Certificate chain not used for server?
by Ed Kapitein 21 Mar '05

21 Mar '05

Hi all, I have a working setup of stunnel listening on port 443 and connect to the server on the same host on port 80. It is done via xinetd. Alltough everything is working just fine, clients on webbrowsers get the "you have choosen not to trust this CA" error when connecting to this server. In apache the certificate chain (bundle.ca) is used and clients connecting to the apache server wont get this error. Is there a way to make stunnel behave like apache, so the clients don't have to manually install the CA certificates? (the certificate is a vallid certificate obtained from globaslsign.be) i do have the CAfile in my options file, but this does not help. All help is greatly appreciated! Kind regards, @

Hi all, I have take over a stunnel install and all the clients certs have expired. I have been trying for the past 2 days to get the new step up to work but no such luck. Here is the error I get on the sever side, Linux Fedora Core 3, Stunnel 4.05: 2005.03.17 11:36:15 LOG7[12746:3086949296]: school4 started 2005.03.17 11:36:15 LOG5[12746:3086949296]: school4 connected from XXX.XXX.XXX.XX:1414 2005.03.17 11:36:15 LOG7[12746:3086949296]: SSL state (accept): before/accept initialization 2005.03.17 11:36:15 LOG7[12746:3086949296]: waitforsocket: FD=7, DIR=read 2005.03.17 11:36:15 LOG7[12746:3086949296]: waitforsocket: ok 2005.03.17 11:36:15 LOG7[12746:3086949296]: SSL state (accept): SSLv3 read client hello A 2005.03.17 11:36:15 LOG7[12746:3086949296]: SSL state (accept): SSLv3 write server hello A 2005.03.17 11:36:15 LOG7[12746:3086949296]: SSL state (accept): SSLv3 write certificate A 2005.03.17 11:36:15 LOG7[12746:3086949296]: SSL state (accept): SSLv3 write certificate request A 2005.03.17 11:36:15 LOG7[12746:3086949296]: SSL state (accept): SSLv3 flush data 2005.03.17 11:36:15 LOG7[12746:3086949296]: waitforsocket: FD=7, DIR=read 2005.03.17 11:36:18 LOG7[12746:3086949296]: waitforsocket: ok 2005.03.17 11:36:18 LOG7[12746:3086949296]: SSL alert (read): fatal: certificate unknown 2005.03.17 11:36:18 LOG3[12746:3086949296]: SSL_accept: 14094416: error:14094416:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate unknown 2005.03.17 11:36:18 LOG7[12746:3086949296]: school4 finished (0 left) And here is the output on the client side: 005.03.17 11:21:02 LOG5[952:1264]: stunnel 4.04 on x86-pc-mingw32-gnu WIN32 with OpenSSL 0.9.7 31 Dec2002 2005.03.17 11:21:03 LOG5[952:896]: Peer certificate location (null) 2005.03.17 11:21:03 LOG5[952:896]: WIN32 platform: 30000 clients allowed 2005.03.17 11:21:03 LOG5[952:1152]: schools connected from 127.0.0.1:1413 2005.03.17 11:21:07 LOG5[952:1152]: VERIFY OK: depth=1, /C=CA/ST=XXX/L=XXX/O=XXX/OU=XXX CACERT/CN=sd.traf.mb.ca/emailAddress=sysadmin@XXXX 2005.03.17 11:21:07 LOG4[952:1152]: VERIFY ERROR ONLY MY: no cert for /C=CA/ST=XXX/O=XXXX/OU=STUNNEL SERVER CERT/CN=XXXXX/emailAddress=sysadmin@XXXX 2005.03.17 11:21:07 LOG3[952:1152]: SSL_connect: 14090086: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed I have created the certs on both server and client according to the documents at http://www.stunnel.org/faq/openssl_stunnel_ServerClientAuth.txt. I have the cacert.pem file on the cleint side, I have c_hashed the cert file on the server side. Do I need to out the c_hash of the server side cert on the client as well? Is there something I have missed? Any ideas as to what I can check to see where the issue is? I am desperate, any help would be greatly appreciated.

Creating a man in middle attack for legit purposes.

