rsync over stunnel 4
by Steven Timm 23 Sep '04

23 Sep '04

There's an example of rsync over stunnel at http://www.stunnel.org/examples/rsync_mike.html but it appears to be using stunnel 3 syntax. Has anyone successfully made this work using stunnel 4? right now /etc/stunnel.conf is same on client and server, has [rsync] accept = 2222 connect = 873 Steve Timm ------------------------------------------------------------------ Steven C.

Pass phrase dialog
by John Bradley 18 Sep '04

18 Sep '04

When I start stunnel 4.05, I am presented with a dialog that requests that I enter a pass phrase in order to access our private key. Is there anyway to bypass this dialog. I would like to add the pass phrase to the config file, so that the dialog isn't presented. Security isn't an issue. Our config file will be in a secure location. Otherwise, our operations people are going the have to know the pass phrase to start stunnel. Thanks for your help.

unclosed connection issue
by Ken G 15 Sep '04

15 Sep '04

I'm running stunnel 3.xx with thttpd (an embedded http server) on a small embedded machine on a pci card running linux. Establishing ssh, ftp, and http connections and using OpenSSL has all worked fine since they've been installed. I've been experiencing a strange issue. It seems that stunnel fails (somehow) to inform https clients that the connection has been closed. The sequence of events that I'm observing goes like this: T+0.0s: https client initiates request on port 443 (https). T+0.1s: stunnel establishes connection with thttpd on port 80. T+0.4s: thttpd finishes and dies, closing connection with stunnel. T+0.5s: stunnel finishes sending thttpd's output to its client, and then stops, believing that it has finished that connection. If forked, this copy of stunnel dies. The client (internet explorer, firefox, mozilla... doesn't matter) still believes that the connection is active, and waits for additional data. T+10.5s: Roughly 10 seconds later the client decides that the server timed out and displays what has been sent so far, which is the entire page. The only visible symptom is that small webpages seem to take 10 seconds to load. The visible symptom, then, is that webpages below a certain size (where that size is determined by the browser's willingness to refresh its view as data is being sent) take about 10 seconds to load. Is it possible that this behavior is due to stunnel? _______________________________ Do you Yahoo!? Express yourself with Y! Messenger! Free. Download now. http://messenger.yahoo.com

Wish: Option verify service-dependent
by Hans Werner Strube 13 Sep '04

13 Sep '04

With stunnel-4.x, it would be greatly desirable to make the option "verify" (and possibly the related certs) in stunnel.conf service-dependent rather than global. I have not looked at the code sufficiently to determine whether and how this could be possible.

Stunnel-3.26 / OpenSSL 0.9.6m / Solaris / SSL_accept: Peer sudden ly disconnected
by "Kneißl, Martin" 10 Sep '04

10 Sep '04

Hello everybody, I recompiled the newest "traditional" versions of OpenSSL and stunnel on Solaris, Linux, and HPUX. None of the defaults were changed except for --prefix and --openssldir/--with-ssl and --install_prefix Simple tests went through without problems on Linux and HPUX. For Solaris I have a big problem. Any help is appreciated, for example a trustworthy Stunnel-3.26 binary statically linked with OpenSSL 0.9.6m for Solaris 2.6 could also help. Summary ======= Stunnel listens on host medusa 12480 for SSL and forwards plain HTTP to apache on another host (sirius). When I try a HTTPS request to medusa:12480 using a browser or wget, the connection is broken immediately. When stunnel runs under the system call tracer truss the same commands succeed most of the time. In the truss output one can see an EAGAIN on the -r socket of stunnel. That might indicate that there is a problem when TCP buffers do not fill quickly receiving on the -r side. Details ======= Client side: (IP is 192.168.50.153) C:\>wget --spider https://medusa:12480 --12:59:18-- https://medusa:12480/ => `index.html' Resolving medusa... 192.168.41.13 Connecting to medusa[192.168.41.13]:12480... connected.

