Re: [Radiusplugin-users] Possible bug / weird occurence

[Dequan]

Following on from this, a 'find in files' for the word 'replace' only
returns 1 entry -- radiusplugin.cpp line 1100:

        string getTime()
        {
                time_t rawtime;
                struct tm * timeinfo;
                time ( &rawtime );
                timeinfo = localtime ( &rawtime );
                string t(ctime(&rawtime));
                t.replace(t.find("\n"),1," ");
                return t;
        }

Is it possible this is causing the error:

        std::out_of_range
        what():  basic_string::replace

or, am I trying to find bugs where there are none?!

Hi Ralf,

I have 4 OpenVPN instances running on my server (2 TCP / 2 UDP) all
running radiusplugin with 4 separate radiusplugin configs.

Normally everything runs fine, but say.. once every day (there is no real
frequency or reliability in replicating this), one of the OpenVPN
instances would crash with the following error in the OpenVPN log --
leading me to assume it's either an OpenVPN or radiusplugin issue:

        Thu Aug 25 20:09:41 2011 219.147.190.77:3475 Data Channel Encrypt:
Cipher 'AES-256-CBC' initialized with 256 bit key
        Thu Aug 25 20:09:41 2011 219.147.190.77:3475 Datstd::out_of_range'
        Thu Aug 25 20:09:41 2011 219.147.190.77:3475 Data Channel Decrypt:
Cipher 'AES-256-CBC' initialized with 256 bit key
        what():  basic_string::replaceT
        Thu Aug 25 20:09:41 2011 219.147.190.77:3475 Data Channel Decrypt:
Using 160 bit message hash 'SHA1' for HMAC authentication

This is the only thing I can find that is causing the issue which forces
me to restart all instances and resetting everyone's connection. Sorry to
presume, but I am guessing that something 'weird' is happening in the
radiusplugin and giving the errors:

        std::out_of_range
        what():  basic_string::replace

I can find nothing else except the above in the logs (corresponding to
around the same timeframe) that would cause one of the OpenVPN instances
to crash -- and assume it is a weird error arising for the radiusplugin.

I'm sorry I have nothing more to go on, but do you have any idea if this
is actually caused by the radiusplugin? It's a bit of a leap, but is it
possible that there is the ability to input something 'weird' into the
radiusplugin -- somewhere -- that would result in this error? I am
assuming I do not need a radiusplugin.so for every OpenVPN instance, and
that a separate radiusplugin config file for each instance is the correct
method?

Dequan.
