• Computer hangs at boot screen with new RAID card

  - by shanethehat

  I am trying to build a new server around a Biostar TH61 motherboard and an Adaptec 6405E RAID controller card. The machine booted fine from USB before the RAID card and drives were installed. After installing, on the first boot the card was detected, but then started to spit out the following message every 10 seconds: Error: Controller Kernel Stopped Running << Press any key to continue ... Following the troubleshooting guide I unplugged everything, reseated the card, and reattached all the drives. This time the machine is sitting on the boot screen without any error messages and flashing a cursor, but after 15 minutes of this, nothing seems to be happening. Given that there are no error messages I'm hesitant to reboot again. Is it normal for a RAID card to sit without a status message when it firsts boots, maybe to initialise the drives or something? The current screen output looks a bit like this: Controller #00 found at PCI Slot:01, Bus:01, Dev:00, Func:00 Controller Model: Adaptec 6405E Firmware Version: 5.2-0[18512] Memory Size: 128MB Serial number: 111111111111111 SAS WWN: 50000D1104AE9180 _ Update: So after waiting 30 minutes I've rebooted back to the Kernal Stopped Running error. Maybe time to update the RAID BIOS.

• Write Fedora.iso to USB and boot it from a Macbook

  - by MTilsted

  I have an .iso image of the full Fedora 16 install (Downloaded from http://fedoraproject.org/en/get-fedora-options#formats as "Fedora 16 DVD") and the question now is: How do I write it on a USB stick, so I can install it on my Mac book? I tried using DD as the install guide said, and that gave me a USB stick which can boot from my PC. But it can't boot from the Mac (The Mac start menu don't show it as a boot option). Edit: I downloaded a live install image, and did this (SSD is my USB 4GB thing) /sbin/mkdosfs -F 32 -n usbdisk /dev/dev/sdd1 sudo livecd-iso-to-disk --format --reset-mbr --efi /tmp/download/Fedora-16-i686-Live-KDE.iso /dev/sdd1 And this produced an image which can boot on my pc but not on my mac. This seems to indicate that the --efi is not working, because if it really was EFI it would not boot on a normal pc, would it? I then tried this: (Difference being that I write the image directory to /dev/sdd instead of /dev/sdd1) but this still will not boot on the Mac (it newer shows up at the startup screen on the Mac). sudo livecd-iso-to-disk --format --reset-mbr --efi /tmp/download/Fedora- PS: My host Linux is Fedora 13.

• load average in top and procs in vmstat

  - by Mingfei.hua

  As far as I know, the load average in top is the numbers of precess(threads) in running or uninterrupted sleep status, So it should be equal to (procs-r +1 )+ procs-b in vmstat, but in practice, this two number always have big gap. Any wrongs in my understanding, appreciate so much if some guys give me some guide. top - 05:34:50 up 1 day, 20:56, 5 users, load average: 2.83, 2.67, 1.62 Tasks: 79 total, 1 running, 78 sleeping, 0 stopped, 0 zombie Cpu(s): 6.8%us, 1.8%sy, 0.0%ni, 91.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.4%st Mem: 1758000k total, 582636k used, 1175364k free, 103932k buffers Swap: 917500k total, 0k used, 917500k free, 180868k cached procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu----- r b swpd free buff cache si so bi bo in cs us sy id wa st 0 0 0 1182524 103784 180860 0 0 1 9 6 53 7 2 91 0 0 0 0 0 1182524 103784 180860 0 0 0 36 70 117 0 0 100 0 0 0 0 0 1182516 103784 180860 0 0 0 0 73 132 0 1 100 0 0 0 0 0 1182516 103784 180860 0 0 0 0 60 127 0 0 100 0 0 1 0 0 1182516 103784 180860 0 0 0 0 62 102 0 0 100 0 0 0 0 0 1182628 103784 180860 0 0 0 0 289 238 1 2 97 0 0 2 0 0 1152160 103784 180892 0 0 0 8 1481 2371 54 12 34 0 0 1 0 0 1182192 103784 180860 0 0 0 0 681 834 19 4 78 0 0 0 0 0 1182200 103784 180860 0 0 0 0 80 147 0 1 100 0 0 0 0 0 1182200 103784 180860 0 0 0 0 53 107 0 0 100 0 0 0 0 0 1182208 103788 180856 0 0 0 72 64 123 0 0 100 1 0

