Description

I use a remote dir using "Shell link" (via ssh). If the connection was resetted by peer (e.g. adsl disconnect and reconnect with new ip address) changing the remote director fails instead of reconnecting. mc knows my password already, so it could reconnect and shoudl do that. Selecting "Rescan" fails also :(
Reconnect via "Shell link" also fails. Only way is to close mc and start again from new.

Replying to crissi:

Did you try to decrease the VFS timeout (menu Options->Virtual FS) or free VFS forced (menu Command->Active VFS list)?

No but its set to 60s. But it fails also after this time (e.g. several hours)

I don't think it's possible to implement this, because actually mc doesn't know the password (remember, we are talking about FISH, not FTP here). However, rescan is probably to be fixed...

I use RSA keys instead, so Midnight Commander has no idea about any passwords at all, but the issue is still there. It first opens the connection to the remote server just fine, but after it gets disconnected for any reason, the only way to connect again is to restart Midnight Commander, otherwise it just shows "Can't open ssh://... folder" or something like this. Refer to #3249.

Hello,

this seems like a major "usage blocker" for using FTP in MC on a regular basis. Why MC cannot make the same "connect action" when it gets the aforementioned connection error (something that other FTP clients normally do)? What exactly is the issue which blocks this fix ("FISH" is not a satisfactory answer to me ;))?

Still happening (ssh vfs with linux openssh server on the remote side).

Anyway I've noticed that if the remote ssh server comes up again "quite soon" (I've tested 10-20 seconds), mc works as intended (no bug), otherwise (if the remote stays down for some longer time, e.g. some minutes) the bug happens.

I thought this was related to "VFS timeout (menu Options->Virtual FS)", I had the default value: 60s, so I tried increasing it, but it didn't help.

So I guess some other kind of timeout is involved.

Also, I tried the same with FTP instead of ssh, but I could't reproduce the bug: just pressing Ctrl-R re-establishes the FTP connection even after the remote FTP server has been down for a long time.
