Using a signed *.domain.com with ssl - Getting "unable to get local issuer certificate"
by Pritesh Mehta 24 May '06

24 May '06

Hello all, I have had a good hunt around and am having trouble finding a solution. I am using stunnel to provide encrypted pop3 access to our mail server, and we have recently purchased a signed *.XXX.com certificate from godaddy. This has been great since I can use the same cert on all our servers, and this has worked cleanly with the webservices. However, I am having some issues with the stunnel and pop3 service. I am not entirely certain whether it is caused by the *.XXX.com certificate (although I think it unlikely) but was hoping someone more knowledgeable could enlighten me? I currently have stunnel configured thusly: stunnel -f \ -A /etc/stunnel/certs/sf_issuing.pem \ -p /etc/stunnel/certs/wildcard.XXX.com.stunnel.pem \ -r 127.0.0.1:110 Unfortunately my users are getting warnings, and using the openssl client I get: $ openssl s_client -connect mail.XXX.com:995 CONNECTED(00000003) depth=1 /C=US/ST=Arizona/L=Scottsdale/O=Starfield Technologies, Inc./OU=http://www.starfieldtech.com/repository/CN=Starfield Secure Certification Authority/emailAddress=practices(a)starfieldtech.com verify error:num=20:unable to get local issuer certificate verify return:0 --- Certificate chain 0 s:/O=*.XXX.com/OU=Domain Control Validated/CN=*.XXX.com i:/C=US/ST=Arizona/L=Scottsdale/O=Starfield Technologies, Inc./OU=http://www.starfieldtech.com/repository/CN=Starfield Secure Certification Authority/emailAddress=practices(a)starfieldtech.com 1 s:/C=US/ST=Arizona/L=Scottsdale/O=Starfield Technologies, Inc./OU=http://www.starfieldtech.com/repository/CN=Starfield Secure Certification Authority/emailAddress=practices(a)starfieldtech.com i:/L=ValiCert Validation Network/O=ValiCert, Inc./OU=ValiCert Class 2 Policy Validation Authority/CN=http://www.valicert.com//[email protected] --- Server certificate -----BEGIN CERTIFICATE----- [snip] -----END CERTIFICATE----- subject=/O=*.XXX.com/OU=Domain Control Validated/CN=*.XXX.com issuer=/C=US/ST=Arizona/L=Scottsdale/O=Starfield Technologies, Inc./OU=http://www.starfieldtech.com/repository/CN=Starfield Secure Certification Authority/emailAddress=practices(a)starfieldtech.com --- No client certificate CA names sent --- SSL handshake has read 2381 bytes and written 340 bytes --- New, TLSv1/SSLv3, Cipher is AES256-SHA Server public key is 1024 bit Compression: NONE Expansion: NONE SSL-Session: Protocol : TLSv1 Cipher : AES256-SHA Session-ID: 4E550C07BDA9661C4B532A28110E5616549CB9FA72D37E5C979E3C6579F8FB99 Session-ID-ctx: Master-Key: 2E588101AA098463FA40C0353009F5842FA19B1C3D48D9A0000EB2E241EFB70BB10D52FE9BC444344D49653B9FEB25F4 Key-Arg : None Start Time: 1148463445 Timeout : 300 (sec) Verify return code: 20 (unable to get local issuer certificate) --- I am positive this must have been covered before somewhere, but I haven't been able to find anything conclusive.