• Dell OpenManage On Ubuntu Server 12.04 Cannot Log In

  - by Austin

  I have a Dell Poweredge 2950 with 2X130GB and 2X2TB drives. I need to set them up in a RAID 1 array so that the 130GB Drives are mirrored and host the OS, while the 2TB drives are mirrored and are the content drives. So I go from 4 disks, down to two, one 130GB and one 2TB. I can do that in the BIOS RAID utility no problem. But I need to be able to manage the RAID arrays and be able to expand them WITHOUT shutting down the server. Now, to my understanding, openmanage will allow me to do that AND it runs on ubuntu. So I go and set it up and try to log into the web interface at and it will not let me log in. I have followed dell's guide to set up openmanage, even added the usernames to the files and permissions and such, however, cannot get it to let me log in or anything. I have reinstalled Openmanage several times, even reinstalled the OS three times, and nothing works. Google does not help either. It simply says login failed after hitting submit. Please Help

• Cannot start Postgres daemon after installing with Yum

  - by Sean the Bean

  I was trying to install Postgres 9.1.4 on Fedora 17 using Yum. If I do: sudo yum install postgres-libs sudo yum install postgres sudo yum install postgis All the installs appear to complete successfully (i.e., no errors), but I cannot start the Postgres daemon using: service postgresql initdb Like the official Postgres download guide says to do (http://www.postgresql.org/download/linux/redhat/). The error says Unknown operation initdb. RPM tells me that it installed psql to /usr/bin/, which I confirmed. It turns out that only a few components installed correctly (psql, pg_dump, pg_configure, and a few others), but most are missing (e.g., pg_ctl and postgres). I've tried several different configurations and had several of my coworkers (with more linux experience than me) look at it, but so far nothing has worked. Two of them have also run into similar issues installing Postgres using apt-get on Ubuntu, which makes me think the rpm isn't doing its job. It seems the only solution to build it from source, which is more robust anyway, but of course it takes longer. I'm wondering, though, if anyone else has run into this issue and/or has successfully installed Postgres on either Fedora or Ubuntu using a package manager like yum or apt-get? Is the rpm broken?

• Is this a solution for having multiple SSL certificates on the same IP

  - by Saif Bechan

  I am running CentOS running on a VPS. I read some guides on having multiple SSL certificates on the same system, but I can not get the basics to work. The guide I got that makes the most sense to me is the doing the following. In CentOS I can make virtual NIC's. So I made 2 virtual NIC's to start with. 192.168.10.1, 192.168.10.2. Now I work in ISP manager Pro, so this is listening on my primary ip 1.1.1.1 For each website I have them listening on 192.168.10.1:80, 192.168.10.1:443 In the hosts file I made the following 2 entries 192.168.10.1 1st.com 192.168.10.2 2nd.com Now the strange thing is that when I browser to 1st.com I do not get the website located at 192.168.10.1, I get the website located at my prim IP 1.1.1.1 Should I do something like forwarding or routing for this setup to work? And the basic question: Will this setup even work? Are the SSL certificates based on the IP adress, or are the based on the host name, 1st.com and 2nd.com.

• One USB flash drive to rule them all

  - by Chris

  Yesterday I purchased a 32GB USB flash drive. I have a myrid of systems in my home, and would like to have one flash drive with setup files for all the various systems throughout the house. I kept the Fat 32 filesystem on the drive, as I figured that is probably the most universal. I then made the partition bootable using fdisk. I then copied the Windows 7 setup files to the drive. I then installed grub 2 (1.98) onto the drive using backtrack 5. I was then able to load the windows 7 setup / install from the flash drive on an older BIOS type motherboard. Now I would like to know how to get this to work on my MacBook Pro 8,2 with still retaining support for legacy computers. Is this possible, or is this just a pipe dream. I plan on getting OS X on the drive, gparted, and OS X86 on the drive when all is said and done. I've done various google searches but really haven't found a guide on how to setup a swiss army usb flash drive.

• a VPS mail server

  - by microspino

  Hello I'm trying to substitute citadel on my Virtual Private Server with something more simple. I dislike their documentation and the webmail client. I don't need any groupware feature. I need only an MTA with a nice looking web interface, SPAM and VIRUS check. I recently found the lamson project from Zed Shaw. Is that production ready? Do you had any real and good experience with It? On the latest-news page I see that the last release dates december 2009. Sorry for my lack of knowledge, I'm really new to mail servers but I have to find a solution to manage sending and receiving mail on my VPS. I would accept also to build my VPS email server using a linux system like exim, postfix or whatever but I have really small needs and they will not grow in at least a year and i will be the only one user. I'm searching for something that I could build and manage easily, as I'm a novice linux sysadmin. Having also some good documentation or at least a robust step by step guide would be a plus.

