• pfsense peer-to-peer OpenVPN not connecting

  - by John P

  I'm trying to setup a peer-to-peer OpenVPN between two pfsense servers running 2.0.1-RELEASE, but the client keeps getting the connection dropped, with a status of "reconnecting; ping-restart" and nothing appears to be routing between them.

• Using Supermicro IPMI behind a Proxy?

  - by Stefan Lasiewski

  This is a SuperMicro server with a X8DT3 motherboard which contains an On-board IPMI BMC. In this case, the BMC is a Winbond WPCM450). I believe many Dell servers use this a similar BMC model. A common practice with IPMI is to isolated it to a private, non-routable network. In our case all IPMI cards are plugged into a private management LAN at 192.168.1.0/24 which has no route to the outside world. If I plug my laptop into the 192.168.1.0/24 network, I can verify that all IPMI features work as expected, including the remote console. I need to access all of the IPMI features from a different network, over some sort of encrypted connection. I tried SSH port forwarding. This works fine for a few servers, however, we have close to 100 of these servers and maintaining a SSH client configuration to forward 6 ports on 100 servers is impractical. So I thought I would try a SOCKS proxy. This works, but it seems that the Remote Console application does not obey my systemwide proxy settings. I setup a SOCKS proxy. Verbose logging allows me to see network activity, and if ports are being forwarded. ssh -v -D 3333 [email protected] I configure my system to use the SOCKS proxy. I confirm that Java is using the SOCKS proxy settings. The SOCKS proxy is working. I connect to the BMC at http://192.168.1.100/ using my webbrowser. I can log in, view the Server Health, power the machine on or off, etc. Since SSH verbose logging is enabled, I can see the progress. Here's where it get's tricky: I click on the "Launch Console" button which downloads a file called jviewer.jnlp. JNLP files are opened with Java Web Start. A Java window opens. The titlebar says says "Redirection Viewer" in the title bar. There are menus for "Video" "Keyboard" "Mouse", etc. This confirms that Java is able to download the application through the proxy, and start the application. 60 seconds later, the application times out and simply says "Error opening video socket". Here's a screenshot. If this worked, I would see a VNC-style window. My SSH logs show no connection attempts to ports 5900/5901. This suggests that the Java application started the VNC application, but that the VNC application ignores the systemwide proxy settings and is thus unable to connect to the remote host. Java seems to obey my systemwide proxy settings, but this VNC application seems to ignore it. Is there any way for me to force this VNC application to use my systemwide proxy settings?

• How to set up Mod_WSGI for Python on Ubuntu

  - by AutomatedTester

  Hi, I am trying to setup MOD_WSGI on my Ubuntu box. I have found steps that said I needed to do the following steps I found at http://ubuntuforums.org/showthread.php?t=833766 sudo apt-get install libapache2-mod-wsgi sudo a2enmod mod-wsgi sudo /etc/init.d/apache2 restart sudo gedit /etc/apache2/sites-available/default and update the Directory <Directory /var/www/> Options Indexes FollowSymLinks MultiViews ExecCGI AddHandler cgi-script .cgi AddHandler wsgi-script .wsgi AllowOverride None Order allow,deny allow from all </Directory> sudo /etc/init.d/apache2 restart Created test.wsgi with def application(environ, start_response): status = '200 OK' output = 'Hello World!' response_headers = [('Content-type', 'text/plain'), ('Content-Length', str(len(output)))] start_response(status, response_headers) return [output] Step 2 fails because it says it can't find mod-wsgi even though the apt-get found it. If I carry on with the steps the python app just shows as plain text in a browser. Any ideas what I have done wrong?

