Thanks for the quick response. The journalctl tool is certainly powerful and useful. I'll have to spend some time learning its tricks. Here is the output:
I can see it is timing out but can't see why this is happening all of a sudden.
Hi All:
I need a script that can be timed to run every half hour to an hour to run a traceroute through a VPN to test that a connection is still up from a Win XP system. Which would be the best, C++ or Perl and what are some good resources to look at.
(If anyone has a script to do this... (1 Reply)

Any ideas what can cause this to happen? Is there someway that UDP traffic could... (0 Replies)

Hi everyone,
I am hoping anyone of you could help me in this weird problem we have in 1 of our Solaris 10 servers. Lately, we have been having some ftp problems in this server. Though it can ping any server within the network, it seems that it can only ftp to a select few. For most servers, the... (4 Replies)
I would like to know if anyone has a way to PRINT TO a printer attached to a Windows 7 PC, from SCO, while logged in via a VPN connection.

tincd
TINCD(8) BSD System Manager's Manual TINCD(8)NAME
tincd -- tinc VPN daemon
SYNOPSIS
tincd [-cdDkKnoLRU] [--config=DIR] [--no-detach] [--debug[=LEVEL]] [--kill[=SIGNAL]] [--net=NETNAME] [--generate-keys[=BITS]]
[--option=[HOST.]KEY=VALUE] [--mlock] [--logfile[=FILE]] [--pidfile=FILE] [--bypass-security] [--chroot] [--user=USER] [--help]
[--version]
DESCRIPTION
This is the daemon of tinc, a secure virtual private network (VPN) project. When started, tincd will read it's configuration file to deter-
mine what virtual subnets it has to serve and to what other tinc daemons it should connect. It will connect to the ethertap or tun/tap
device and set up a socket for incoming connections. Optionally a script will be executed to further configure the virtual device. If that
succeeds, it will detach from the controlling terminal and continue in the background, accepting and setting up connections to other tinc
daemons that are part of the virtual private network. Under Windows (not Cygwin) tinc will install itself as a service, which will be
restarted automatically after reboots.
OPTIONS -c, --config=DIR
Read configuration files from DIR instead of /etc/tinc/.
-D, --no-detach
Don't fork and detach. This will also disable the automatic restart mechanism for fatal errors. If not mentioned otherwise, this
will show log messages on the standard error output.
-d, --debug[=LEVEL]
Increase debug level or set it to LEVEL (see below).
-k, --kill[=SIGNAL]
Attempt to kill a running tincd (optionally with the specified SIGNAL instead of SIGTERM) and exit. Under Windows (not Cygwin) the
optional argument is ignored, the service will always be stopped and removed.
-n, --net=NETNAME
Connect to net NETNAME. This will let tinc read all configuration files from /etc/tinc/ NETNAME. Specifying . for NETNAME is the
same as not specifying any NETNAME.
-K, --generate-keys[=BITS]
Generate public/private RSA keypair and exit. If BITS is omitted, the default length will be 2048 bits. When saving keys to exist-
ing files, tinc will not delete the old keys, you have to remove them manually.
-o, --option=[HOST.]KEY=VALUE
Without specifying a HOST, this will set server configuration variable KEY to VALUE. If specified as HOST.KEY=VALUE, this will set
the host configuration variable KEY of the host named HOST to VALUE. This option can be used more than once to specify multiple con-
figuration variables.
-L, --mlock
Lock tinc into main memory. This will prevent sensitive data like shared private keys to be written to the system swap files/parti-
tions.
--logfile[=FILE]
Write log entries to a file instead of to the system logging facility. If FILE is omitted, the default is /var/log/tinc.NETNAME.log.
--pidfile=FILE
Write PID to FILE instead of /var/run/tinc.NETNAME.pid. Under Windows this option will be ignored.
--bypass-security
Disables encryption and authentication of the meta protocol. Only useful for debugging.
-R, --chroot
With this option tinc chroots into the directory where network config is located (/etc/tinc/NETNAME if -n option is used, or to the
directory specified with -c option) after initialization.
-U, --user=USER
setuid to the specified USER after initialization.
--help Display short list of options.
--version
Output version information and exit.
SIGNALS
ALRM Forces tincd to try to connect to all uplinks immediately. Usually tincd attempts to do this itself, but increases the time it waits
between the attempts each time it failed, and if tincd didn't succeed to connect to an uplink the first time after it started, it
defaults to the maximum time of 15 minutes.
HUP Partially rereads configuration files. Connections to hosts whose host config file are removed are closed. New outgoing connections
specified in tinc.conf will be made. If the --logfile option is used, this will also close and reopen the log file, useful when log
rotation is used.
INT Temporarily increases debug level to 5. Send this signal again to revert to the original level.
USR1 Dumps the connection list to syslog.
USR2 Dumps virtual network device statistics, all known nodes, edges and subnets to syslog.
WINCH Purges all information remembered about unreachable nodes.
DEBUG LEVELS
The tinc daemon can send a lot of messages to the syslog. The higher the debug level, the more messages it will log. Each level inherits
all messages of the previous level:
0 This will log a message indicating tincd has started along with a version number. It will also log any serious error.
1 This will log all connections that are made with other tinc daemons.
2 This will log status and error messages from scripts and other tinc daemons.
3 This will log all requests that are exchanged with other tinc daemons. These include authentication, key exchange and connection list
updates.
4 This will log a copy of everything received on the meta socket.
5 This will log all network traffic over the virtual private network.
FILES
/etc/tinc/
Directory containing the configuration files tinc uses. For more information, see tinc.conf(5).
/var/run/tinc.NETNAME.pid
The PID of the currently running tincd is stored in this file.
BUGS
The BindToInterface option may not work correctly.
The cryptography in tinc is not well tested yet. Use it at your own risk!
If you find any bugs, report them to tinc@tinc-vpn.org.
TODO
A lot, especially security auditing.
