Hello,

I would like to find out if I can use STunnel as follows:

I have a stand alone C# executable program that uses a third party SDK that implements SMPP protocol and sends SMS text messages with wireless carriers. Recently, one of the wireless carriers wants us to implement SSL Client Authentication and wants SMPP messages that are exchanged with them to be encrypted after the client authentication is done.

I want to find out if I can use STunnel running so that STunnel can encrypt and decrypt the messages exchanged between my program and the carrier's SMS server.

(1) Is this possible with STunnel? (2) What are the steps involved?

I am on the Windows Server 2003 platform.

I would really appreciate a reply.

Thanks, Apu

Hello, Provided that you are using SMPP over TCP/IP (not over X25), yes you could use stunnel. Next you have to know what port(s) are involved at the server side (ie the "listening" socket(s)): apparently there are two flavors of smpp over tcp: one using two network connections, the other using only one ("tranceiver session").

Things will be more simple if you are using only one connection. If you are using two connections, and provided that ssl is required on both, just duplicate [smpp] section below as [smpp1] and [smpp2], of course changing the "accept" and "connect" ports.

Then you have to get a valid CLIENT certificate (crt file) and key file.

Stunnel.conf can then look like this : ;------ ; stunnel CLIENT conf

[smpps] client = yes

accept=127.0.0.1:CHOOSE A LOCAL LISTENING PORT ON THE CLIENT connect=SERVER_IP_ADDR:SERVER_LISTENING_PORT

cert=\localLocation\userXXXcert.crt key =\localLocation\userXXXcert.key

;often useful : sslVersion=all ;-----------

And of course you have to redirect your smpp client software to the "pseudo smpp over ssl" local server(s) on localhost, (cf "local listening port" above).

Hope this may help, Pierre Delaage

New subject: Error Running STunnel in Windows Service Mode

Hi All,

I am having some issues running STunnel in Windows Service Mode.

I am running on Windows Server 2003, Service Pack 1.

stunnel 4.33

1. I was able to successfully install it as a service, as follows: Start > Programs > stunnel > Service Install 2. Stunnel Shows up as a Service in Windows Service 3. But when I try to start it either from the Windows Service area or the: Start > Programs > stunnel > Service start I get the following error, in a dialog box with an OK button:

stunnel 4.33 on win32 (stunnel)

StartService: error 1053: The service did not respond to the start or control request in a timely fashion.

1. I am able to actually Run stunnel, as: Start > Programs > stunnel > Run stunnel and do my SMPP work successfully! But of course, as soon as I log off the server, stunnel stops and my SMPP session is not encrypted and my Bind ends. So I really need the Windows Service mode to run urgently. I would really appreciate some help on what is going wrong, so that I can get run Stunnel in the Service mode

The stunnel.conf file is as follows: =================== cert = carrier.cer key = carrier.key

; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1

; Some debugging stuff useful for troubleshooting debug = 7 output = stunnel.log

; Service-level configuration

; IS ADDING SMPP AS SIMPLE AS ADDING IT HERE??? [ssmpp]

accept = 127.0.0.1:3005 connect = REMOTE_IP:9000

; Use it for client mode client = yes options = all

;often useful : sslVersion=all ;-----------

New subject: Error Running STunnel in Windows Service Mode

I forgot to mention one thing:

The private key, in the config file "carrier.key" needs a Pass phrase that I need to enter manually when I do "Run stunnel" which does not pop up when I try to run STunnnel in Windows Service mode. May be that is the problems - it's looking for the pass phrase and not able to start? Can I specify the passphrase some where in the config file?

Help would be appreciated.

New subject: Error Running STunnel in Windows Service Mode

Hi, In service mode, one has to remove the password protection from cert file. It is typical when ones want to automate ssl sessions. I think it is pointed out in some docs, but I do not remember where...

Here is slightly modified information:

When I do the following:

1. When I try to start Stunnel from: Start > Programs > stunnel > Service start I get the following error, in a dialog box with an OK button:

I do get the pop up to enter the pass-phrase for "carrier.key" (the stunnel.conf is below) - but I still get the following error:

stunnel 4.33 on win32 (stunnel)

StartService: error 1053: The service did not respond to the start or control request in a timely fashion.

And when I try to start the stunnel service directly from the Windows Service area, I do not get the pop-up to enter the pass-phrase for "carrier.key" (the stunnel.conf is below), but I do get the above error.

I would appreciate your help.

New subject: Error: faulting application stunnel.exe, version 0.0.0.0, faulting module libeay32.dll, version 1.0.0.1, fault address 0x0007331e.

Hello,

I am getting an error with using stunnel 4.34. I am running on Windows Server 2003. Unfortunately, this has cropped up only after we went to production, so there is no turning back now. Urgent help is needed.

Reporting queued error: faulting application stunnel.exe, version 0.0.0.0, faulting module libeay32.dll, version 1.0.0.1, fault address 0x0007331e.

I am using stunnel to encrypt SMPP (or SMS text messages).

The above error is occurring very frequently when I run stunnel in Windows Service mode. Once this happens and I go through the same two steps to re-establish binds with my wireless carrier (1) restart stunnel (2) restart my SMPP service. The following happens (1) Stunnel starts with: Option SO_REUSEADDR set on accept socket (2) I am not able to establish binds error in stunnel.log: SSL_accept: 140760FC: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol

When the above error is happening, the way to get things to work is to go: Start > Programs > stunnel > Start Service and things still work (Stunnel runs as me in user mode and not as "SYSTEM", stunnel does still start with Option SO_REUSEADDR set on accept socket but binds starts OK). Of course, as soon as I log off the server, everything stops so this of not much use, but this is working for some reason.

