[Dxspider-support] How to configure your dxspider to update automatically.

[Danilo Brelih]

Keith thanks for sharing.
It might not be a bad idea to recall for better transparency of new DXspider 
updates also to turn on the "DXSpider Channel" on Telegram. Routine for sending 
a message via Telegram bot is part of the Kin's check_build script and needs to 
be enabled in Local.pm and DXVars.pm.

> # Force update Kin's update utilities each night prior to update
> 30 22 * * * spawn('cd /spider/local_cmd; wget -q 
> https://raw.githubusercontent.com/EA3CV/dxspider_info/main/check_build.pl -O 
> /spider/local_cmd/check_build.pl')
> 32 22 * * * spawn('cd /spider/local_cmd; wget -q 
> https://raw.githubusercontent.com/EA3CV/dxspider_info/main/undo_newbuild.pl -O 
> /spider/local_cmd/undo_newbuild.pl')
> 35 22 * * * run_cmd('load/cmd')
>
> # Check for updates on weekdays at 22:40 and 01:07, avoiding contest times at 
> weekends
> 40 22 * * 1,2,3,4,5 run_cmd("check_build Y 5")
> 07 01 * * 1,2,3,4,5 run_cmd("check_build Y 5")
>
> You may want to adjust the times slightly because apart from anything else, we 
> don’t want every node updating at exactly the same time when there’s an update.
>
> I have my crontab set to local time rather than UTC.
>
> This is using the excellent script provided by Kin.  At 22:30 and 22:32, it 
> grabs a fresh copy of the two scripts from Github in case Kin has made any 
> changes.  There are two scripts, check_build which does the actual update and 
> undo_newbuild which can roll back if needed.
>
> Then at 22:40 each weekday night and 01:07 each weekday morning, the script 
> runs which checks for a dxspider update.  If there is one available, it first 
> takes a backup before updating.  Up to five backups will be kept.  The node is 
> only restarted if an update is applied and it’s only down for a fraction of a 
> second.
>
> I hope this is useful.