• Issues with VPN functionality

  - by Xorandor

  I've been working on setting up VPN connectivity to our office location. We bought a Cisco WRV210 which have a builtin VPN server. Cisco has some software QuickVPN, which is not as quick and easy as I had thought. I've had mixed experiences on different machines with connecting. Instead I configured an IPSec VPN tunnel following a guide from TheGreenBow here http://www.thegreenbow.com/doc/tgbvpn_cg_linksys_wrv200_en.pdf I followed their instructions and tried out an evaluation of their software, and VPN connection should be working ok. I'm able to do RDP to a machine on the network (using IP address, not machine name) and ping the router etc. What I'm trying to solve are two things: It's not like I'm "really" on the network. Or at least I'm restricted to some degree when going through the VPN. I can't access a machine on the network using machine name, only IP. I can't ping a machine, but the router just fine. Could this be that something is not set up properly? If so, I can ofcourse supply additional information. Second, when I log onto the VPN, I would really like my outgoing connection to go through the internet connection of the remote location. Basically if I connect to the VPN I want my outgoing IP to be that of the remote location's (needed for some IP resctrictions on some of our servers). At a previous work location it worked like this when we connected to our office VPN over PPTP and the builtin windows VPN client. I'm not a huge expert on the topic, so any hints will be appreciated.

• bootmgr image is corrupt

  - by bacord

  I just replaced my HD with a SSD. I did a brand new install on the SSD and I received the following error after booting BOOTMGR image is corrupt. The system cannot boot. A little configuration for your knowledge. The system used to be a dual boot with XP & windows 7. After replacing the original startup HD with my SSD I changed a setting in the bios to AHCI (I have tested changing it back but this did not help). When I look at the stats on the drive in the bios, it claims that the SSD is in a raid configuration despite the settings not being configured that way. Related System Information: Intel 320 Series 80 GB Sata II SSD JetWay JPA78VM3-H-LF AM2+/AM2 AMD 780V HDMI Micro ATX AMD Motherboard AMD Athlon 64 X2 7 GB ram I have performed 2 fresh installs to no avail. Also, followed this guide and performed option 1 and 2. I have done bootsec/fixmbr and /fixboot. So.. any suggestions?

• Juniper’s Network Connect ncsvc on Linux: “host checker failed, error 10”

  - by hfs

  I’m trying to log in to a Juniper VPN with Network Connect from a headless Linux client. I followed the instructions and used the script from http://mad-scientist.us/juniper.html. When running the script with --nogui switch the command that gets finally executed is $HOME/.juniper_networks/network_connect/ncsvc -h HOST -u USER -r REALM -f $HOME/.vpn.default.crt. I get asked for the password, a line “Connecting to…” is printed but then the programm silently stops. When adding -L 5 (most verbose logging) to the command line, these are the last messages printed to the log: dsclient.info state: kStateCacheCleaner (dsclient.cpp:280) dsclient.info --> POST /dana-na/cc/ccupdate.cgi (authenticate.cpp:162) http_connection.para Entering state_start_connection (http_connection.cpp:282) http_connection.para Entering state_continue_connection (http_connection.cpp:299) http_connection.para Entering state_ssl_connect (http_connection.cpp:468) dsssl.para SSL connect ssl=0x833e568/sd=4 connection using cipher RC4-MD5 (DSSSLSock.cpp:656) http_connection.para Returning DSHTTP_COMPLETE from state_ssl_connect (http_connection.cpp:476) DSHttp.debug state_reading_response_body - copying 0 buffered bytes (http_requester.cpp:800) DSHttp.debug state_reading_response_body - recv'd 0 bytes data (http_requester.cpp:833) dsclient.info <-- 200 (authenticate.cpp:194) dsclient.error state host checker failed, error 10 (dsclient.cpp:282) ncapp.error Failed to authenticate with IVE. Error 10 (ncsvc.cpp:197) dsncuiapi.para DsNcUiApi::~DsNcUiApi (dsncuiapi.cpp:72) What does host checker failed mean? How can I find out what it tried to check and what failed? The HostChecker Configuration Guide mentions that a $HOME/.juniper_networks/tncc.jar gets installed on Linux, but my installation contains no such file. From that I concluded that HostChecker is disabled for my VPN on Linux? Are the POST to /dana-na/cc/ccupdate.cgi and “host checker failed” connected or independent? By running the connection over a SSL proxy I found out that the POST data is status=NOTOK (Funny side note: the client of the oh-so-secure VPN does not validate the server’s SSL certificate, so is wide open to MITM attacks…). So it seems that it’s the client that closes the connection and not the server.

