• Tcpreplaying using VMware

  - by Methos

  This is more like a testbed setup question. I want to use VMware to debug some networking code in the linux kernel in the VM. My VM has two network interfaces. What I want to do is replay the capture file in the host and receive the packets in the VM. My problem is I do not see replayed packets in the VM. I am running VMware and tcpreplay on the host as sudo. Hence I think there should not be any problem access devices files. I am running VMware workstation 7.0 a. I first began with Custom networking as that provides option of creating your own virtual network name. I wrote /dev/vmnet3 and /dev/vmnet4 for the two interfaces respectively. However, after booting the guest, I did not see any of these interfaces or devices files (in /dev) created on the host. b. Then I tried 'Host Only', but that does not show what bridge/device file is associated with the interface. c. Finally I tried bridged networking mode. I see vmnet1, vmnet8 and vboxnet0 on the host. I have tcpreplayed the capture file on each of these interfaces, for all the above three cases. I tried to capture packets in the VM using "tcpdump -i any". However, I do not see any packets. Any ideas/pointers?

• Load balanced IIS. Should I use NLB, or linux-based reverse proxy, or something else?

  - by growse

  What would be the best approach for load-balancing at least 2-3 Windows 2008 R2 IIS webservers running a multitude of .NET applications? My choices appear to be: 1) Hardware-based network device load balancer, like a Cisco CSS 2) Windows NLB 3) Some sort of linux based proxy, either haproxy or other The three servers sit as VMs on a vSphere farm, so I have the ability to clone to up the instance count in times of high load. I control the switch that the vSphere hosts are plugged into (Cisco 3750), but don't control the switching/routing infrastructure beyond that to the clients. (1) Is too expensive, and probably overkill for my needs. I've included this in case someone figures out a cunning way to do it on my existing network kit, which I doubt. (2) would seem to be the obvious "built-in" option, but seems to be quite fiddly messing around with network interfaces, multicast, and generally other things that seem to be needlessly complex. It's also fairly stupid, in that it can't remove hosts from the pool if they start throwing 500 errors or otherwise go wrong (3) is the most interesting option, as it would appear to offer the most flexibility and customizability, but without having to mess around with the network. However, while I'm familiar with the reverse-proxy capabilities of lighttpd etc, I'm not that well read on other options like HAProxy, which might be able to offer a lot more. Which would you go for, and is there anything I've not thought of?

• External USB HD with -optional- mains?

  - by Stephen

  Hi, I'm Christmas-present-buying, and I'd appreciate recommendations for a USB HD with an optional mains power input. I've hunted, but can't find all the information I want (partially due to sketchy product specifications). Background: This is for a digital TV which I do not own, and so I'd like to get it correct first time. The TV has a USB port to allow recording straight to disk, but the manuals don't say how much power can be drawn through the USB port. The manual's instructions state, possibly generically, to plug the drive in before connecting to the TV. Ideally I'd like a small (2.5"?) drive which can draw power over USB, with an mains power input if it turns out the USB port on the TV doesn't offer enough juice. The ideal is to use one cable, two max. A powered USB hub would introduce too much clutter. I've spotted that the LaCie Petit drives have what appears to be an additional power input, but I'm not even sure from the specs what that is. And the device doesn't ship with a mains adapter. Suggestions?

• MAMP Pro .xip.io, fixing urls with htaccess

  - by user3540018

  I've got all my websites set up with MAMP Pro. For instance, I got it set up, so when I go to example.com, the browser displays the website that's set up on my iMac. Now, I wanna get MAMP Pro to work so I can view my website on my other computers/devices (which are all hooked up on the same network.) So far all I had to do is check the checkbox "via Xip.io (LAN only)", and now I can view my website on my other computers/devices within my LAN by simply going to example.com.10.0.1.13.xip.io. Problem is, whenever I'm on this other computer/device, when I click on the links, I get 404 error. ie. whenever I go to example.com/news, I get the 404. But when I go to example.com.10.0.1.13.xip.io/news, THEN I get the right page. So in order to solve my problem I need to rewrite the urls. So whenever someone clicks on a link ie. goes straight to example.com/news, he'll go to example.com.10.0.1.13.xip.io/news. I don't want to change all the links in my MySQL file, but I believe I can do it simply with the htaccess file. I've opened the htaccess file and added the last two lines, but it just doesn't work. <IfModule mod_rewrite.c> RewriteEngine On # Send would-be 404 requests to Craft RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} !^/(favicon\.ico|apple-touch-icon.*\.png)$ [NC] RewriteRule (.+) index.php?p=$1 [QSA,L] RewriteCond %{HTTP_HOST} ^example\.com RewriteRule ^(.*)$ http://www.example.com.10.0.1.13.xip.io/$1 [R=permanent,L] </IfModule> Or perhaps I don't need to change the htaccess file, is there something that I could be missing in the MAMP Pro settings, or perhaps a MAMP extension that I need?

