It's probably set to use DHCP, so you'll need to switch it over to whatever static IP you wanted to use.

I've put Linux boxes between Exchange and the outside world running postfix+SpamAssassin+Amavisd-new plenty of times. It helps cut out a lot of junk mail. However assuming you have a new(ish) version of Exchange doesn't it do a lot of antispam out of the box?

What happens when you troubleshoot with nslookup?

I use a PXELinux boot menu. PXELINUX - Syslinux Wiki One of the options being Clonezilla.

I do hope the Sky at Night can carry on without him.

I don't currently have any invites, but when I get some I'll let you know.

Ugh, that's terrible engineering if it's true. You should never design things to fail 'on' you should ensure that if anything goes wrong it all turns off and comes to a complete stop in as carefully a control manner as possible under the circumstances.

Is DNS scavenging enabled? Are dynamic DNS updates working?

As far as I can discern from the bugzilla the scrolling issue was fixed around two and a half years ago in v6.0.5 or shortly thereafter. Bug 45905 – ipad support for mobile lite client

If you think it is SELinux you can temporally put it into permissive mode to check.

Well the buttons on the Polycoms all work however I also give them iSyphony. Operator Panel for Asterisk - iSymphony

For general traffic If you have managed switches you can query them via SNMP and ask for their traffic counters. As long as you know what uses which switch port (and you should!) then it'd be fairly obvious (I have a Linux server running Cacti doing this here). Short of that, as above you need to mirror the port and monitor the traffic flows that way. If you main switch doesn't support mirroring then another option is have a machine setup as a layer 3 bridge and run some monitoring software on that (I've done this in the past with ntop on Linux). If it's simply web traffic that's the issue (usually the only internet traffic a school network produces in any quantity due to how locked down LEA networks are) then you should be able to work out the usage from your web proxy logging.

Make sure the new machine has a GigE nic (I'd be amazed if it doesn't) and you have a GigE port for it somewhere near your network core.

Personally I use Ubuntu LTS on my servers. As you say it's perfectly possible to connect up to your AD domain with samba for user authentication. If you struggle setting this up (quite a lot of people do on the first few attempts), there's plenty of help here to get you through it. As for your choice of hardware, it is more than adequate for what you want. As you're using it as a file server then processing power isn't a big deal. It's the amount of ram that is important. More ram means more file caching.

If the cache_dir is commented out then it's not using the disk for caching. If you want to check if your disks are ok the best thing to use is to install (assuming these are IDE/SATA disks?) smartmontools (that's the package name in Debian based distros anyway) and run: smartctl -a /dev/sda Obviously change the device path for your actual disk drive.

It will log to the syslog about bad sectors/etc and also email you if so configured.

Well if you're not interested in editing config files then the only Admin interfaces that works properly are the FreePBX and Elastix ones.

*shrug* most of my asterisk work is command line? Or are you farming out admin access to some users?

That's the 'default' location for squids cache. If it's been put somewhere else by your distros install then you will have to look at the squid config to find out where. Check what the 'cache_dir' parameter says in 'squid.conf' squid : cache_dir configuration directive It also occurs to me there may be an underlying hardware issue causing all of this. Are your hard drives ok?

Something along the lines of: service squid stop rm -fr /var/lib/squid/cache/* squid -r service squid start Basic idea is to stop squid, delete the entire cache, tell squid to recreate it's cache then start squid up again.

I think around 1.7?

It depends if you use different ports for transparent vs non-transparent (which you should, otherwise you get those netfilter errors).

I take it squid is running transparently from the NetFilter errors? What happens if you directly proxy rather than run as an intercept?

Have you ruled out issues with your internet connectivity?
