Hello all,
I`m running the OVPN server on a NAS from Synology with self generated
certificates (XCA).
A few day`s i`m trying to get a tls-verify script running but somehow i cannot
find what is wrong.
The following script, ovpnCNcheck.sh, i found on the net:
(removed comments)
************************
#!/bin/sh
[ $# -eq 3 ] || { echo usage: ovpnCNcheck.sh userfile certificate_depth
X509_NAME_oneline ; exit 255 ; }
# $2 -> certificate_depth
if [ $2 -eq 0 ] ; then
# $3 -> X509_NAME_oneline
# $1 -> cn we are looking for
grep -q "^`expr match "$3" ".*/CN=\([^/][^/]*\)"`$" "$1" && exit 0
exit 1
fi
exit 0
*********************
I gave the file 0755 and placed a textfile also 0755, containing the commonname
of the client, in the same directory.
In the config from server:
tls-verify "/volume1/@appstore/VPNCenter/scripts/ovpnCNcheck.sh
/volume1/@appstore/VPNCenter/scripts/userlist.txt"
When the client connects, username/password and then stalls, the server log
gives:
*************************

***************************
As i have no understanding from the script, i still would appriciate if someone
can take a look at this.
Thanks in advance,
André
