Multi-user access or shared config database

Multi-user access or shared config database   06 August 2021, 19:11

We are a small team of 5 network engineers, and this app gets used on a daily basis and has made a huge difference to how we troubleshoot problems.

One thing we have want to do is find a way that we can all use the app but work from the same database/config, so that when either of us adds a new hub/rack we can all see it, otherwise we can all end up working from out of date/sync databases.

We have tried running the portable version from a shared location, but this must only allow one instance to be opened as we had issues when multiple people tried to access it.

We also tried to install it on a server, then use RDP to login under our own username, but I think each user profile has its own database.

The only way we can think is for one of us to manage the adding/discovery of the network, and then export/import on each installation.

Obviously this app was designed for a single user only, but we just wondering if there was any way to achieve a multi-user config whereby we are all using the same database which any of us can access/update so we are always using the latest.

Thanks

This is indeed a challenging issue. In order to be multi-user friendly Port Mapper would need to handle concurrent additions, deletions and modifications to its data. Yet as you correctly mentioned, it's a single-user piece of software and adding that functionality is far from simple.

Instead, we can modify it so that when it's open, it will refuse to open more than one instance. Then you could place it in a shared folder and launch it as needed. An attempt to launch a second instance will result in a message like "This is already open by John Doe from computer JOHNPC". Will this help?

Thanks Andrew! Yes, that would be very useful, if not too much involved on your side!

We have updated Port Mapper, and now the portable version can be safely shared over network. The new build can be downloaded here.

Simply place it in a writable network folder, and it should handle concurrent access correctly. Opening the first instance will create a lock file. Opening a second instance will result in a message like shown below.

Please note that it must be launched from a shared folder. If it's launched locally, it will still allow more than one instance.
