Package: shellinabox
Version: 2.20+b1
On a fresh Debian Stretch install I cannot get shellinabox to respond, seems
the web server side of it isn’t responding or providing a pool of connections.
I reused a working configuration from Debian Jessie with no luck. See
configuration details below. When attempting to access shellinabox over the
port set I end up getting no output from shellinabox (also tried on default
port with same results). I am using a proxy pass through apache, and the proxy
appears to be working fine. I’ve included that config below for reproduction
sake. With that said even accessing this on the box over localhost:4444 I still
have the same issue, so presumably the proxy pass has no effect on this,
especially since it was working on prior apache2 versions. Please let me know
what other output/logs you might need to resolve this, I’ll gladly help out,
thanks!

# SHELLINABOX_GROUP=shellinabox
# Any optional arguments (e.g. extra service definitions). Make sure