• Expand disk space on Ubuntu 10.04 (VMWare Guest)

  - by Jason Clawson

  I need to resize the disk space of an ubuntu guest in VMWare Workstation. After using the expand disk utility in vmware workstation, I need to do some linux magic to resize the parition.

• Linux commands shows different results

  - by ClydeFrog

  I'm really having a hard time to process these results on my Ubuntu server. I have a major problem with my JBoss server where I get FileNotFoundExceptions along with "No space left on device" errors. And I thought "maybe I'm out of disk space", and used df command to figure out how much I have left: root@ubuntu1:/# df -h Filsystem Storlek Anvnt Tillg Anv% Monterat på /dev/mapper/ubuntu1-root 36G 13G 21G 38% / none 2,0G 192K 2,0G 1% /dev none 2,0G 0 2,0G 0% /dev/shm none 2,0G 64K 2,0G 1% /var/run none 2,0G 0 2,0G 0% /var/lock /dev/sda1 228M 23M 193M 11% /boot /dev/mapper/vgdata-lvdata 79G 9,2G 66G 13% /data And as you can see, I have plenty of space left. And I also checked if I'm out of i-nodes: root@ubuntu1:/# df -i Filsystem Inoder IAnv IFria IAnv% Monterat på /dev/mapper/ubuntu1-root 2346512 61992 2284520 3% / none 505380 773 504607 1% /dev none 507383 1 507382 1% /dev/shm none 507383 30 507353 1% /var/run none 507383 2 507381 1% /var/lock /dev/sda1 124496 230 124266 1% /boot /dev/mapper/vgdata-lvdata 10486784 233945 10252839 3% /data But then i used du: root@ubuntu1:/# du -s -h /* 7,5M /bin 23M /boot 19G /data 192K /dev 11G /eniro 5,3M /etc 112K /home 0 /initrd.img 183M /lib 0 /lib64 16K /lost+found 12K /media 4,0K /mnt 4,0K /opt du: kan inte komma åt "/proc/20452/task/20452/fd/3": Filen eller katalogen finns inte du: kan inte komma åt "/proc/20452/task/20452/fdinfo/3": Filen eller katalogen finns inte du: kan inte komma åt "/proc/20452/fd/3": Filen eller katalogen finns inte du: kan inte komma åt "/proc/20452/fdinfo/3": Filen eller katalogen finns inte 0 /proc 18M /root 8,2M /sbin 4,0K /selinux 8,0K /srv 0 /sys 40K /tmp 691M /usr 1,2G /var 0 /vmlinuz Notice that /data and /eniro are 30G combined!

But how come it says 9,2G on the first command when it says 19G on the third on directory /data?

• Split MPEG video from command line?

  - by Tim

  I have a homemade DVD that I'm effectively trying to insert chapters into and rearrange - the original author burned it as one long chapter, and I'd like to rip it into smaller pieces and re-encode it into a new DVD. I ripped the DVD with the following command: mplayer dvd:// -dvd-device /dev/sr2 -dumpstream -dumpfile raw.vob I'm running Gentoo Linux with mplayer version 1.0-rc2_p20090731 (the latest available in Portage). I have a list of times that the chapters are supposed to span (for example 30:11-33:25), so my first thought was to rip the entire DVD and use mpgtx to cut out certain pieces of the file. My issue is that running mpgtx -i on the file reports quite a few timestamp jumps: Time stamps jumped from 59.753789 to 0.001622 at position 1d29800 Time stamps jumped from 204963823030450.343750 to 31.165900 at position 2d4f800 Time stamps jumped from 60.077878 to 0.001622 at position 43cc000 Time stamps jumped from 60.024233 to 0.001622 at position 65c5000 Time stamps jumped from 204963823068631.718750 to 52.549244 at position 7fd1000 I've tried to fix the indexes using: mencoder raw.vob -oac copy -ovc copy -forceidx -o fixed.vob -of mpeg But mpgtx will still report timestamp issues. My immediate question: is there a way to take the ripped movie I have and correct its timestamps so I can cut it with mpgtx? If I can get that one issue out of the way, building the rest of the DVD will be smooth sailing. If it's not possible to fix the timestamps on this file: is there a better way to rip small chunks of the DVD into separate files for recompilation later? I'd very much like this to be done on Linux, and it'd be even better if I could script it somehow (feed in a list of start and end positions, or start times and durations, and get out a series of ripped files). If need be, I also have a Mac OS X machine available, but no Windows. Edit: I wound up finding another solution involving HandBrake and ffmpeg (with help from this question), but the question stands. Edit again: Turns out my other solution didn't quite work - the audio desynchronized by about five seconds, in about half of my cut mpgs - so I'm back to square one. Anyone?

