openssh bugs - Sep 2007 - [Bug 1359] New: keyboard repeats when somebody logins as root through ssh

http://bugzilla.mindrot.org/show_bug.cgi?id=1359

           Summary: keyboard repeats when somebody logins as root through
                    ssh
           Product: Portable OpenSSH
           Version: 4.7p1
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ssh
        AssignedTo: bitbucket at mindrot.org
        ReportedBy: pacho at condmat1.ciencias.uniovi.es


If somebody connects to my system using ssh and logins as root (and
sometimes also as user) keyboard will repeat until user switch to
console and comes back to X.

This occurs on all my gentoo systems with openssh-4.5_p1, 4.6_p1 and
4.7_p1

Thanks a lot

What do you mean by "repeats"?  The same key appears multiple times
when you press it once, or the keystrokes are echoed even when they
should not be (eg while entering a password)?

Do you have PAM enabled and if so, what modules do you have in the sshd
stack?  If you do have it enabled, do you see the same behaviour with
"UsePAM no" in sshd_config.

Can you reproduce the problem with a vanilla OpenSSH 4.7p1 from
openssh.com without any Gentoo modifications?  (I have no idea what, if
anything, Gentoo changes.)

When anybody logins as root, keyboard starts to fail in X, sometimes,
if I press a key, it is repeated:
llllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllsssssssssssssssssssssssssssssss
...

until I switch to a console and come back to X. But, for example now,
when I was trying with openssh without pam, keyboard simply cannot
write anything but it works, because I can switch to a console and come
back to X also (Ctrl+Alt+F2 -> Ctrl+Alt+F7).

I get the same problem with and without pam enabled

My gentoo build only has the following modified:

1. After unpacking sources it runs:
        sed -i \
                -e
'/_PATH_XAUTH/s:/usr/X11R6/bin/xauth:/usr/bin/xauth:' \
                pathnames.h || die

        sed -i "s:-lcrypto:$(pkg-config --libs openssl):"
configure{,.ac} || die

2. Configure is run with the following options:

$ ./configure --prefix=/usr --host=x86_64-pc-linux-gnu
--mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share
--sysconfdir=/etc --localstatedir=/var/lib --with-ldflags--disable-strip
--sysconfdir=/etc/ssh --libexecdir=/usr/lib64/misc
--datadir=/usr/share/openssh --disable-suid-ssh
--with-privsep-path=/var/empty --with-privsep-user=sshd
--with-md5-passwords --without-ldap --without-libedit
--without-kerberos5 --with-tcp-wrappers --without-selinux
--without-skey --without-opensc --with-pam --libdir=/usr/lib64
--build=x86_64-pc-linux-gnu

3. After installing:

$ chmod 600 /etc/ssh/sshd_config

If you want, I can upload some config files...

Thanks a lot :-)

I attach a small video showing the problem, keyboard stops when I go to
console 1 and come back to X:
