greetings. clients connects normally when not using ssl (stunnel). when using ssl the connection on the client end appears to take about a minute but does eventually work (mail is sent through encrypted). shown below is the log with debug=7 and a space between the area where a "pause" seems to be, ideas on what could be occurring during this time to induce the "pause"? client = machine making connection. server = machine running stunnel accepting the connection. 2007.02.14 12:24:06 LOG7[69377:134631424]: imaps accepted FD=9 from client:62847 2007.02.14 12:24:06

"The most recent stable Stunnel version?"
by Roger Fulton 04 Feb '07

04 Feb '07

Hi, I've checked the support pages. I've browsed the mailing list archives. I've perused the ChangeLog file. I can't find an answer to this question: At http://www.stunnel.org/download/binaries.html is stated "The most recent stable Stunnel version is flagged with a red asterisk (*)." I've used two different browsers, and I'll be danged if I see *any* version marked with *any* asterisk, red or otherwise. Would someone kindly direct this Stunnel newbie to the "most recent stable Stunnel version?" TIA.

Oracle JDBC Failover not working
by Dario Mariani 02 Feb '07

02 Feb '07

Hi all. We have a problem here with this configuration. before stunnel: BEA Weblogic, 2 JDBC, server1:1521 and server2:1521 Two SunCluster nodes with Oracle OPS/RAC (active-active conf), with NO shared address. So "server1" and "server2" are the phisical address. after stunnel: the JDBC config is 127.0.0.1:10001 and 127.0.0.1:10002 stunnel client is 10001->server1:11521 and 10002->server2:11521 stunnel server is 11521->localhost:1521 When we shut down the server1 (so oracle, listener and stunnel server is not responding), BEA cannot failover. A quick analisys shows that: 1. the JDBC connects to stunnel client, that accept the connection 2. stunnel client fails to connect to stunnel server 3. stunnel client close the connection with the JDBC 4. the JDBC cannot deal with the situation and doesn't failover. It seems like JDBC doesn't failover when he can open a connection but oracle doesn't reply. What i need is: is possible for Stunnel client to FIRST try to connect to the server, and then eventually accept the connection from the jdbc? Bye, dario.

Intermediate Cert validation problem
by Eric McCombs 31 Jan '07

31 Jan '07

I'm experiencing a problem validating intermediate cert on our Stunnel configuration. We are using Stunnel to forward IMAP, POP and SMTP SSL ports from our vpn server to our internal mail server. We originally used a self-signed cert on the vpn server. When clients connect via Outlook, Outlook Express, Thunderbird and various cell phone mail programs they received a warning message (Unable to verify identity of xxx) about the self-signed cert. To resolve this issue we purchased a SSL cert from Verisign to install on the vpn server. We generated the key and CSR and received the new cert from Verisign, which also requires an intermediate cert for verification. We have tried various methods to have the certs validated, combining the key, intermediate cert and server cert in one file, pointing to the CA_file, etc. but continue to see the Unable to verify identity message. Has anybody else encountered this problem and found a way to resolve the problem? Thanks in advance. Eric McCombs

To all, Can Stunnel communicate bi-directionally over a single port? Or does it listen on one and communicate on a different one? Thanks Dean

Re: [stunnel-users] How is stunnel started ? / Searching stunnel service name
by Ben Stover 22 Jan '07

22 Jan '07

Hmm that is very curious. I investigated now all runnig services and did not found the stunnel service. The only reason I can find for this is that the service name does not contain "stunnel" in its name. How is it called otherwise? My services here (under Win2000) are (when I type "net start" at the command prompt): Alerter AVK Monitor AVK Service AVKProxy COM+ Event System Computer Browser DHCP Client Distributed Link Tracking Client Event Log IPSEC Policy Agent Logical Disk Manager MGABGEXE Network Connections PDFCreatorMessages PDScheduler Plug and Play Print Spooler Protected Storage Remote Access Connection Manager Remote Procedure Call (RPC) Remote Registry Service Removable Storage RunAs Service Security Accounts Manager Server Still Image Service System Event Notification Task Scheduler TCP/IP NetBIOS Helper Service Telephony Washer AutoComplete Windows Management Instrumentation Windows Management Instrumentation Driver Extensions Workstation Is it IPSEC Policy agent the service for stunnel ?
