[stunnel-users] Stunnel-4.10 and Stunnel-4.11 in HPUX-11.23 IPF gives coredump

Mon Jul 11 07:54:44 CEST 2005

Hello All,

I'm using HP-UX11.23 IPF. I have built Stunnel-4.11 with OpenSSL - 0.9.7e. I could build it successfully but I'm failed in connecting with telnet. 
After a while connecting to the telnet the client gets coredump and kills the process. So the connection is no more established. 

Note: I had the same problem in Stunnel-4.10 also but not before that. I could very well compile and use Stunnel-4.09.

My configuration file for client is:

cert = /opt/iexpress/stunnel/etc/stunnel/stunnel.pem
chroot = /opt/iexpress/stunnel/var/stunnel
pid =
setuid = root
setgid = root
CAfile = /opt/iexpress/stunnel/etc/stunnel/stunnel.pem
debug = 7
client = yes
foreground = yes
verify = 3
[test1]
accept = 8080
connect = 9090

For server:

cert = /opt/iexpress/stunnel/etc/stunnel/stunnel.pem
chroot = /opt/iexpress/stunnel/var/stunnel
pid =
setuid = root
setgid = root
CAfile = /opt/iexpress/stunnel/etc/stunnel/stunnel.pem
debug = 6
client = no
foreground = yes
verify = 1
[test1]
accept = 9090
connect = 23

The client log shows as follows:
