Backspace does not work in SSH session

[0xc0fed00d]

When I'm pressing the backspace key of my keyboard while connected to termux via openssh, instead of deleting text left of the cursor, it adds spaces. The left arrow key is not working also.

stty -a gives me the following output:

intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R;
werase = ^W; lnext = ^V; discard = ^O; min = 1; time = 0;

Ctrl+V Backspace also results in ^?. stty erase ^? didn't help.

I'm running termux on Android 7.1.1, OpenSSH_7.5p1.

Which terminal emulator do you use when connecting to Termux over openssh?

[0xc0fed00d]

I'm using termite. I do not have any issues with other SSH connections.

What is your TERM environment variable when running under termite (as shown when running echo $TERM)?

Also, when ssh:ed into Termux using termite, could you:

1. Run apt install vtutils
2. Run vtshowkeys.
3. Press backspace on your keyboard.

and write the output here?

[0xc0fed00d]

$ echo $TERM
xterm-termite
$ ssh <phone-ip> -p 8022
-bash-4.4$ vtshowkeys
0177 127 0x7F Delete			^?

I hope that's sufficient.

Maybe this info is useful: after you ssh in, if you change the terminal type ($TERM) from xterm-termite to something like xterm-color256 or vt100 (ex. just write TERM=xterm-color256 and press enter) the keyboard will work ok.