So I don't normally start off on a list by immediately asking a question but I've got a weird one here that's a critical thing tonight, plus, this might just be entertaining! Problem : MacOS Panther has horrible performance problems with large https web apps. So I setup Stunnel to take port 80 and run it through the web app on 443. Provides http from an https server. On a MacOS client machine I set /etc/hosts to say that system.netsuite.com, the web app, is 192.168.0.4, a handy FreeBSD 5.3 box running stunnel 4.05 It works. Sort of. Problems - the web app keeps rewriting the url from http to https, anytime I click on anything, hmmm.. so I can't make stunnel answer on 443 because then I'm back to square one. Also, I can't login, the web app is giving me a login page as http, but I get a session timeout,please login again, just repeats, unsure if something in the stunnel config should be done to fix that. Other than that, this is working. Config is currently this. client=yes accept=80 connect=system.netsuite.com:443 Anyway, so is this maybe one of the stranger uses of stunnel, possibly a wrong headed and broken way of using it, but oh well. There goes my plea for some ideas on this one, Thanks, Todd

Hi, someone could help me? I am using stunnel (4.07) as ssl client to do telnet to my router with ssl server (openssl 0.9.7d). Stunnel is configured in this way: ========================== client = yes debug=7 cert=clcert.pem [telnet] accept = 23 connect = 10.36.3.144:4433 ========================== My router's configuration is: ========================== -Verify 4 -cert cert.pem ========================== The exchange of packets: ========================== client sends=======> Client Hello server sends======> Server Hello,Certificate, Certificate Request,Server Hello Done client sends======> Certificate, Client Key Exchange, Certificate Verify, Change Cipher Spec, Encrypted Handshake Message server sends=====> Change Cipher Spec, Encrypted Handshake Message and then Application Data. After sending a number of Application Data by the server, client sends Encrypted Alert and closes the connection. Having debug on stunnel client I can see: >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 2005.03.15 11:13:44 LOG5[2040:3964]: stunnel 4.07 on x86-pc-mingw32-gnu WIN32+IPv6 with OpenSSL 0.9.8-dev XX xxx XXXX 2005.03.15 11:13:44 LOG7[2040:2376]: Snagged 64 random bytes from C:/.rnd 2005.03.15 11:13:44 LOG7[2040:2376]: Wrote 1024 new random bytes to C:/.rnd 2005.03.15 11:13:44 LOG7[2040:2376]: RAND_status claims sufficient entropy for the PRNG 2005.03.15 11:13:44 LOG6[2040:2376]: PRNG seeded successfully 2005.03.15 11:13:44 LOG7[2040:2376]: Certificate: clcert.pem 2005.03.15 11:13:44 LOG7[2040:2376]: Key file: clcert.pem 2005.03.15 11:13:44 LOG5[2040:2376]: No limit detected for the number of clients 2005.03.15 11:13:44 LOG7[2040:2376]: FD 188 in non-blocking mode 2005.03.15 11:13:44 LOG7[2040:2376]: SO_REUSEADDR option set on accept socket 2005.03.15 11:13:44 LOG7[2040:2376]: telnet bound to 0.0.0.0:23 2005.03.15 11:13:54 LOG7[2040:2376]: telnet accepted FD=192 from 127.0.0.1:1589 2005.03.15 11:13:54 LOG7[2040:2376]: FD 192 in non-blocking mode 2005.03.15 11:13:54 LOG7[2040:2376]: Creating a new thread 2005.03.15 11:13:54 LOG7[2040:2376]: New thread created 2005.03.15 11:13:54 LOG7[2040:3588]: telnet started 2005.03.15 11:13:54 LOG5[2040:3588]: telnet connected from 127.0.0.1:1589 2005.03.15 11:13:54 LOG7[2040:3588]: FD 224 in non-blocking mode 2005.03.15 11:13:54 LOG7[2040:3588]: telnet connecting 10.36.3.144:4433 2005.03.15 11:13:54 LOG7[2040:3588]: connect_wait: waiting 10 seconds 2005.03.15 11:13:54 LOG7[2040:3588]: connect_wait: connected 2005.03.15 11:13:54 LOG7[2040:3588]: Remote FD=224 initialized 2005.03.15 11:13:54 LOG7[2040:3588]: SSL state (connect): before/connect initialization 2005.03.15 11:13:55 LOG7[2040:3588]: SSL state (connect): SSLv3 write client hello A 2005.03.15 11:13:55 LOG7[2040:3588]: SSL state (connect): SSLv3 read server hello A 2005.03.15 11:13:55 LOG7[2040:3588]: SSL state (connect): SSLv3 read server certificate A 2005.03.15 11:13:55 LOG7[2040:3588]: SSL state (connect): SSLv3 read server certificate request A 2005.03.15 11:13:55 LOG7[2040:3588]: SSL state (connect): SSLv3 read server done A 2005.03.15 11:13:55 LOG7[2040:3588]: SSL state (connect): SSLv3 write client certificate A 2005.03.15 11:13:55 LOG7[2040:3588]: SSL state (connect): SSLv3 write client key exchange A 2005.03.15 11:13:55 LOG7[2040:3588]: SSL state (connect): SSLv3 write certificate verify A 2005.03.15 11:13:55 LOG7[2040:3588]: SSL state (connect): SSLv3 write change cipher spec A 2005.03.15 11:13:55 LOG7[2040:3588]: SSL state (connect): SSLv3 write finished A 2005.03.15 11:13:55 LOG7[2040:3588]: SSL state (connect): SSLv3 flush data 2005.03.15 11:14:26 LOG7[2040:3588]: SSL state (connect): SSLv3 read finished A 2005.03.15 11:14:26 LOG7[2040:3588]: 1 items in the session cache 2005.03.15 11:14:26 LOG7[2040:3588]: 1 client connects (SSL_connect()) 2005.03.15 11:14:26 LOG7[2040:3588]: 1 client connects that finished 2005.03.15 11:14:26 LOG7[2040:3588]: 0 client renegotiatations requested 2005.03.15 11:14:26 LOG7[2040:3588]: 0 server connects (SSL_accept()) 2005.03.15 11:14:26 LOG7[2040:3588]: 0 server connects that finished 2005.03.15 11:14:26 LOG7[2040:3588]: 0 server renegotiatiations requested 2005.03.15 11:14:26 LOG7[2040:3588]: 0 session cache hits 2005.03.15 11:14:26 LOG7[2040:3588]: 0 session cache misses 2005.03.15 11:14:26 LOG7[2040:3588]: 0 session cache timeouts 2005.03.15 11:14:26 LOG6[2040:3588]: SSL connected: new session negotiated 2005.03.15 11:14:26 LOG6[2040:3588]: Negotiated ciphers: AES256-SHA SSLv3 Kx=RSA Au=RSA Enc=AES(256) Mac=SHA1 2005.03.15 11:14:41 LOG7[2040:3588]: SSL alert (write): fatal: bad record mac 2005.03.15 11:14:41 LOG3[2040:3588]: SSL_read: 1408F455: error:1408F455:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac 2005.03.15 11:14:41 LOG5[2040:3588]: Connection reset: 17 bytes sent to SSL, 190 bytes sent to socket 2005.03.15 11:14:41 LOG7[2040:3588]: telnet finished (0 left) >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> This client is now running using an updated library: libeay32.dll obtained compiling openssl-SNAP-20050304 that seemed to be the solution of the problem (after searching on Internet I deduce that).

