Synchronization of history when the ipython laptop and console are connected to the same core

Question

My ipython notebook running on a remote server, i.e.

 ipython notebook --profile=nbserver 

which I handle from my local machine. In addition, I ssh to a remote server from my machine and run ipython console (terminal) on this server. I found the following command to work well:

 ipython console --existing \ ~/.config/ipython/profile_nbserver/security/kernel-*.json 

Now I am connected to the same remote kernel from two different clients (lets call them browser and terminal ). Everything works well, except for one annoying detail:

1) in browser , I type a=1

2) in terminal , I type b=2

3) in both clients I can see both commands using %history . But when I want to iterate over the history (in terminal ) using Up , it only displays the commands that were entered into the terminal, (i b=2 ). Similarly, I cannot use a + PageDown in the terminal to go back in history and find a command starting with a .

From what I understand, my two clients use two separate history.sqlite history files. But why does %history show all the commands?

Question: Is there a way to configure using one history.sqlite for both clients?

I believe that easy access to history is crucial. Moreover, I consider the use of both terminals and the browser as optional, they both have compromises and are best combined.

You can set where the story is loaded, or by installing it on the terminal:

 ipython --HistoryManager.hist_file=$HOME/ipython_hist.sqlite 

or inside ipython configuration files:

 import os c.HistoryManager.hist_file=os.path.expanduser("~/ipython_hist.sqlite")
