This directory has a few utilities that will hopefully make it easier to trace
|
|
tty problems. Here's how to proceed:
|
|
|
|
1) test tty sanity on the local host (the one you're running zssh on).
|
|
- cd in this directory, type make to build the tools.
|
|
- run ./local_test. this script runs local_tty_test, which basically opens
|
|
a pty/tty pair on the local host, prints all 256 ascii chars on the tty,
|
|
and displays what comes out of the pty on stdout.
|
|
it also checks the other direction - writing to the pty, reading frome the
|
|
tty.
|
|
|
|
2) test tty sanity on the remote host (the one you're ssh'ing to).
|
|
same thing: copy the zssh source tree there, run configure, cd to the test/
|
|
directory, type make and run the script.
|
|
|
|
3) end to end test:
|
|
|
|
[local side]
|
|
- on the local host, cd to this directory (test/).
|
|
- connect to the remote side using zssh
|
|
|
|
[remote side, through zssh]
|
|
- cd to the test/ directory that got created in step 2)
|
|
- there should be a ttydump program in there. it roughly does a
|
|
cat > output.dump
|
|
(as the tty is put in raw mode however, it's immune to ^C and stuff, so
|
|
you'll have to kill it from another term)
|
|
run it:
|
|
|
|
$ ./ttydump
|
|
type ' kill 15627 ' to kill me
|
|
output file is output.dump
|
|
|
|
- now hit the zssh escape key, and type
|
|
|
|
zssh > hook ./ttyprint
|
|
|
|
that will send our reference output on the tty.
|
|
- now kill ttydump from another term on the remote host.
|
|
- check the output:
|
|
|
|
$ ./check_remote_test
|
|
remote tty test passed !
|
|
|
|
4) end to end test, the other way this time:
|
|
proceed likewise but with the remote side sending, and local side receiving:
|
|
|
|
[remote side, through zssh]
|
|
- it's a little bit more tricky because you need to setup the local side before
|
|
the remote side can send, so :
|
|
|
|
$ sleep 20 ; ./ttyprint
|
|
|
|
- hit zssh escape key
|
|
|
|
zssh > hook ./ttydump
|
|
|
|
[local side]
|
|
- wait 20 seconds, kill ttydump
|
|
- check the output:
|
|
|
|
$ ./check_remote_test
|
|
remote tty test passed !
