• PC cannot see Clonezilla server when using PXE Boot

  - by r2b2

  Hi I have about 15 workstations, all have the same hardware specs so I figured clonezilla is perfect for cloning them. So I followed everything this guide says :cloning groups of school computers That guide above makes it all look easy but when I tried setting up Clonezilla Server Edition on my laptop (Kubuntu 10.10) and configured the master computer for PXE boot, the master computer could not see the Clonezilla server. It just shows 'DHCP...' which seems it trying to grab an IP address but to no avail. Please help. Thanks!

• SSL Certificate

  - by Dremarturg

  Hey, I have a mail-server running and I want to buy a SSL-Certificate as they are pretty cheap now. I use mail.domain.com as reverse-DNS, POP3 and SMTP clients use mail.domain.com (some use pop3.domain.com and smtp.domain.com) for sending and receiving e-mails. The SSL-Submission asks me for a domain - is it mail.domain.com or domain.com as I do not have a Wildcard-SSL? I just want to use it for Mail. Or is it possible to use it for both by using domain.com? (Apache and Postfix/Courier on the same server and IP)

• X58 RAID 10 - Am I forced to use Sata2?

  - by Avi

  I'm building a new dev computer. It will be running a few VMWare Worksation virtual machines. I was advised on Serverfault to use Raid10 for performance. Raid 10 uses 4 disks. I contacted my supplier who suggested a gigabyte X58A motherboard and 4 Western Digital Caviar black 6Gb/s disks. I have checked the spec for the X58A board, however, and it says: SATA 3Gb/s: RAID 0, RAID 1, RAID 5, and RAID 10 SATA 6Gb/s: RAID 0, and RAID 1. I'm losing half the bandwidth because I'm forced to use SATA2! What should I do?

• Windows Server Configuration Management Best Practices

  - by Anton Gogolev

  Chef/Pupper/Ansible are cool and all, but they are second-class citizens on Windows at best. We have a bunch of "snowflake" (one of a kind) machines (baremetal and virtual) that nobody really know what's going on with. What I want is to start establishing basic configuration management for said servers, starting from installing Windows, installing and enabling various Roles and Features, setting up Services, Shares, Users and deploying webapps. PowerShell DSC looks promising, but it's not yet here and appears to be over-engineered, Puppet and the like are again not first-class. There's a bunch of tooks and TLAs like Windows ADK, DISM, OCSetup, etc. and it seems to me that the "Configuration Management" story on Windows is not precisely rainbows and unicorns. What I want is a Puppet/Chef-like, lightweight tool (no System Center Configuration Management, please) which would allow us to "version-control our server infrastructure" and bring all the benefits of CM. So, where do I look for the tool that does this kind of thing?

• disable browser localization

  - by broiyan

  How do I get the websites that I visit to stop localizing the language probably according to my IP location? This is an website specific issue because, for example economist.com and superuser.com do not do it, but Google Checkout and craigslist.org are doing it. Is there a way to setup Ubuntu and Firefox so that English will always be used for all web pages displayed? Edit: Of course many webpages have a link to an English version, but sometimes they don't. For example I believe such links usually appear on the root resource but sometimes I see non-English languages on child resources where such links do not appear. Example: most Blogger.com blogs appear in English but when I go to the blogger's profile ("view my complete profile"), it appears in another language that matches my geographic location.

• Automatically reboot Windows8 if no internet activity [migrated]

  - by Patrick

  I have a media server located in a very inconvenient part of my house. Occasionally I will have to reset my router or it will reset itself. The issue is the PC loses connectivity for some reason, and I am forced to walk outside, around the house, into the basement, over a bunch of toys and weights and boxes, to push a button to reboot it. I would love to have it check itself every 5-10 minutes and auto reboot if it is unable to ping a given address/IP. Any ideas how to accomplish this?

• Server goes offline. What to look for?

  - by Jonathan Sampson

  I'm using a new virtual server through GoDaddy, and this morning I received a call from the powers that be informing me our website was offline. After confirming this, I requested a power cycle through our GoDaddy control panel, and within a minute or two the server was back online. I made the call, and reported the news that we're back up. Of course, a couple minutes later we're down again. I tried connecting through PuTTy, and it takes forever to prompt me for a username, and each successive prompt takes a long time to come up. I'm using CentOS. So my questions are: How can I determine the cause? What types of things can I do to prevent this in the future? One interesting, and perhaps relevant, observation is that yesterday our bandwidth consumption was about 20% greater than our top figures from the past month.

