• Extend Linux Desktop to another X Windows Display

  - by unknown (google)

  Hello, I am a long time Linux user of the Xinerama and other technologies for extending a desktop to multiple monitors. However when I travel with my laptop I miss the multi-monitor support I enjoy at home. Recently I acquired a second laptop for a low price. Both laptops are running Fedora (versions 10 and 11 respectively). I use Gnome as my primary desktop environment. I know about synergy. I use synergy all the time to control the screen of other Windows / Linux systems I use. I would like to know, can I sit both my primary and secondary laptops together and achieve a Xinerama-like extended desktop environment? Ideally I would like to start a GNOME session on my primary laptop. And then start a X-Windows Desktop on my secondary laptop and extend my primary laptop's desktop onto it. I would like to be able to move Windows from the primary desktop to the secondary laptop desktop. Would I need to use synergy to do this with some other bit of X-Windows technology? Or is there X-Windows technology that will do all this for me? I am familiar with X Windows ability to display applications remotely. I am also familiar with Nomachine's NoX.

• Simple Distributed Disconnected way to sync a directory

  - by Rory

  I want to start regularly backup my home directory on my ubuntu laptop, machine X. Suppose I have access to 2 different remote (linux) servers that I can backup to, machines A & B. Machine X will be the master, and should be synced to A and B. I could just regularly run rsync from X to A and then from X to B. That's all I need. However I'm curious if there's a more bandwidth effecient, and hence faster way to do it. Assuming X is going to be on residential style broadband lines, and since I don't want to soak up the bandwidth, I would limit the transfer from X. A and B will be on all the time, however X, will not be, so I'd also like to reduce the amount of time that X is transfering, potentially allowing A and B to spend more time transfering. Also, X won't be connected all the time. What's the best way to do this? rsync from X to A, then from A to B? Timing that right could be troublesome. I don't want to keep old files around, so if I was to rsync, then the --del option would be used. Could that mean something might get tranfered from A to B, then deleted from B, then transfered from A to B again? That's suboptimal. I know there are fancy distributed filesystems like gluster, but I think that's overkill in this case, and might not fit with the disconnected nature.

• Is it ok to share private key file between multiple computers/services?

  - by Behrang

  So we all know how to use public key/private keys using SSH, etc. But what's the best way to use/reuse them? Should I keep them in a safe place forever? I mean, I needed a pair of keys for accessing GitHub. I created a pair from scratch and used that for some time to access GitHub. Then I formatted my HDD and lost that pair. Big deal, I created a new pair and configured GitHub to use my new pair. Or is it something that I don't want to lose? I also needed a pair of public key/private keys to access our company systems. Our admin asked me for my public key and I generated a new pair and gave it to him. Is it generally better to create a new pair for access to different systems or is it better to have one pair and reuse it to access different systems? Similarly, is it better to create two different pairs and use one to access our companies systems from home and the other one to access the systems from work, or is it better to just have one pair and use it from both places?

• Problems forwarding port 3306 on iptables with CentOS

  - by BoDiE2003

  Im trying to add a forward to the mysql server at 200.58.126.52 to allow the access from 200.58.125.39, and Im using the following rules (its my whole iptables of the VPS of my hosting).

• Wireless Access Point stopped working

  - by Alex Pritchard

  I have a simple LAN set up at home using a Linksys WRT54GSV4 as my primary router and an Encore ENHWI-2AN3 as an access point. I connect the Encore to the Linksys by running a cable from one of the Linksys LAN ports into the Encore WAN input. I originally configured this using the Encore setup wizard, setting the device up in AP Router Mode. It detected the input network and worked about as expected, creating a second network that used my primary network to connect to the internet. It worked fine for about 2 weeks, then abruptly cut out today. I checked to make sure the network was still live through the cable going into the Encore (provides internet when connected to a laptop directly) and that devices are still able to connect to the network being broadcast by the Encore. When I try to rerun the connection wizard on the Encore, I receive the message "No Services found in WAN port." The WAN Settings is no longer retrieving a dynamic ip from the line. I tried providing a static IP, assigning an IP address within the subnet range of my primary router that wasn't being used and pointing the Default Gateway to the Linksys IP, but this did not work either. When I plug the cable into the WAN port, an internet light comes on that is not lit when a live network is not connected. I've tried doing a hard reset on the Encore (held down the rest button until the lights flashed, reconfigured from scratch), but the WAN settings are still not detected. Also tried powering off and on the modem, linksys, and encore. Any suggestions would be appreciated!