<Stunnel> multiple connection
by aliquippa1 23 May '06

23 May '06

Hello I have problem with stunnel. I want to use feature which I'm not sure if is available. I want to accept connection from a host and then connect to a few hosts. I want to have something like this: accept = xxx.xxx.xxx.xxx:xxxx connect = yyy.yyy.yyy.yyy:yyyy connect = zzz.zzz.zzz.zzz:zzzz connect = vvv.vvv.vvv.vvv:vvv Now I want to get such situation: 1.accept connection from xxx. 2.try to connect to yyy. 3 if it doesn't work try to connect to zzz. 4 if it doesn't work try to connect to vvv. I wonder if it's possible, because if I use stunnel and connect from xxx it connects me only to the first host and when I connect from xxx again it connects me to the second host and after the third trial from xxx it connects me to vvv. Thanx Agnes

stunnel-4.15 segfaulting and looping under FreeBSD-CURRENT
by Michael Weiser 17 May '06

17 May '06

Hi, I've run into the problem mentioned in: > Scott Tuc Ellentuch at T-B-O-H ml at t-b-o-h.net > Fri Apr 21 23:45:11 CEST 2006 > Hi, > I just did a portupgrade in FreeBSD from 4.14 to 4.15, and now it > seems to be looping the command that I asked it, instead of just doing > it once. Has there been an option added I need to tell it to just do > once? > Thanks, Tuc I'm running stunnel in client mode. It execs uucico which receives and sends uucp jobs via stdin/stdout. The first call to uucico actually succeeds. It seems like stunnel is segfaulting and then re-exec-ing when it would normally quit. A core file is created in the current directory. But stunnel never quits and indefinitely continues to re-exec itself. Has there been any progress in solving this problem? -- Thanks, Michael

Thanks a lot! Craig. I use your method: ./configure --prefix=/stunnel2 It seems that installation is successful. It successfully generate a directory ./stunnel2, in which there are six subdirectories: etc lib man sbin share var But when I run stunnel command in the teminal window.

SSL2Proxy
by Steve Cohen 12 May '06

12 May '06

Hello all, I'm tyring to get around content based(notHostBased) int*rn*t cen$0ring. (don't want this page to be indexed with that keyword, so please don't wite it in your response). This is what I need to do: Set Browser on client machine to use <proxyX:port>, but I want content to be encrypted. The proxy is trusted(ownedByMe), everything else in between is not, after the proxy everything is trusted. So this would be the setup: SetupA: ClientBroswer <> STunnelOnRemoteServer <> LocalProxyServerOnSameServer(Squid) <> RestOfTheInternet And NOT this: SetupB: Browser<>LocalSTunnel<>RemoteSTunnel<>Proxy<>RestOfTheInternet Because I don't want any special kind of configuration on the client's local machine except for setting the proxy.(I am currently doing this via ssh tunneling) -I have squid running on remote server listening on 3128 and it works -I have stunnel running on remote server listening on 8686 and forwarding to localhost:3128, -I have Firefox set to use <myServer:8686> as proxy But when trying to use it, Firefox says connection reset.... Please tell me why this is happening and what I need to do. Feel free to make any suggestions you want, I won't be annoyed if you tell me something I already know. Thanks.

I would further like to ask: Is it true that the proper way to get to TLSv1 is to start with SSLv3? Is there a reference that someone can point me at?

client certificate authentication
by Srilalitha Muralidhara(HCL Capital Market Services) 08 May '06

08 May '06

Hi, I am new to stunnel. My application listens on 6 socket ports. External applications either dump data on these socket ports or send requests on these socket ports to receive data. Thus, my application is a server and external applications are clients. We got to authenticate these external applications before accepting the requests/data. So I am planning to use client certificate authentication of stunnel. In this case, should the server have a certificate as well? Will the server be authenticated? Is it necessary for all the external applications to be using the same certificate?