ssl - excessive message size
by Olivier Rademakers 06 Sep '04

06 Sep '04

Hi All, I am having trouble with a secure connection that used to work until now. I am using an stunnel connection to transfer data from an ldap server(127.0.0.1) to Win Active Directory server (machineB.domain.com) in order to update AD with updated ldap data. I have run stunnel in high verbosity manually so I could extract a log of a connection attempt. Here it is below: # stunnel -c -f -D 7 -P /var/ldapad/ -d 127.0.0.1:6360 -r machineB.domain.com:636 LOG5[9318:1]: Using 'machineB.domain.com.636' as tcpwrapper service name LOG7[9318:1]: RAND_status claims sufficient entropy for the PRNG LOG6[9318:1]: PRNG seeded successfully LOG5[9318:1]: stunnel 3.14 on sparc-sun-solaris2.7 PTHREAD LOG7[9318:1]: Created pid file /var/ldapad/stunnel.machineB.domain.com.636.pid LOG7[9318:1]: machineB.domain.com.636 bound to 127.0.0.1:6360 LOG7[9318:4]: machineB.domain.com.636 started LOG5[9318:4]: machineB.domain.com.636 connected from 127.0.0.1:55001 LOG7[9318:4]: machineB.domain.com.636 connecting 172.27.24.4:636 LOG7[9318:4]: Remote host connected LOG7[9318:4]: before/connect initialization LOG7[9318:4]: before/connect initialization LOG7[9318:4]: SSLv3 write client hello A LOG7[9318:4]: SSLv3 read server hello A LOG7[9318:4]: SSLv3 read server certificate A LOG7[9318:4]: SSLv3 read server key exchange A LOG7[9318:4]: SSLv3 read server key exchange A LOG3[9318:4]: SSL_connect: error:1408E098:SSL routines:SSL3_GET_MESSAGE:excessive message size LOG7[9318:4]: machineB.domain.com.636 finished (0 left) I have searched for this error but to no avail and am wondering if any of you have already come across such, and if so would have the beginning of a solution, and why not The Solution ;-) NB: When running stunnel with the "-c" operand (client mode), it is said the certificates are optional. I have captured the dialogue between the two machines, and apparently, the problem would be coming from the AD server as the DN (Distinguished Name) in the cert is ~8000 bytes long. The capture reveals other errors, checksum and more, so if needed I could append those to the problem stated here. Again, unix-ldap side has not changed to my knowledge. The script has always been the same, and it worked until now. The ldap server is SUN Solaris 2.8 with ssl 0.9.7b Version of stunnel: stunnel 3.21 on sparc-sun-solaris2.8 PTHREAD The AD server is a Windows 2000 machine. Please enlighten me, Olivier

Greetings, It would be great if while installing as a service on win32, there was an option to install quietly - i.e. only pop up a dialog box to the user if there's a problem.

Samba and stunnel
by Charles A. Monteiro 01 Sep '04

01 Sep '04

just wondering if anybody has had any difficulties with wrapping samba with stunnel, Sambo 3.0 apparently has dropped the support for ssl and therefore we are now also considering using stunnel to wrap Samba. thanks -Charles -- Using Opera's revolutionary e-mail client: http://www.opera.com/m2/

Marketing Stunnel
by Charles A. Monteiro 01 Sep '04

So I now need to sell stunnel to those that make decisions. It would be helpful to get an understanding of how widely deployed it is. It also would be useful to have a number of company names that I could drop, especially if said companies were major corporations and especially if they were players in the finance/banking industry. thanks in advance, -Charles -- Using Opera's revolutionary e-mail client: http://www.opera.com/m2/

