Hi, I installed openVPN on centos 6 64bit based on several tutorials i found on the internet. Somehow, i am seeing the error message ""TCP/UDP: Socket bind failed on local address :1194" whenever i stop and start the openvpn service. Is there anything that i missed out? Please help. Thanks.

hi there, [quote]TCP/UDP: Socket bind failed on local address :1194[/quote] means that something already uses 1194 port... if you issue ps ax | grep openvpn BEFORE you start openvpn does it reports anything back? also post the output of sestatus regards, Michael.

Hi, ps and sestatus gave me the result as below: [root@comp1 ~]# ps ax | grep openvpn 1780 ? S 0:00 openvpn /etc/openvpn/config-default.conf 3065 ? S 0:00 openvpn /etc/openvpn/config-default.conf 7318 pts/1 S+ 0:00 grep openvpn [root@box1 ~]# sestatus SELinux status: disabled [root@comp1 ~]#

openvpn is already running..? please remove any unused config and restart service Michael.

[root@comp1 ~]# ps ax | grep openvpn 7356 pts/1 S 0:00 /usr/sbin/openvpn --daemon --writepid /var/run/openvpn/config-default.pid --config config-default.conf --cd /etc/openvpn --script-security 2 7364 ?

after stopping openvpn try to start it using: openvpn --config /etc/openvpn/configfile.conf and see if it comes up... Michael.

Hi, seems like i don't have this config file..i'm using the default [root@comp1 openvpn]# openvpn --config /etc/openvpn/configfile.conf Options error: In [CMD-LINE]:1: Error opening configuration file: /etc/openvpn/configfile.conf Use --help for more information. [root@comp1 openvpn]# pwd /etc/openvpn [root@comp1 openvpn]# ls 1194.log config-default.conf easy-rsa [root@comp1 openvpn]#

"config-default.conf" is the file that i'm using in my configuration where i updated for my server IP add and stuff.

simply substitute the "configfile.conf" with your config filename... is it starting ok? Michael.

i rename my config file to configfile.conf. then i started openvpn with the command 'openvpn --config configfile.conf" i am getting below: [root@comp1 openvpn]# openvpn --config configfile.conf Wed Feb 13 09:35:13 2013 OpenVPN 2.2.2 x86_64-unknown-linux-gnu [SSL] [LZO2] [EPOLL] [PKCS11] [eurephia] built on Apr 5 2012 Wed Feb 13 09:35:13 2013 NOTE: OpenVPN 2.1 requires '--script-security 2' or higher to call user-defined scripts or executables Wed Feb 13 09:35:13 2013 PLUGIN_INIT: POST /usr/share/openvpn/plugin/lib/openvpn-auth-pam.so '[/usr/share/openvpn/plugin/lib/openvpn-auth-pam.so] [/etc/pam.d/login]' intercepted=PLUGIN_AUTH_USER_PASS_VERIFY Wed Feb 13 09:35:13 2013 Diffie-Hellman initialized with 1024 bit key Wed Feb 13 09:35:13 2013 WARNING: POTENTIALLY DANGEROUS OPTION --client-cert-not-required may accept clients which do not present a certificate Wed Feb 13 09:35:13 2013 TLS-Auth MTU parms [ L:1574 D:138 EF:38 EB:0 ET:0 EL:0 ] Wed Feb 13 09:35:13 2013 Socket Buffers: R=[229376->131072] S=[229376->131072] Wed Feb 13 09:35:13 2013 ROUTE default_gateway= Wed Feb 13 09:35:13 2013 TUN/TAP device tun0 opened Wed Feb 13 09:35:13 2013 TUN/TAP TX queue length set to 100 Wed Feb 13 09:35:13 2013 /sbin/ip link set dev tun0 up mtu 1500 Wed Feb 13 09:35:13 2013 /sbin/ip addr add dev tun0 local 1.2.3.1 peer 1.2.3.2 Wed Feb 13 09:35:13 2013 /sbin/ip route add 1.2.3.0/24 via 1.2.3.2 Wed Feb 13 09:35:13 2013 Data Channel MTU parms [ L:1574 D:1450 EF:42 EB:135 ET:32 EL:0 AF:3/1 ] Wed Feb 13 09:35:13 2013 UDPv4 link local (bound): :1194 Wed Feb 13 09:35:13 2013 UDPv4 link remote: [undef] Wed Feb 13 09:35:13 2013 MULTI: multi_init called, r=256 v=256 Wed Feb 13 09:35:13 2013 IFCONFIG POOL: base=1.2.3.4 size=62 Wed Feb 13 09:35:13 2013 Initialization Sequence Completed when i check the openvpn process, i was getting 2 llines: [root@comp1 ~]# ps ax | grep openvpn 9874 pts/0 S+ 0:00 openvpn --config configfile.conf 9875 pts/0 S+ 0:00 openvpn --config configfile.conf 9885 pts/1 S+ 0:00 grep openvpn [root@comp1 ~]# i killed all openvpn process before i started though, but once i started, there seems to be 2 processes.

Any advice?

thanks.

maikcat

is the openvpn service & interface comes up or not?

Michael.