• Fedora 12 Wireless problems (Intel Wireless 4965AGN Card)

  - by Ninefingers

  Hi All, I'm having an interesting experience with my wireless card at the moment. Basically, it does like this: I connect to the local wireless network (netgear router) It works, briefly, allowing me to browse a webpage or maybe two, if I'm lucky. It then stops working / sending any packets, whilst reported still connected. Now, me being me I've had a look to see what I can find. wpa_supplicant.log looks like this: Trying to associate with valid_mac:a2:30 (SSID='vennardwireless' freq=2462 MHz) Associated with valid_mac:a2:30 WPA: Key negotiation completed with valid_mac:a2:30 [PTK=CCMP GTK=TKIP] CTRL-EVENT-CONNECTED - Connection to valid_mac:a2:30 completed (reauth) [id=0 id_str=] CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys So that's working fine. dmesg | grep "*iwl*" spits out this: iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, 1.3.27kds iwlagn: Copyright(c) 2003-2009 Intel Corporation iwlagn 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 iwlagn 0000:03:00.0: setting latency timer to 64 iwlagn 0000:03:00.0: Detected Intel Wireless WiFi Link 4965AGN REV=0x4 iwlagn 0000:03:00.0: Tunable channels: 13 802.11bg, 19 802.11a channels iwlagn 0000:03:00.0: irq 32 for MSI/MSI-X phy0: Selected rate control algorithm 'iwl-agn-rs' iwlagn 0000:03:00.0: firmware: requesting iwlwifi-4965-2.ucode iwlagn 0000:03:00.0: loaded firmware version 228.61.2.24 Registered led device: iwl-phy0::radio Registered led device: iwl-phy0::assoc Registered led device: iwl-phy0::RX Registered led device: iwl-phy0::TX iwlagn 0000:03:00.0: iwl_tx_agg_start on ra = 00:24:b2:32:a3:30 tid = 0 iwlagn 0000:03:00.0: iwl_tx_agg_start on ra = 00:24:b2:32:a3:30 tid = 0 So that's working too. I can also ping 192.168.0.1 -I wlan0 and arping 192.168.0.1 -I wlan0 the router until the network falls over. uname -r:2.6.32.10-90.fc12.x86_64. Laptop is a Core2 Duo (2Ghz) with 3GB RAM. Other symptoms I've noticed are that wireshark freezes when I capture on the "broken" interface until I disconnect. Am using networkmanager as per normal. Stupidly, I can connect to the same router via eth0/a cat6 cable just fine. Everyone else can connect to the AP fine (from Windows). Yes, I'm sat right next to it and not trying to access a hotspot the other side of the world. Any ideas? Is this a broken update? (I intend to reboot and test an older kernel later)? Anyone else come across this? Edit: iwconfig wlan0 rate auto is the settings I'm using for rates. Also, according to networkmanager the network is still connected. Thanks for any pointers / advice.

• How to start networking on a wired interface before logon in Ubuntu Desktop Edition

  - by Burly

  Problem Ubuntu 9.10 Desktop Edition (and possibly previous versions as well, I haven't tested them) has no network connections after boot until at least 1 user logs in. This means any services that require networking (e.g. openssh-server) are not available until someone logs in locally either via gdm, kdm, or a TTY. Background Ubuntu 9.10 Desktop Edition uses the NetworkManager service to take commands from the nm-applet in Gnome (or it's equivalent in KDE). As I understand it, while NetworkManager is running at boot, it is not issued any commands to connect until you login for the first time because nm-applet isn't running until you login and your Gnome session starts (or similar for KDE). I'm not sure what prompts NetworkManager to connect to the network when you login via a TTY. There are several relevant variables involved in starting up the network connections including: Wired vs Wireless (and the resulting drivers, SSID, passwords, and priorities) Static vs DHCP Multiple interfaces Constraints Support Ubuntu 9.10 Karmic Koala (bonus points for additional supported versions) Support wired eth0 interface Receive an IP address via DHCP Receive DNS information via DHCP (obviously the DHCP server must provide this information) Enable networking at the proper time (e.g. some time after file systems are loaded but before network services like ssh start) Switching distros or versions (e.g. to Server Edition) is not an acceptable solution Switching to a Static IP configuration is not an acceptable solution Question How to start networking on a wired interface before logon in Ubuntu Desktop Edition? What I have tried Per this guide, adding the following entry into /etc/network/interfaces so that NetworkManager won't manage the eth0 interface: auth eth0 iface inet dhcp After reboot eth0 is down. Issuing ifconfig eth0 up brings the interface up but it receives no IP address. Issuing dhclient eth0 instead Does bring up the interface and it Does receive an IP address. Completely removing the NetworkManager package in addition to the settings above. I'm a bit confused with the whole UpStart/SysVinit mangling that's going in Ubuntu currently (I'm more familiar with the CentOS world). However, directly issuing sudo /etc/init.d/networking start Or sudo start networking does not bring up the eth0 interface at all, much less get an IP address.