client auth saga

Frustration doesn't begin to express it! SEC Productions presents: * THE CLIENT AND SERVER AUTH SAGA * lets get on with it: complete walkthrough of ssl cert creation ----------------------------------------- By the way, please don't lecture me on ssh'ing into machines as root, they are located on an isolated network and of course, all logging in as root is disabled when they are put into production. :) There now follows a step by step account of everything so far... command prompt key: ca# = certificate authority machine (or my isolated desktop, whichever you prefer). records# = log server dns# = my dns server (the logging client) (obvious output of scripts snipped) ----------------------------------------- ca# cd /etc/ssl/misc ca# ./CA.sh -newca <snip> ca# ./CA.sh -newreq <snip> Request (and private key) is in newreq.pem ca# ./CA.sh -sign Signed certificate is in newcert.pem ca# cat newreq.pem newcert.pem > log_server.pem Then I realised that I needed it to be passwordless. ca# openssl rsa -in newreq.pem -out decryptedcert.pem ca# cat decryptedcert.pem newcert.pem > log_server_np.pem (log_server_np.pem is now passwordless) ca# scp log_server_np.pem records:/etc/ssl/stunnel_cert/ ca# scp demoCA/cacert.pem dns:/var/stunnel/cert/cacert.pem we'll just try with server side auth at the moment, on the loghost: records# cat /etc/stunnel/stunnel.conf cert = /etc/ssl/stunnel_cert/log_server_np.pem chroot = /var/stunnel pid = /var/run/stunnel.pid CApath = /certs CRLpath = /crls #verify = 2 debug = 7 output = stunnel.log setuid = _stunnel setgid = _stunnel [syslogngs] accept = 192.168.1.9:5514 connect = 127.0.0.1:5515 on the client: dns# cat /etc/stunnel/stunnel.conf #cert = /etc/stunnel/cert/clientkeycert.pem chroot = /var/stunnel pid = /var/run/stunnel.pid CAfile = /certs/cacert.pem CRLpath = /crls debug = 7 output = stunnel.log client = yes setuid = _stunnel setgid = _stunnel [syslogngs] accept = 127.0.0.1:5515 connect = 192.168.1.9:5514 looks good... dns# telnet localhost 5515 (in the interests of patience and readability, the output of stunnel.log isn't posted here, suffice to say the connection is successful and works) now to step up to client and server authentication. ca# openssl req -x509 -newkey rsa:2048 -keyout clientkey.pem -out \ clientcert -days 365 (forgot to use -nodes) ca# openssl rsa -in clientkey.pem -out client_decrypted_key.pem ca# cat clientkey.pem clientcert.pem > clientkeycert.pem ca# ./c_hash clientkeycert.pem 4410a4d9.0 => clientkeycert.pem ca# scp clientkeycert.pem dns:/etc/stunnel/cert ca# scp clientcert.pem records:/var/stunnel/certs on the server: records# ln -s /var/stunnel/certs/clientcert.pem \ /var/stunnel/certs/4410a4d9.0 adjust the stunnel.conf on both hosts accordingly: records# cat /etc/stunnel/stunnel.conf cert = /etc/ssl/stunnel_cert/log_server_np.pem chroot = /var/stunnel pid = /var/run/stunnel.pid CApath = /certs CRLpath = /crls verify = 3 debug = 7 output = stunnel.log setuid = _stunnel setgid = _stunnel [syslogngs] accept = 192.168.1.9:5514 connect = 127.0.0.1:5515 dns# cat /etc/stunnel/stunnel.conf cert = /etc/stunnel/cert/clientkeycert.pem chroot = /var/stunnel pid = /var/run/stunnel.pid CAfile = /certs/cacert.pem CRLpath = /crls debug = 7 output = stunnel.log client = yes setuid = _stunnel setgid = _stunnel [syslogngs] accept = 127.0.0.1:5515 connect = 192.168.1.9:5514 and just to show the permissions: records# ls -al /etc/ssl/ drwx------ 2 _stunnel _stunnel 512 Aug 30 12:19 stunnel_cert records# ls -al /etc/ssl/stunnel_cert -rw------- 1 _stunnel _stunnel 4320 Aug 30 12:19 log_server_np.pem records# ls -al /var/stunnel/certs/ lrwxr-xr-x 1 root _stunnel 33 Aug 30 14:33 4410a4d9.0 -> /var/stunnel/certs/clientcert.pem -rw------- 1 _stunnel _stunnel 1489 Aug 30 14:32 clientcert.pem dns# ls -al /etc/stunnel/dns# ls -al /etc/stunnel/ drwx------ 3 _stunnel _stunnel 512 Aug 29 21:50 . drwx------ 2 _stunnel _stunnel 512 Aug 30 14:18 cert -rw------- 1 _stunnel _stunnel 301 Aug 30 14:22 stunnel.conf -rw------- 1 _stunnel _stunnel 13401 Aug 29 22:21 stunnel.log dns# ls -al /etc/stunnel/cert/ -rw------- 1 _stunnel _stunnel 3168 Aug 30 14:18 clientkeycert.pem dns# ls -al /var/stunnel/ drwx------ 5 _stunnel _stunnel 512 Aug 29 21:28 . drwx------ 2 _stunnel _stunnel 512 Aug 30 13:59 cert drwx------ 2 _stunnel _stunnel 512 Aug 29 21:16 crl drwx------ 3 _stunnel _stunnel 512 Aug 29 21:28 var dns# ls -al /var/stunnel/cert/ drwx------ 2 _stunnel _stunnel 512 Aug 30 13:59 . -rw------- 1 _stunnel _stunnel 1115 Aug 30 13:59 cacert.pem now, to test. records# /usr/local/sbin/stunnel /etc/stunnel/stunnel.conf dns# /usr/local/sbin/stunnel /etc/stunnel/stunnel.conf the log files on both show no errors, lets try a connection from dns to records... dns# telnet localhost 5515 Trying ::1... telnet: connect to address ::1: Connection refused Trying 127.0.0.1...

