IE tries to verify client certificate?
by Don Werve 15 Mar '06

15 Mar '06

I've got stunnel providing SSL wrapper services for an otherwise SSL-stupid vendor-webserver-thingy that listens on port 80. I'm using a wildcard certificate purchased from $VENDOR, and it seems to work fine in Safari, Firefox, w3m, and basically everything SSL aware known to Man. Except, that is, Internet Explorer, where the user gets a popup window asking them to choose a certificate to verify their connection. This is really throwing me for a loop; I've tried setting 'verify = 0' and 'options = ALL' in the service definition under stunnel, no dice. Any ideas why IE thinks it needs to verify, but nothing else does? -- Don Werve <donw(a)iradeon.net> Chief Systems Administrator / Systems Architect

GeoTrust QuickSSL cert and stunnel
by Steve Shepherd 15 Mar '06

15 Mar '06

I've got a client that has a GeoTrust "QuickSSL" certificate (we normally deal with Thawte). I installed the cert/key, but it is not functioning (pulling up default certificate), so I figured I would need the CA. I gathered the CA, so in the file I have: Certificate Private Key Certificate GeoTrust CA Where is the default location to install other CA's and/or chained certs? Thanks!

That would be my guess but the last time I wanted static binaries was Redhat 2.1 on a DEC Alpha-based machine, sorry. -----Original Message----- From: stunnel-users-bounces(a)mirt.net [mailto:stunnel-users-bounces@mirt.net] On Behalf Of Hal Vaughan Sent: Wednesday, March 15, 2006 1:25 PM To: stunnel-users(a)mirt.net Subject: Re: [stunnel-users] Static Version Built?

Do you have static libraries in your SSL lib or just shared libraries? i.e. libssl.a (static) and libssl.so (dynamic) or just one or the other? Have you tested with ldd? For example, on my machine, I get this showing me I'm linking dynamically. ldd /usr/sbin/stunnel libutil.so.1 => /lib/libutil.so.1 (0x40023000) libpthread.so.0 => /lib/i686/libpthread.so.0 (0x40027000) libnsl.so.1 => /lib/libnsl.so.1 (0x4003b000) libdl.so.2 => /lib/libdl.so.2 (0x40050000) libssl.so.2 => /lib/libssl.so.2 (0x40053000) libcrypto.so.2 => /lib/libcrypto.so.2 (0x40080000) libc.so.6 => /lib/i686/libc.so.6 (0x42000000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000) Regards, KAM -----Original Message----- From: Hal Vaughan [mailto:hal@thresholddigital.com] Sent: Wednesday, March 15, 2006 12:55 PM To: Kevin A.

Does it link to those libs or incorporate them into the binary (if I'm building static with the correct command line options)? Sorry to ask so many questions, but I've had no experience in C or C++.

Static Version Built?
by Hal Vaughan 15 Mar '06

15 Mar '06

Okay, I think I have a static version of Stunnel now. Thanks to help and answers from Jan and Keven! I did this: ./configure --with-ssl=/usr --enable-static --disable-shared --disable-libwrap I'm not sure about the "--with-ssl" option, but it didn't seem to want to work without it. So I have a few questions: 1) How can I be sure it is static? 2) If it isn't static and I run it on a system that does not have all it needs, will it give me errors immediately, or only if a subroutine needs a library that isn't there. 3) Does the "--disable-libwrap" or anything else remove any features? 4) Does using the "--with-ssl" option make it use the libs on my system and make it non-static? 5) My "best guess" is that to install a static version, I just copy over the files src/stunnel and src/libstunnel.la to /usr/bin and /usr/lib, respectively. Is that right? (And, of course, copy man files to the right place.) Thanks -- I hope I'll be done with all these questions soon. Hal

I think it has to do with file_putline not being passed the output file name. Anyone else seeing this behavior? -- Chris

What is "lwrap"? (compiling problem)
by Hal Vaughan 15 Mar '06

15 Mar '06

I keep getting a message: /usr/bin/ld: cannot find -lwrap when I try make. I had to use: ./configure --with-ssl=/usr and it worked, but I keep getting the above error message. I've Googled for it and it seems to reference an SSL library, but it looks like I've got them all installed (unless it needs Python SSL libraries). Thanks! Hal

SSL Libraries on Debian
by Hal Vaughan 14 Mar '06

14 Mar '06

I tried compiling Stunnel on Debian and get an error -- I need the ssl libraries. I tried ./configure --with-ssl=/usr/lib/ssl, which is where libssl-dev was installed, and it doesn't help. There is a libssl file in /usr/lib, but --with-ssl=/usr/lib/ssl doesn't seem to work either. What package on Debian provides the needed headers (according to aptitude, libssl-dev, the one I installed, does, but experience is telling me otherwise). (This, btw, is why I am trying to make static binaries -- you can never tell what to expect on Linux systems at this point. Often config/make doesn't work and there are many times when packages don't work out for one reason or another.) Thanks for any help on this. Hal

Static Binaries for Linux? (Didn't get answer previously)
by Hal Vaughan 13 Mar '06

13 Mar '06

I've brought this up before and didn't get ANY answer at all, and I'm sure someone involved with Stunnel would at least know if what I'm asking is possible. I know help is given on a volunteer basis, so if someone could help me figure this out, it would be a huge help. So far I've spent over a week on getting Stunnel or another program to do the job and if I can't get this to work, I need to just drop Stunnel and figure out how to do the same thing in Java. So thanks for any help. I may need to include Stunnel with my application so my clients behind restrictive firewalls can still enable me to work on their systems with RealVNC. I'm working with clients on both Windows and Linux. Is there a way to get static binaries for Linux? I don't know C or C++ or much more than running ./configure && make && make install. I'd like to know if it is possible or what is needed to create static binaries of the files so I could easily install stunnel on any Linux system by just copying over the proper files. Also, what archive format does the Windows installer use? I'd like to do something similar for Windows, so if I could pull the files out of the installer and copy them over myself, it would be a huge help. Thanks! Hal
