  • How can I get rsync to ignore missing files?

    - by Joe Casadonte
    I'm executing a command like the following to several different systems: $ rsync -a -v [email protected]:'/path/to/first/*.log path/to/second.txt' /dest/folder/0007/. Sometimes *.log does not exist, and that's OK, but rsync generates the following error: receiving file list ... rsync: link_stat "/path/to/first/*.log" failed: No such file or directory (2) done Is there any way to suppress that? The only way I can think of is to use include and exclude filters, which just seem a PITA to me. Thanks!

  • High frequency, kernel bypass vs tuning kernels?

    - by Keith
    I often hear tales about High Frequency shops using network cards which do kernel bypass. However, I also often hear about them using operating systems where they "tune" the kernel. If they are bypassing the kernel, do they need to tune the kernel? Is it a case of they do both because whilst the network packets will bypass the kernel due to the card, there is still all the other stuff going on which tuning the kernel would help? So in other words, they use both approaches, one is just to speed up network activity and the other makes the OS generally more responsive/faster? I ask because a friend of mine who works within this industry once said they don't really bother with kernel tuning anymore-because they use kernel bypass network cards? This didn't make too much sense as I thought you would always want a faster kernel for all the CPU-offloaded calculations.

  • How do I know when my on-board ethernet is dead? (Realtek 8112L LAN controller w/ AI NET2 )

    - by Usagi
    So I have an ASUS P7P55D-E Pro motherboard. It has an on-board Realtek 8112L LAN controller w/ AI NET2. I suspect that my LAN controller is dead but I don't really know for sure. This is what I know thus far: Everything was working, I have a triple booted system and ethernet was functional under Linux, Win7, and OSX. My ethernet is no longer functional under all three of the operating systems. I was experiencing random momentary internet outages before everything finally went dark. I don't know much about the AI NET BIOS tool but I believe it just checks for ethernet problems before you boot into an operating system. In any case, it doesn't find a connection upon boot. I've checked the connection on a couple of other machines and everything worked fine. I think I already know the answer to my question, but are there any other possible explanations, or is it dead?

  • PC3200 RAM in Older Computer?

    - by skaz
    Hello all, I am inheriting a Dell Dimension 8200, but it needs RAM to get up and running. I have PC3200 sticks lying around, but I am not sure how to go about figuring out if the RAM is compatible, as RAM has always confused me. Here is the Dell Dimension 8200 Tech Specs: http://support.dell.com/support/edocs/systems/dim8200/specs.htm For RAM, it says: Memory type PC800 (non-ECC) I don't know if that is just the kind that comes with it, and I can put in PC3200 (I think, if it worked, this would run at the lower rating? Is that true?), or if that means only PC800 is compatible. Any help would be appreciated.

  • How to use ssh-agent (and graphic passphrase dialog) in Kubuntu 10.10?

    - by halo
    I have recently switched from Ubuntu to kubuntu, both version 10.10. Unfortunately in KDE the ssh passphrase dialog doesn't work out of the box. Everytime my ssh private key is used I need to enter my password. This is neither secure nor comfortable. I have done comprehensive research on the net but only found out dated documentation. Several things I tried didn't work out. Current status: SSH setup working with direct passphrase input ssh-agent running in X session $SSH_AUTH_SOCK set to ssh-agent's socket in X session How to enable ssh-agent for keeping the passphrase in memory for ~15mins and as a bonus always use a graphical dialog for its input? I use asymmetric SSH key pairs for pushing/pulling in Git VCS logging remotely into different server systems

  • Compaq Presario V2000 Vista/7 trial virtualization

    - by James Schweninger
    I am currently studying for an A-Plus certification to which was recently added troubleshooting Windows 7 to the exam. You also have to be very familiar with Vista as well. I only have XP on my Compaq Presario V2000, but I wanted to set it up ( I believe I have the minimum requirements for both ) so that I could run trial versions of Vista and 7 virtually.Windows 2000 is also on the exam. Is there an easy legal way to do this? I wouldn't mind partitioning my HDD for the four operating systems either. Thnx if you have any ideas, JLS

  • Ubuntu Linux -- create custom burnable/bootable DVD image?

