Re: [stunnel-users] launch stunnel server daemon from php?
by Wesley Kenzie 02 May '08

No, that does not work either. I can get stunnel to start fine outside of php, but not as an exec or shell_exec from within a running script, or even from within php -a interactively. I can get other programs to work fine this way, so it is specific to the stunnel executable as best I can tell. I have tried running various forms of bash scripts too, but none do any better. Ideas? . . . . . Wesley On Fri, May 2, 2008 at 12:52 PM, Ludolf Holzheid < lholzheid(a)bihl-wiedemann.de> wrote: > On Fri, 2008-05-02 12:32:19 -0700, Wesley Kenzie wrote: > > Yes.

Yes. Without this stunnel would not launch. With foreground = no and with the trailing & on the command line I got it to launch, but still control will not return to my php script ... . . . . .

Verify=3 restart needed ?
by Edouard Dessioux 30 Apr '08

30 Apr '08

Hi everyone, Sorry for the repost, but in the web mailing list, my previous message appears weird, so I thought I could re-post it. I'm using stunnel v4.16 on a Windows 2003 Server, and I'm working with stunnel in verify=3 mode. I wanted to know if the stunnel needs to be restarted after a certificates has been removed ? If not, how long is the certificate considered valid after the file has been removed ?

to use certificate and key file in another machine
by Xiaoming Dong 29 Apr '08

29 Apr '08

Stunnel Version 4.2.1 Run in windows 2k3 When I configured stunnel to use cert from another windows machine (I already mapped the drive to this machine). Restarting stunnel got following error: 2008.04.29 10:01:32 LOG7[3568:1792]: Snagged 64 random bytes from C:/.rnd 2008.04.29 10:01:32 LOG7[3568:1792]: Wrote 1024 new random bytes to C:/.rnd 2008.04.29 10:01:32 LOG7[3568:1792]: RAND_status claims sufficient entropy for the PRNG 2008.04.29 10:01:32 LOG7[3568:1792]: PRNG seeded successfully 2008.04.29 10:01:32 LOG3[3568:1792]: V:\Program Files\client_cert\private\client_key.pem: No such process (3) 2008.04.29 10:01:32 LOG3[3568:1792]: Server is down Does anybody have any clue?

Will fwknop work?
by richard.woodman＠cox.net 29 Apr '08

29 Apr '08

If I understand the question correctly, isn't this what "port knocking" or single packet authorization (e.g. fwknop) is supposed to do? I have used fwknop and SSH in our lab, but only with Linux and iptables. However, I think fwknop is supposed to interface with more than just iptables on the local box (meaning you would not have to use a Linux box to replace your current firewall). I think you can use fwknop to monitor syslog and parse for specific events and then open the port. In other words, your current firewall reports to your syslog server and fwknop parses the log file for the security event associated with the reception of a SPA packet on your outside interface. Fwknop then sends your firewall (through a script?) whatever command is required to open the port you want and redirect it to the appropriate inside machine (or you could simply enable / disable a preconfigured rule). I am not a scripting guru so I may be WAY off base here and if I am, I apologize for leading you astray. Anyway, you might want to check out the following: http://cipherdyne.org/fwknop/ --> FireWall KNock Operator home page http://fwknop.darwinports.com/ --> OS X fwknop client There is also a Windows UI version that is supposed to create SPA packets without using fwknop / PERL or running under Cygwin but I have not used that.

how to enable TLS?
by Zhang Weiwu 26 Apr '08

26 Apr '08

Dear all I just configured stunnel for pop+ssl which works fine. What I want is actually smtp+tls. Is there a way to do so? I tried to configure thunderbird to access the port stunnel is listening to, with TLS. Then I got "Connectioin to xxx.xxx.xxx timed out".

Query regarding stunnel performance
by Arati.Kumar＠ubs.com 25 Apr '08

25 Apr '08

Hi, Does anyone know if there are any known issue with stunnel 4.05 and oracle 10g (especially in retrieving blobs) ? . Our application uses stunnel to communicate with oracle database. We are currently experiencing massive performance degradation after upgrading oracle from 9i to 10g (almost 6 times slower from what it was in 9i). Our application stores some data in blobs this seems to be the root cause of slower performance. Pls can someone let me know if there are any known issues with stunnel and 10g blob retrieving ? Also If an upgrade is recommended, which is the stable version we must be switching to?

Linux FIPS compile libary question
by Joe Kemp 23 Apr '08

23 Apr '08

I am compiling stunnel on Centos 5 that has a regular Openssl 0.9.8b rpm installed. I have put my FIPS openssl in /usr/local/sslfips112. Configure with: ./configure --with-ssl=/usr/local/sslfips112 --enable-fips --disable-libwrap Make's linker line: /bin/sh ../libtool --tag=CC --mode=link FIPSLD_CC=gcc /usr/local/sslfips112/bin/fipsld -g -O2 -Wall -Wshadow -Wcast-align -Wpointer-arith -I/usr/local/sslfips112/include -lldap -o stunnel file.o client.o log.o options.o protocol.o network.o resolver.o ssl.o ctx.o verify.o sthreads.o stunnel.o auth.o pty.o libwrap.o -lz -ldl -lutil -lnsl -lpthread -L/usr/local/sslfips112/lib -lssl -lcrypto FIPSLD_CC=gcc /usr/local/sslfips112/bin/fipsld -g -O2 -Wall -Wshadow -Wcast-align -Wpointer-arith -I/usr/local/sslfips112/include -o stunnel file.o client.o log.o options.o protocol.o network.o resolver.o ssl.o ctx.o verify.o sthreads.o stunnel.o auth.o pty.o libwrap.o -lldap -lz -ldl -lutil -lnsl -lpthread -L/usr/local/sslfips112/lib -lssl -lcrypto This builds a stunnel that seems to run fine. During startup it says "stunnel is in FIPS mode." But if I run "ldd stunnel" it shows it needs /lib/libssl.so.6. While stunnel is running lsof shows it has that library open also. Why does my FIPS stunnel build still use the 0.9.8b shared library? Shouldn't all of the ssl dependencies been handled by the static FIPS openssl library during linking? The same issue exists for libcrypt.
