I have OpenSuSE 11.4 and Slackware 13.37. On both machines there is vpnc client. If I start vpnc connection is successfull, I can start work. After period of time (if there is no activity this period is around 10 minutes and if there is activity period is different every time) connection is "lost". I have no ping t0 the vpn network but 'ifconfig' show me the interface:
tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:192.168.255.78 P-t-P:192.168.255.78 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1412 Metric:1 RX packets:766 errors:0 dropped:0 overruns:0 frame:0 TX packets:1205 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:126464 (123.5 KiB) TX bytes:111763 (109.1 KiB)
If I run 'show crypto session' on cisco router I receive that my connection is active:
Interface: Virtual-Access16 Username: XXXXX Profile: XXXXXXX Group: XXXXXX Assigned address: 192.168.255.78 Session status: UP-ACTIVE Peer: xx.xx.xx.xx port 24228 IKE SA: local 192.168.1.2/4500 remote xx.xx.xx.xx/24228 Active IPSEC FLOW: permit ip 0.0.0.0/0.0.0.0 host 192.168.255.78 Active SAs: 4, origin: crypto map
If I try to reconnect without manually issue disconnect I receive:
root@darkstar:~# vpnc server vpnc: Error binding to source port. Try '--local-port 0' Failed to bind to 0.0.0.0:4500: Address already in use root@darkstar:~#
so my connection must be active but it is not :(.
If I issue
vpnc-disconnect and then
vpnc server I am connected with new IP address and the problem continue to appear.