    - by ashgromnies
    I recently developed some kiosk software that runs on Ubuntu Linux, and my client needs me to set up ten more computers with the complete software package(and that number will only grow in the future). So I'm looking for a way to make this less of a pain in the neck and prevent me from shooting myself in the foot -- I had to disable some things on the installations of the operating systems like screensavers, automatic updates, etc. that would pop up and disrupt the kiosk operation. I don't feel comfortable doing that by hand across 10 computers, it seems stupid. Does anybody have recommendations for software that would let me burn an installable DVD with a complete image of the hard drive from one of the devices? I've looked at Clonezilla, G4L, and PartImage and I'm still not quite sure if any of them offer what I need. I know PartImage for sure won't work, because it doesn't support Ext4.

  • Windows 7 Intermittent Connection Issues (Continuously "identifying")

    - by andrewktmeikle
    I have an issue solely with my desktop windows 7 machine on my network (the network has multiple different devices, on the same and different operating systems) and the issue is that irregularly, although sometimes frequently, I briefly get disconnected from the internet (briefly is for around 5-10 seconds). However, I never loose the bars on the wifi thing, eg I don't get the yellow triangle, but it goes to the identifying stage and then reconnects. The reason I noticed the problem was when I was streaming music it would stop and I would refresh the page and it would start working again ( turned out it was because it took that amount of time to get connected again). So my question is, what would cause the intermittent issues and start the "identifying" process again. I don't think its my router, because no one else is having problems, so the other option is that its a problem specifically with my machine. I'm connecting to a Netgear DG834GT router, and I'm using a Edimax Wireless-N150 USB Adapter. Anyone have any ideas?

  • Can the traditional remote desktop client be accessed in Windows RT?

    - by nhinkle
    As mentioned in another question, I've been unable to connect through the Remote Desktop metro app to some computers, in particular those requiring VPN access or load balancers. I'm considering purchasing a Microsoft Surface RT, but given that the app store hasn't matured significantly yet and some niche software will likely never be ported to the Modern UI, I must have acess to remote systems somehow. Until Citrix fixes the receiver app for Windows 8, I'm stuck using remote desktop. Which doesn't work. I've heard that Windows RT comes with some of the Microsoft desktop programs built in, like Microsoft Office and File Explorer. Is the "normal" Remote Desktop Connection program available in Windows RT, and if so, is it 100% compatible with previous versions?

  • UTF-8 locale portability (and ssh)

    - by kine
    I spend a lot of my time sshed into various machines, all of which are different (some are embedded, some run Linux, some run BSD, &c.). On my own local machines, however, i use OS X, which of course has a userland based on FreeBSD. My locale on those machines is set to en_GB.UTF-8, which is one of the available options: % echo `sw_vers` ProductName: Mac OS X ProductVersion: 10.8.2 BuildVersion: 12C60 % locale -a | grep -i 'en_gb.utf' en_GB.UTF-8 Several of the more-capable Linux systems i use appear to have an equivalent option, but i note that on Linux the name is slightly different: % lsb_release -d Description: Debian GNU/Linux 6.0.3 (squeeze) % locale -a | grep -i 'en_gb.utf' en_GB.utf8 This makes me wonder: When i ssh into a Linux machine from my Mac, and it forwards all of my LC_* variables with that 'UTF-8' suffix, does that Linux machine even understand what is being asked of it? Or is it just falling back to some other locale? In either case, what is the mechanism behind its behaviour, and is it dependent on any particular set-up (e.g., will i see the same behaviour on a BusyBox-based system as on a GNU-based one)?

  • Is it possible to run a "Windows Server 2008 R2 SP1 Hyper-V Virtual Machine" on Windows 7x64 Pro machine?

    - by tbone
    Specifically, I want to run this: http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=27417 This download contains a three Windows Server 2008 R2 SP1 Hyper-V Virtual Machine set for evaluating and demonstrating Office 2010, SharePoint 2010 and Project Server 2010. System requirements Supported operating systems: Windows Server 2008 R2 Additionally you will need: •Windows Server 2008 R2 (SP1 recommended) with the Hyper-V role enabled. •Drive Formatting: NTFS •Processor: Intel VT or AMD-V capable •RAM: 8 GB or more recommended •Hard disk space required for install: 100 GB ------------------------- So, the above text seems to indicate that you need a physical Windows 2008 Server (r2) server running, but from the googling I've done on the subject I've yet to come across a discussion that definitively answers the question. Many posts I've read seem to indicate it might be possible to run it on Windows 7 using one of the following: VirtualBox, Windows Virtual PC, VMWare but I'm not entirely sure.