• Rename Active Directory domain following Windows 2000 -> 2008 migration.

  - by ewwhite

  I'm working with a site that needs an internal DNS domain rename. It currently has a DNS name of domain.abc.com and NT name of ABC. I'm trying to get to a DNS name of abctrading.com and NT name of ABCTRADING. Split DNS would be used. The site originally ran from a single Windows 2000 domain controller hosting AD, file, print, DHCP and DNS services. There was no Exchange system in the environment. The 50 client PCs are all Windows XP with a handful of users using roaming profiles. All users are in a single OU and there are no group policy/GPOs. I'm a Linux engineer, but have been trying to guide another group of consultants to reach a more suitable setup. With the help of this group, we were able to move the single Windows 2000 system to a set of Windows 2008 R2 servers separated into domain controller and file/print systems (virtualized). We are also trying to add an Exchange 2010 system to this mix. The Windows 2000 server was demoted and is no longer in the picture. This is the tricky part, as client wants the domain renamed and the consultants aren't quite sure how to get through it without another 32-40 hours of testing/implementation. THey say that there's considerable risk to do the rename without a completely isolated test environment. However, this rename has to be done before installing Exchange. So we're stuck at this point. I'd like to know what's involved in renaming the domain at this point. We're on Windows Server 2008. The AD is healthy now. Coming from a Linux background, it seems as though there should be a reasonable path to this. Also, since the original domain appears to be a child/subdomain, would that be a problem here. I'd appreciate any guidance.

• Do I need to restart my server after editing fstab and mtab?

  - by jaypabs

  I'm just wondering if I need to restart my server after editing fstab and mtab. I changed something in this file manually due to problem with awstats report. I am using ISPConfig 3 with the help of the tutorial from howtoforge. But due to removing/deleting of some account, the configuration of fstab and mtab messed up. I also ask this question at howtoforge forum but until now no one has answered. If you'd like to read my question please visit it here. I tried very hard to fix the problem w/o luck. Update: Here's what happen to my fstab: Before the value was (I omitted the other): /var/log/ispconfig/httpd/mydomain.com /var/www/clients/client1/web1/log none bind,nobootwait 0 0 /var/log/ispconfig/httpd/example.com /var/www/clients/client1/web2/log none bind,nobootwait 0 0 So I changed it to the correct path: /var/log/ispconfig/httpd/mydomain.com /var/www/clients/client1/web2/log none bind,nobootwait 0 0 /var/log/ispconfig/httpd/example.com /var/www/clients/client1/web3/log none bind,nobootwait 0 0 I also found mtab to have the same value as above that's why I edited it manually. from: /var/log/ispconfig/httpd/mydomain.com /var/www/clients/client1/web1/log none rw,bind 0 0 /var/log/ispconfig/httpd/example.com /var/www/clients/client1/web2/log none rw,bind 0 0 to: /var/log/ispconfig/httpd/mydomain.com /var/www/clients/client1/web2/log none rw,bind 0 0 /var/log/ispconfig/httpd/example.com /var/www/clients/client1/web3/log none rw,bind 0 0 I edited those value because the correct path of mydomain.com and example.com should be under web2 and web3 folder respectively. As of now the log of example.com is pointed to: /var/www/clients/client1/web2/log when it should be: /var/www/clients/client1/web3/log So I am thinking that this is because of fstab and mtab. Please guide me how to point the log correctly to it's default directory. I explain the scenario one by one at this link. to dawud: Based on your example mount -o remount,noexec /var, should I run mount -o remount,noexec /var/log/ispconfig/httpd/example.com?

• how to go about scaling a web-application ?