• PHP application failed to connect after a network plugged back in

  - by tntu

  My data-center appears to have had some issues with their network and thus my server has suffered from on an off network connectivity for about an hour. After the connection has been completely re-established my code still kept reporting the same issue over and over until I have restarted the service. The code is a simple PHP code that loops forever checking the Apple feed-back server and then sleeps for a few minutes and then it begins all over again. Now I understand the error being generated if the network is down but once it got back up why did it continue until I have restarted the code? Does PHP have something that needs to be re-initialized or something??

• Connecting SVN from Remote Server

  - by Ashish

  I have hosted my repository in assebbla & it works fine. now I want to write a script that can automate the build process : 1. Take the code from assembla repository 2. Make a dump and copy it onto my web server. what I have researched from net states that use of commands like svn co svn+ssh://[email protected]/home/svn/test I believe I need to open Shell on my server and type these commands but shell has been disabled from my server admin. I tried to run the same from php using exec , admin has disabled that too. (am using shared hosting and want to do a automated deployment using these simple steps. i don't want to bring my local system in this process) now am not sure even if I get the shell access open to my server these commands like svn will work there as I don't have SVN installed on my server (its installed on assembla). kindly let me know if any more explanation is required regarding the same or if am going on the wrong track. Am a newbie so please be descriptive in answering :) Thanx in advance Ace

• Recover data from hard drive with partitions (but not most data) overwritten

  - by Macha

  I have a 500GB hard drive I've been keeping around to recover data from that I removed from a failing NAS drive that got sort of... erratic at the end. I finally got rid of the NAS when during a firmware update it removed the partition table. Fast forward to a week ago, when I was building a new PC, and a mixup resulted in me placing the hard drive in question in the new PC and installing Windows XP on the first 100GB. I'm presuming any data on that first 100GB is now gone, but for the rest of it, is there any way I can recover it at home, as professional data recovery is currently too expensive? I have a blank 1TB HDD if I can store any images of that hard drive on. The problem was definitely with the NAS and not the hard drive, as the hard drive had a successful install of Windows when mistakenly place in the new PC, and there were capacitors in the NAS's circuitry clearly broken. The data I want to recover (in order of priority) is: High: Some jpgs of family photos. Medium: Some RAW files. (There are also jpg versions of all of these) Low: Some mp3s, avis and ISOs, I can re-rip most of these if need be, but it'd be handy not to have to. (I don't need a backup lecture, and if you can hold it in from nagging Jeff Atwood for it, you can hold it in from nagging me for it) In short: The partition tables are gone and overwritten. The data is not overwritten, except for an amount equal to the size of a Windows XP SP3 installation.

• Virtual box host-only adapter configuration

  - by Xoundboy

  I have VirtualBox 4 running on Win 7 with a Centos 6 guest VM set up for hosting my dev server. When I'm connected to my home network the guest can be accessed via a static IP address that I configured (192.168.56.2), but not when I'm in the office. I'm guessing that the DHCP server in the office doesn't have a gateway configured for the 192.168.56.x IP range. I read something about the VB host-only adapter that should allow me to set this guest VM up in such a way that I don't need to be on any network to be able to access the guest from the host using a static IP. I've not been able to find out exactly how to configure this though. Can anyone give me an example configuration, thanks. UPDATE: Thanks for your responses. I've now set up a single virtual network adapter in VirtualBox and set it to host-only: C:\Users\Ben>vboxmanage list hostonlyifs Name: VirtualBox Host-Only Ethernet Adapter GUID: d419ef62-3c46-4525-ad2d-be506c90459a Dhcp: Disabled IPAddress: 192.168.56.2 NetworkMask: 255.255.255.0 IPV6Address: fe80:0000:0000:0000:78e3:b200:5af3:2a57 IPV6NetworkMaskPrefixLength: 64 HardwareAddress: 08:00:27:00:94:e8 MediumType: Ethernet Status: Up VBoxNetworkName: HostInterfaceNetworking-VirtualBox Host-Only Ethernet Adapter On the guest I've set up eth0 to use the same IP address as the host-only adapter (192.168.56.2) but when I try to log in using Putty I still get "Network Error : connection refused". VirtualBox DHCP servier is enabled but I can't ping the gateway (192.168.56.1) from either host nor guest. There's no firewall running on either OS. What next?

