problem with --auth-user-pass-verify

Post by noobzilla89 » Sat Aug 01, 2015 10:59 pm

hey guys,
i have a problem with my openvpn config. i wrote an sh-script for user-pass-verify which works stand-alone. but im always getting the error "WARNING: Failed running command (--auth-user-pass-verify): could not execute external program" in the log.
I googled a lot but have still no solution for it.

Here is my server.conf:
port 11950
proto udp
dev tap0
ca ca-homeserver.crt
cert homeserver.crt
key homeserver.key
dh dh4096.pem
server-bridge 10.5.9.1 255.255.255.0 10.5.9.201 10.5.9.250
push "route 10.5.9.0 255.255.255.0"
user root
reneg-sec 68400
tls-auth ta.key
username-as-common-name
auth-user-pass-verify /etc/openvpn/script/login.sh via-env
client-to-client
keepalive 10 120
comp-lzo
max-clients 50
persist-key
persist-tun
script-security 3 system
status homeserver.log
log-append openvpn.log
verb 3
And the login.sh-script:
username=$1
password=$2

passwordhash=$(mysql -h'localhost' -P'3306' -u'dbuser' -p'dbpass' dbname -sN -e "select right((select password from table where uid = '$username'), 60)")

returnval=$(php /etc/openvpn/script/newhashtest.php "$password" "$passwordhash")

[ $returnval ] && echo "auth for user '$username' ok" && exit 0 || echo "auth failed"; exit 1
i think there are some problems with file permissions, but i tested "chmod 777 login.sh" and it had no effect. always getting the could-not-execute error...
i had the same server.conf running on my server before i formatted it with debian 8 jessie last week to give everything a new start.

i hope someone can help me fixing this problem. thanks a lot!

i found the line " PID_ERR replay-window backtrack occurred" for the first time now and tried to set the protocol to tcp. the log shows the same "Failed running command (--auth-user-pass-verify)" as before, only the line "PID_ERR..." is missing with TCP instead of UDP so i changed server.conf (and client of course) back to UDP protocol.
Any other suggestions?

This could be due to OpenVPN requiring /full/path/to/.. mysql & php ... :geek:

( also --verb 5 long lines yuk ... :roll: )

openvpn complains that
Failed running command (--auth-user-pass-verify): could not execute external program
could not execute script at all , not someting like "i executed it but i deny access..."

just my 2 cents though...

please post the output i requested...

Further testing reveals:
noobzilla89 wrote:WARNING: Failed running command (--auth-user-pass-verify): could not execute external program
"external program" indicates that the script has failed to execute the external program ..

My log:

My config (Default server config plus this):

It is worth pointing out this is wrong:

$1 and $2 do not contain the username and password .. they are passed via environment variables ...

traffic is right....
If method is set to "via-env", OpenVPN will call script with the environmental variables username and password set to the username/password strings provided by the client. Be aware that this method is insecure on some platforms which make the environment of a process publicly visible to other unprivileged processes.

Re: problem with --auth-user-pass-verify

Post by noobzilla89 » Thu Aug 27, 2015 9:26 am

output of ls is:

Code: Select all

-rwsrwsrwt 1 root root 365 Aug  2 07:49 /etc/openvpn/script/login.sh
(i did a chmod 777 to avoid permission errors)
ohh, what a big mistake with the variables... but even if i dont set the variables (commented the two lines out) but only use them given from openvpn process, the error is still alive. i also changed the mysql and php command to /bin/usr/..., but that didnt have any effect.
maybe the error is that the database password has a " inside? i escaped it and if i call the script from bash it works correctly, so i think there shouldnt be an error...
But i dont think that openvpn will tell me, if a command inside my script fails. it will only give me an "auth ok" or "auth failed". so the main thing is still the permission to execute the script.
any other ideas?

2 things,

you issued an chmod 7777 not an chmod 777...
use chmod 0777 on login.sh please.
OpenVPN will call script with the environmental variables username and password set to the username/password strings provided by the client
what traffic and i posted earlier is that instead of $1 and $2 you should use $username & $password variables which openvpn uses for the credentials...

i used chmod 0777 now, but still the same error.

the variables i tried to fill with $1 and $2 were called username and password so there is no need to apply any other changes in the script. script looks now like:
passwordhash=$(/usr/bin/mysql -h'localhost' -P'3306' -u'owncloud' -p"Oc\"0!5" owncloud -sN -e "select right((select password from oc_users where uid = '$username'), 60)")

returnval=$(/usr/bin/php /etc/openvpn/script/newhashtest.php "$password" "$passwordhash")

[ $returnval ] && echo "auth for user '$username' ok" && exit 0 || echo "auth failed"; exit 1

i also tried to make a new script login2.sh which i used to "confirm" login. this consists only of the line "exit 0", which confirms authorization. i of course did chmod +x, but still the same error. the openvpn process is running as root properly.
any other suggestions?

Did you change your server config to match:

and restart the server ?

Try this:

Code: Select all

#!/bin/bash

exit 0