• USB MFP print server that works with Windows x64?

  - by hangy

  Right now, we are using the Longshine LCS-MFP101-2 to connect to our MFP device (printer/scanner combo) over LAN. However, the required driver (RMVUSB, Remote Virtual USB) cannot be installed on 64 bit Windows operating systems such as Windows XP x64 or Windows 7 x64. Since the distributor lists the product as "phased out", I do not expect any updated 64 bit drivers any time soon. :/ Because of that, I am searching for a relatively cheap SOHO MFP print server (1 USB port should be enough) which can be used with 32 bit and 64 bit versions of Windows. Do you have any ideas or recommendations? Thanks!

• Are there any benefits to using a Distributed vSwitch for iSCSI?

  - by dunxd

  I am designing our vSphere farm - we'll be migrating from ESX 3.5 to 4.1. I plan to set up a new farm using ESXi 4.1, and move the Virtual Machines on the 3.5 farm into it by shutdown, then import. In ESX 3.5 there is no distributed networking, so each host has a vSwitch connected to my SAN NICs, and a port group for the vmkernel. In vSphere (ESXi 4.1) I have the extra option to set up a distributed vSwitch and distributed port groups for vmkernel to access iSCSI storage. Is there any benefit to this, or should I stick to non-distributed networking for iSCSI.

• Cloud services can't be reached from complex customer infrastructure

  - by Nock

  We have several services running on a cloud, they all are hosted on Windows Server 2012 R2, have public IP address and specific port. Some of our customers can't reach them because for "some reason" the ports are cut between a firewall between them and us. (some customers are using a shared internet connection in a multi tenant office and they can't change firewall communication) Well, you get it, we don't have the possibility to make all the firewall "allowing" the communication. My customers all runs Windows 7 at least. What is the best counter solution in such case, using Microsoft (Windows Server) technologies? The best would be some kind of tunneling communication or VPN, but the customer should also be able to access his/her enterprise resources. Bby the way, today we using IPSec using Windows Firewall to secure the communication, is IPSec tunneling a solution for us? Otherwise, is there a service in Windows to enable some kind of VPN between a client and a server but only for a given set of servers?

• Ubuntu Linux: Process swap memory and memory usage

  - by David Halter

  My Ubuntu eats more memory than the task manager is showing: sudo ps -e --format rss | awk 'BEGIN{c=0} {c+=$1} END{print c/1024}' 1043.84 free -m total used free shared buffers cached Mem: 3860 1878 1982 0 20 679 -/+ buffers/cache: 1178 2681 Swap: 2729 1035 1693 That's strange. Can someone explain this difference? But what is more important: I'd like to know how much memory a process is really using. I don't want to know the virtual memory size, but rather the resident memory plus swap of a process. I have also tried to output the format param "sz" of 'ps', but the sum of this is to high (5450 MB) (param 'size' gives 8323.45 MB). Are there any other options? I really want to use this, to determine which programs/processes are eating to much memory (and swap), to kill them, because hibernate might not be working if the swap partition is to little.

• Apache crashing at random intervals. Can not find a reason in log files

  - by Nick Downton

  We are having an issue with a VPS running plesk 9.5 on ubuntu 8.04 At seemingly random intervals Apache will disappear and needs to be started manually. I have checked the apache error log, /var/log/messages, individual virtual host apache error files and cannot find anything that coincides with the time of the failure. dmesg is empty which is a bit odd. We have also had the psa service go down for no apparent reason but apache stay up. I'm at a loss to diagnose this really because all the log files I can find do not point to any issues. Are there any others I can look at? Memory usage sits at about 55% (out of 400mb) and it isn't a particularly high trafficed server. Any pointers as to where else I can find out what is going on would be very much appreciated. Nick

• mosh-like port forwarding

  - by Marc Merlin

  This is on linux, connecting to linux servers: I love mosh, but it doesn't support port forwarding, and likely won't for a while since it's been almost a year now and it hasn't happened yet. port forwarding over ssh is great, but because my laptop moves between networks several times a day, my ssh sessions die, and so do the port forwards. I could script/hack something to detect hung ssh and reconnect to get my port forwards back, but before I do this, is there another way to do long lasting port forwards when your source IP changes several times daily (because you go on different networks)? I'm thinking an ssh over UDP would do the trick but of course ssh is over TCP.

