My ssh sessions are "dumb terminals" now

[freenas_user47]

I haven't changed any settings and now every time I log into my server ( with root) I get "this is a dumb terminal" so I can't VI files.

It was working correctly this weekend and a few days ago it just stopped. I'm using the newest version of Putty and I've rebooted the machine (I've actually applied an update since then)


What happened and how can I fix it?

But if the terminal type seems wrong, or you see a message indicating that you are on a“dumb terminal”[3], you need to tell the Unix system what kind of terminal you are reallyemulating. The command to do so is

setenv TERM xxxx

where xxxx is the kind of terminal (e.g,setenv TERM vt100).

thanks for the suggestio, but still no go.

Here is a snippet of what I get when I log in.

Code:

Using username "root".
root@192.168.1.98's password:

Welcome to FreeNAS
csh: Cannot open /etc/termcap.
csh: using dumb terminal settings.
[root@freenas] ~#

I then tried a recommendation on the internet, and got

Code:

root@freenas] /etc# setenv TERM xterm
csh: Cannot open /etc/termcap.
csh: using dumb terminal settings.

what else is interesting, is that I lost ssh access to my jails.


after more investigation, I have more errors on my machine

Code:

[root@freenas] /etc# zpool status -v freenas-boot
  pool: freenas-boot
 state: DEGRADED
status: One or more devices has experienced an error resulting in data
		corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
		entire pool from backup.

		//usr/share/misc/termcap
		//usr/share/misc/termcap.db
[root@freenas] /etc#

seems to be the root of my issue, question is, where do i go from here.

That's easy. Backup config from GUI. Install FreeNAS to new USB. Restore config.

so my USB is bad? I just bought this thing, it lasted about 2 months. Are there recommended USBs?

Lucky it was only trivial files.

Suggest using two usbs in a mirror.

I use sandisk cruiser fit 16GB USBs