• Reliable applicance for routing IT emergency calls (SIP and ISDN)

  - by chiborg

  We have a fairly big IT installation and our IT staff needs to be reachable 24/7. At the moment we have the following setup for "emergency" calls to our IT staff on our main Asterisk box: An incoming emergency number (connected via SIP trunk and a BRI card in case the SIP trunk goes down). When the number is called during the office hours, all the SIP phones of the IT staff are called simultaneously. When the number is called out of office hours interface, a list of mobile phone numbers is called, one after another until someone picks up. The list can be changed by the IT staff via command line script. The setup works well, but the Asterisk is heavily used in a call center, has experienced some outages and misconfigurations, each of them bringing down the IT emergency number. So we'd like to put the IT emergency call functionality on a separate device. This does not need to be a big server, it even does not need to be Asterisk, it only has one purpose and should do it reliably. It should be very low-maintenance. Any suggestions for hard- and software?

• How can I uninstall Broadcom Bluetooth software that won't disappear in Windows XP?

  - by T. Webster

  My situation is similar to this question for Windows 7, except my OS is Windows XP SP3. I have recently realized I made the mistake of buying a Bluetooth adapter and installing the Broadcom/Widcomm Bluetooth stack driver software. Now that I know that the software is no good, I want to uninstall it. Then I'll install the Toshiba stack for the Cirago adapter. Right now, when I double-click on the setup.exe file that came with the Cirago driver, nothing happens (it doesn't start setup). I've attempted to uninstall all Bluetooth driver software in Device Manager, and I don't see any remnants of any Bluetooth drivers there. But I do see that the little Bluetooth icon still persists: I don't see anything about Bluetooth, Broadcom, or Widcomm in Add/Remove Programs. I don't see any folder names Broadcom or Widcomm in Program Files folder, either. But I do see that Broadcom does show up in the registry with respect to Bluetooth, as shown here. I also renamed every file in C:\Windows\inf that starts with "bth" so that it ends with ".old". What should I do now to completely wipe this persistent Broadcom Bluetooth software off my computer?

• What does a connection timeout indicate when performing an NFS mount?

  - by DeeDee

  We have a shiny new QNAP NAS (TS-879U-RP), and I'm trying to mount it to our big ol' RHEL server in the same manner as our other two QNAP NAS devices. The IT department won't give me the root privileges to the NAS, so I can't SSH in (I know, I know). The first thing I did was to, via the QNAP web admin interface, create a network share named "Runs." I then added the IP of the RHEL server to the permissions list: On the RHEL server, I then added the following line to /etc/fstab: [IP of NAS]:/Runs /mnt/gsrnas3 nfs defaults 0 0 Aside from the IP and the specific mount directory name, this is how I mounted the other two NAS devices. I then created the gsrnas3 directory under /mnt/, and then ran `mount /mnt/gsrnas3' I got the following error: mount.nfs: Connection timed out My first thought is that it's a ports issue, but I don't have enough specific experience with this issue to know for sure. I have two other NAS devices by the same manufacturer already mounted to this RHEL server, so that leads me to believe the configuration issue is on the NAS side of things. I can ping the NAS device successfully from the RHEL server. Not being able to SSH into said NAS is a huge hassle, though. Any ideas?

