Windows setup
by Koenraad Lelong 04 Jul '08

04 Jul '08

Hello, I would like to know if it is possible to run a silent setup of the Windows-setup of stunnel. I'm including it in my own setup of my own application so I would like to avoid the interaction of the stunnel-setup. Second question is if it is bad to "install" stunnel more than once on a computer. Until now I had a setup for new installations and an update for updates of my application. This seems not to work because some users use the setup to update an existing installation and with this they run the install of stunnel for the second time. If it is bad, how do I detect the existance of stunnel, and what version it is, so I could update stunnel if it's outdated. Regards, Koenraad Lelong. P.S. If this is the wrong list for such questions I apologize. I would like to know the right list.

Hi, If anyone have a clue on what I should do to fix this issue, I would really appreciated: One of the stunnel process is running at 99% and in R state and the time just keep incrementing.

protect the private key, while running stunnel in server mode as a windows service
by sandeep siroya 03 Jul '08

Hi, I have stunnel in server mode running as a windows service on a Win2003 Server system. I need to give this system to a different company for testing their client against our server. How do I protect my private key on stunnel, while letting the 3rd company being able to login as administrator on stunnel's win2003 system and start/stop stunnel service? I know one can protect the private key with a passphrase in stunnel, but that does not serve my purpose as stunnel in this case should be able to start/stop without any user-intervention and I cannot store the passphrase in cleartext. thanks , ss

Hello there, I have installed stunnel server on FreeBSD. I configure it like this cert=server_cert.pem key=private\server_key.pem socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 debug = 7 verify=2 CAfile=test_cert.pem [ssl_host_proxy] accept=172.24.150.15:1234 connect=192.168.1.1:10500 TIMEOUTidle=120 Client side is not a computer it's small device. I generate client certificates in this manor: echo off del test_ck.pem /q # delete previous test.ck.pem file echo Starting New test_ck file Generation C:\OpenSSL\bin\openssl.exe req -new -x509 -newkey rsa:2048 -sha1 -out test_cert.pem -keyout test_key.pem -nodes -config sample_ck.cnf -days 1825 -batch C:\OpenSSL\bin\openssl.exe pkcs8 -in test_key.pem -topk8 -out test_pk8.pem -passout pass:"TestPassword0001" -noiter -v1 PBE-SHA1-3DES del test_key.pem /q copy test_cert.pem+test_pk8.pem test_ck.pem /y del test_pk8.pem /q Echo New test_ck.pem file has the following sections: findstr "BEGIN END" test_ck.pem pause test_cert.pem is on a stunnel server as CAfile and test_ck.pem is on my small device which is capable to connect via stunnel. And I generate other self-signed CA, and generate one certificate request and sign it via this CA, and install that key and certificate on server. cert=server_cert.pem key=private\server_key.pem All is working fine, but after one year my server certificate has expired, when I regenerate new server certificate and try to connect, I see in server log this: Child process 6094 finished with code 0 SSL state (accept): before accept initialization SSL state (accept): SSLv3 read client hello A SSL state (accept): SSLv3 write server hello A SSL state (accept): SSLv3 write certificate A SSL state (accept): SSLv3 write server done A SSL state (accept): SSLv3 flush data SSL_accept: Peer suddenly disconnected And my device can't connect to the server, I haven't any client side logs and error messages, only NOT DELIVERED in my device. :( Can you please help me to solve this problem, I am trying many many times, I was very angry.. Thank you very much. Victor Harutyunyan. P.S. Sorry for my bad english.

socket not getting closed
by Manjunath S Karikatti 02 Jul '08

02 Jul '08

Hello, We are using stunnel to wrap the tcp connetion between the our client session used by users and the server process. Due to some reason when client session terminates abruptly (either due to user's PC crash or network outage) the stunnel process does not terminate. We see that the socket on client PC is closed but stunnel process is still alive with socket for that PC in established state. This is on AIX platform. Do not know this is issue with stunnel process or something on AIX needs to be tuned (like the tcp_keepidle value). Thanks for any info and help. Thanks and Regards, Manjunath

Thanks for your reply. I was hoping to see if someone have a similar issue since there was an issue with stunnel 4.20 version.
