For me, without tooltalk datbase running, ttsession dangerously was hanging on kevent(2), hanging a whole X session. Also not good.
Here is how I got it working AKA quick ToolTalk troubleshooting guide.
All of this should apply to Linux and other OS's as well, only commands will
be different.
1. Exit X
2. Kill inetd (service inetd stop)
3. Kill rpcbind (service rpcbind stop)
4. Make sure no rpc.ttdbserver or rpc.cmsd or ttsession process is running
(ttsession needs to be killed with "kill -9" if hanging on kevent(2)).
5. "rpcinfo -p" should say:
# rpcinfo -p
rpcinfo: can't contact portmapper: RPC: Port mapper failure - RPC: Success
6. Make sure your hostname is in /etc/hosts:
# grep `hostname` /etc/hosts
127.0.0.1 localhost localhost.my.domain poniatowski
# hostname
poniatowski
#
7. Build ToolTalk example app:
% cd cdesktopenv-code/cde/examples/tt
% make -f Makefile.FreeBSD clean
rm -f broadcast broadcast.o
% make -f Makefile.FreeBSD
clang -c -O -g -I/usr/dt/include -I/usr/local/include broadcast.c
clang -o broadcast broadcast.o -L/usr/dt/lib -ltt -L/usr/local/lib -lXm
-L/usr/local/lib -lXt -lX11
8. Verify types.xdr:
% ls -l /etc/tt/types.xdr
-rw-r--r-- 1 root wheel 16084 Jul 28 21:23 /etc/tt/types.xdr
9. Verify inetd configuration:
% grep rpc /etc/inetd.conf | grep /usr/dt
cmsd/2-5 dgram rpc/udp4 wait root /usr/dt/bin/rpc.cmsd rpc.cmsd
ttdbserver/1 stream rpc/tcp4 wait root /usr/dt/bin/rpc.ttdbserver
/usr/dt/bin/rpc.ttdbserver
10. Start rpcbind (service rpcbind start)
11. rpcinfo -p should now say:
% rpcinfo -p
program vers proto port service
100000 4 tcp 111 rpcbind
100000 3 tcp 111 rpcbind
100000 2 tcp 111 rpcbind
100000 4 udp 111 rpcbind
100000 3 udp 111 rpcbind
100000 2 udp 111 rpcbind
100000 4 local 111 rpcbind
100000 3 local 111 rpcbind
100000 2 local 111 rpcbind
12. Start inetd (service inetd start)
13. rpcinfo -p should now say:
% rpcinfo -p
program vers proto port service
100000 4 tcp 111 rpcbind
100000 3 tcp 111 rpcbind
100000 2 tcp 111 rpcbind
100000 4 udp 111 rpcbind
100000 3 udp 111 rpcbind
100000 2 udp 111 rpcbind
100000 4 local 111 rpcbind
100000 3 local 111 rpcbind
100000 2 local 111 rpcbind
100068 2 udp 47699 cmsd
100068 3 udp 47699 cmsd
100068 4 udp 47699 cmsd
100068 5 udp 47699 cmsd
100083 1 tcp 43859 ttdbserver
cmsd (calendar daemon) and ttdbserver should be registered.
Their processes (rpc.cmsd rpc.ttdbserver) do not have to run at this point.
14. Start non-CDE X session (anything, the simplest the better, I am using dwm)
15. Verify there are no ToolTalk properties:
% xprop -root | grep TT_SESSION && echo "ToolTalk trash present" || echo "No
ToolTalk trash"
No ToolTalk trash
16. If you are troubleshooting again and there is some stale TT registration
(ttsession is not running)
remove the registrations using:
% xprop -root -remove _SUN_TT_SESSION
% xprop -root -remove TT_SESSION
% xprop -root | grep TT_SESSION && echo "ToolTalk trash present" || echo "No
ToolTalk trash"
No ToolTalk trash
%
17. STARTING TOOLTALK
% /usr/dt/bin/ttsession -s
%
15. Check properties:
% xprop -root TT_SESSION
TT_SESSION(STRING) = "01 66877 1342177279 1 1 169 127.0.0.1 4"
169 is UID of the user
66877 is a PID and should match:
% ps ax |grep ttsession | grep -v grep
66877 2 I 0:00,02 /usr/dt/bin/ttsession -s
1342177279 is the RPC service address.
16. Check rpcinfo -p:
% rpcinfo -p
program vers proto port service
100000 4 tcp 111 rpcbind
100000 3 tcp 111 rpcbind
100000 2 tcp 111 rpcbind
100000 4 udp 111 rpcbind
100000 3 udp 111 rpcbind
100000 2 udp 111 rpcbind
100000 4 local 111 rpcbind
100000 3 local 111 rpcbind
100000 2 local 111 rpcbind
100068 2 udp 47699 cmsd
100068 3 udp 47699 cmsd
100068 4 udp 47699 cmsd
100068 5 udp 47699 cmsd
100083 1 tcp 43859 ttdbserver
1342177279 4 tcp 29536
1342177279 1 tcp 29536
ttdbserver must be present - if it is not, check the /var/log/messages if it is
crashing
1342177279 should be the RPC service address from the ttsession
It should now listen on TCP port 29536:
% nc -v localhost 29536
nc: connect to localhost port 29536 (tcp) failed: Connection refused
Connection to localhost 29536 port [tcp/*] succeeded!
^C
If you have than two entries like 1342177279 (four, six)... this means
stale tooltalk sessions are registered with RPC.
Remove them with "rpcinfo -d" or better yet restart troubleshooting
- back to point 1.
17. At this point ttsession should be assumed healthy. Start "broadcast" to
verify:
% cd cdesktopenv-code/cde/examples/tt
% ./broadcast
A ToolTalk Sample 1 X11 window should open
If it does not pop up, or just hangs - something of the above is wrong.
There should be to sliders:
- "Send" with value 0
- "Received:" with value 0
and a button "Broadcast"
Shift "Send" to 5
Press "Broadcast"
"Send" and "Received" should jump to 6
Congratulations! ToolTalk is running.
18. Exit X
19. stop inetd
20. stop rpcbind
21. make sure no rpc.cmsd or rpc.ttdbserver processes are running.
22. start rpcbind
23. start inetd
startx /usr/dt/bin/Xsession
Must work at this point :)
