Server :: Understanding Server URL Structures?
Oct 27, 2010
I guess I am trying to understand how webmaster's configure their servers on the Internet. I see servers that have the following:[URL]hat the webmaster above for 'mydomain.tld' has three separate unique servers for each hostname (mail, wiki, and www) above. Is it possible to get all the hostnames or aliases above running from one single piece of hardware? If so, how does that work? Obviously my single server will only have one unique hostname.

I'm trying to set up an Ubuntu server using 10.04 (64-bit), and running into problems after a couple of reconfigurations. Here's the full story:I initially built the server on a 400+GB RAID5 array, putting everything but swap in one partition. Unfortunately, I needed to repartition, putting / in the first primary partition, swap in the second partition, /var/log in the third primary partition and /home in the remaining space on the fourth primary partition.
However, at this step, I ran into some problems with UUIDs in /etc/fstab and Grub2 (I've used Linux for about 9 years, but I'm new to Ubuntu, and I haven't used UUIDs or Grub2 on Gentoo, yet). Consequently, I made the (probably not smart) decision to move back to the /dev/sdX notation I am familiar with.The problem with that is that now I need even more space on /home, so I've added a Dell Powervault and a Dell PERC5/e SATA card to my server. Now, Grub2 tries to boot from the new RAID array on the Powervault instead of the internal RAID array, so I am trying to move back to the UUID notation so that I don't have worry about /dev/sda being the internal array sometimes and the external array at other times.I don't mind being RTFM'd, but I'm having trouble finding pointers to the documentation explaining Grub2 configuration and the UUID notation. Does anyone have pointers to some readable, concise documentation on configuring this in Ubuntu?

I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.
I have installed Ubuntu 9.10 server x64 and have got apache running.
I am looking for the simplest more robust solution for smtp, pop3 and imap. I have only ever used qmail before and found it a pain to configure and its getting old so I though I should probably try something new. I have not much experience with running pop3 or imap on linux so would love a suggestion on that.

I hace some code C/C++ STL, which i need to use for android, using SDK-NDK-JNI.my problem is that i need to pass some STL structures across JNI, I can't pack/unpack data into basic types or arrays of basic types, doing my own simple streaming between the two layers.My application need to pass a pointer to a STL structure which is updated by eachuser interaction wonder if it is possible using NDK-JNI ?Other option is "native activity" but it also needs JNI in some way ... and passing the STL structures wille a requirement, yet.I only can package data into an own streaming if there is a second (concurrent) application running (implementing the STLfunctionality). Is it possible ?

I'm trying to do some kenel debugging (at runtime). For very basic debugging, I've inserted some printk() statements in my customized kernel source. Now I would like to do a full-dump of some data structures (struct sk_buff, ...) in different functions (e.g. netif_rx(), ip_rcv(), __udp4_lib_rcv(), ...), and what kind of locks are required to prevent "overlapping" of dumped data)?

I just ran the update manager and am now unable to access any of my files. Additionally I can not run the software center or run apt-get from the terminal. Luckily my web browsers and email client are still working.
I first ran the update a few days ago, but for some reason, about 30 or so packages wouldn't download, so update manager installed all but those ~30 packages. Afterwards everything seemed fine, except the clock was broken on my desktop, which corrected itself after two reboots.
Since that time the only major change I've made to the system is to rollback my version of gcc to 4.3.0 from 4.4.3. This was done in hopes that the older version of gcc would read a header file in some software I need to get installed (apparently ubuntu doesn't like locale.h). However, doing so did help.
Today when I got into work I thought I would see if I couldn't finish the update before trying some different versions of gcc, so I ran the update manager again. This time it downloaded the remaining ~30 packages and installed them, no problem. It wasn't until I ran apt-get that I noticed that all the icons on my desktop had disappeared.
below is the error I get from running apt-get
Code:
chris@chris-laptop:~$ sudo apt-get install build-essential
apt-get: /usr/local/lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by apt-get)
apt-get: /usr/local/lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by /usr/lib/libapt-pkg-libc6.10-6.so.4.8)

Right now i have a HP DL 180 Server with 130 Gb Hard Disk & 8 Gb ram after Raiding0+1. i want to configure Domain Controller Server for my office for 200 to 300 Users. what should the partition size must be mentioned in my 130 Gb Hard Disk, is that going to be Sufficient for ME ?
i am bit confused about /Usr /Var /Boot partitions, as i need to manage perfectly in 130 GB
if i go with 4 Gb swap and remaining for " / " is that will be fine ? should i need to specify partition sizes separately for / tmp /var / usr ..

The site loads slow and clicking a link almost freezes the page for a second. Also, the page loads could be much faster. We've been running mysqltuner and have pretty much optimized all slow queries. Is there anything we can do to fine tune the server for faster and more responsive?

I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

I have got a running mail server on CentOS5.4 Final using Zimbra free edition. . Assume that domain is organization.com.local And it is running fine with users created and bugzilla running on the same machine can send mails using this server. But it can obviously send messages to the internal users. There is this option to configure it to use external mail server to send mails outside the network but my external smtp server needs an authentication.Is it possible to configure it this way to use my external server to send mails from internal domain to say gmail?
