I am running tensorflow code remotely on a ssh server. (e.g., ssh -X account@server.address)
On the remote server, it says You can navigate to http://0.0.0.0:6006.
In this case, how can I check tensorboard? How can I navigate the address of a remote machine? I tried to search, but there seems no useful information.
0.0.0.0 is the wildcard address. Thus, you can use any address for the purpose unless the system's firewall is implementig something more restrictive.
That said, let's assume that it is implementing firewall-based restrictions (if it weren't, you could just access http://server.address:6006/ -- but so could anyone else). In that case:
ssh -L 16006:127.0.0.1:6006 account@server.address
...and then refer to http://127.0.0.1:16006/ in a local browser.