MySQL client through stunnel on win32
by Rumi Szabolcs 26 Aug '04

26 Aug '04

Hello! I have tried the following setup: server: MySQL 4.0.20 with native OpenSSL 0.9.7d support on Linux client: MySQL 4.0.20 without SSL support, through stunnel 4.0.5 on WinXP As it can be suspected from the above, I was trying to use the mysqld with ssl support directly as the server side of the connection, without stunnel. I saw a pseudo-https client solution in the stunnel docs where this approach seemed to work. The client stunnel.conf: cert = client-test.crt key = client-test.key client = yes debug = debug [mysqlclient] accept = 3306 connect = server.host.fqdn:3306 The mysql client reported the following error, right after asking for the password: ERROR 2013: Lost connection to MySQL server during query Here is the log from the client stunnel: 2004.08.26 17:19:43 LOG5[2396:1256]: stunnel 4.05 on x86-pc-mingw32-gnu WIN32 with OpenSSL 0.9.7d 17 Mar 2004 2004.08.26 17:19:43 LOG7[2396:1908]: RAND_status claims sufficient entropy for the PRNG 2004.08.26 17:19:43 LOG6[2396:1908]: PRNG seeded successfully 2004.08.26 17:19:43 LOG7[2396:1908]: Certificate: client-test.crt 2004.08.26 17:19:43 LOG7[2396:1908]: Key file: client-test.key 2004.08.26 17:19:43 LOG5[2396:1908]: WIN32 platform: 30000 clients allowed 2004.08.26 17:19:43 LOG7[2396:1908]: FD 1828 in non-blocking mode 2004.08.26 17:19:43 LOG7[2396:1908]: SO_REUSEADDR option set on accept socket 2004.08.26 17:19:43 LOG7[2396:1908]: mysqlclient bound to 0.0.0.0:3306 2004.08.26 17:19:52 LOG7[2396:1908]: mysqlclient accepted FD=1836 from 127.0.0.1:3269 2004.08.26 17:19:52 LOG7[2396:1908]: FD 1836 in non-blocking mode 2004.08.26 17:19:52 LOG7[2396:1908]: Creating a new thread 2004.08.26 17:19:52 LOG7[2396:1908]: New thread created 2004.08.26 17:19:52 LOG7[2396:1816]: mysqlclient started 2004.08.26 17:19:52 LOG5[2396:1816]: mysqlclient connected from 127.0.0.1:3269 2004.08.26 17:19:52 LOG7[2396:1816]: FD 1816 in non-blocking mode 2004.08.26 17:19:52 LOG7[2396:1816]: mysqlclient connecting xx.xx.xx.xx:3306 2004.08.26 17:19:52 LOG7[2396:1816]: remote connect #1: EWOULDBLOCK: retrying 2004.08.26 17:19:52 LOG7[2396:1816]: waitforsocket: FD=1816, DIR=write 2004.08.26 17:19:52 LOG7[2396:1816]: waitforsocket: ok 2004.08.26 17:19:52 LOG7[2396:1816]: remote connect #2: EINVAL: ok 2004.08.26 17:19:52 LOG7[2396:1816]: Remote FD=1816 initialized 2004.08.26 17:19:52 LOG7[2396:1816]: SSL state (connect): before/connect initialization 2004.08.26 17:19:52 LOG7[2396:1816]: SSL state (connect): SSLv3 write client hello A 2004.08.26 17:19:52 LOG7[2396:1816]: SSL alert (write): fatal: handshake failure 2004.08.26 17:19:52 LOG3[2396:1816]: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number 2004.08.26 17:19:52 LOG7[2396:1816]: mysqlclient finished (0 left) What is wrong here?
