"Router/gateway/firewall in a virtual infrastructure" posted by ~Ray
Posted on 2008-01-02 03:11:40

I'm looking at possible candidates to act as a router/gateway/firewall in my planned virtual infrastructure. I will have a physical LAN on one side the internet on the other and internally a sort of DMZ for my server VMs. (See attached illustration if you don't get it. )I have looked at the following so far:m0n0wallpfSenseSmoothWall ExpressSince I have been having issues with communicate performance in FreeBSD 6.2 I'm somewhat dubious towards m0n0wall and pfSense but I evaluate their base is a FreeBSD pre-6.2 so it might be ok using the vmxnet device for good performance. But my favorite so far has been SmoothWall however I had some trouble with its DNS server/proxy. What do you use or advise and what makes it good?/Zxinn

You can try to use it to let it do all that is possiblein AWStats setup however following the go by step manual setupdocumentation (docs/index html) is often a better idea. Above all if:- You are not an administrator user,- You be to analyze downloaded log files without web server,- You be to care for send or ftp log files instead of web log files,- You need to analyze load balanced servers log files,- You want to ‘understand’ all possible ways to use AWStats…construe the AWStats documentation (docs/list html). —–> Running OS detected: Linux. BSD or UnixWarning: AWStats standard directory on Linux OS is ‘/usr/local/awstats’.

Do you be to act setup from this NON standard directory [yN] ? y Enter full config file path of your Web server.

You can run this tool later to build asmuch config/compose files as you want.

"VMWare" posted by ~Ray
Posted on 2007-12-09 14:44:06

I undergo been playing w/ VMWare Fusion (for Mac OS X) and VMWare Server (for Windows) over the weekend and now undergo a bring together of FreeBSD virtual servers running on my iMac and my X40 (both with 1.5GB RAM). This provides a server environment virtually identical to our production server facility for use as a self-contained development server on-the-go change surface where there is no network. Performance of the virtual server on the iMac (dual core) is very good. The X40 is a much slower machine so setting the virtual server up to a useful state takes much longer althou once this is done the whole thing is very usable. VMWare Fusion is USD80. VMWare Server is remove (as in beer). I’ll compete some more and affirm that the virtual machines created under one environment is compatible with the other. Tags: · · There are no comments yet...

"CARP pfsync and gmirror for firewall failover and raid1 mirror ..." posted by ~Ray
Posted on 2007-10-03 19:16:03

Jephe Wu - obtain Firewall is very important for company network it protects all valuable resources on the internal LAN. To forbid the single inform of failure it's always good practice to apply firewall fail-over. FreeBSD is a good choice to act as a firewall because it's popular secure and give packet separate(PF) which is ported from OpenBSD as come up as CARP pfsync. Software raid drive - gmirror in FreeBSD is extremely easy to assemble. Environment1. 2 HP netserver lp1000r (running Freebsd 6.2)2 each lp1000r server has 2 built-in network ports one connects to Internet the another connects to internal network3 each lp1000r3 web servers behind the firewalls using internal IP addresses (running CentOS 4)Objective1 when firewall1 is drink firewall2 ordain be taking over. This should be transparent to the end web user.2 since each hp netserver lp1000r has 2 idential hard disks(18G) we need to create it as raid-1 mirroring. In case any one of hard plough dies the firewall is still able to work.3. 2 web servers are also DNS server. SMTP server and NTP client which means we need to assemble the relevant PF rules on each firewall.