• Partitioning recommendations for a Proxmox VM Server (OpenVZ)

  - by luison

  We are new to virtualization and we are planning to turn our online server into a virualized one, mainly for maintenance, backup and recovery improvements. Initially we would only have one real virtual system with load plus 1-3 copys for testing and recovering and maybe a small centralized syslog virtual machine. We would like, if possible the host machine to include an iptables plus rsync to back up to other machines and some other global security systems. Due to this and the offerings of our hosting supplier we are mainly considering Proxmox for its simplicity (we like the idea of its web admin panel) and as I also understand that the container approach of OpenVMZ systems may fit well resource wise with our setup. The base system comes with debian so we can personalise it to our requirements. Proxmox installations default installs an LVM partition for the VMs. Our doubts are with the fact of what would be the best partition structure for this considering that: we would like to have a mirror of the root partition we could boot from if required (our provider supports booting the system from another partition via control panel) we ideally would like to have a partition that could be shared among the VM systems. We still don't know if this is possible directly with OpenVMZ containers, otherwise we are considering doing this by sharing it via NFS on the host machine. we want to use the backup system available on the proxmox host administrator to programme VMs backups and then rsync it to another machine. With this based on a Linux Raid of aprox (750Gb) we are considering something like: ext3_1/ - (20Gb) ext3_2/bak_root - (20Gb) mostly unmounted, root partition sync LVM_1 /var/lib/vz - (390Gb) partition for virtual images LVM_2 /shared_data - (30Gb) LVM_3 /backups - (300Gb) where all backups would be allocated Our initial tests with Proxmox seem to have issues with snapshots backups like this, perhaps caused by the fact that they can not be done to another LVM partition (error: command 'lvcreate --size 1024M --snapshot --name vzsnap-ns204084.XXX.net-0 /dev/pve/LV' failed with exit code 5) in which case we might have to use a standart ext3 partition (but unsure if we can do this with the 4 primary partition limitations). Does this makes more or less sense? Would it be mad to for example write VMs /var/logs to a NFS mounted partition (on the host system)? Are their any other easier ways to mount host system partitions (or folders) to the VMs?

• Too many Tunnel Adapter Interfaces

  - by Tomas Lycken

  If I open a command prompt on my machine and type ipconfig /all, I see lots of Tunnel adapter Local Area Connection* 9: Media state . . . . . . . . . . . . . : Media disconnected Connection-specific DNS Sufficx . . . : Description . . . . . . . . . . . . . : Microsoft 6to4 Adapter #5 Physical address. . . . . . . . . . . : 00-00-00-00-00-00-00-E0 DHCP Enabled. . . . . . . . . . . . . : No Autoconfiguration Enabled . . . . . . : Yes In fact, they're so many that my "real" adapters are pushed out of the stack, and can't be seen anymore. Is there any flag I can use on ipconfig to hide all virtual interfaces? Or is there some other way around this problem? Since they always say "Media disconnected" I suppose disabling could be an option, but if possible I'd rather not turn any functionality off. I just want to control what output I get from ipconfig. Also, I know these are related to IPv6 stuff. However, most of what I find on google merely states what these are, and that they're harmless - nothing about hiding/removing them.

• IIS 7.5 Error 1007

  - by darkdog

  I have a Windows 2008 R2 Virtual Server. I removed the "Default Web Site" using IIS Manager and now all my other sites now report an error saying they can't access the site (or something similar). I thought I could just remove the role, re-install IIS again and start with a clean slate. After I re-installed IIS it's now reporting the following error in the event log: The World Wide Web Publishing Service (WWW service) failed to register the URL prefix of "http://www.mash-guild.com:80:192.168.245.132/" for the website of "4".

