar-link ref001_c

Unlink

Code: Select all

sudo pistar-link unlink

Here is the full output from the command:

Code: Select all

pi-star@pi-star(ro):~$ sudo pistar-link
To unlink from any connected reflector, use: pistar-link unlink
To link to REF000 A for example, use: pistar-link ref000_a

If you need to make a reflector FIXED so that users cannot unlink,
for schedulling connections via CRON for example you can use the
the following: pistar-link ref000_a fixed
Should you wish to Un-Fix a reflector, relink to the same reflector
without the fixed flag, such as: pistar-link ref000_a

Hope that helps!

Perfect, Andy, thank you.

This is awesome! I had no idea. Thank you.

Somehow the command seems to have gotten broken. While linked to a reflector:

# pistar-link unlink
remotecontrold: no address, port, or password is set

In /etc/ircddbgateway, remoteEnabled=1 with an assigned port and password. Permissions on the files look correct:

# ls -l $(which pistar-link remotecontrold)
-r-xr-xr-x 1 root bin 869036 Aug 2 2016 /usr/local/bin/remotecontrold
-rwxr-xr-x 1 root staff 1823 Mar 7 2018 /usr/local/sbin/pistar-link

... yet we're unable to unlink from the startup reflector or link to any other, using either the command line or the Admin web page. Any suggestions, please?

That date stamp for pistar-link may be of concern...

Code: Select all

pi-star@pi-star-3b(ro):~$ ls -l $(which pistar-link remotecontrol remotecontrold)
-r-xr-xr-x 1 root bin   2354276 Aug  2  2016 /usr/local/bin/remotecontrol
-r-xr-xr-x 1 root bin    869036 Aug  2  2016 /usr/local/bin/remotecontrold
-rwxr-xr-x 1 root staff    1823 Jul 13 13:59 /usr/local/sbin/pistar-link
pi-star@pi-star-3b(ro):~$

... though the size looks the same...

AF6VN thank you much, yes, ours is outdated relative to yours, despite the daily cron update and a manual pistar-{update,upgrade} since your reply. Here's the text of our pistar-link, and does that agree with yours, please:

Well, the actual shell script looks similar, but the opening comments are different... Or you failed to copy the entire script.

Thanks for your assistance. I restored from a backup and all is well again.

HI, for the not so savvy Linux guy (me). How do a write a CRON to do the following:

Link to 24 C on startup (that was easy)
Monday at 19:59 unlink 24 C
Monday at 20:00 link 24 A
Monday at 20:59 unlink 24 A
Monday at 21:00 link 24 C

Examples would be welcome, thank you
