Crash if override_hostname Contains Certain Numeric Values

[jbuchbinder]

Are you also defining override_ip? If not, try defining override_ip to be the IP address of the spoofed name.

[vvuksan]

Nathan,

perhaps you can give me the actual names on the IRC channels. I should be able to replicate this.

[smith]

@jbuchbinder override_ip is defined. Here's the globals section:

globals {

  setuid = yes

  max_udp_msg_len = 1472

@vvuksan I sent you the domain name through the email on your website.

[smith]

@vvuksan That email didn't go through. The domains it was failing on were web02.who.is and web03.who.is

[jbuchbinder]

We recently committed a change to use an APR method rather than the manual string concatenation we had been doing before, so that should fix this. Could someone confirm?

[smith]

I've got this installed on a server, and FYI when using the passenger module from gmond-python-modules it fails on startup with:

{'status': 'sudo /usr/bin/passenger-status', 'memory_stats': 'sudo /usr/bin/passenger-memory-stats', 'metrix_prefix': 'passenger'}
apr_pollset_create failed: Invalid argument

That could be a bug in the python module, so I disabled it, and then I get:

apr_pollset_create failed: Invalid argument  

after loading the python module. This could be a problem with some module or configuration (I ran it with sudo /usr/local/sbin/gmond -d 2 --conf=/etc/ganglia/gmond.conf and installed the new version with --prefix=/usr/local.

I'll let you know if I can try it on a non-production machine with no extra modules. Let me know if there is anything else I can do to help you confirm.

[jbuchbinder]

Are you sure you have valid UDP and/or TCP listeners defined on that instance?

Thanks for that. I set set it to deaf. I'm running the commit for #49 shown above and it seems to fix the problem! Thanks