I'm trying to find out why I get mysql server has gone error. One my windows machines apache it stops because of this issue. I have been trying to fine tune my mysql my.cnf with the following parameters but did not bring the desired result. # Instead of skip-networking the default is now to listen only on # localhost which is more compatible and is not less secure. bind-address = 0.0.0.0 # # * Fine Tuning # wait_timeout = 180 key_buffer = 384M max_allowed_packet = 64M thread_stack = 192K thread_cache_size = 8 # This replaces the startup script and checks MyISAM tables if needed # the first time they are touched myisam-recover = BACKUP max_connections = 500 table_cache = 64 #thread_concurrency = 10 # # * Query Cache Configuration # query_cache_limit = 1M query_cache_size = 32M how to debug this issue what is missing from configuration to avoid this error?

• Browsing is much slower on one PC wired to the same router - why?

  - by deanalt

  Wife is not happy. It takes about 5 seconds to open a google window, versus about 1 second on the faster computer which is about 3 years old itself. Yes, it is an older computer (5 -6 years old, I'd guess), surely with less RAM, but for simple browsing, should it matter? Both are hardwired to the same Netgear Rangemax router. Both use fixed IP addresses. Both are XP. Both have about 8 feet of cable to the router. I have the fastest service my cable provides. Probably irrelevant but ...two newer MACs are connected wirelessely during the summer and they are even faster, but I think that's the difference in browsers. If you could point me to a list of process of elimination steps that would be most appreciated. Thanks Dean

• Why do most routers not include local DNS?

  - by user785194

  I need to change my firewall/router, and I'd prefer something with built-in DNS to resolve queries on the local subnets. I've got a mixed Linux/Windows system, often with only one computer turned on, and I frequently have problems resolving local names. I don't want to keep a Linux box permanently on just for DNS, and I'd prefer to have DNS in my router appliance, which is always on. I search Google for this occasionally but never find anything. You always get the obvious answers - it's not possible, put everything in /etc/hosts, NetBIOS, dedicated box, etc. So what am I missing? Why don't "cheap" routers let you do this? I'm pretty sure that Cisco kit does this. Almost all cheap routers will let you do MAC address reservation, to let them assign static IP addresses for DHCP. So why can't they simply do DNS as well for everything on the local subnets, just passing through remote domains to the ISP?

• Configure iptables with a bridge and static IPs

  - by Andrew Koester

  I have my server set up with several public IP addresses, with a network configuration as follows (with example IPs): eth0 \- br0 - 1.1.1.2 |- [VM 1's eth0] | |- 1.1.1.3 | \- 1.1.1.4 \- [VM 2's eth0] \- 1.1.1.5 My question is, how do I set up iptables with different rules for the actual physical server as well as the VMs? I don't mind having the VMs doing their own iptables, but I'd like br0 to have a different set of rules. Right now I can only let everything through, which is not the desired behavior (as br0 is exposed). Thanks!

• Does setting an A record for a root domain set it (automatically) for subdomains?

  - by Edan Maor

  I bought a domain from Dreamhost, but my servers are actually running on Amazon's AWS. I have an Elastic IP, say 1.1.1.1. In the Dreamhost panel, I've added an A record for my domain name, pointing it to 1.1.1.1. My question is, are all subdomains (e.g. www.mydomain.com, a.mydomain.com, etc.) automatically mapped to 1.1.1.1 as well, because the root is? Or do I have to add separate rules for each subdomain?

• Configuring Bind9 on ubuntu

  - by Jerry

  I am trying to configure name server on Ubuntu just for learning. I have followed this tutorial. After configuring bind9 I have restarted it and works well. I have no registered domain name and public IP, so I have used a random domain name(khalidiitdu.com) that is not registered. When I dig khalidiitdu.com, it shows status: NXDOMAIN. If I use nslookup command, it shows ** server can't find khalidiitdu.com: NXDOMAIN. Now question is: Is registered domain mandatory to configure bind9 within a LAN? If not please suggest me alternative ways. Thanks.....