• Eee PC Seashell series netbook screen is cut off at bottom no matter the resolution

  - by Yzmir Ramirez

  I have an Eee PC 1015PE Seashell netbook running Windows 7 Home Premium with an Intel Graphics Media Accelerator 3150 (8.14.10.2230) with a "Generic Non-PnP Monitor" detected. I tried: Changing the resolution (Control Panel = Appearance and Personalization = Display = Screen Resolution) to 1024x768 Updating the video driver (to 8.14.10.2230) Uninstalling the driver and rebooting Pressing the Windows Key + "-" (magnifier) Pressing Ctrl + Mouse Scroll only resizes the desktop items Pressing Fn + F4 shows 1024x600 (which I think is what I should be using, but nothing happens) EDIT: Changed from Landscape to Portrait and it works Attached an External Monitor and when I extend or set as desktop it works only on the External Monitor (shows up as "Generic PnP Monitor in Device Manager) Basically the bottom inch of my desktop is off-screen hiding my start bar, but my wigets are in their proper position (the start bar is not hidden). Pressing Ctrl + Esc shows the start menu but its cut-off. I'm pretty sure I should be using 1024x600 resolution, any advice? What's odd is that this only started happening recently. EDIT2: Here are some screenshots showing the problem: Resized Window to fit: Opened Start Menu - notice it cut off: Maximized window and then scrolled down - notice no Start Menu: I downgraded my graphic driver I downloaded from the Intel Download Center for the Graphic Media Accelerator 3150 (now: 8.14.10.1972) and now my "Generic non-PnP Montior" detects as "Digital Flat Panel (1024x768 60Hz)".

• how would it be possible to discover a cable modem's MAC remotely?

  - by amateurenthusiast

  i was reading the back archives of a canadian privacy law blog, and he linked to a judicial decision. apparently as part of an investigation in which were used yahoo chat and google's old 'hello' image trading program the officer was able to determine a suspect's modem's MAC address: In order to determine who STEPHTOSH was, the officer did a trace on a programme called WHO IS in an effort to learn from where STEPHTOSH was coming. WHO IS is a command program available to the public. The officer was able to ascertain that the person using the name STEPHTOSH was a Rogers Internet customer. The officer was able to obtain the Internet Protocol address, also known as the I.P. There is only one location for an I.P., which is unique to that subscriber. By use of the website known as DNS STUFF.com, one is able to find with which company this I.P. is registered. It was ascertained that the I.P. address used by STEPHTOSH was registered to Rogers Cable, from the Toronto area. The officer also learned the Cable Modem MAC address used by STEPHTOSH. This was all the information the officer was able to amass. now it was my understanding that the MAC address of any given device can only be accessed if you're only one 'hop' away on the Internet. the suspect in question was in Markham and the officer part of the Toronto Police, so it's conceivable that they both might have used Rogers internet. but would that still put them only one 'hop' away from each other? i thought the first hop after the modem was usually the ISP? and if he'd used a netBIOS query against this guy's machine it would return the ethernet card's MAC, not the modem's. so is this guy on the same rogers subnet as the suspect's cable modem, is that functionality part of google's Hello (i could only think that it would be possible if Hello operated as a virtual LAN or something), does the officer have remote access to the arp caches of the routers at Rogers or is he just full of crap and lying to make his case stronger?

• Debian - starting UFW (Uncomplicated Firewall) before network interfaces are operational

  - by Tomasz Zielinski

  I want to install UFW on Debian Lenny. Everything looks straightforward except that I don't know where to plug UFW startup script so that it configures iptables before hax0rs can break in. I've reviewed runlevel directories and in /etc/rc0.d, /etc/rc6.d and /etc/rcS.d there are items like these: S35networking -> ../init.d/networking S36ifupdown -> ../init.d/ifupdown Runlevel 0 and 6 are for shutdown and reboot so I guess nothing should be changed there, but runlevel S advertises itself (in README) like something for me: The scripts in this directory whose names begin with an 'S' are executed once when booting the system, even when booting directly into single user mode. The following sequence points are defined at this time: * After the S40 scripts have executed, all local file systems are mounted and networking is available. All device drivers have been initialized. (What bothers me is that both rc0/6.d and rcS.d point to the same networking and ifupdown scripts, but after looking at sources I believe those scripts are smart enough to figure out where to start and where to stop networking.) Now, I think that I should plug my /lib/ufw/ufw-init into /etc/rcS.d, with priority higher that the one of ifupdown and networking, i.e. <= 38 for my /etc/rcS.d. Am I right in this "analysis" ?