• Installing gnome on Linode with Ubuntu 9.10 x64 - remote VNC/RDP

  - by Kieran Benton

  Hi, I'm a self confessed Linux newbie, having lived and worked mostly within the Windows world for most of my life. I'm making the effort to try moving my virtual host from a Windows box to a Linode instance to try and better learn Linux, and one of the uses I occasionally have with my current Windows VPS is to RDP into it and browse the internet. I'm aware that this is probably not best practice (from either performance or security), and most of the time I will be learning from the shell, but I do occasionally need to boot into a GUI. Because of this, I'd like the ability within my Ubuntu installation on Linode to start/stop Windows X and Gnome at will after SSHing in (startx? gdm?), so I've tried: apt-get install ubuntu-desktop Reboot startx But I've got an error that no amount of googling has helped me with so far, which I'm assuming is something to do with the fact the box is headless and X needs some more configuration that is beyond me at the moment: root@local:~# startx hostname: Unknown host xauth: creating new authority file /root/.Xauthority xauth: creating new authority file /root/.Xauthority xauth: (argv):1: bad display name "local.kieranbenton.com:0" in "list" command xauth: (stdin):1: bad display name "local.kieranbenton.com:0" in "add" command X.Org X Server 1.6.4 Release Date: 2009-9-27 X Protocol Version 11, Revision 0 Build Operating System: Linux 2.6.24-23-server x86_64 Ubuntu Current Operating System: Linux local.kieranbenton.com 2.6.31.5-x86_64-linode9 #1 SMP Mon Oct 26 19:35:25 UTC 2009 x86_64 Kernel command line: root=/dev/xvda xencons=tty console=tty1 console=hvc0 nosep nodevfs ramdisk_size=32768 ro Build Date: 26 October 2009 05:19:56PM xorg-server 2:1.6.4-2ubuntu4 (buildd@) Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.

• Ubuntu suddenly freezes

  - by tapan

  I've a strange problem with my ubuntu 10.04 installation. Whenever i boot into ubuntu the entire system freezes / hangs soon after (~ 2 mins in). This problem exists on my windows 7 installation too. However if i start World of Warcraft or Warcraft on windows it doesnt hang for the duration i'm playing the game. After i stop playing and exit the game my laptop hangs inside 2 mins. Here is when it gets weirder. If i disconnect the charger, the laptop doesn't hang. However when I start it in ubuntu recovery mode and drop to root shell and use the 'startx' command everything works perfectly. I cannot figure out what the problem is. i have an intel core2duo 2.2ghz processor, intel mobile 965 graphics, 2 GB RAM for more details here is the output of cat /proc/cpuinfo : processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz stepping : 11 cpu MHz : 2201.000 cache size : 4096 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc arch_perfmon pebs bts pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm lahf_lm ida tpr_shadow vnmi flexpriority bogomips : 4389.80 clflush size : 64 power management: processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz stepping : 11 cpu MHz : 2201.000 cache size : 4096 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 apicid : 1 initial apicid : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc arch_perfmon pebs bts pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm lahf_lm ida tpr_shadow vnmi flexpriority bogomips : 4388.96 clflush size : 64 power management: here is the output of cat /proc/meminfo MemTotal: 2052440 kB MemFree: 55924 kB Buffers: 579352 kB Cached: 821752 kB SwapCached: 704 kB Active: 897124 kB Inactive: 1032256 kB Active(anon): 412140 kB Inactive(anon): 264804 kB Active(file): 484984 kB Inactive(file): 767452 kB Unevictable: 0 kB Mlocked: 0 kB HighTotal: 1178440 kB HighFree: 6012 kB LowTotal: 874000 kB LowFree: 49912 kB SwapTotal: 995988 kB SwapFree: 986616 kB Dirty: 8928 kB Writeback: 0 kB AnonPages: 527596 kB Mapped: 76536 kB Slab: 39480 kB SReclaimable: 21100 kB SUnreclaim: 18380 kB PageTables: 5672 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 2022208 kB Committed_AS: 1856400 kB VmallocTotal: 122880 kB VmallocUsed: 11928 kB VmallocChunk: 104644 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 4096 kB DirectMap4k: 16376 kB DirectMap4M: 892928 kB Also the kern.log doesn't show any errors.

