• Using my System as the server- need advice

  - by Ashwin

  We are deploying my web application in my system in jboss. And I am planning to use my system as the server as well. There are no html pages or jsp pages deployed. The client requests for resources and the server provides the resources in the form of objects. We are also using databases(Postgresql-15 tables) as the database server(this will also reside in my machine). My system configuration is Windows Vista, 2.3 GHZ, 4GB Ram, 32 bit. There can be many requests coming in at the same time. So is this configuration enough? Should we go with a different Operating System like Windows Server? I have never used Windows Server OS. How will it be different from other windows operating systems? Or if you feel please some other OS will be good in this situation, please suggest.

• What is windows 8 core?

  - by Journeyman Geek

  I've found some references, when looking for information on WAIK installs of windows 8 of a varient called windows 8 core, that can be installed off the professional edition disk. There's also a mention of it on winsupersite that says The cheapest, called MSDN Operating Systems, costs $699 a year ($499 renewal), and of course includes Windows 8 (Core), Windows 8 Pro, and Windows 8 Enterprise. You get five licenses each for Windows 8 Core and Pro, and one Multiple Activation Key (MAK) for Windows 8 Enterprise. What is windows 8 core? Is it the new 'home' edition or something else? What differentiates it from the pro and enterprise editions?

• How to setup a fast VPN server

  - by Saif Bechan

  I am trying to set up a VPN that has a fast download speed. The server I have is a linux server and from there I can download 2 megabytes a second. At home I can also download with 2 megabytes a second. All the downloads I do are from the same source, no different server. Now I have set up a VPN connection between my home and the server, and now I am only downloading 64 kilobytes a second! The connection I have created is a PPTP server on a debian machine. Now my question is if it is possible to optimize this connection. Should I maybe switch to OpenVPN, or change operating systems? Or are there some kind of settings to tweak to make the connection optimal. PS. The server I am running is on a XEN node. I have done the proper ip forwarding.

• Co-worker told me ubuntu server LTS is not built for production env

  - by Sandro Dzneladze

  I was confronted with a very vague statement today, but unfortunately I had no clue how to respond or analyse this. Co-worker told me ubuntu server LTS is not built for production env. What is there that makes it not built for production environment? (obviously no answer followed, so this is my question to you...) is it ...packages? ...ease of use? ...supported systems? ...stability? ...support? ...popularity?

• Why is ext3 so slow to delete large files?

  - by Janis Peisenieks

  I have a server, which makes an incremental backup of a system every night. Now on saturdays, there is a full backup. But after the full backup has finished, a script kicks in, that deletes the incrementals. Now, the script sometimes breaks, and it is because the incrementals are each about 10GB files, and sometimes takes too long for the script. Now could someone explain to me, or point me in the direction of a resource, that explains why ext3 is so slow to delete files, when compared to, lets say, NTFS? I know theses are 2 completely different file systems, but I'm really interested why is there such a big difference in deletion?

• Remote connection to dynamic public ip & private ip addresses

  - by user51737

  Many times I connected to windows computer which has static public ip address via remote desktop over wan links. I'm wondering how could I connect to the remote computer that has dynamic public ip address & private ip addresses assigned. I've 2 systems at home: xp system-------connected to internet(dynamic public ip) & allowed other users to connected to the internet on the interface. windows vista system--------enabled dhcp on the interface to access internet from xp. How could I remotely connect from my office to the 'vista system'?. If I've a router/modem at my home it may be possible to allow the ports for the system but I don't. Any tips?

• Virtual Windows Servers and Pagefile location [closed]

  - by Luke Puplett

  Considering that Windows makes heavy use of the pagefile even with huge amounts of RAM available, is it not best to have this pagefile on the fastest disk possible as close to the virtual systems as possible? I'm thinking, RAM disk. Where I work, storage for VMs is out on a NAS/SAN. I'm worried that so much memory access is having to go across the network! As a side, I think its about time MS got rid of paging and told us to buy more DIMMS. UPDATE So this question has been downvoted??! Accessing a local spindle is C40,000 times slower than a DIMM, so going over the network will be even slower for hard faults. I don't know why I got the downvote, I'm certain that this is an issue unless there's some other mechanism in ESX/HyperV that manages this.