  - by phoenix24

  for someone whoes been primarily a web-application developer, and know not much about scaling/scalability techniques. I'll start by stating my application is written in Python, using Django; a fairly standard setup. I currently use Apache 2.2 for my webserver, and MySql for my database server; both running on the same vps server. Up until now, it was basically a prototype and merely 15-30 concurrent users at any given time; so I had no issues, but now since we'll be adding more users we'll have severe performance issues. So my question is how do i go about scaling my web-application? and my plan is as follows. Now I have just one vps server running, apache + mysql. Next, I plan to add another vps server, to run only MySql; so i'll have one web-server and one db server. Next, I'll add Memcache to the webserver for caching data; and taking some load off mysql. Next, another web-server for serving all the static content; Next, a vps server for load-balancing (nginx/varnish) behind which would be my two web-servers and then db-server. Does that sound like a workable strategy, please guide me around here.

• iptables captive portal remove user

  - by Burgos

  I followed this guide: http://aryo.info/labs/captive-portal-using-php-and-iptables.html I am implementing captive portal using iptables. I've setup web server and iptables on linux router, and everything is working as it should. I can allow user to access internet with sudo iptables -I internet -t mangle -m mac --mac-source USER_MAC_ADDRESS -j RETURN and I can remove access with sudo iptables -D internet -t mangle -m mac --mac-source USER_MAC_ADDRESS -j RETURN However, on removal, user can still open last viewed page as many times he wants (if he restart his Ethernet adapter, future connections will be closed). On blog page I found a script /usr/sbin/conntrack -L \ |grep $1 \ |grep ESTAB \ |grep 'dport=80' \ |awk \ "{ system(\"conntrack -D --orig-src $1 --orig-dst \" \ substr(\$6,5) \" -p tcp --orig-port-src \" substr(\$7,7) \" \ --orig-port-dst 80\"); }" Which should remove their "redirection" connection track, as it is written, but when I execute that script, nothing happens - user still have access to that page. When I execute /usr/sbin/conntrack -L | grep USER_IP after executing script I am having nothing returned, so my questions: Is there anything else that can help me clean these track? Obviously - I can't reset nor mine, nor users network adapter.

• Pair programming with tmux and Vagrant

  - by neezer

  Does anyone have a clear step-by-step guide for setting up a shared tmux session on a Vagrant vbox that my coworkers (on our local office lan) could SSH into? The articles I've found online only seem to cover setting this up from machine to machine (no virtualbox setups), and I'm not very good at networking, so I haven't been able to extrapolate a solution... We're all running the latest Macs in our office, btw. Here's one article I've found but haven't been able to get working with Vagrant: http://blog.voxdolo.me/remote-pairing-with-vim-and-tmux.html EDIT: To clarify, I don't really know how I should be setting up Vagrant to allow me to SSH into it from a machine outside the one hosting the VM. The article above suggests that I add the tunnels host on my physical machine running the VM (here-on referred to as the MBP), so I did that. Next is the ProxyCommand host declaration, which I have also assumed should live on the MBP. So next I try SSHing into the MBP from a guest machine (another separate physical machine on my network), and that seems to work... but that only gets me into the MBP, not the Vagrant image running on the MBP. I normally login Vagrant image on the MBP via vagrant ssh (per the docs), and I know how to forward ports on the Vagrant VM to the MBP, but it's unclear to me how I could forward ports/SSH from the MBP to the Vagrant VM, which I assume I would need to do so that my guest machine could SSH in--through the MBP--to my Vagrant image. That, in a nutshell, is what I'm trying to accomplish. I do my development work in Vagrant VMs which keeps my MBP nice and clean of any dev-related cruft and also keeps my dev environments totally isolated from one another, yet I would like to start pair-programming with my coworkers via tmux, thus the reason why I've asked this question. I would like to accomplish all of this without setting up an additional user account on the MBP, or giving my coworkers access to my local user account on the MBP to get to my Vagrant VM, if that's at all possible.

• PHP cannot connect to MySQL

  - by yogal

  Hello, I recently installed Apache 2 + PHP 5.3.1 + MySQL 5.1.44 on my Windows 7 64bit machine following this guide: http://sleeplessgeek.blogspot.com/2010/01/setting-up-apache-php-mysql-phpmyadmin.html It all went fine, php is working great (even with XDebug) but I cannot connect to mysql server. A simple script I wrote to test connection (yes, root has no pass): $username = "root"; $password = ""; $database = "test"; $hostname = "localhost"; $conn = mysql_connect($hostname, $username, $password) or die("Unable to connect to MySQL Database!!"); It prints this error after 60sec of timeout: Warning: mysql_connect() [function.mysql-connect]: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. I can connect to mysql using cmdmysql -h localhost -u root Services are working properly. There also seems to be a problem with PhpMyAdmin (using 3.2.5). As soon as I type user and pass the page loads and turns blank (content-lenght in headers is 0 but status code is 302 Found). Looks like something wrong with cookies (my auth method). I hope someone has a clue, it has to be something dumb simple I missed. Thanks in advance.

