 Subject:  OpenVPN - ifconfig: interface tap0 does not exist
 Date:  Mon, 25 Oct 2004 11:21:59 +0200
Hi again!

My next OpenVPN problem :)
After I switched to TUN device and back to TAP my m0n0wall neither
wants to create a tap nor a tun interface.

Interface status screen tells me "ifconfig: interface tap0 does not exist"
Yesterday it worked perfectly now it doesn't anymore without any special 
reason :(

--- 10 minutes later ---

I just tried to restart OpenVPN and now I'm able to see a syslog 
message, which tells me:

openvpn[448]: Cannot load certificate file /var/db/ovpn_srv_cert.pem: 
error:0906D066:PEM routines:PEM_read_bio:bad end line: 
error:140AD009:SSL routines:SSL_CTX_use_certificate_file:PEM lib

A cat on /var/db/ovpn_srv_cert.pem tells me that there are 3 empty line 
in the middle of
my certificate:

I definitely did not copy-pasted those 3 lines inside the config 
textfield, so is it possible
that there is a xml-php parsing error?

Ok, no answer needed anymore for my starting question ;) Now it works again
after removing the lines.

Thanks anyway for reading :)

Greetings,
Andre