• How do I capture the output of a tty while still allowing sent characters to reach the correct desti

  - by Zak

  I currently have some systems that multiple people have access to for administration purposes. We've modified the history log so that we capture 2k lines of history per user to help aid in who has done what on the system. However, we would additionally like to capture all keyboard input when we (the administrators) log in, and log it to a file so we can see what changes were made to files once people go into vi to edit them. It will also aid us in documenting when we are going through a compile of software and the like. How can I do this? CentOS 5.4 if it makes a difference.

• Suggestions for someone wanting to become a Laptop Reseller

  - by Josh B.

  First of all, to give you a little background... I have had my Microsoft A+ for several years now. I used to run a small business repairing Xbox 360 consoles and I am currently a Network Engineer for a company in Ohio. I definitely know my way around a computer. I miss running a small business on the side and I'd like to get something going again. There is a really high demand in my area for Laptops and I was thinking about starting a small Laptop store out of my house. What is the best way to do this? I was assuming that the best way would be to buy barebones systems and build them yourself. If this is the best method, I would be very interested in any resources to get parts and such. Apparently Laptop parts aren't the easiest thing to come by (especially at a good price). Does anyone have any suggestions about how to get something like this going?

• options for deploying application

  - by terence

  I've created a simple web application, a self-contained tool with a user system. I host it publicly for everyone to use, but I've gotten some requests to allow companies to host the entire application privately on their internal systems. I have no idea what I'm doing - I have no experience with deployment or server stuff. I'm just some person who learned enough JS and PHP to make a tool for my own needs. The application runs with Apache, MySQL, and PHP. What's the best way to package my application to let others run it privately? I'm assuming there's better options than just sending them all the source code. I'd like to find a solution that is: Does not require support to set up (I'm just a single developer without much free time) Easy to configure Easy to update Does there exist some one-size-fits all thing that I can give to someone, they can install it, and bam, now when they go to http://myapplication/ on their intranet, it works? Thanks for your help.

• search nfs network volume from mac client

  - by user1440190

  Asked: how does a Mac OSX SL or Lion user search the cluster for a particular file (foo.txt) "From the cluster, you would need to run some form of recursive lookup for the file desired. As an example, using 'find'. RAM-1# find /ifs |grep test.txt /ifs/Elements/avid2test.txt /ifs/Elements/test.txt I would suggest contacting Apple support regarding their recommendation for searching for files on remote file systems from the Mac client itself" OK that's great, but I don't want users using CLI !!! Anyone know a good method (non-CLI)? Spotlight is not an option. BTW cluster is roughly 80TB

• Issue with broken disk on Solaris with raidctl - how to proceed

  - by weismat

  I have a SunFire T2000 server which has 2 mirrored disks pairs. The server required an exchange of the system battery. After swaping the battery first no disks were found. After booting from CD we managed to find the disks, but now one disk is broken and the raidctl reports a failed synchronisation. The boot process stops now when trying to mount the file systems. The power light of the broken drive is not even blinking. What is the best way to proceed now ? Fortunately I could live with loosing the data on the drive as it is backed up, but I would like to keep the rest of the data as it contains /etc and get the server booting again.

• Combine OS partion with data partition on NAS4Free/FreeNAS

  - by Pak

  I recently built a NAS4Free (formerly FreeNAS) machine using a 256MB (yes, MB) USB drive for the OS. When I did the original install, I had the bright idea of making the OS partition just big enough for the OS and a then creating a second partition using the remainder of the drive to store stuff pertaining to the OS. I never really found a use for the data partition and I ended up running out of space on the OS partition, so now I'd like to combine the partitions into a single partition. Is this something that is possible to do while everything is up and running? If it comes down to it, I can take down the machine and do a fresh install of the OS using the entire space of the USB drive, but I'd like to use this as an opportunity to better familiarize myself with FreeBSD/UNIX type systems. If this is possible, will it interfere with the NAS4Free things? The data partition shows up in the web interface under the disks section. If I end up manually changing the partitions, I'd be concerned with NAS4Free getting confused by the missing partition.

