Dynamic hosts
by Terry Riegel 23 Jun '09

Hello, I have just set up stunnel to allow unsecured client pop3 connections to my secured pop3 server chroot = /stunnel/ pid = /stunnel.pid setuid = www setgid = www client = yes foreground=yes [995] accept = localhost:10110 connect = mail.clearimageonline.com:995 And it works as expected. Is there a way to set it up so it can dynamically connect to any server. Something like... connect = *:995 I was able to start a new instance of stunnel with a separate config file but this seems inefficient as it starts up 6 processes each time. What I would like to do is dynamically add/subtract servers that it can connect to. My goal here is to build a webmail client that can use stunnel to do the secure connections to either POP or IMAP servers. My client software uses unsecured sockets. Any help would be greatly appreciated. Terry Riegel

Install, Starting & Using Stunnel on OS X (more)

Hi, I forgot a few things in my last msg, that were implied but not explicitly stated. 1.) I downloaded and installed stunnel-4.27. 2.) Im not running darwin ports. 3.) When I installed I entered the commands on the command line without ever touching xCode. 4.) I am running MAC OS 10.5.7. I will have to do a later install on MAC OS 10.4.11. 5.) I need to connect my laptop (test machine) to an ldap server. The ldap server is NOT running stunnel, and I have no control over the ldap server. I am wanting to create a secure connection from my machine to the target server. +++++++++++++++++++++ Previous Msg Below. +++++++++++++++++++++ Hi I'm a newbie to stunnel. I have a couple of questions....ok, a zillion. However I'll stick to the basics. I found this in the archives that apply to my situation: http://marc.info/?l=stunnel-users&m=121848237124000&w=2 I followed those instructions that Tom Shaw gave, and I can't tell whether or not this thing is installed at all. http://marc.info/?l=stunnel-users&m=121848703131936&w=2 I think that the files are in the right places.

However, I also see that its throwing an error about the PEM file, that it thinks that its not there. Is there any way to check to see if its pointing at the right file for the pem ? Or to use another crt file ? Now the question becomes how the hell do I start this thing ? (I'm running leopard [10.5.7] for test purposes, but I'll have to do this all over again for a tiger install [10.4.11]...) Then once I get it started, how the hell do I initiate what needs doing ?

4.26 works OK, 4.27 will not POP email
by Jeff Salisbury 14 Jun '09

14 Jun '09

Greetings, We have been using Stunnel 4.26 to facilitate the sending and receiving of email with an email client that is not SSL enabled. Version 4.26 has been working great. However, when we upgrade to 4.27, we are unable to POP email (we can send email). We did not change our Stunnel.conf file. Can anyone advise us what we need to do to get 4.27 working? I've included our Stunnel.conf file contents, and the Stunnel log output below.

Hello Carter, thank you very much for your help and nice examples. I will try it in my local network. Have a good day. Mia ---- Pôvodná správa ---- Od koho: Carter Browne <cbrowne(a)cbcs-usa.com> Komu: aaa aaa <miamia(a)inMail.sk> Dátum: 8. 6. 2009 17:52:00 Predmet: Re: [stunnel-users] 1 server and more desktops Mia, I work in both Windows and Linux, so I use a Windows approach - copying files where in Linux a link would be more appropriate. Assume server.pem is the server full server certificate including the private key and client1.pem is a full client certificate including the key. The first step is to make a copy of the server certificate and delete the lines starting with -----BEGIN RSA PRIVATE KEY------ down through the blank line after -----END RSA PRIVATE KEY----- Initial I call this server-pub.pem The command: openssl x509 -in server-pub.pem -subject_hash -noout will print out the hash for the server key (as 8 hexadecimal digits), for example abcef012 Then I rename server-pub.pem to abcdef012.0 I repeat the same process for each client key, so that client1.pem in this example would have a public key named 987654fe.0 (assuming that the hash of 987654fe). In the client1 configuration: cert = client1.pem key = client1.pem verify = 3 cafile = abcdef012.0 In the server configuration cert = server1.pem key = server1.pem verify = 3 capath = capath In the capath directory is 987654fe.0 ... Plus the hashes of the other clients. In Windows, the capath is under the stunnel directory. The client certificates can also be concatenated in a single file. If you use a directory, it is not necessary to restart stunnel if you add a new client. If you use a concatenated file, you do have to restart stunnel if you add a client. There are some notes in the documentation about the structure of a concatenated file. I hope this helps.

Hi Carter, thank you. I am trying to use scenario with self-signed certificates exactly like you are using it. Could you please write me some examples of config for server and clients? I don't know where to put private keys and how to set up server for acceptation of certificates from clients only - server must reject all communication without/or with other certificates as are stored in his folder. thank you in advance regards, mia > ---- Pôvodná správa ---- > Od koho: Carter Browne <cbrowne(a)cbcs-usa.com> > Komu: aaa aaa <miamia(a)inMail.sk> > Dátum: 8. 6. 2009 15:00:00 > Predmet: Re: [stunnel-users] 1 server and more desktops > > I do this using self-signed certificates and verify=2 or verify=3.

Stunnel client hangs in background mode when smartcard is used
by John Abloyer 08 Jun '09

08 Jun '09

Hi! I have a problem when running ssh over stunnel in background mode ('foreground' out-commented in config file). In foreground mode, everything works fine. I'm using a modified OpenSSL, adding an engine that is dedicated to communicate with a smartcard reader. The scenario is: - Starting stunnel on server, extract from config file: [ssh] accept = myserver:122 connect = 22 - Starting stunnel on client, extract from config file: engine = myengine engineNum = 1 client = yes [ssh] accept = 22 connect = myserver:122 I come to here, than it hangs: ... 2009.06.08 15:08:22 LOG7[472:3054680976]: SSL state (connect): SSLv3 read server certificate A 2009.06.08 15:08:22 LOG7[472:3054680976]: SSL state (connect): SSLv3 read server certificate request A 2009.06.08 15:08:22 LOG7[472:3054680976]: SSL state (connect): SSLv3 read server done A 2009.06.08 15:08:22 LOG7[472:3054680976]: SSL state (connect): SSLv3 write client certificate A 2009.06.08 15:08:22 LOG7[472:3054680976]: SSL state (connect): SSLv3 write client key exchange A - - - - - - - But when I run in foreground mode, it all works fine and stunnel continues and I get the ssh login prompt. I'm running RHEL 5.2, OpenSSL 0.9.8*, stunnel 4.27 Any help would be appreciated Rgds JA