• No headphone or speakers plugged in - Windows 7 issue

  - by Amit Ranjan

  I am facing a wierd issue between my sound card driver and Windows7(any edition). I have a sony vaio notebook (VPCEB24EN). Two days ago, on start I got diabled wifi, charging and speakers. Then I restart the PC and everthing worked fine. Later on I again restarted my machine, and then I found the my speakers were not working. I thought, restart will work. I restarted many more times but it did'nt work. I searched google and found that , it might be due to : 1. Hardware is not switched on from bios. 2. No hardware. 3. overriding 64-bit drivers with 32-bit drivers. To make it working, I restored my laptop from scratched, but while restoring pc, the realtek HD drivers, it gave me an error 505. I then formatted the drive and installed Win7 Ultimate 32bit (With PC was, Win7 64-bit Home Basic). I got lots of yellow exclamation in device manager, thinking now this will resolve my issue. But Even after the installing all drivers on a fresh installation, I was still with the same position. A red cross on speaker- No Speakers or Headphone plugged in. Please Note: My Laptop is Vaio , E Series, VPCEB24EN. Audio : Intel® High Definition Audio compatible but accepts Realted Audio. While using BIOS Agent, I got Intel Chipset 5 Series Audio Adapter and ATI RV370 Audio adapter found on my board. Installed is Win7 32bit Ultimate. factory default was Win7 64-bit Home Basic Memory: RAM 3GB/ 320GB HDD Display : ATI Mobility Radeon™ HD 5145 Graphics

• Why does my DSDT table is different from what I found online?

  - by Hao Shen

  I have found a field in DSDT table where I want to modify from here http://www.ztex.de/misc/c2ctl.e.html Generally, I want to modify the _PSS field about the processor so that I can have more frequency levels available in the CPUfreq driver interface. I try to use this command to dissemble the DSDT table from my Desktop(Linux2.6.29,Intel CORE 2): cat /proc/acpi/dsdt > dsdt.aml iasl -d dsdt.aml Then I have a file dsdt.dsl as following(very long, so I just show the beginning of the file): /* * Intel ACPI Component Architecture * AML Disassembler version 20090123 * * Disassembly of dsdt.aml, Mon May 6 20:41:40 2013 * * * Original Table Header: * Signature "DSDT" * Length 0x00003794 (14228) * Revision 0x01 **** ACPI 1.0, no 64-bit math support * Checksum 0x46 * OEM ID "DELL" * OEM Table ID "dt_ex" * OEM Revision 0x00001000 (4096) * Compiler ID "INTL" * Compiler Version 0x20050624 (537200164) */ DefinitionBlock ("dsdt.aml", "DSDT", 1, "DELL", "dt_ex", 0x00001000) { Method (DBIN, 0, NotSerialized) { Noop } Scope (\) { Device (_SB.VBTN) ................... But I can not find the _PSS field as shown in the website I have given above. I do not know why? I am sure the current cpufreq driver shows 4 frequency levels available. So at least there should be something in the table showing this..right? Has anybody here played with the DSDT table before? Thanks,

• How to reinstall Windows Boot Manager on EFI partition

  - by joaocandre

  So I've been trying to install Ubuntu on a second HDD on my desktop, which has W8 installed on a SSD (UEFI-only boot). Thing is, during Ubuntu installation I made the mistake of choosing to install the bootloader (GRUB) to the first disk (the SSD), and after install I could not boot into W8 (the entries in GRUB didn't work). Following these instructions, I managed to be able to get "Windows Boot Manager" back, however I lost GRUB in the process, and got a duplicate "Windows Boot Manager" entry in BIOS, along with the "Ubuntu" entry, which then I used to boot into Ubuntu. Later, I decided to reinstall Ubuntu, and formatted the HDD from within windows, however, the entries in BIOS stayed the same, and, while I had the HDD connected to the motherboard, I could not boot into an Ubuntu Live USB (in order to reinstall Ubuntu). I made another mistake by updating the BIOS, which cleared all of the EFI boot entries in BIOS, and, right now, I get an error when boot from the SSD: grub: device not found (...) So it seems that grub is still installed in the EFI partition of the SSD, and since I don't have the WBM entry in BIOS anymore, I cannot even boot into Windows, and the previous instructions don't work anymore. Is there another way to reset W8 EFI partition to the default?