Performance Problems.
by Don Werve 05 May '06

05 May '06

After a fair bit of poking, prodding, and googling, I have yet to find the solution to my problem. So, here goes: stunnel looks to be running slowly. Very slowly. We're starting to analyze it with gprof to see where it spends all of its time when we're trying to do content negotiation, and I've whipped up a quick-and-dirty Ruby script that grabs data from the server and then spits out the performace results; I'm sitting on my own T1, so our connectivity is pretty good. The results with this script are similar with 'delay=yes', 'session=600', and 'compression=zlib'. So, here's what happens when I nab data from our stunnel-ed server with said script (I can supply the script if anyone is interested): #File Size time thrpht time thrprt multiple ---------------------------------------------------------------------- index.html 7k http 0.1548 ( 46k/s) https 0.7449 ( 9k/s) * 4.8131 test1.jpg 1k http 0.0928 ( 12k/s) https 0.6379 ( 1k/s) * 6.8726 test2.jpg 10k http 0.1812 ( 59k/s) https 0.6743 ( 16k/s) * 3.7208 test3.jpg 19k http 0.2236 ( 85k/s) https 0.7677 ( 24k/s) * 3.4338 test4.jpg 53k http 0.5668 ( 94k/s) https 1.1543 ( 46k/s) * 2.0365 test5.jpg 97k http 0.7861 (123k/s) https 2.1974 ( 44k/s) * 2.7954 test6.jpg 214k http 1.4061 (152k/s) https 2.3735 ( 90k/s) * 1.6880 test7.jpg 140k http 0.9434 (149k/s) https 1.9331 ( 72k/s) * 2.0491 test8.jpg 470k http 2.8590 (164k/s) https 3.7696 (124k/s) * 1.3185 ('multiple' is the number of times 'slower' https is versus http). And, here's my stunnel config: *** cert = /etc/certs/combined.pem setuid = nobody setgid = nobody pid = /var/run/stunnel/stunnel.pid socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 debug = 0 output = /var/log/stunnel [https] local = 64.40.110.16 accept = 443 connect = 64.40.110.16:80 TIMEOUTclose = 0 *** So, any ideas why stunnel is working so slowly? I mean, I know there's the overhead of the SSL negotiation, and I've heard some things about a stunnel session cache, but nothing about enabling/using it (unless 'session = something bigger than zero' does so?). Any suggestions to improve performance, especially for large batches of small transfers? Thanks-in-advance! -- Don Werve <donw(a)iradeon.net> Chief Systems Administrator / Systems Architect

Using stunnel to add https support to ONE virtual host
by Gonzalo Diethelm 05 May '06

05 May '06

Hello, I have Apache serving plain http pages for several domains running as virtual hosts on one machine (debian). I know SSL will not work with this setup, and I understand the reasons why (at least I think I do). Let's say the virtual hosts are www.server1.com www.server2.com www.server3.com I would like to use stunnel to add https capabilities to ONE of the virtual hosts (say, www.server3.com). In other words, I would like to configure stunnel in server mode with a certificate file, listening on www.server3.com:443, so that if I use a browser to visit https://www.server3.com/ then stunnel will accept the connection and forward all traffic to www.server3.com:80, letting Apache handle it; in particular, this would have to allow Apache to recognize which of the virtual hosts is being visited; I wouldn't like to have www.server1.com respond to my requests instead of www.server3.com. Is this possible? Any caveats, hints, recommendations? Thanks in advance, and best regards, -- Gonzalo Diethelm gonzalo.diethelm(a)aditiva.com

Re: stunnel 4.15 crashes with vnc server 4.1.1
by Harry Boeck 04 May '06

04 May '06

Hallo stunnel-users, @Michal Trojnara: Thanks for your help, Mike! The solution came overnight when i remembered my own message: > and the screen on the server side should remove the background image > and visual effects). Well: I disabled the desktop modifications in vnc and it runs. Something is incompatible in the stunnel GUI with the removal of global windows GUI behaviour (despite the fact, that i have not a single one of them in use - to the best of my knowledge), what has nothing to do with the dedication of stunnel. Maybe there's a simple GUI message not handled correctly? As this seems to be something common to all windows versions, could this possibly happen in windows xp, too? (I don't use one, so somone would have to investigate this.) It's another motivation to start compiling in cygnus. But unfortunally at this very moment i'm occupied with other tasks. May be some other guy has the fancy to look at this matter... Mit freundlichem Gruß Harry Boeck
