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

Salu2 :D

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 ?

Everyone, With a lot of help from Daniel I got it to work under the new SCO. It takes a few trick: chsysinfo uw7 ./configure --without-zlib --without-threads chsysinfo default make In case anyone else needs to do this :-) Thanks! Eric This email sent by: Eric S.

Re: [stunnel-users] patch: round robin load balancing

This feature is already implemented since version 4.06, 2004.12.26. Here is the relevant frament of ChangeLog: "Multiple connect=host:port options are allowed in a single service section. Remote hosts are connected using round-robin algorithm. This feature is not compatible with delayed resolver." Best regards, Mike

Error I am receiving in stunnel logfile (help please!)
by Eric S. Eberhard 20 Jan '07

20 Jan '07

Hello Everyone, I tried it on 4.3.3 as well with my re-compiled version ... below are all 5 lines in the log file. stunnel 4.16 on powerpc-ibm-aix4.3.3.0 with OpenSSL 0.9.8c 05 Sep 2006 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv4 stunnel connected from 127.0.0.1:37690 remote socket: Addr family not supported by protocol (66) Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket I also recompiled the latest stunnel with and without IPv6 ... same result with IPv6 as with IPv4 and same result with the new version: stunnel 4.20 on powerpc-ibm-aix4.3.3.0 with OpenSSL 0.9.8c 05 Sep 2006 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 stunnel accepted connection from ::ffff:127.0.0.1:59274 remote socket: Addr family not supported by protocol (66) Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket I have been using this for a while but I had to transfer to a new machine (AIX 4.3 to 5.3) and had to recompile my software and get a newer stunnel. I am now on 4.20 I thought it might be related to ipv4 versus ipv6 ... according to AIX documentation I had it set up for ipv4. I tried ipv6 for ducks, no difference. My inetd.conf line is: visanet stream tcp nowait root /visanet/ssl/stunnel stunnel visanet stream tcp6 nowait root /visanet/ssl/stunnel stunnel The second is IPv6. The error is somehow on the remote though. I can connect to the remote with telnet ... just not stunnel. It seems that depending on how inetd is configured, stunnel accepts either the IPv4 or IPv6 whether or not I compil it using USE_IPv6 1 or not ... what am I missing!? I really only need to hack it to connect to this one site, at least for the moment. /visanet/ssl/visanet.conf My .conf file is: output = /tmp/stunnel.log debug = 5 RNDfile = /visanet/ssl/stunnel.rnd RNDoverwrite = yes client = yes connect = ssllab.pgs.wcom.net:443 sslVersion = SSLv2 cert = /visanet/ssl/stunnel.pem EGD = /etc/egd-pool My guess is that this is something really stupid I am doing, but it is not obvious. Any help would be appreciated. I would even take an AIX executable for stunnel that works! Or whatever the correct configure options are. Or???? Thanks, Eric This email sent by: Eric S.

Re: [stunnel-users] How is stunnel started ?

Probably through a Run entry in the registry. You should definitely try to use something like CodeStuff's Starter: http://members.lycos.co.uk/codestuff/ Best regards.