• DRBD Replication failure

  - by user62513

  A couple of weeks ago I setup a 2 nodes CRM system with one of the resources managed being MySQL over DRBD. Today for maintenance reasons I restarted both nodes but now they can't connect to each other anymore. DRBD fell out of sync and I followed this guide to get it back connected but it's only able to run successfully on one node. But this strange thing happens: If I crm node standby both nodes and I try: crm node online node0 before crm node online node1, all the CRM resources start successfully but the DRBD partitions are still running in StandAlone state. crm node online node1 beofre crm node online node0, the DRBD resource fails to start, thus causing mysql not to start. If I standby both resources and call crm node online node0 then it times out and prints this error: Running crm node online node0 produces this output after timing out Error setting standby=off (section=nodes, set=<null>): Remote node did not respond Error performing operation: Remote node did not respond Is there anything I'm doing wrong here? An alternative will be just do MySQL replication but I'm not sure how to promote a slave to master when the master database is not available.

• Juniper SSG 5 VPN

  - by Ethabelle

  I have a host who set up our Juniper SSG 5 VPN with Firmware version-6.2.0r5.0 I've been trying to set up VPN on it using this guide: http://kb.juniper.net/InfoCenter/index?page=content&id=KB4094 I've followed the steps and on my Mac, whenever I try to connect using L2TP over IPSec I get the following error; Summary of Steps: Create User (give them L2TP auth ability), Create Group, Place User in Group, Create VPN Gateway, Create VPN, create IP Pool, change default L2TP settings, create Untrust Trust Policy. The L2TP-VPN server did not respond. Try reconnecting. If the problem continues, verify your settings and contact your Administrator. I looked in my Firewall's logs, but I don't even see anything under Reports Logs Events. I'm.. obviously missing something, I just don't know what I'm missing at this point. I'm just starting networking and this is sort of Step 101 and I'm getting annoyed and just want to throw up OpenVPN, but I've read that has problems with Juniper Firewalls. Hooray.

• VPN Setup: Mac OS X and SonicWall

  - by noloader

  I'm trying to get VPN access up and running. The company has a SonicWall firewall/concentrator and I'm working on a Mac. I'm not sure of the SonicWall's hardware or software level. My MacBook Pro is OS X 10.8, x64, fully patched. The Mac Networking applet claims the remote server is not responding. The connection attempt subsequently fails: This is utter bullshit, as a Wireshark trace shows the Protected Mode negotiation, and then the fallback to Quick Mode: I have two questions (1) does Mac OS X VPN work in real life? (2) Are there any trustworthy (non-Apple) tools to test and diagnose the connection problem (Wireshark is a cannon and I have to interpret the results)? And a third question (off topic): what is broken in Cupertino such that so much broken software gets past their QA department? EDIT (12/14/2012): The network guy sent me "VPN Configuration Guide" (Equinox document SonicOS_Standard-6-EN). It seems an IPSec VPN now requires a Firewall Unique Identifier. Just to be sure, I revisited RFC 2409, where Main Mode, Aggressive Mode, and Quick Mode are discussed. I cannot find a reference to Firewall Unique Identifier. I think I am screwed here: I am trying to connect to a broken (non-standard) firewall, with a broken Mac OS X client. Fortunately, I can purchase VPN Tracker Personal (a {SonicWall|Equinox}-authored client) for $129US from Equinox. So much for standards....

• Is VGA port hot-pluggable?