  • OSSIM - Snort/OSSEC/Nagios Logging Config Question

    - by user15736
    Quick n00b OSSIM question. I've looked around but haven't found exactly what I'm looking for. I currently have a Nagios, OSSEC, Nessus, and Snort server and I want to keep those servers active but just ship the logs to the OSSIM server and have it do the correlating and graphing. Can that be done? Everything I've seen is putting the various software functions actually on the OSSIM box but I don't want to do that. I'm running CentOS on all of the systems. Thanks.

  • General purpose ticketing/tech support system [closed]

    - by crazybyte
    Possible Duplicate: What’s your favorite ticketing system? I was wondering if somebody could recommend me a very user friendly or simple general purpose ticketing/tech support system. I need something that is web based, preferably open-sourced/free software implemented using PHP, Ruby, Ruby on Rails or Java (as back end) with MySQL or PostgreSQL as database engine. I need something that is not development management oriented or project management oriented like Eventum or similar (random example), something to which the user can connect open a tech support request and be able to follow it until is solved or dropped.I need it to be open-sourced to be able to modify it if there is a need or extend it. I tried a number of such systems available and I found that osTicket or eTicket is something that it's close to what I need, but the code is somewhat flaky and some of the features are working badly or behaving strangely. Any thoughts/advice where to find something similar? Thanks!

  • Distributed filesystem for automated offline data mirroring

    - by Petr Pudlák
    I'd like to achieve the following setup: Every time I connect my laptop to a local network, my partition gets automatically mirrored to a partition on my local server. I only want to mirror what has changed from the last time. (I understand that it is not a proper backup solution since there is no history of the changes, it'd be more like a non-persistent network RAID.) Is there a distributed file system that allows such a setup? I've done some searching and it seems to me that most distributed file-systems are focused on data availability and distribution, not duplicating them. I'd be thankful for suggestions. Edit: Sorry, I forgot to mention: I'm using Linux.

  • Tracking down laptops Google has never heard of

    - by John
    Using MS tools to get information on PCs using our software, our customers have sent several Lenovo systems which have names we simply cannot find using Google... no search results at all. Considering these names/ids are returned by querying the system directly, not asking the customer to write it down by looking at the box, this seems odd. The ones we have so far (more than one of each) are: Lenovo 2241BL9 Lenovo 6463Y4H My guess is these are Thinkpads after Lenovo took over the brand, but can anyone help me out with this detective work? edit: the 2nd one does turn up some driver downloads and this page, but it's unclear what any of that means. Is the 6463y4h just a T61? http://smolts.org/reports/view_profile/%20ThinkPad%20T61

  • How can I use rsync with a FAT file system?

    - by Kim
    I would like to write a simple backup script that saves some data to a FAT drive. Should I reformat the drive and use a better file system or is it possible to use rsync with FAT? If so, what problems might I run into? Would performance be a lot worse? EDIT: This is on linux, didn't even know there was a rsync for windows. The sources are various file systems (it's a mess), and the destination is currently formatted with FAT32. Thank you for your answers, I'll probably go for a reformat, since I'm not completely sure about the file sizes we'll have.

  • DNS record reappears after having been deleted

    - by palmbardier
    I've got a Microsoft Windows Server 2003 R2 acting as a domain controller for a small network. It provides DHCP and DNS among a few other services. It's only got a single NIC, but it's configured with two IP addresses. I want it's name to resolve to one of the two IP addresses assigned to its NIC. I've unchecked "Register this connection's addresses in DNS" under the "Advanced TCP/IP Settings". Currently we've got two distinct DNS Host (A) records for this domain controller: dc-001 - 10.0.0.1 dc-001 - 10.0.100.1 I've deleted the first entry but it continues to reappear in my dnsmgmt snap-in. Unfortunately I'm not a Microsoft systems administrator by trade. Does anyone familiar with Microsoft server environments know why a deleted Host (A) record would reappear? Is there another check-box I need to toggle? Thanks in advance to all of you Microsoft experts out there.

