[Dx4win] DX4WIN networking

[Mel (ve2dc)]

Think about what you just wrote. OK I agree, it's a great idea if you never make mistakes. However, most of us do. DX4Win is an old design where networking was never considered. If networking is required there are plenty of loging programs that do this properly.

I do occasionally operate from a second location. I just keep separate logs and merge.

This is not true it can work perfect if the user doesn´t make mistakes .....

But first my answer to Glyn GW0ANA his question,
The way you expect it to work (updating all 3 instandly) is NOT supported without tricks or workarounds
But it can be done if the user is alert all the time.

I am NOT going to explain in detail how to setup all because there are always small risks and you need to spent money 
but I am running DX4WIN daily on 4 computers with only one log and never had any problem.
In short how to:

PC1 is the server (with SSD drive)
You need to buy for instance RealVNC or Radmin or you can use Teamviewer(free)
I have bought licenses for all 3 but prefer Radmin (screen delay is nearly 0 when using digital modes)
PC1 is started up with Radmin server (I only reboot this PC once in a month, no updates allowed) 
DX4WIN is started and running 24/24 (with dropbox for backup etc)

PC2
Here I start Radmin viewer and take over the screen from PC1   

PC3
Here I also start Radmin viewer and take over the screen from PC1      
  
PC4
PC5

You can type on any computer and all others are updating without delay.
After each qso I log I have the habit to use ALT-S (qso is written to disk and also dropbox is updated)


Without delay means that you must have reliable network and if you do it from remote location high speed internet

Very bad idea if the programs are open simultaneously.

Dropbox is FREE.

DX4WIN is not designed to share its log file. It keeps QSOs in memory and writes them to disk periodically, What this means is that if you log a QSO on one machine it won't be seen on the others. That means that QSOs will get lost (you log 3 QSOs on computer 'A', then go to computer 'B'. It doesn't see those QSOs, so when you write the log on computer 'B' they're lost).

Trying to do what you propose will quickly corrupt your log.
