Hi,
I have created a VNC session and after using it for sometime, it seems to
be "locked". It is configured to use one-time-passwords and I just can't
generate a new otp for access the session, vncpasswd hangs indefinitely
when trying to get a new password.
The session was created by the following command line:
/opt/TurboVNC/bin/Xvnc :13 -desktop X -httpd
/opt/TurboVNC/bin/../vnc/classes -auth /u/cnhu/.Xauthority -dontdisconnect
-geometry 3192x1046 -depth 24 -rfbwait 120000 -otpauth -rfbport 5913 -fp
/usr/share/X11/fonts/misc,/usr/share/X11/fonts/75dpi,/usr/share/X11/fonts/100dpi,/usr/share/X11/fonts/Type1,/usr/share/fonts/default/Type1
-co /usr/share/X11/rgb -deferupdate 1
When trying to launch a "vncpasswd -otp -display :13", I get no response
and eventually I have to press Ctrl+C. I have runned the vncpasswd command
line with strace and it seems to hang while trying to connect to Xvnc
through the "/tmp/.X11-unix/X13" socket (not sure if I've got it right).
Below you may check the end of the strace (until it hangs).
What may the problem be? The same happened twice in two different machines.
I have several other VNC sessions where this does not happen. Can I collect
information from anywhere else that could help me trying to figure out what
happened?
uname({sys="Linux", node="server03", ...}) = 0
socket(PF_FILE, SOCK_STREAM, 0) = 3
uname({sys="Linux", node="server03", ...}) = 0
uname({sys="Linux", node="server03", ...}) = 0
connect(3, {sa_family=AF_FILE, path="/tmp/.X11-unix/X13"...}, 20) = 0
uname({sys="Linux", node="server03", ...}) = 0
fcntl(3, F_SETFD, FD_CLOEXEC) = 0

{"\0\0", 2}, {"e\30\226A>\316@\17Y8\365+V\21\365\f", 16}], 4) = 48
fcntl(3, F_GETFL) = 0x2 (flags O_RDWR)
fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0
read(3, 0x7fff0b98aab0, 8) = -1 EAGAIN (Resource temporarily
