I have a very obscure problem with the w key on my new server.
If I am logged directly into the system console there is no problem. If I ssh into the machine the w key just causes the machine I am logged in from to beep every time I press it. according to dump keys "keycode 17 = w", which is correct.
if I start an xterm from the ssh session the same happens.
I have tried it from 3 different machines and exactly the same happens from each of them.
If I run strace on the client ssh process I get this output for pressing q:
| Code: |
) = 1 (in [4])
read(4, "q", 16384) = 1
select(7, [3 4], [3], NULL, NULL) = 1 (out [3])
write(3, "E\315\32UK:u\315\256e\325\221\330\322\327\34R\264\300i"..., 48) = 48
select(7, [3 4], [], NULL, NULL) = 1 (in [3])
read(3, "\227\210\341u~\226\272l\37\244o_\236\273u\204TP\362\253"..., 8192) = 48
select(7, [3 4], [5], NULL, NULL) = 1 (out [5])
write(5, "q", 1) = 1
select(7, [3 4], [], NULL, NULL

if I then press w I get this:
| Code: |
) = 1 (in [4])
read(4, "w", 16384) = 1
select(7, [3 4], [3], NULL, NULL) = 1 (out [3])
write(3, "\35\34t\212J\300\223s\0\3008\234\321\351h\16F}\223r\225"..., 48) = 48
select(7, [3 4], [], NULL, NULL) = 1 (in [3])
read(3, "\272B\346\250\t}\232UMmL\375\354\306\316\316Q+K.\353$\4"..., 8192) = 48
select(7, [3 4], [5], NULL, NULL) = 1 (out [5])
write(5, "\7", 1) = 1
select(7, [3 4], [], NULL, NULL

Capital W works fine, as do all the other keys.
Does anyone have any suggestions because I have no idea where to start on this one.

Does this just happen in bash, or in every application?
Check your stty settings; I have | Code: | stty -a
speed 38400 baud; rows 42; columns 127; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; start = ^Q; stop = ^S; susp = ^Z;
rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0;
-parenb -parodd cs8 -hupcl -cstopb cread -clocal -crtscts
-ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl -ixon -ixoff -iuclc -ixany -imaxbel
opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0
isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke

If 'erase', 'kill', or 'werase' is set to 'w', you'd get the symptoms you describe. (They should be control characters).
Another possibility is that bash is in vi mode [set -o vi], although that's kinda hard to miss, since many other keystrokes would behave, um, oddly (that is, if you don't realize it's in vi mode).
There may also be ssh settings; check the ssh and ssh_conf man pages.
This may be happening just with ssh, incidentally, because the way the tty defaults are set changes (it tries to copy settings from the remote host). Also check your /etc/profile, ~/.bash_login, and ~/.bashrc for stty commands. |