• What is the difference between Anycast and GeoDNS / GeoIP wrt HA?

  - by Riyad

  Based on the Wikipedia description of Anycast, it includes both the distribution of a domain-name-to-many-IP-mapping across many DNS servers as well as replying to clients with the most geographically close (or fastest) server. In the context of a globally distributed, highly available site like google.com (or any CDN service with many global edge locations) this sounds like the two key features one would need. DNS services like Amazon's Route53, EasyDNS and DNSMadeEasy all advertise themselves as Anycast-enabled networks. Therefore my assumption is that each of these DNS services transparently offer me those two killer features: multi-IP-to-domain mapping AND routing clients to the closest node. However, each of these services seem to separate out these two functionalities, referring to the 2nd one (routing clients to closest node) as "GeoDNS", "GeoIP" or "Global Traffic Director" and charge extra for the service. If a core tenant of an Anycast-capable system is to already do this, why is this functionality being earmarked as this extra feature? What is this "GeoDNS" feature doing that a standard Anycast DNS service won't do (according to the definition of Anycast from Wikipedia -- I understand what is being advertised, just not why it isn't implied already). I get extra-confused when a DNS service like Route53 that doesn't support this nebulous "GeoDNS" feature lists functionality like: Fast – Using a global anycast network of DNS servers around the world, Route 53 is designed to automatically route your users to the optimal location depending on network conditions. As a result, the service offers low query latency for your end users, as well as low update latency for your DNS record management needs. ... which sounds exactly like what GeoDNS is intended to do, but geographically directing clients is something they explicitly don't support it yet. Ultimately I am looking for the two following features from a DNS provider: Map multiple IP addresses to a single domain name (like google.com, amazon.com, etc. does) Utilize a DNS service that will respond to client requests for that domain with the IP address of the nearest server to the requestee. As mentioned, it seems like this is all part of an "Anycast" DNS service (all of which these services are), but the features and marketing I see from them suggest otherwise, making me think I need to learn a bit more about how DNS works before making a deployment choice. Thanks in advance for any clarifications.

• mount_afp on linux, user rights

  - by Antonio Sesto

  I need to mount a remote filesystem on a linux box using the afp protocol. The linux box runs an old Debian 4. I downloaded the source code of mount_afp, compiled it and installed it with all the required packages. Then created /etc/fuse with the following command: mknod /dev/fuse c 10 229 (according to the instructions here) I can mount the remote filesystem as root by executing: mount_afp afp://USER:PASSWD@REMOTE_SERVER/FOLDER /mnt/MOUNTPOINT/ but the same command fails when run as normal user (of the local machine). After reading here and there, I created a group fuse, and added my normal user U to the group fuse: [prompt] groups U U fuse Then modified the group of /dev/fuse, that now has the following rights: 0 crwxrwx--- 1 root fuse 10, 229 Feb 8 15:33 /dev/fuse However, if the user U tries to mount the remote filesystem by using the same command as above, U gets the following error: Incorrect permissions on /dev/fuse, mode of device is 20770, uid/gid is 0/1007. But your effective uid/gid is 1004/1004 But the user U with uid 1004 has also gid 1007 (group fuse). I might think the problem is related to real/effective/etc. ID, but I do not know how to proceed and could not find any clear instructions. Could you please help me? There is also another problem. If I mount /mnt/MOUNTPOINT as root and run ls -l /mnt, I get: drwxrwxrwx 15 root root 466 Feb 8 16:34 MONTPOINT If I run ls -l /mnt as normal user U I get: ? ?????????? ? ? ? ? ? MOUNTPOINT in fact when I try to cd /mnt/MOUNTPOINT I get: $-> cd /mnt/MOUNTPOINT -sh: cd: /mnt/MOUNTPOINT: Not a directory Then I unmount /mnt/MOUNTPOINT as root and run again ls -l /mnt as normal user U I get: 0 drwxr-xr-x 2 root root 6 Feb 8 15:32 MOUNTPOINT/ After reading Frank's answer, I killed every shell/process running with privileges of user U. Still U cannot mount the remote filesystem, but the error message has changed. Now it is: "Login error: Authentication failed". The problem is not related to remote login/password since the same command works perfectly when run as root of the local machine. Since I cannot get mount_afp to work with normal users, I decided to follow mgorven's suggestion. So I run the commands: mount_afp -o allow_other afp://USER:PASSWD@REMOTE_SERVER/FOLDER /mnt/MOUNTPOINT/ and mount_afp -o user=U afp://USER:PASSWD@REMOTE_SERVER/FOLDER /mnt/MOUNTPOINT/ The mount succeeds but user U cannot access the mount point. If U executes ls -l in /mnt U@LOCAL_HOST [/mnt] $-> ls -l ls: cannot access MOUNT_POINT: Permission denied total 0 ? ?????????? ? ? ? ? ? MOUNT_POINT Is it so hard to have this utility working?