• Squid3 not working. Access denied

  - by Nitish

  I installed SQUID3 on a Linux machine with two ethernet interfaces (eth0 and eth1). I used the default settings in the squid.conf file and uncommented the two lines acl localnet src 192.168.0.0/16 and http_access allow localnet. eth0 is connected to a router, which provides Internet access. It is assigned an IP 192.168.1.2 by the router. I manually configured eth1 to have an IP address 192.168.5.1. It is connected to a switch. Systems having IP addresses 192.168.5.x are connected to this switch. I ran these two commands for NAT: iptables -t nat -A PREROUTING -i eth1 -p tcp -m tcp --dport 80 -j DNAT --to-destination 192.168.5.1:3128 iptables -t nat -A PREROUTING -i eth0 -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 3128 But when I try to access internet from a system having IP 192.168.5.2 through the proxy I get an error that says "Access denied". What is wrong with my configuration?

• IIS - Script for repeated hacks on a website

  - by dodegaard

  I currently have a site that is armored by ELMAH as its reporting mechanism. Each time someone hits a URL that is incorrect it notifies me or logs to the system. This is annoying for someone fat-fingering the URL with a misspelling but great when a hacker is trying to crack a site of mine. Has anyone ever written a script for IIS 7 on Win 2K8 that blocks an IP based on repeated attempts to hit a website? I've looked at Snort and other IDS systems but if I could get a script that could be linked to my ELMAH system it might be the perfect thing. PowerScript, etc. is what I was thinking. Hints and recommendations are wonderful and if you think a true intrusion detection system is recommended give me your ideas. Thanks in advance.

• Installing Color-Theme with GNU Emacs 23.2 on OS X Snow Leopard

  - by idclark

  Hi all, I've just started using emacs a week ago and I've been unsuccessful in installing color-theme using GNU Emacs 23.2 on OS X. With Ubuntu the whole process took maybe a few minutes with the package manager, but I'm completely at a loss with OS X, what the heck is a "tarball"? I don't have any experience compiling source code. I know Carbon Emacs comes with color-theme packaged, what would i lose by reverting to Emacs 22? I'd prefer staying with GNU Emacs 23 across both systems. Any input is greatly appreciated!!

• High frequency, kernel bypass vs tuning kernels?

  - by Keith

  I often hear tales about High Frequency shops using network cards which do kernel bypass. However, I also often hear about them using operating systems where they "tune" the kernel. If they are bypassing the kernel, do they need to tune the kernel? Is it a case of they do both because whilst the network packets will bypass the kernel due to the card, there is still all the other stuff going on which tuning the kernel would help? So in other words, they use both approaches, one is just to speed up network activity and the other makes the OS generally more responsive/faster? I ask because a friend of mine who works within this industry once said they don't really bother with kernel tuning anymore-because they use kernel bypass network cards? This didn't make too much sense as I thought you would always want a faster kernel for all the CPU-offloaded calculations.

• Using iTunes within Terminal Services 2008 R2 - Pitfalls etc

  - by Kristiaan

  I was hoping to get some further information on any possible Do's and Don't when it comes to installing, using and maintaining iTunes within a Termina Server environment. We have come across a situation in our company whereby some of our users who are using thin clients now need the ability to sync, update and manage their devices, previously they used either standard desktop systems or laptops so there was no issue with running iTunes. I have not found much information on the web about using iTunes within a Terminal Server Farm, Id like to find out if iTunes works within the environment, any known or common issues that occur due to running it like this.

• How can I get rsync to ignore missing files?

  - by Joe Casadonte

  I'm executing a command like the following to several different systems: $ rsync -a -v [email protected]:'/path/to/first/*.log path/to/second.txt' /dest/folder/0007/. Sometimes *.log does not exist, and that's OK, but rsync generates the following error: receiving file list ... rsync: link_stat "/path/to/first/*.log" failed: No such file or directory (2) done Is there any way to suppress that? The only way I can think of is to use include and exclude filters, which just seem a PITA to me. Thanks!

• Accessing VMware Player across the network

  - by Tiffany Walker

  My network: 192.168.2.2 (computer) 255.255.255.0 (mask) 192.168.2.254 (gateway) The VMplayer is: 192.168.233.129 (ip) 255.255.255.0 (mask) 192.168.233.255(bcast) It's obvious the player can't be access from other systems because of the wrong network settings. However, I am not sure as to how to change that. Obviously I have to edit the ifcg-eth0 but I know I also need to edit it on the host system to make it accessably. Is this done from inside VMware Player? Or do I need to edit the network devices? The host box is Windows. Inside VMware is Linux.
