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:

It will be helpful if anyone of you guide me in this. Thanx In Advance.

It looks just like the problem with uc_stack.ss_sp on Sparc/Solaris 9 and earlier. I'm sure I could fix it, but I don't have any HP-UX machine to test it. Maybe someone could provide me with an account?
As a workaround (not the solution) you can use: ./configure --with-threads=pthread

Hello Mike,
I've tried --with-threads=pthread already. I got the following error during gmake.
gcc -g -O2 -Wall -Wshadow -Wcast-align -Wpointer-arith -I/opt/openssl/include -o stunnel client.o log.o options.o protocol.o network.o resolver.o ssl.o sthreads.o stunnel.o pty.o -lnsl -ldld -ldl -L/opt/openssl/lib -lssl -lcrypto -lwrap ld: Unsatisfied symbol "pthread_create" in file sthreads.o ld: Unsatisfied symbol "pthread_attr_init" in file sthreads.o 2 errors. collect2: ld returned 1 exit status gmake[1]: *** [stunnel] Error 1 gmake[1]: Leaving directory `/home/punitha/stunnel-4.11/src' gmake: *** [all-recursive] Error 1 #
I've also tried with --with-threads=fork. Here I can compile successfully. During the connection establishment I get some problem. When I close the first connection, both the client and server processes gets down with the following message.
sendsig: useracc failed. 0x200000007f7fd200 0x00000000005000
Pid 573 was killed due to failure in writing the signal context - possible stack overflow. Illegal instruction
When I close the second and other connections I just get the log messages on the screen. I've attached the sample log messages for both client and server.
Regards, Punitha, V.

Hello Mike,
I can go with --with-threads=pthread option.
Thank you, Punitha, V.