• Ubuntu/Windows suddenly freezes

  - by tapan

  I've a strange problem with my ubuntu 10.04 installation. Whenever i boot into ubuntu the entire system freezes / hangs soon after (~ 2 mins in). This problem exists on my windows 7 installation too. However if i start World of Warcraft or Warcraft on windows it doesnt hang for the duration i'm playing the game. After i stop playing and exit the game my laptop hangs inside 2 mins. Here is when it gets weirder. If i disconnect the charger, the laptop doesn't hang. However when I start it in ubuntu recovery mode and drop to root shell and use the 'startx' command everything works perfectly. I cannot figure out what the problem is. i have an intel core2duo 2.2ghz processor, intel mobile 965 graphics, 2 GB RAM for more details here is the output of cat /proc/cpuinfo : processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz stepping : 11 cpu MHz : 2201.000 cache size : 4096 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc arch_perfmon pebs bts pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm lahf_lm ida tpr_shadow vnmi flexpriority bogomips : 4389.80 clflush size : 64 power management: processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz stepping : 11 cpu MHz : 2201.000 cache size : 4096 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 apicid : 1 initial apicid : 1 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc arch_perfmon pebs bts pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm lahf_lm ida tpr_shadow vnmi flexpriority bogomips : 4388.96 clflush size : 64 power management: here is the output of cat /proc/meminfo MemTotal: 2052440 kB MemFree: 55924 kB Buffers: 579352 kB Cached: 821752 kB SwapCached: 704 kB Active: 897124 kB Inactive: 1032256 kB Active(anon): 412140 kB Inactive(anon): 264804 kB Active(file): 484984 kB Inactive(file): 767452 kB Unevictable: 0 kB Mlocked: 0 kB HighTotal: 1178440 kB HighFree: 6012 kB LowTotal: 874000 kB LowFree: 49912 kB SwapTotal: 995988 kB SwapFree: 986616 kB Dirty: 8928 kB Writeback: 0 kB AnonPages: 527596 kB Mapped: 76536 kB Slab: 39480 kB SReclaimable: 21100 kB SUnreclaim: 18380 kB PageTables: 5672 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 2022208 kB Committed_AS: 1856400 kB VmallocTotal: 122880 kB VmallocUsed: 11928 kB VmallocChunk: 104644 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 4096 kB DirectMap4k: 16376 kB DirectMap4M: 892928 kB Also the kern.log doesn't show any errors.

• Business Owners - What Remote Desktop Solution Do You Use To Service Your Clients PCs?