  • Windows 8 / Server 2012 RDP connection is slow

    - by Chris
    I recently installed Windows Server 2012 for development purposes at our office and noticed immediately that connecting via RDP is slow. It can take 5-10 seconds to connect at times, where as connecting to any of our Win7 or Win2008R2 boxes takes at most 1-3 seconds. At first, I chalked this up to the box itself needing a driver update or something, but just yesterday, I installed Win8 on my desk PC and connecting from home to that machine produces the same result. There is a 3-4 second pause at "securing remote connection" and then again at "configuring remote session". I don't see any warnings in the event log, and once connected, there do not appear to be any performance issues. Is there a known problem with RDP connections on Windows 8 systems? Anything I should look for?

  • Do I need to reserve space before installing Ubuntu alongside Windows 7?

    - by CRM Junkie
    I had Windows 7 32 bit on my existing system, but I am planning to install Ubuntu alongside it. So, I just decided to do a fresh installation of both the operating systems. When I insert the Windows 7 DVD, I can create 3 partitions at maximum, with one being the one where Windows 7 will be installed. I just wanted to know – do I need to keep some un-partitioned space for Ubuntu to install? By "unpartitioned space" I mean the space left after creating 3 partitions for Windows 7. I have a 500 GB HDD, so the three partitions I would be creating are 120 GB, 120 GB and 120 GB. The rest is shown as some logical drive, is that unpartitioned space? Can I install Ubuntu over there? I am pretty sure the space shown as logical won't be available as drives when I log into Windows 7. Is that space lost or can I use that to install ubuntu?

  • How does Amazon ec2-user get its sudo rights

    - by Johan
    I am looking for where the default Amazon AMI linux image sets up the privileges for the default ec2-user account. After logging in with this account I can use sudo successfully. Checking via the sudoers file, which I open by running visudo (with no other options) I see a few default settings and permissions for root ALL ALL So ... Where is the permissions for ec2-user assigned? I have not yet tried to add a new permission but ultimately I want to resign ec2-user for systems management tasks and use a non-full root user for administering the applications (stop and start mysql, httpd, edit apache's vhost files, and upload / edit web content under the web root)

  • How to view dirty page count in Windows Server 2003

    - by Mark Wilkins
    Is there a way to view the number of dirty pages (cached file pages that need to still be written to disk) in Windows Server 2003? In Windows 7, for example, I can use Performance Monitor and use the "Dirty Pages" counter (one of the cache counters). This counter does not seem to be available in Server 2003. Also on Windows 7 (and other later systems), I can use Sysinternals RAMMap and effectively see the dirty pages on a file-by-file basis. Is there something similar for Server 2003?

  • what poor management decsions have you had to deal with?

    - by tombull89
    As a junior technician I've had to deal with (or will have to deal with) some problems in the past and only being a junior technicain I don't have the confidence or respect from management staff to speak up. For instance, we're having a entirely new system. From Server 2003/XP going to Sevrer 2008 R2/Win7/VMWare/Digital Signage and the current amount of time dedicated to the training of the IT support department currently stands at 0. They seem to think that all it systems are the same and are going to get a bit of shock when I can't help them. I think there;s some UK legislation saying a school/business have to put money and time aside for training, but I'm not sure. What have you had to deal with?

  • Workaround for API limits [closed]

    - by blunders
    Problem: Planning on building out a client services company that requires access to APIs. Most APIs are limited based on user, IP, etc. - and even though the API calls would be on a per client basis, there's no way to get usage not tied to IPs. (Theoretical) Solution: Have each client install on their network a proxy/VPN that would allow my systems to connect and use their assigned usage. So, it's possible there's a better solution than the one I've thought of, but it's the only one I've been able to come up with.

  • Windows Media Player functionality for Ubuntu

    - by Xeoncross
    I have way to many music files to bother with setting up playlists. Especially since my files locations keeps changing as I move stuff around and swap between different computers, different mount points, and even different Operating Systems! So managing my media with any application is doomed to failure. However, since I still want to listen to the music I usually just select all the files I want to play at a time and then right-click to open them in a media player. Works great in windows media player and places all the tracks in a temp playlist on the sidebar. Fails in ubuntu using Rhythmbox since it doesn't understand "temp" playlists and just keeps adding files to your FULL listing of all sings on your whole computer. I have over three copies of some tracks now in my audio collection - and all of them are now invalid because the location of the files has changed. So what media player (for Ubuntu) works well with just temporary playlists and will allow me to open up my files without adding them to a collection?
