How to switch tabs in MobaXterm

MobaXterm is a versatile terminal manager for Windows. Many Windows users are using Putty to connect to SSH on a remote machine or Git Bash when they want to use Git on Windows. MobaXterm can effectively replace these tools with more convenient experience.

One neat feature of many terminal applications on Linux is support for tabs (e.g. in Konsole). The question is how you can switch between tabs in MobaXterm just by using a keyboard.

The Default configuration of keyboard shortcuts is stored under menu Settings and option Keyboard shortcuts.

By default you can use:

Previous tab - Ctrl + Alt + LEFT
Next tab - Ctrl + Alt + RIGHT

I recommend chinging the configuration to match default keyboard shortcuts of Firefox or Google Chrome.

Previous tab - Ctrl + Page_UP
Next tab - Ctrl + Page_DOWN

Enjoy tabs. 🙂

Docker deploy DAB failed on Windows 10: service needs ingress network

Deploying application bundle to Docker Swarm (v17) is pretty straightforward. Simple command on Manager node:

docker deploy georgiktest --bundle-file .\georgiktest.dab

Unfortunately, it failed with message:

Loading bundle from .\georgiktest.dab
Creating network georgiktest_default
Creating service georgiktest_client
Creating service georgiktest_server
failed to create service georgiktest_server: Error response from daemon: rpc error: code = FailedPrecondition desc = service needs ingress network, but no ingress network is present

Solution that worked for me:

docker system prune
docker network create --ingress --driver overlay ingress

Thanks to cabloo for the solution.

Windows 10 displays different time after reboot from Linux

Using dual-boot Windows and Linux has several advantages. If one system fails to update, you can still work with the other one.

I experienced strange problem that Windows was always shifting the time about 2 hours after rebooting from Linux. One solution was to let Windows determine the time zone, but that worked until next reboot to Linux and back to Windows.

The solution that worked for me was to open regedit.exe and define following key as QWORD set to value 1:


Then reboot the machine to Linux and back to Windows and everything was ok. No more time shifts.

Thanks to Ailurus for the solution.
