Openvpn makes suddenly certificate 0 bytes

tomislav91 · 06-27-2017, 12:08 PM

Hi, I am running a openvpn server where create certs and put on pcs. I noticed that after unplug and plug network cable to server that now 0 bytes certificate is creating. In keys folder i notice that allways with sertificate generating a .pem file. Now there is no .pem file, only 4 files .ovpn, .key and so on. Where can be mistake? I try on virtual machine with my /var/www and with my /etc/openvpn folders and its working, but on live machine dont, I tried to remove index.txt file in keys folder but not working. I restarter openvpn and apache service and same error.

Thanks in advance!

What's log output after link down and up?

A certificate can become zero bytes if there's already an entry for it in its database file (conf/index).

You will get an "Error 3" (or somesuch) message instead of "Data Base Updated."

I put any name and got 0 bytes. I cant figure why this error shows up. Do you maybe have some advice what to try or something to do?

If certificate is 0 byte, it means that an error come out during link down and up. The certificate generation stop. The log might tell you something.

can you tell me where to find that log?

1)If you are using the network manager plugin (network-manager-openvpn), look into /var/log/syslog
This should give you the last logs of openvpn:

$ grep VPN /var/log/syslog

Connection details are to be found in /etc/openvpn/

2)You can configure where log is saved.
However, your config files can set the logfile location explicitly, e.g.:

log-append /var/log/openvpn.log

3)The --verb option can be used to set the log file verbosity from 0 (no output except for fatal errors) to 11 (for maximum debugging information).

i found log in /etc/openvpn openvpn.log and try to create CERT. i see that file last modifed is time and date now, which i try to make it, but in log file there is no errors, just some connection goes through these days. Nothing about now. In last line just stay todays date.

Code:

Sun Aug 20

. I found some error like TLS handshake failed and thats all. i find some error PHP Notice: Undefined offset 1 in error_log in /var/log/httpd.
this line is:

Code:

list($u1, $u2) = split(",", $line); $u1 = ltrim(rtrim($u1)); $u2 = ltrim(rtrim($u2));

I cant figure out where is problem. No one change anything of code inside php. Maybe to restart php service? I tried with openvpn and apache2.