• How to reduce celeryd memory consumption?

  - by Gringo Suave

  I'm using celery 2.5.1 with django on a micro ec2 instance with 613mb memory and as such have to keep memory consumption down. Currently I'm using it only for the scheduler "celery beat" as a web interface to cron, though I hope to use it for more in the future. I've noticed it is the biggest consumer of memory on my micro machine even though I have configured the number of workers to one. I don't have many other options set in settings.py: import djcelery djcelery.setup_loader() BROKER_BACKEND = 'djkombu.transport.DatabaseTransport' CELERYBEAT_SCHEDULER = 'djcelery.schedulers.DatabaseScheduler' CELERY_RESULT_BACKEND = 'database' BROKER_POOL_LIMIT = 2 CELERYD_CONCURRENCY = 1 CELERY_DISABLE_RATE_LIMITS = True CELERYD_MAX_TASKS_PER_CHILD = 20 CELERYD_SOFT_TASK_TIME_LIMIT = 5 * 60 CELERYD_TASK_TIME_LIMIT = 6 * 60 Here's the details via top: PID USER NI CPU% VIRT SHR RES MEM% Command 1065 wuser 10 0.0 283M 4548 85m 14.3 python manage_prod.py celeryd --beat 1025 wuser 10 1.0 577M 6368 67m 11.2 python manage_prod.py celeryd --beat 1071 wuser 10 0.0 578M 2384 62m 10.6 python manage_prod.py celeryd --beat That's about 214mb of memory (and not much shared) to run a cron job occasionally. Have I done anything wrong, or can this be reduced about ten-fold somehow? ;) Update: here's my upstart config: description "Celery Daemon" start on (net-device-up and local-filesystems) stop on runlevel [016] nice 10 respawn respawn limit 5 10 chdir /home/wuser/wuser/ env CELERYD_OPTS=--concurrency=1 exec sudo -u wuser -H /usr/bin/python manage_prod.py celeryd --beat --concurrency=1 --loglevel info --logfile /var/tmp/celeryd.log Update 2: I notice there is one root process, one user child process, and two grandchildren from that. So I think it isn't a matter of duplicate startup. root 34580 1556 sudo -u wuser -H /usr/bin/python manage_prod.py celeryd wuser 577M 67548 +- python manage_prod.py celeryd --beat --concurrency=1 wuser 578M 63784 +- python manage_prod.py celeryd --beat --concurrency=1 wuser 271M 76260 +- python manage_prod.py celeryd --beat --concurrency=1

• Without an internet connection my computer loads programs slowly. With an internet connection they load quickly

  - by Peter pete

  Gday. I've a laptop, with 8gb of RAM and a Samsung 830 SSD with about 2/5th of free space out of its 256gb. Win7 64b. Laptop is a Toshiba T130. In the other day I noticed that it took a long time to load a program, for example the python interpreter at the time the computer didn't have access to the home network. In both cases the computer boots quickly. About 40 seconds. Without internet opening the python interpreter, or notepad2.exe, or any program individually takes around 10 seconds. With internet connection (through WiFi) opening the same programs takes about 2 seconds. In both cases, it becomes SSD-instant-quick to open a program from a cold boot. I don't have any network mapped drives. I've tried with AV off (Avast antivirus) and same effect. I've installed all MS updates. I've googled and googled and have found nothing of help. I've run the Samsung SSD magician to "optimise" ssd and that didn't help. What could I do to determine & fix this issue?

