Hi All,

I have thttpd server cross-compiled for my ARM based embedded board. Now I want to add the support for https services on my board, so I think of using stunnel with openssl. I have already download source code of openssl and cross compiled it, for linux-arm. I have downloaded stunnel-4.21 and followed the steps as mentioned below.

1. create stunnel.pem file inside /etc/ssl/certs/stunnel.pem 2. create stunnel.conf file inside /etc/stunnel/stunnel.conf with following parameters.

cert = /etc/ssl/certs/stunnel.pem key = /etc/ssl/certs/stunnel.pem chroot = /var/run/stunnel setuid = stunnel4 setgid = stunnel4 debug = 7 pid = /stunnel.pid setuid = stunnel setgid = stunnel socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 compression = rle output = /var/log/stunnel4/stunnel.log client = no [https] accept = 10.103.2.104:443 connect = 127.0.0.1:8080 TIMEOUTclose = 0

2. ./configure --prefix=/home/stunnel --host=arm-linux --enable-shared --with-ssl=/home 3. changed CC, RANLIB and STRIP environment variables for cross compilation in Makefile. 4. make 5. sudo make install

The cross-compiled binary stunnel is installed. When I run the binary on board, it does not show any error. Following debug messages are seen on screen.

1969.12.31 21:19:54 LOG6[1154:1073842296]: Compression enabled using rle method 1969.12.31 21:19:54 LOG7[1154:1073842296]: RAND_status claims sufficient entropG 1969.12.31 21:19:54 LOG7[1154:1073842296]: PRNG seeded successfully 1969.12.31 21:19:54 LOG7[1154:1073842296]: Certificate: /etc/ssl/certs/stunnel.m 1969.12.31 21:19:54 LOG7[1154:1073842296]: Certificate loaded 1969.12.31 21:19:54 LOG7[1154:1073842296]: Key file: /etc/ssl/certs/stunnel.pem 1969.12.31 21:19:54 LOG7[1154:1073842296]: Private key loaded 1969.12.31 21:19:54 LOG7[1154:1073842296]: SSL context initialized for service s

But, If I try to request https service from web browser (Firefox) ie, https://server_ip it gives me error. Meaning https server is not started correctly, still something is missing.

Please guide me if you have any clues. Any help would be highly appreciated.

Thanks, Krinali Shah
