Hi Gerald,

I assume you got stunnel from the oss4aix.org site.

We don't use the freeware openssl, but instead the IBM one:

[root@duist:/data/O01] lslpp -l | grep openssl openssl.base 1.0.2.1801 COMMITTED Open Secure Socket Layer openssl.license 1.0.2.1801 COMMITTED Open Secure Socket License openssl.man.en_US 1.0.2.1801 COMMITTED Open Secure Socket Layer openssl.base 1.0.2.1801 COMMITTED Open Secure Socket Layer

I installed stunnel-5.29 on one of our lpars which I forced with -nodeps: rpm -Uhv --nodeps stunnel-5.29-1.aix5.2.ppc.rpm

It picked up the IBM libs, but had the same problem...

I then downloaded and installed stunnel-5.49 from oss4aix.org and installed that version which worked fine..

I expect that if you upgrade your freeware openssl to at least 1,0,2r and upgrade stunnel to 5.49 your problem should be solved.

Met vriendelijke groet,

Hello all,

I'm new to the mailing list. I'm trying to run stunnel-5.29-1.ppc, and I'm having issues. I'd appreciate your help (or point me to the solution in the archives).