• KVM virtual machine unable to access internet

  - by peachykeen

  I have KVM set up to run a virtual machine (Windows Home Server 2011 acting as a build agent) on a dedicated server (CentOS 6.3). Recently, I ran updates on the host, and the virtual machine is now unable to connect to the internet. The virtual network is running through NAT, the host has an interface (eth0:0) set up with a static IP (virt-manager shows the network and its IP correctly), and all connections to that IP should be sent to the guest. The host and guest can ping one another, but the guest cannot ping anything above the host, nor can I ping the guest from anywhere else (I can ping the host). Results from the guest to another server under my control and from an external system to the guest both return "Destination port unreachable". Running tcpdump on the host and destination shows the host replying to the ping, but the destination never sees it (it doesn't even look like the host is bothering to send it on at all, which leads me to suspect iptables). The ping output matches that, listing replies from 192.168.100.1. The guest can resolve DNS, however, which I find rather odd. The guest's network settings (connection TCP/IPv4 properties) are set up with a static local IP (192.168.100.128), mask of 255.255.255.0, and gateway and DNS at 192.168.100.1. When originally setting up the vm/net, I had set up some iptables rules to enable bridging, but after my hosting company complained about the bridge, I set up a new virtual net using NAT and believe I removed all the rules. The VM's network was working perfectly fine for the last few months, until yesterday. I haven't heard anything from the hosting company, didn't change anything on the guest, so as far as I know, nothing else has changed (unfortunately the list of packages updated has since fallen off scrollback and I didn't note it down).

• Can I charge USB devices from a powered hub that isn't connected to a PC?

  - by Anodyne

  This will probably sound familiar to most of you... In my home, we have a whole bunch of devices that can be charged via USB (two iPhones, a BlackBerry, an iPod Touch, etc ad nauseam). We also have a bunch of USB chargers, each of which has a single USB port on it. I'd like to have something permanently connected to AC power with at least 4 USB ports on it, so we can just plug devices in and don't need to go looking for a free outlet. So here's the question: if I buy a powered USB hub, will that do the job even if I don't connect it to a PC? Ideally if you have a hub that you can personally verify will be suitable, let me know the manufacturer and model :-) Thanks in advance! EDIT: The solution I eventually went for was this: Kensington 4-Port USB Charger for Mobile Devices (Europe) There's also a US version here: Kensington 4-Port USB Charger for Mobile Devices (USA) It arrived yesterday, so I used it to charge the following devices, all at the same time, overnight last night: 32GB iPhone 3GS 16GB iPhone 3G First-generation iPod Touch Kensington Portable Power Pack for Mobile Devices I can't say anything about the charging speed (as I left it overnight) but all devices were fully charged this morning.

• How intrusive is using VPN?

  - by Slade

  My company lets us work from home sometimes using VPN (during weather emergencies and stuff). When logging in a big window comes up that says the network is private and for employees only and that there's no right to privacy while using VPN. It makes sense that they don't want people poking around their network but I wonder if the company can use the connection to look around my computer while I'm connected. I'm not entirely computer-illiterate but I'm not a networks person at all so the technical documents I've found don't help me. Is that possible, and if so to what degree? UPDATE Thanks Mark. The funneling thing is what I was really asking about. Mostly I was worried that I would already have some IM conversation open or log into eBay forgetting that the VPN was open and that my company IT people would see it or that they would log my eBay password. Thanks again. ANOTHER UPDATE What if my son wants to play online poker or Warcraft etcetera while I have VPN on to work? Can my company think I'm the one playing if I am not typing often?

• Basic connectivity issues between Win 7 and XP mixed wired/wireless network. [Solved]

  - by Pulse

  Setup: Windows 7 x64 Ultimate desktop hard wired to Asus WL500gp router (WL500gpv2-1.9.2.7-d-r1445 firmware) Several Bridged VirtualBox VM's running XP, 7, ubuntu server 10.04, Mint 9 and SuSE 11.2 Win XP Pro SP3 notebook with D-Link Airplus wireless network card. No firewall or other security software currently running on either platform (at least for the duration of the test) Situation: Router is acting DHCP server Clients are receiving correct addresses and additional parameters Internet connectivity is available from all clients Windows 7 sharing is set to Network type = work (not home group) NetBT is disabled on all clients using smb over TCP What I can do: I can ping the router and internet addresses from the wireless XP notebook I can ping the Win 7 desktop and any VM from the XP wireless notebook I can ping all devices from the router All VM's and 7 can ping each other and the router as well as Internet addresses What I can't do: I cannot ping the XP wireless notebook from either the Win 7 desktop or the VM's; it always returns a destination host unreachable error. Tracert resolves the name or the XP notebook but also returns a destination host unreachable. From the above it would seem that something is blocking connectivity in a single direction (from the Win 7 box to the Win XP notebook) only but the router can ping the XP notebook. Some fresh input would be most welcome, as this is beginning to drive me batty. Thanks

