DESCRIPTION

16       VTun provides the method for creating Virtual Tunnels over TCP/IP  net‐
17       works and allows to shape, compress, encrypt traffic in that tunnels.
18
19       Supported  type  of  tunnels  are:  PPP, IP, Ethernet and most of other
20       serial protocols and programs.
21
22       VTun is easily and highly configurable, it can be used for various net‐
23       work  task like VPN, Mobile IP, Shaped Internet access, IP address sav‐
24       ing, etc.
25
26       It is completely user space implementation and does not require modifi‐
27       cation to any kernel parts.

OPTIONS

31       -f file
32              Read  config  information from the file (full path required). By
33              default vtund uses /etc/vtund.conf
34
35       -n     Do not become daemon (required on no-MMU systems).
36
37   Server mode:
38       -s     Run as the server (not available on no-MMU systems).
39
40       -i     Run as the inetd server.
41
42       -P port
43              Listen for connection on the specified  port  By  default  vtund
44              listens  on  TCP  port  5000.  This options is equivalent to the
45              'port' option of config file.
46
47   Client mode:
48       -P port
49              Connect to the server on the specified  port  By  default  vtund
50              connects  to  TCP  port  5000. This options is equivalent to the
51              'port' option of config file.
52
53       -p     Reconnect to the server after connection termination. By default
54              vtund  will exit if connection has been terminated. This options
55              is equivalent to the 'persist' option of config file.
56
57       -q     Inhibit the printing of connection messages.
58
59       -m     Force memory pages  to  be  locked  memory-resident  to  prevent
60              potential  VM  deadlock.   Useful with NFS traffic.  This option
61              has no config file equivalent.
62
63       -t timeout
64              Connect timeout Default is 30 seconds. This options  is  equiva‐
65              lent to the 'timeout' option of config file.
66
67       session
68              Session name from the config file.
69
70       server Address of the server to connect to. Either IP address or domain
71              name can be specified.
72

FILES

74       /etc/vtund.conf
75              Main configuration file with  sessions  and  other  information.
76              See   vtund.conf   example   provided   with   distribution  and
77              vtund.conf(5) for more information.
78
79       /var/lock/vtund/
80              Session lock files.
81
82       /var/log/vtund/
83              Connection statistic log files.
84              Format:
85                 Date Uncomp_In Uncomp_Out Comp_In Comp_Out
86

SIGNALS

88       SIGHUP Server mode: Causes vtund to reread the config file.
89              Client mode: Causes vtund to reestablish the connection.
90
91       SIGUSR1
92              This signal causes vtund to reset statistic counters.