Radius over Stunnel??
by Frazer, Andrew non Unisys 08 Mar '05

08 Mar '05

Hello all.. I would like to pass radius over stunnel, but I'm not sure if this will work... I have a lot of 'client's that are using RADIUS for authentication, but i want to pass the data over the internet, and radius is relatively insecure. My client machines also run a web server, which stunnel sits in front of, to provide ssl encrypted web services. My radius servers can easily run stunnel, without any issue. Could someone suggest a configuration for this??

syslog question
by Brian T 04 Mar '05

04 Mar '05

If debug=4 ( or not 0 ) and output= is commented in an stunnel config, it looks like in server mode, messages goto syslog. But in client mode, nothing goes to syslog. Is this the way it's supposed to be? -Brian

Re: [stunnel-users] long delay to close the ssl session ?
by ikeda＠areabe 04 Mar '05

If TIMEOUTclose value is positive, stunnel does not transmit TCP FIN, even though application sends TCP FIN, until timeout time expires I don't know why stunnel designer chose it, maybe because of the performance, or some others. Some of the browsers do not start to display the page until receiving the entire packet. And one of the trigger for the browser to detect to receive the whole is TCP FIN. From that things, such kind of the problem of yours occurs. regards taka On Fri, 4 Mar 2005 10:39:47 -0800 (PST), gary ng <garyng2000(a)yahoo.com> wrote: > Thanks, that did the trick.