• Mounting fuse sshfs fails when invoked by Cron on FreeBSD 9.0

  - by Tal

  I have a remote server filesystem that I'm attempting to mount locally on a FreeBSD 9 machine via FUSE sshfs, and Cron for a backup routine. I have ssh keys between the boxes setup to allow for passwordless login as the root user on the local machine. Cron is set to run the following script (in Root's crontab): #!/bin/sh echo "Mounting Share" /usr/local/bin/sshfs -C -o reconnect -o idmap=user -o workaround=all <remote user>@<remote domain>.com: /mnt/remote_server As root, I can run this script on the command line without issue, and without being asked for a password the share mounts successfully. Yet, when run by Cron the script fails. The path to sshfs is identical to the value of which sshfs Here is the email root receives from the Cron Daemon: X-Cron-Env: <SHELL=/bin/sh> X-Cron-Env: <HOME=/root> X-Cron-Env: <PATH=/usr/bin:/bin> X-Cron-Env: <LOGNAME=root> X-Cron-Env: <USER=root> Mounting Share fuse: failed to exec mount program: No such file or directory fuse: failed to mount file system: No such file or directory I'm stumped as to why I'm receiving No such file or directory in this instance. It further seems odd given that the paths appear to be correct. I've also attempted to compare the output of env on the shell with env inserted into the script. I don't see any environment variables that should cause this trouble. At bootup, FUSE reports its version as: fuse4bsd: version 0.3.9-pre1, FUSE ABI 7.8 Help me ServerFault wizards, you're my only hope!

• backup an existing linux server to a virtualbox virtual machine

  - by user146526

  I have some servers and VPSs to many companies across the world. I want to back them up locally. I have some backup solutions enabled to remote hosts, but I want to have a local backup on a computer at home. What I am thinking is: 1) Create a virtualbox virtual machine, install the same version linux as the server. 2) Use rsync to backup the server to the local virtualbox machine. (something like rsync -av --delete --progress --exclude '/dev/' --exclude '/proc/' root@server_ip:// / ) 3) Repeat the command every few days update files. 4) In case of a hard disk failure, or any other bad event, reverse the rsync command and get the files back and continue my bussiness. I tried it with 2 openvz VPS, the one was a backup of the other. I also tried to transfer normal linux server host to openvz machine and it worked great. That way looks pretty clean and easy to me, this is the kind of solution I am looking for. However I need to be sure that this will work if I am going to do it. The question is, will that work ok ? Does anyone see any problem with that ? Do you have any other suggestions ? Thanks

• Hyper-V and attaching physical disks

  - by Mike Christiansen

  So, I'm looking at rebuilding my home server. My current setup is the following Windows 7 Ultimate 1TB Boot Drive (my smallest drive) Windows Dynamic Spanned volume, continaing 1x 1TB drive, 2x 2TB drives, totalling 5TB. I am upgrading to a hardware RAID controller, and I would like to run Hyper-V server core. However, I want to retain the ability to join my "file server" to a homegroup, so I must use Windows 7. I know VHDs can only be like 127GB or something, so I obviously need to directly connect disks to my Windows 7 machine. Here is my plan: Server Core 2008 R2 (Hyper-V) 1TB Boot Drive (storing VHDs for boot drives of VMs) - possibly in a RAID 1 with my other 1TB drive 5x 2TB drives (1x 2TB drive hot spare), totalling 10TB, directly attached to a Windows 7 VM, for use of homegroup for this array. In the past, I directly attached the windows dynamic volume to a Windows 7 VM, and performance was abysmal. The question is, with hardware RAID, will it really make that much of a difference? Server specs: Intel Core 2 Quad Q9550 2.83GHz Asus Maximus II Formula (PCI-E x16) 8GB DDR2 RAM PC2-6400 (Yes, I know its a bit out of date)

• htaccess hacked - i've deleted code and file - what next?