  - by Sootah

  Howdy fellow computer geeks, I am the owner of a local computer repair business that primarily services its clients on-site. On the occasions that we do service the machines in the office we generally have one of our techs pick the computer up while they are out and about and bring it back with them. Only rarely will we require the customer to bring us the computer themselves. In order to reduce costs, be much more efficient, and potentially expand our market far beyond what would be feasible with travel required; I am looking at ways that we can service our clients remotely whenever possible. What we're in need of is a solid remote desktop application that will be incredibly easy for our customers to connect to, as well as be robust enough that we don't need the client babysitting the computer during the entire repair. Ideally I would like to use a web-based solution so that we don't have to walk the customers through installing, connecting, and configuring it over the phone. This would be unacceptable because of the level of service they are used to. Effectively we'd want them to be able to just go to a URL, enter a PIN or something, and then they are connected and ready to rumble. (Obviously the option to just email them a link that'd do all this for them would be what we'd be aiming for) Along with the ease of use factor, we would need the product to not require any further intervention on the part of the client after we have connected. Nobody is going to be happy if we have to call them every 15 minutes so they can reconnect to us every time we reboot - so auto-reconnect is an absolute must. The only product I know of right now that does any of this is LogMeIn Rescue. It allows unattended access, the applet is lightweight and installs quickly, and the customer can either enter a PIN on the site or just click a link emailed to them in order to connect. The only real downside I see to LogMeIn Rescue is that it's $120.00/month per technician. While we'd ultimately end up saving far more than that per month just in fuel costs alone, I'd like to explore any other options out there that I may not have come across. So - Are there any equally good products out there? If so what are they, why do you recommend them, how have you been utilizing them yourself, and what do they cost? Thanks in advance for your help! -Sootah

• Dynamic DNS with Comcast

  - by colithium

  I've just recently moved across town. Previously, I had Dynamic DNS set up so I could remotely connect to my desktop (primarily to use TightVNC). My ISP was Comcast and I'm in the Denver, Colorado area. Currently, I'm still with Comcast and still in Denver. My router connects to the internet just fine and my Dynamic DNS record over at DynDNS did get updated with my router's current external IP address. So my router, DynDNS, and public DNS records all agree what my IP address is. However, I can't actually connect to anything from the outside world. My trace route to Google looks something like: Tracing route to google.com [74.125.19.147] 1 3 ms 1 ms 1 ms 192.168.1.1 (this is the internal IP address of my router) 2 * * * Request timed out. 3 9 ms 8 ms 10 ms te-8-2-ur02.wheatridge.co.denver.comcast.net [68.85.221.177] 4 12 ms 12 ms 19 ms te-0-8-0-2-ar02.aurora.co.denver.comcast.net [68.86.103.97] 5 16 ms 13 ms 11 ms pos-0-3-0-0-cr01.denver.co.ibone.comcast.net [68.86.91.1] 6 28 ms 28 ms 27 ms pos-0-9-0-0-cr01.dallas.tx.ibone.comcast.net [68.86.85.174] 7 29 ms 27 ms 28 ms pos-0-1-0-0-pe01.1950stemmons.tx.ibone.comcast.net [68.86.86.94] 8 66 ms 108 ms * 75.149.231.70 9 65 ms 68 ms 93 ms 72.14.233.77 10 67 ms 66 ms 66 ms 72.14.233.111 11 67 ms 67 ms 69 ms 216.239.43.144 12 68 ms 71 ms 73 ms 209.85.249.30 13 66 ms 66 ms 68 ms nuq04s01-in-f147.1e100.net [74.125.19.147] This is what the trace route looks like from an outside source to my DynDNS domain name: traceroute to 98.245.67.65 (98.245.67.65) 1 illuminati-130 138.67.130.61 2 138.67.63.253 138.67.63.253 3 vermiculite 138.67.253.20 4 csm-ct-gw 138.67.253.244 5 138.67.253.2 138.67.253.2 6 ge-7-24-ar01.denver.co.denver.comcast.net 68.86.128.17 7 te-0-4-0-0-ar02.denver.co.denver.comcast.net 68.86.179.21 8 te-9-3-ur01.wheatridge.co.denver.comcast.net 68.86.103.18 9 * * * {Times Out} Now my guess is, whatever is sitting just beyond my router (what the modem connects to) is gumming things up. Even though the routes aren't EXACTLY the same, that appears to be the spot that the trace route either stops or doesn't get a response. My question is, for Comcast networks (particularly in Denver), what would be the device that typically sits there? Is there anything I can do about it? That device seems to not respond to PING but does forward it along when I'm going outwards. But it looks like it eats it when the request is coming in. It's hard to prove that from these logs but I'm assuming that's the case because my router used to accept connections from the outside and I haven't changed anything on it.