• How to disable "safely remove hardware"

  - by Matt

  I have some windows 7 virtual machines in xen that have devices showing up in "safely remove hardware". I don't want users to ever be able to remove/eject any hardware at all. I'm told vmware has a hotplug option. xen doesn't seem to provide this for pci passthrough devices, therefore I'm looking for a reliable solution to prevent users from ejecting devices. This issue is not necessarily related just to virtual machines but seems to be a common problem with devices that get wrongly reported as removable. I'm ideally looking for a way to prevent all devices from appearing or just prevent the safely remove hardware option from ever coming up. I've tried setting device capabilities for specific devices on boot with a script but this for some reason doesn't always seem to work reliably. Is there a way to prevent this icon from appearing in the notification area completely, either by registry key or group policy? I should point out that setting this in group policy to "Administrators" did not seem to work.

• Xorg input devices fail without udev

  - by Sampo

  What I am trying to do: Launch Xorg server without udev device manager. What I have tried to do: Make sure that /dev/ has all required nodes, such as /dev/input/*. Make sure that all required kernel modules are loaded. Launch Xorg. What happens: Xorg starts up as excepted. Xorg loads correct GPU driver and sets right screen resolution. Xorg blocks all input devices (keyboard, mouse), Alt+F[1-12] does not work (can't go back to tty1). Unraw'ing keyboard to take its control from X removes blocking and after unraw I can Alt+F1 back to tty1. Xorg still does not handle any input. Why I think that it should work: Same configuration works well if udev is loaded. Loading udev does not add or modify /dev/ contents, all nodes stays same. My main question is: How to make Xorg input devices work without udev? Any additional information about how Xorg really uses/detects/grabs keyboard would be helpful. And any additional information about what udev really does (other than populating /dev/) would also be helpful.

• Firebox 1250e Core Failing?

  - by Noah

  We have 2 Firebox 1250e Core firewall boxes in our production environment, serving as an active and passive mode. A few months back, the active box was flashing a warning light, so our consultant removed it, and plugged it in to a test network. Everything appeared to be working fine, so he reloaded it into the production environment, and we didn't see any other issues. Fast forward to last week, and out network was constantly dropping connections over RDC, timing out, and performing as if there was a traffic issue. I turned off the production box and everything began to work fine immediately. At this point though, I'm not sure how to proceed. Should the box be completely replaced? Is there any recommended testing we could do to determine if there is a failure of some type with this device? Should we try upgrading the software on it? I know the environment isn't the issue, since the passive box (which is now the active one) is working fine. We'd like to have 2 in production though for safety failover purposes. I am not a network admin, but am hoping someone here might be able to provide some guidance.

• recursive grep started at / hangs

  - by Martin

  I have used following grep search pattern on multiple platforms: grep -r -I -D skip 'string_to_match' / For example on FreeBSD 8.0, FreeBSD 6.4 and Debian 6.0(squeeze). Command does a recursive search starting from root directory, assumes that binary files do not have the 'string_to_match' and skips devices, sockets and named pipes. FreeBSD 8.0 and FreeBSD 6.4 use GNU grep version 2.5.1 and Debian 6.0 uses GNU grep version 2.6.3. On FreeBSD 6.4, last information printed to stderr was "grep: /dev/cuad0: Device busy". After this grep just idles as according to "top -m io -o total" the I/O usage of grep is nonexistent. Same behavior is true under FreeBSD 8.0, but last information sent to stderr is "grep: /tmp/.wine-0: Permission denied" on my installation. In case of Debian, last output to stderr is "grep: /proc/sysrq-trigger: Input/output error". If I check the I/O usage of grep process under Debian, it is following: root@Debian:~# iotop -bp 22439 Total DISK READ: 0.00 B/s | Total DISK WRITE: 0.00 B/s TID PRIO USER DISK READ DISK WRITE SWAPIN IO COMMAND 22439 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.00 % grep -r -I -D skip 10.10.10.99 / Total DISK READ: 0.00 B/s | Total DISK WRITE: 0.00 B/s TID PRIO USER DISK READ DISK WRITE SWAPIN IO COMMAND 22439 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.00 % grep -r -I -D skip 10.10.10.99 / Total DISK READ: 0.00 B/s | Total DISK WRITE: 0.00 B/s TID PRIO USER DISK READ DISK WRITE SWAPIN IO COMMAND 22439 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.00 % grep -r -I -D skip 10.10.10.99 / ^Croot@Debian:~# What might cause this? Is there a way to view which file grep is currently processing in case lsof is not present? I'm able to use lsof under Debian and looks like the problematic file name there is "0xc6b2c230 file struct, ty=0, op=0xc0d34120". I'm not sure what this is.. I'm not able to use lsof or fstat under FreeBSD. PS: I know I could use find utility, but this is not the question.