  - by user1762595

  My website was hacked recently. I think i've found the code that was added to the htaccess file, deleted it and then added script to prevent the htaccess file being accessed again. I've also deleted the php file that the hacked code refers to (common.php). What do i need to do next? I'm not a programmer or website developer but i really wanted to see if i could fix the problem myself as i've spent quite a few hours trying and don't give up easily. Here is the hacked code that i deleted; <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{HTTP_USER_AGENT} (google|yahoo) [OR] RewriteCond %{HTTP_REFERER} (google|yahoo) RewriteCond %{REQUEST_URI} /$ [OR] RewriteCond %{REQUEST_FILENAME} (shtml|html|htm|php|xml|phtml|asp|aspx)$ [NC] RewriteCond %{REQUEST_FILENAME} !common.php RewriteCond /home/httpd/vhosts/bluestardive.com/httpdocs/common.php -f RewriteRule ^.*$ /common.php [L] </IfModule> this code has to stay in the htaccess file as it redirects my url to seo friendly ones or the website errors, but has this code been hacked as well? # Apache search queries statistic module RewriteEngine On AddHandler php5-fastcgi .php .php5 # <contrexx> # <core_modules__alias> RewriteRule ^about-us$ /index.php?page=883 [L,NC] RewriteRule ^ausfluge-und-aktivitaten$ /index.php?page=800 [L,NC] RewriteRule ^bluestardive-news$ /index.php?page=919 [L,NC] RewriteRule ^bookings$ /index.php?page=911 [L,NC] RewriteRule ^diveresort$ /index.php?page=879 [L,NC] RewriteRule ^diving$ /index.php?page=880 [L,NC] RewriteRule ^excursions-and-activities$ /index.php?page=881 [L,NC] RewriteRule ^galerie$ /index.php?section=gallery [L,NC] RewriteRule ^oceannight$ http://www.bluestardive.com/index.php?page=906 [L,NC] RewriteRule ^philosophy$ /index.php?page=846 [L,NC] RewriteRule ^reservation$ /index.php?page=917 [L,NC] RewriteRule ^reservierung$ /index.php?page=918 [L,NC] RewriteRule ^resort$ /index.php?page=798 [L,NC] # </core_modules__alias> # </contrexx> many thanks for any help Claire

  - by ant2009

  Hello HP Mini 210 I am trying to install windows starter 7. Currently I have installed fedora 14 xfce. And I have allocated 24 GB NTFS for hard disk for the windows partition. My current partitions are as follows: /dev/sda2 97G 4.9G 91G 6% / tmpfs 494M 92K 494M 1% /dev/shm /dev/sda1 485M 68M 392M 15% /boot /dev/sda5 169G 26G 135G 16% /home I have created a boot USD to install windows starter 7. When the computer boots into the windows setup and I selected the partition I want to install windows on. I get the following message: "Setup was unable to create a new system partition or locate an existing system partition." This is setup displaying all my partitions: Disk 0 Partition 1 500MB 0 Primary Disk 0 Partition 2 97.7GB 0 Primary Disk 0 Partition 3 4GB 0 Primary Disk 0 Partition 4 171.3GB 0 Logical Disk 0 Partition 5 24.6GB 24.5 Logical <-- Trying install on this partition NTFS I have also tried to delete the partition in setup and create a new one. And also tried to format the partition. However, I still get the same error message. Many thanks for any advice,

• FTP account ownership on vhost directory makes Apache not run website correctly

  - by CodeShining

  I've purchased a virtual server, where I'm given of a non-root sudo-enabled user. Actually I do need to create an FTP account that's not that sudo-able account, so I created a no-login account just for that purpose. I've set up VSFTPd correctly, also enabling the "userlist" feature, to specify which user are permitted to use FTP. Then I created an empty directory under my sudo-able account, and I gave ownership permissions to the second account, so to make it more easy to understand, let's say the main account (the one I do use to manage my VPS) is called ubuntu and the FTP-user is named ftpuser, I created a directory /home/ubuntu/mywebsite giving the ownership to ftpuser:ftpuser. Then I uploaded a worpdress website, whose default permissions are 755 and 644. The issue is that Apache is not given of any privilege to run the website. How can I make the website run properly, and which is the most secure? Should I run that virtualhost with another user (if it's possible)? Should I force the FTP user to use the www-data group (if that's possible) and run with permissions like 775 and 664? How can I solve this issue? Any help is appreciated, I'd like to run it using the default permissions, so any update won't break up anything (because of permissions reset).

