Correcting my previous post, > ... one can see an EAGAIN on the -r socket of stunnel. That's not true, the EAGAIN is on the accepted file descriptor. The problem is not solved, though ... Martin.

ssl - excessive message size
by Olivier Rademakers 06 Sep '04

06 Sep '04

Hi All, I am having trouble with a secure connection that used to work until now. I am using an stunnel connection to transfer data from an ldap server(127.0.0.1) to Win Active Directory server (machineB.domain.com) in order to update AD with updated ldap data. I have run stunnel in high verbosity manually so I could extract a log of a connection attempt. Here it is below: # stunnel -c -f -D 7 -P /var/ldapad/ -d 127.0.0.1:6360 -r machineB.domain.com:636 LOG5[9318:1]: Using 'machineB.domain.com.636' as tcpwrapper service name LOG7[9318:1]: RAND_status claims sufficient entropy for the PRNG LOG6[9318:1]: PRNG seeded successfully LOG5[9318:1]: stunnel 3.14 on sparc-sun-solaris2.7 PTHREAD LOG7[9318:1]: Created pid file /var/ldapad/stunnel.machineB.domain.com.636.pid LOG7[9318:1]: machineB.domain.com.636 bound to 127.0.0.1:6360 LOG7[9318:4]: machineB.domain.com.636 started LOG5[9318:4]: machineB.domain.com.636 connected from 127.0.0.1:55001 LOG7[9318:4]: machineB.domain.com.636 connecting 172.27.24.4:636 LOG7[9318:4]: Remote host connected LOG7[9318:4]: before/connect initialization LOG7[9318:4]: before/connect initialization LOG7[9318:4]: SSLv3 write client hello A LOG7[9318:4]: SSLv3 read server hello A LOG7[9318:4]: SSLv3 read server certificate A LOG7[9318:4]: SSLv3 read server key exchange A LOG7[9318:4]: SSLv3 read server key exchange A LOG3[9318:4]: SSL_connect: error:1408E098:SSL routines:SSL3_GET_MESSAGE:excessive message size LOG7[9318:4]: machineB.domain.com.636 finished (0 left) I have searched for this error but to no avail and am wondering if any of you have already come across such, and if so would have the beginning of a solution, and why not The Solution ;-) NB: When running stunnel with the "-c" operand (client mode), it is said the certificates are optional. I have captured the dialogue between the two machines, and apparently, the problem would be coming from the AD server as the DN (Distinguished Name) in the cert is ~8000 bytes long. The capture reveals other errors, checksum and more, so if needed I could append those to the problem stated here. Again, unix-ldap side has not changed to my knowledge. The script has always been the same, and it worked until now. The ldap server is SUN Solaris 2.8 with ssl 0.9.7b Version of stunnel: stunnel 3.21 on sparc-sun-solaris2.8 PTHREAD The AD server is a Windows 2000 machine. Please enlighten me, Olivier

win32 stunnel - quiet service install
by Michael Brown 03 Sep '04

03 Sep '04

Greetings, It would be great if while installing as a service on win32, there was an option to install quietly - i.e. only pop up a dialog box to the user if there's a problem. Any chance of somebody nice compiling me a binary that does this? :) M. -- Michael Brown {0x527670C0} | `One of the main causes of the fall of Systems Administrator | the Roman Empire was that, lacking zero, +1 519 888 7111 x2339 | they had no way to indicate successful michaelb(a)opentext.com | termination of their C programs.' - Firth

I'm totally new to Stunnel, which I'm running on a Windows XP platform. Where can I find a newbie's tutorial, e.g. to tell me what stunnel expects to find in stunnel.conf? Many thanks for your help. -- Bob

Samba and stunnel
by Charles A. Monteiro 01 Sep '04

01 Sep '04

just wondering if anybody has had any difficulties with wrapping samba with stunnel, Sambo 3.0 apparently has dropped the support for ssl and therefore we are now also considering using stunnel to wrap Samba. thanks -Charles -- Using Opera's revolutionary e-mail client: http://www.opera.com/m2/

Marketing Stunnel
by Charles A. Monteiro 01 Sep '04

01 Sep '04

So I now need to sell stunnel to those that make decisions. It would be helpful to get an understanding of how widely deployed it is. It also would be useful to have a number of company names that I could drop, especially if said companies were major corporations and especially if they were players in the finance/banking industry. thanks in advance, -Charles -- Using Opera's revolutionary e-mail client: http://www.opera.com/m2/

You still use passwords! 8-) I'm currently in the process of moving everything over to keypairs. I'm not blessed with security conscious users, and it's hard to get them to understand that a keypair is actually more convenient (especially if you use an agent). :) > > I recommend to use CAfile instead of CApath for simple configurations. > > It doesn't need a hashed directory and is not relative to chroot jail. > > So something like: > > CApath = /var/stunnel/certs > No! > CAfile = /var/stunnel/certs/your_cert.pem Oops, yeah I see what you mean. > I'm paranoid that someone has been at my testing configs now. :) I > previously had a working setup, which worries me even further as I *did* > use a symlink. Yes, you can use symlinks, but instead of: ln -s /a/b/c/x /a/b/c/y use: cd /a/b/c ln -s x y Please notice (ls -l) the results are not the same!