  - by Martin Bøgelund

  In meetings, I often see people detaching the VGA connector from one running laptop and connecting it to another, while the projector is still on. Is this 100% risk free, and OK by design of the VGA standard? If there's a risk involved in hot-plugging VGA, can it be removed by turning off or suspending either laptop, display, or both? I see this being done all the time without causing disaster, so clearly I'm not interested in answers stating "we do it all the time, so it should be OK!". I want to know if there's a risk - real or in theory - that something breaks when doing this. EDIT: I did an internet search on the topic, and I never found a clear statement as to why it is safe or unsafe to hot swap VGA devices. The typical form is a forum question asking basically the same question as I did, and the following types of statements Yes it's hot swappable! I do it all the time! It involves some kind of risk, so don't do it! You're some kind of moron if you think there's a risk, so just do it! But no explanation as to why it safe or not... Joe Taylors answer below contains a link to a forum post and answers that basically give me the same statements as mentioned above. But again, no good explanation why. So I looked for an actual manual for a projector, and found "Lenovo C500 Projector User’s Guide". It states on page 3-1: Connecting devices Computers and video devices can be connected to the projector at the same time. Check the user’s manual of the connecting device to confirm that it has the appropriate output connector. [image] Attention: As a safety precaution, disconnect all power to the projector and devices before making connections. But again, no good explanation.

• How do I install Windows XP from an external hard drive?

  - by Plasmer

  I'm trying to install Windows XP Media Center edition by copying the install disc image to an external hard drive and making it bootable. Has anyone had success getting this to work on systems that can't boot from dvds/floppies? I'm basically working from this guide: http://www.dl4all.com/other/21495-install-windows-xp-from-usb.html Update - 2/15/10 I used WinToFlash on my laptop to format my usb hard drive from my install dvd (Windows XP Media Center Version 2005 with Update Rollup 2 from Dell) and selected "boot from usb device" at the boot selection menu and the windows installer started up. However, an error message came up saying that: "A problem has been detected and windows has been shut down to prevent damage to your computer." Originally on my desktop machine, I had 1 150Gb SATA drive, and 2 150 Gb SATA drives striped together using RAID. From the hard drive diagnostics, it appears the windows install on one of the RAIDed disks lost a block and this has been preventing me from booting up. I replaced the standalone drive with a new 1Tb SATA drive and disconnected the other hard drives. Could the message be indicating a virus is on the unformatted drive? or the usb hard drive? Update 2 - 2/15/10 The external hard drive didn't find any viruses when scanned. I tried installing Vista Home Premium 64bit SP1 using WinToFlash and that installed successfully onto the new 1Tb drive. WinToFlash was really easy to use and helped a lot, thanks!

• EMC VNX iSCSI setup - unsure about SP/port assignment

  - by pauska

  We have a new VNX5300 waiting to get configured, and I need to plan out the network infrastructure before the EMC tech arrives. It has 4x1gbit iSCSI per SP (8 ports in total), and I'd like to get the most out of the performance until we jump over to 10gig iSCSI. From what I can read from the docs - the recommendation is to use only two ports per SP, with 1 active and 1 passive. Why is this? It seems kind of pointless to have quad-port i/o-modules and then recommend to not use more than two of them? Also - I'm a bit unsure about the zoning. The best practices guide state that you should separate each port on each SP from each other on different logical networks. Does this mean that I have to create 4 logical networks to be able to use all 8 ports? It also gives the following example: Does this mean that A0 and B0 should sit on the same physical switch aswell? Won't this make all traffic go on one switch (if both A1 and B1 are passive)? Edit: Another brainpuzzle I don't get it - each host (as in server) should not have more iSCSI bandwidth available than the storage processor. What on earth does this matter? If serverA have 1gbit and serverB have 100mbit, then the resulting bandwith between them is 100mbit. How can this result in some kind of oversubscription? Edit4: Wait, what. Active and passive ports? The VNX runs in a ALUA configuration with asymmetrical active/active.. there shouldn't be any passive ports, only preferred ones..

• LG LW20 Express won't boot after hdd replace

  - by Mika

  My old laptop (LG LW20 Express) got a hdd failure and I replaced the hdd. Now the laptop won't boot from cd or usb. I'm trying to install ubuntu on it. When I turn the laptop on it shows me the startup screen but when it should be the time to load operating system it just gives a black screen and starts over. This loop continues until I shut down the laptop. I created the usb boot drive following this guide https://help.ubuntu.com/community/Installation/FromUSBStick/ I used my boot cd to install ubuntu on this machine I'm using right now. So at least the cd should work. From the BIOS I can see that my newly installed hdd is recognized and put as a secondary master. Also the cd and removable media are in the boot list before hdd. The laptop runs pretty hot. The fan is at full speed pretty soon after the laptop is turned on. Earlier I suspected that it would have been the almost broken hdd that would have produced that heat but there obviously is something else also. Any ideas what to check?