• Troubleshooting my internet connection

  - by Simon Verbeke

  While I was out of the house, my father rearranged the network cables a bit. I don't know what he has done exactly - He says nothing more then pulling and untangling. When I came back home, my internet connection changed its IP from 192.168.0.205 to 169.254.197.233. The speed changed from 1Gbps to 10Mbps. It has also been at 100Mbps for a while. My subnetmask changed from 255.255.255.0 to 255.255.0.0. The standard gateway changed from 192.168.0.1 to no standard gateway. My DNS servers remain the same. I have checked the lights of the UTP ports, and it looks like it's only sending a heartbeat every few seconds. A sketch of the (relevant part of) the network: My PC ----- extender ----- modem ^ ^ ^ Wired | Wired | This thing connects two cables to each other All the cabling is gigabit, my network card is a Realtek RTL8168C(P)/8111(P) Family PCI-E Gigabit Ethernet NIC (NDIS 6.20). THe modem is a CBN SVG6540E I have no idea what is going on here and I don't know how to find out either. Any help is welcome! If you need any more info, please ask.

• Cloning a failing disk (Win 7)

  - by daveh551

  I have a Windows 7 machine with several partitions on a 1.5T drive. Windows has been complaining about disk errors and imminent failure, so I have purchased a new 2TB drive. The failing disk has not completely failed, and, in fact, I was able to boot Windows from it (after a couple tries) and examine the SMART logs - the only RED item was 1 sector being reallocated. But when I try to Clone it to the new Drive using Acronis True Image Home (2010), True Image can see the drive, the partitions, and the contents, but when it goes to actually do the clone, it says "Failed to move. Make sure the destination disk is not smaller than the source disk, and that there are not errors on the disk" (or something like that). What are some other options for simply cloning the failing drive. I'd like to clone the entire disk, but am willing to do it partition by partition if necessary. Was this a known failing of the 2010 edition of ATI, or is it really something hosed in my system. Would upgrading to the 2012 edition be likely to work any better? (I'd download the trial and try it out, but if I remember right, the cloning operation is disabled in the trial version), and I don't have enough free disk space to make an entire image.) What are some other cloning software packages if ATI won't work? Note that I'm only looking to clone the disk, not make an image as a back up - I use Ghost for that, and can fall back to that if I have to. It looks to me like CloneZilla would do the job. Any recommendations? Thanks, and if this duplicates other questions, I apologize.

• One workstation gets slow access to the server, but others are fast

  - by Mike Hanson

  I've just setup a machine with Windows Server 2008. It hosts various services, like IIS, POP3, SMTP, Music for Squeezeboxes, VNC. All was working well for the first week or so. One day I needed to create a mapped drive on the server, so it could access files on my workstation. Windows indicated that Network Discovery was needed, so I turned it on with the "Home / Office" option (rather than "Public"). This may be coincidence, but since that time I've been having troubles accessing various services from my main workstation (running Windows 7/64): POP3 continued working correctly, but SMTP was delayed or failed entirely. (Telnet took 20 seconds to connect, but Outlook would never send messages.) VNC failed entirely. I reinstalled it on the server, and now it works but feels sluggish. The music web server was extremely delayed and usually failed. I tried reinstalling, and now it takes about 30 seconds to show the page name on the browser tab, and another 30 seconds to display any page contents. Other machines on the local network seem fine, as do machines connected via the Internet. I don't believe I changed anything on my own machine that would cause this. I considered the possibility that my anti-virus was involved, so I uninstalled AVG (commercial version), but that didn't help. I installed Norton 360 after that, and it didn't complain of viruses on my machine, and the delays remained. Because only my machine is affect, I'm tempted to blame it, except that reinstalling software on the server improved the situation, so there is almost certainly something going on with the server too. The firewall has all the necessary ports open, and it works fine for the other workstations (including external machines connected via the Internet), which indicates that it should be OK. Any ideas?
