Chris McCauley's questions

I'm getting hundreds of entries in my access log with invalid requests like this ...

217.23.114.224|-|15/Dec/2010:08:17:19 +0000|-|-|-|400|0|-|-
217.23.114.224|-|15/Dec/2010:08:17:19 +0000|-|-|-|400|0|-|-

217.23.114.224|-|15/Dec/2010:08:17:20 +0000|-|-|-|400|0|-|-

My log file format is

'$remote_addr|$cookie__ourcookie|$time_local|$request|$content_length|$content_type|$status|$body_bytes_sent|$upstream_addr|$upstream_response_time';

The IP address varies and some of them are valid user IP addresses (not sure about the others). They often appear in the middle of a valid set of requests and then stop.

Anyone got an idea why I'd be getting floods of seemingly invalid requests coming in?

I don't think this can be explained just by saying that it's a hack attempt (though some of it could be) - is there any additional debug setting for NGINX?

Thanks

I have all of my upstart config files under version control. My ideal way to use upstart is to create soft links from my version control repository (mercurial - not that it matters) into /etc/init but upstart fails to see the jobs. Everything is fine if I copy the files from the repository directory to /etc/init.

Anyone know why upstart fails to handle symbolic or even hard links?

Thanks

For example can I set a limit on VIRT or RES and have upstart restart the server?

Thanks

Does anyone have any information on the prerequisites for sending HTTPS requests from SAP? I'm able to send HTTP Posts ok but I can't get a request to be sent over HTTPS. This is from ABAP

I guess the core of the issue is what needs to be done to tell SAP to use a HTTPS connection not the standard HTTP.

Thanks

I have three virtual linux servers running on Slicehost.

Two of them are running 2.6.24-23-xen one is running 2.6.18-xen. All three servers are running almost identical software but the behaviour of top is different between the 2.6.24 and 2.6.18 servers.

On the one running 2.6.18, the set of processes running (ordered by CPU activity) is pretty constant when no users are connected. The other two show constant changes in activity. In particular Ruby based services (mongrel_rails, merb and event-machine) are constantly jumping up and back down the list.

All servers are running ruby 1.8.7 (2008-08-11 patchlevel 72).

Any ideas why there is such a difference in behaviour?

Can anyone provide some insight on how to install a later nginx than the 0.6.32 in macports? On Linux I use 0.7.55 so would like to have the same on the Mac.

Follow-up : I realised that I could also build it from source like I do for Linux so that works for me.