• Tidy up old Windows Server Backup snapshots

  - by dty

  Hi, I'm running wbadmin from a scheduled job, backing up my C: and D: drives to my E: and (I believe!) including the system state: wbadmin start backup -backuptarget:e: -include:c:,d: -allCritical -noVerify -quiet I'd like to delete old backups, but I'm concerned that all the information I can find says to use wbadmin to delete old system state backups, and vssadmin to delete other backups. As far as I know, my backups ARE system state backups, but are using VSS on E: for storage, so I'm worried about trying either of these techniques for fear of losing all my backups. This is a home network, so I don't have a spare server to test this on. I'm also happy to simply restrict the space used on E:, but I can't make sense of the difference between the /for and /on parameters of the relevant vssadmin command. For reference, here's the output of vssadmin show shadows: Contents of shadow copy set ID: {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} Contained 1 shadow copies at creation time: 07/01/2011 08:12:05 Shadow Copy ID: {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} Original Volume: (E:)\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\ Shadow Copy Volume: \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy83 Originating Machine: x.y.com Service Machine: x.y.com Provider: 'Microsoft Software Shadow Copy provider 1.0' Type: DataVolumeRollback Attributes: Persistent, No auto release, No writers, Differential [... repeated a lot...] vssadmin show shadowstorage: Shadow Copy Storage association For volume: (C:)\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\ Shadow Copy Storage volume: (C:)\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\ Used Shadow Copy Storage space: 0 B Allocated Shadow Copy Storage space: 0 B Maximum Shadow Copy Storage space: 5.859 GB Shadow Copy Storage association For volume: (D:)\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\ Shadow Copy Storage volume: (D:)\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\ Used Shadow Copy Storage space: 0 B Allocated Shadow Copy Storage space: 0 B Maximum Shadow Copy Storage space: 40.317 GB Shadow Copy Storage association For volume: (E:)\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\ Shadow Copy Storage volume: (E:)\\?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}\ Used Shadow Copy Storage space: 168.284 GB Allocated Shadow Copy Storage space: 171.15 GB Maximum Shadow Copy Storage space: UNBOUNDED wbadmin get versions: Backup time: 07/01/2011 03:00 Backup target: 1394/USB Disk labeled xxxxxxxxx(E:) Version identifier: 01/07/2011-03:00 Can Recover: Volume(s), File(s), Application(s), Bare Metal Recovery, System State [... repeated a lot...]

• How do I setup routing for 2 companies with different Internet connections on the same LAN?

  - by Clint Miller

  Here's the setup: 2 companies (A & B) share office space and a LAN. A 2nd ISP is brought in and company A wants it's own Internet connection (ISP A) and company B wants it's own Internet connection (ISP B). VLANs are deployed internally to separate the 2 company's networks (company A: VLAN 1, company B: VLAN 2, shared VOIP: VLAN 3). With separate VLANs it's simple enough to use separate DHCP servers (or separate scopes on the same server) to assign the default gateway to each company's gateway for their Internet connection. Static routes can be created on each gateway to point traffic destined for the other company's VLAN or the voice VLAN so that all nodes are reachable as expected. However, I think this is a form of asymmetrical routing, right? (The path from node A1 to node B1 is not the same as the path back from node B1 to node A1). Can I setup policy-based routing to correct this? In that case, can I assign the same default gateway to every device on all VLANs and create a routing policy on a L3 switch to look at the source address and forward traffic to the appropriate next hop? In that case, I want the routing logic to go like this: If the destination address is known, forward the traffic (traffic destined for a different VLAN). If the destination address is unknown, forward the traffic to ISP A's gateway if the source address is on VLAN A; or forward the traffic to ISP B's gateway if the source address is VLAN B. Am I thinking about this problem in the correct way? Is there another way to solve this problem that I am overlooking?
