On the near future I will have a WordPress blog, public and visible to anyone, that has a members area. This members area accesses some private data on a special database with financial data, so this kind of info should only be viewable to customers of the site. The private site will be running inside a VPN on a business LAN and a little server, and I wonder if hosting that private part together with [...]

From Wikipedia: In the Internet addressing architecture, a private network is a network that uses private IP address space, following the standards set by RFC 1918 and RFC 4193. These addresses are commonly used for home, office, and enterprise local area networks (LANs), when globally routable addresses are not mandatory, or are not available for the intended network applications. I wonder if private network and LAN are the same concept? If not, what relations do [...]

What are some good alternatives to the virtual private server company sliceshost? I would like a few alternates providers. Linode are who I am with. They have very good pricing, good performance (google search “slicehost vs linode” for example) and a very active support community in the forums and IRC if you need help. Highly recommended!

It is suggested in this question that it’s not a good idea to expose a private IP address via a public DNS entry. My question is then what’s an elegant and easily maintainable way to allow multiple users on diverse platforms (Mac/Windows) connecting to a VPN to use a standard centralized address naming schema without asking them all to hack their hosts files (which really isn’t an option in my case)? Clarification: I’ve set up [...]

I need to set up an IM system for a network that won’t be connected to the internet – probably just a number of laptops connected via wireless. There will be a central server. What options do I have for clients and server software? Open source or free would be preferred. Thanks. XMPP (Jabber) servers work just fine without an internet connection. I use ejabberd and it works quite well, but there are a number [...]

I tend to copy some useful programs to every server I login to. I have loads of configuration files, a statically compiled zsh (in case I need a new version), vim, python, version control binary, etc. I have a script that just checks them out, links all binaries to ~/bin if they’re newer than the system-wide versions, and does all the needed setup – I’ve got the setup I need on any kind of host/distro. [...]

I have two physical hosts running Xen 3.2, sharing storage via iSCSI. On these two hosts are a number of domUs and I’d like to network them in multiple private networks so they can only contact other domUs on their private network. My understanding of the xen documentation suggests it’s possible to do this within one dom0 (ie create virtual networks between domUs), but I’ve found nothing explaining how this can be implemented across multiple [...]

I purchased a .org domain from network solutions and I was thinking about using it for a intranet website running IIS6. I don’t want this to be a public facing website. How would I set this up? By my understanding, you didn’t even need to purchase it. If the site is intranet, you could just set up a DNS server to point LAN computers from any domain to any server. On my LAN, I can [...]

Have successfully connected to my ASA via VPN client. Setup: ASA >> Switch >> 2 CentOS Linux Servers When I open a local terminal (OSX), I can ping inside interface on (192.168.0.1) but not inside servers listening on 192.168.0.2~254 Inside servers can ping each other as well as 192.168.0.1 Seems that VPN ping requests to server-on-inside-IP are getting sent back out on Linux box’s public interface (gateway is set on public, not private) Not by [...]
