problem with -fd option on Linux
by Sorkin, David 21 Nov '09

21 Nov '09

I'd like to report an interesting problem I found that occurs on Linux but not Solaris when using the -fd 0 option to read the stunnel configuration in from stdin. I am using stunnel to establish client tunnels on the fly for one time use by programs such as rsync. The client config file is generated automatically with some dynamic parameters. After the client tunnel is established a client program connects to the specified port on localhost. This works fine on Solaris but on Linux I found that the client program has to be invoked *twice* before it works. My work around is to write the config to a temp file and starting stunnel with the location of the file as its argument instead of writing to its standard input. I am using tcp wrappers to protect the stunnel servers and to limit the connects to the client to localhost. This isn't an issue for me anymore but it took a bit of troubleshooting to figure out. On Solaris I am running the same version of stunnel, openssl, etc... all compiled very similarly. One difference could be iconv but I don't know enough about it to say.

The examples at: http://www.stunnel.org/examples/ appear to be for version 3. This wasted a lot of my time.

Hello, I have a problem ... on my network i have more than one proxy server, and y use Stunnel for a remote RDP. if my computer is directly connected to internet there is no problem. If i connect my computer on my domain with my proxies servers i'm not able to connect me on RDP to my remote RDP server. Is it possible to indicate my proxy server to user ?

Error installing Stunnel-4.28
by th＠ftlabs.com 13 Nov '09

13 Nov '09

I could not get Stunnel-4.27 to work as described in a previous post on Mon Nov 9 17:12:38 CET 2009 to which nobody responded. So I tried installing the latest version, Stunnel-4.28, and received the following error when running the 'make' command... options.c: In function ‘service_options’: options.c:1139: error: ‘SSL_OP_NO_TICKET’ undeclared (first use in this function) options.c:1139: error: (Each undeclared identifier is reported only once options.c:1139: error: for each function it appears in.) options.c: In function ‘parse_ssl_option’: options.c:1709: error: ‘SSL_OP_NO_TICKET’ undeclared (first use in this function) make[1]: *** [options.o] Error 1 make[1]: Leaving directory `/tmp/stunnel-4.28/src' make: *** [all-recursive] Error 1 The output for 'openssl version' is: OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 Can anyone help me with either problems please?

Re: [stunnel-users] stunnel-users Digest, Vol 64, Issue 8
by Michael Wilson 12 Nov '09

12 Nov '09

Thanks Ludholf, Re Q2 - Solved. Re Q1 - Thanks, but I should have been clearer, I wanted an automated solution. My nightly Blat e-mails come from a command line .cmd file. I have recently added a javascript to check if stunnel is active and, if not, start it before my e-mails. Now I would like to create a similar script that, if stunnel is running, stops it after my e-mail. I may just have to use Windows Script Host's Terminate.

Vista questions
by Michael Wilson 11 Nov '09

11 Nov '09

I am running 4.27 on Vista and can successfully start it and use Blat to e-mail via my gmail account using stunnel. However, I have two questions: Q1: I would like to close down stunnel after sending my e-mails. How can I do that on Vista? Q2: Why do I get the following when I enter "stunnel -help" at the command line A window with the heading "Stunnel 4.27 on Win32 (not configured)" that says: Stunnel server is down due to an error. You will need to exit and correct the problem Click OK to see the error log window The error log is: Global options compression = zlib|rle compression type debug = [facility].level (e.g. daemon.info) EGD = path to Entropy Gathering Daemon socket engine = auto|engine_id engineCtrl = cmd[:arg] output = file to append log messages RNDbytes = bytes to read from random seed files RNDfile = path to file with random seed data RNDoverwrite = yes|no overwrite seed datafiles with new random data service = service name socket = a|l|r:option=value[:value] set an option on accept/local/remote socket taskbar = yes|no enable the taskbar icon Service-level options accept = [host:]port accept connections on specified host:port CApath = CA certificate directory for 'verify' option CAfile = CA certificate file for 'verify' option cert = certificate chain ciphers = list of permitted SSL ciphers client = yes|no client mode (remote service uses SSL) connect = [host:]port connect remote host:port CRLpath = CRL directory CRLfile = CRL file delay = yes|no delay DNS lookup for 'connect' option engineNum = number of engine to read the key from failover = rr|prio chose failover strategy ident = username for IDENT (RFC 1413) checking key = certificate private key local = IP address to be used as source for remote connections ocsp = OCSP server URL OCSPflag = OCSP server flags options = SSL option set an SSL option protocol = protocol to negotiate before SSL initialization currently supported: cifs, connect, nntp, pop3, smtp protocolAuthentication = authentication type for protocol negotiations protocolHost = host:port for protocol negotiations protocolPassword = password for protocol negotiations protocolUsername = username for protocol negotiations session = session cache timeout (in seconds) stack = thread stack size (in bytes) sslVersion = all|SSLv2|SSLv3|TLSv1 SSL method TIMEOUTbusy = seconds to wait for expected data TIMEOUTclose = seconds to wait for close_notify (set to 0 for buggy MSIE) TIMEOUTconnect = seconds to connect remote host TIMEOUTidle = seconds to keep an idle connection verify = level of peer certificate verification level 1 - verify peer certificate if present level 2 - require valid peer certificate always level 3 - verify peer with locally installed certificate 2009.11.11 13:03:36 LOG3[5440:5128]: Server is down

I just installed Stunnel-4.27 on a Linux box and cannot get it to start with a test config that works on another box running same version of Stunnel. I get the following output... [root@dvl stunnel]# stunnel stunnel.conf-test 2009.11.07 11:07:43 LOG7[31671:46968864029472]: Snagged 64 random bytes from stunnel-test.rnd 2009.11.07 11:07:43 LOG7[31671:46968864029472]: Wrote 1024 new random bytes to stunnel-test.rnd 2009.11.07 11:07:43 LOG7[31671:46968864029472]: RAND_status claims sufficient entropy for the PRNG 2009.11.07 11:07:43 LOG7[31671:46968864029472]: PRNG seeded successfully 2009.11.07 11:07:43 LOG7[31671:46968864029472]: SSL context initialized for service Test 2009.11.07 11:07:43 LOG3[31671:46968864029472]: FIPS_mode_set: 2D06C06E: error:2D06C06E:FIPS routines:FIPS_mode_set:fingerprint does not match Does anybody have a clue what may be causing this and how to fix it? Please pardon my ignorance regarding OpenSSL.

Update docs to remove RLE as compression choice
by Joe Kemp 06 Nov '09

06 Nov '09

I just confirmed that RLE compression is not truly implemented in OpenSSL. It would be helpful to remove it from the stunnel docs so people don't think it's an option to compress data. ZLIB is it. And yes I spent a good bit of time last year with Wireshark to determine RLE vs ZLIB compression ratios in stunnel. Shockingly ZLIB was always better... One other note that may be important for some people is that 0.9.7 openssl is not compatible with 0.9.8 with respect to zlib compression. Joe A.