Hi Apurva, For us to help, we need your stunnel.conf. Is this bug NEW ? was there a recent change either on client-side or server-side ?

Can you try with LAST (recent versions) of openssl (there are TWO ! 100b and 098p) ? ...

Hello,

*I am getting an error with using stunnel 4.34*. *I am running on Windows Server 2003. *Unfortunately, this has cropped up only after we went to production, so there is no turning back now. Urgent help is needed.

*Reporting queued error: faulting application stunnel.exe, version 0.0.0.0, faulting module libeay32.dll, version 1.0.0.1, fault address 0x0007331e.*

I am using stunnel to encrypt SMPP (or SMS text messages).

The above error is occurring very frequently when I run stunnel in Windows Service mode. *Once this happens* and I go through the same two steps to re-establish binds with my wireless carrier (1) restart stunnel (2) restart my SMPP service. The following happens (1) *Stunnel starts with: **Option SO_REUSEADDR set on accept socket* (2) I am not able to establish binds error in *stunnel.log*: *SSL_accept: 140760FC: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol*

When the above error is happening, the way to get things to work is to go: *Start > Programs > stunnel >* *Start Service *and things still work (Stunnel runs as me in user mode and not as "SYSTEM", stunnel does still start with *Option SO_REUSEADDR set on accept socket but binds starts OK*). Of course, as soon as I log off the server, everything stops so this of not much use, but this is working for some reason.

New subject: Error: faulting application stunnel.exe, version 0.0.0.0, faulting module libeay32.dll, version 1.0.0.1, fault address 0x0007331e.

Hi Pierre,

You are right, I had the same ACCEPT port mentioned three times - something that worked for several hours and then caused problems - I guess the symptom was the error with libeay32.dll (I am hoping it was that and nothing else). Actually I needed it only once and then my ESME application could establish many connections to it.

Also, I disabled:

TCP_NODELAY options in my stunnel.conf as you suggested and also disabled sslVersion=all as suggested by the carrier.

Since making these changes, things have been stable so I am not getting a different version of the libeay32.dll 1.0.0.1 at this time.

;often useful : ;sslVersion=all ;-----------

Here is my example stunne.conf ; Sample stunnel configuration file by Michal Trojnara 2002-2006 ; Some options used here may not be adequate for your particular configuration

; Certificate/key is needed in server mode and optional in client mode ; The default certificate is provided only for testing and should not ; be used in a production environment

cert = carrier.cer key = carrier.key

; Some performance tunings ;socket = l:TCP_NODELAY=1 ;socket = r:TCP_NODELAY=1

; TURN THIS ON TO MAX ; Some debugging stuff useful for troubleshooting debug = 7 output = stunnel.log

; Service-level configuration

; Have this only once and ESME application can establish several connections (as many as allowed by the ; carrier SMSC, that is) [ssmpp1] accept = 127.0.0.1:3003 connect = <DESTINATION_IP_REMOTE>:<DESTIONATION_PORT_REMOTE>

; Use it for client mode client = yes ; Suggested by client options = all

;Suggested by client to disable this ;often useful : ;sslVersion=all ;-----------

Thanks a lot for your help! Apurva

Unfortunately, this has cropped up only after we went to production, so there is no turning back now. Urgent help is needed. Reporting queued error: faulting application stunnel.exe, version 0.0.0.0, faulting module libeay32.dll, version 1.0.0.1, fault address 0x0007331e.

Once this happens and I go through the same two steps to re-establish binds with my wireless carrier (1) restart stunnel (2) restart my SMPP service.

Hi Apurva, Good news. Just to mention: SslVersion=all OFTEN SOLVES MANY PROBLEMS in various circumstances. So I would keep it... Just search for it in the mailing list and you will see...

This is just an advice...

Hello,

*I am getting an error with using stunnel 4.34*. *I am running on Windows Server 2003. *Unfortunately, this has cropped up only after we went to production, so there is no turning back now. Urgent help is needed.

*Reporting queued error: faulting application stunnel.exe, version 0.0.0.0, faulting module libeay32.dll, version 1.0.0.1, fault address 0x0007331e.*

I am using stunnel to encrypt SMPP (or SMS text messages).

The above error is occurring very frequently when I run stunnel in Windows Service mode. *Once this happens* and I go through the same two steps to re-establish binds with my wireless carrier (1) restart stunnel (2) restart my SMPP service. The following happens (1) *Stunnel starts with: **Option SO_REUSEADDR set on accept socket* (2) I am not able to establish binds error in *stunnel.log*: *SSL_accept: 140760FC: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol*

When the above error is happening, the way to get things to work is to go: *Start > Programs > stunnel >* *Start Service *and things still work (Stunnel runs as me in user mode and not as "SYSTEM", stunnel does still start with *Option SO_REUSEADDR set on accept socket but binds starts OK*). Of course, as soon as I log off the server, everything stops so this of not much use, but this is working for some reason.

Complete stunnel.log:

I also meant solving interoperability problems. Interoperability with my MITM exploits to be more precise. Security is just the usual price to be paid for maxing out the interoperability.
