I have a centos 6 server 64bit running openvpn-2.3.2-2.el6.x86_64.
I'm running openvpn as a client connecting to an internet based vpn service and sometimes when I try to connect I get:
WARNING: No server certificate verification method has been enabled.
this happens for no seeable reason and once this failure happens
nothing will resolve it except a reboot of the machine, and after a reboot it connects perfectly first time. The log says:
OpenVPN 2.3.2 x86_64-redhat-linux-gnu [SSL (OpenSSL)] [LZO] [EPOLL] [PKCS11] [eurephia] [MH] [IPv6] built on Sep 12 2013
WARNING: No server certificate verification method has been enabled. See
http://openvpn.net/howto.html#mitm for more info.
Socket bind failed on local address [undef]: Address already in use
Exiting due to fatal error
I don't understand the bit in the log about ' Address already in use'. what address would that be? and how could I get past this problem without rebooting the machine?
