I'm now using the latest version of ldirectord. There was no change in the
bug. I have a global variable that changes the output of the web server
(http & https). Ldirectord seems to work for port 80, but not for port 443.
I have multiple external IPs natted and looking at the real servers on both
port 80 & 443.
It's looking for "Connected successfully". When turned off it no longer
appears; however, the debug code seems to allow the output, even though
it's not there (external IPs changed to x.x.x.n):
DEBUG2: Checking connect: real
server=connect:tcp:10.0.3.11:443:::1:masq:\/index\.html:Connected\
successfully (virtual=tcp:x.x.x.54:443)
DEBUG3: Connected to 10.0.3.11 (port 443)
DEBUG2: Enabled real
server=connect:tcp:10.0.3.11:443:::1:masq:\/index\.html:Connected\
successfully (virtual=tcp:x.x.x.54:443)
DEBUG3: Activated service 10.0.3.11:443
This is output when enabled, meaning changing the output of the webserver
to show "Connected Successfully", not turning on the webserver:

About the only thing I can think of it is caching the good output. As a
work-around maybe I need to check on port 80 instead of port 443? I ran
this test:
(1) Removed the receive string: http:80 dropped out (https should have
dropped out too)
(2) Turned off the web server: https:443 dropped out.
(3) Turned on the web server: https:443 popped in (didn't respect the
receive string)
(4) Enabled the receive string: http:80 popped in.
This tells me that either (1) https is cached for a very long time or (2)
ldirectord it doesn't work properly.
Here's my conf for this example:
virtual=x.x.x.54:443
fallback=127.0.0.1:443
real=10.0.3.10:443 masq 1
real=10.0.3.11:443 masq 1
real=10.0.3.18:443 masq 1
service=https
request="index.html"
receive="Connected successfully"
scheduler=rr
#persistent=600
protocol=tcp
checktype=connect
Is this correct?
Thanks,
Brent
