pingpong1109 Posted July 19, 2016 Share Posted July 19, 2016 I know the title doesn't describe the problem but it is more complicated than a title... I was following the OpenVPN tutorial from Hak5 that was posted recently. I followed it VERY closely besides naming my server and client differently. I know my way around Linux though not a pro but here is what I have tried (I tried these all under root just in case). # ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether fa:16:3e:95:61:ab brd ff:ff:ff:ff:ff:ff inet SERVERIP/32 brd SERVERIP scope global eth0 valid_lft forever preferred_lft forever inet6 fe80::f816:3eff:fe95:61ab/64 scope link valid_lft forever preferred_lft forever # ifconfig eth0 Link encap:Ethernet HWaddr fa:16:3e:95:61:ab inet addr:SERVERIP Bcast:SERVERIP Mask:255.255.255.255 inet6 addr: fe80::f816:3eff:fe95:61ab/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:109196 errors:0 dropped:0 overruns:0 frame:0 TX packets:90345 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:11802396 (11.2 MiB) TX bytes:13847838 (13.2 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:2 errors:0 dropped:0 overruns:0 frame:0 TX packets:2 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:88 (88.0 B) TX bytes:88 (88.0 B) # ufw status Status: active To Action From -- ------ ---- 22 ALLOW Anywhere 1194/udp ALLOW Anywhere # ps aux | grep openvpn root 7356 0.0 0.0 12664 1544 pts/0 S+ 18:46 0:00 grep openvpn # nmap -sU 127.0.0.1 Starting Nmap 6.47 ( http://nmap.org ) at 2016-07-19 18:47 EDT Nmap scan report for localhost (127.0.0.1) Host is up (0.000012s latency).

What I think is wrong is that there is no tun interface. Quote Link to comment Share on other sites More sharing options...
