  • Is there a way to submit a batch of commands to a Cisco router and have them execute from the router?

    - by atroon
    I need to change the configuration of a remote (6 hours' drive) client's Cisco 871 (IOS 12.4.15T) from my location because of some new internet service at his location. To be more precise, I need to change the default route, ip address of the outside interface (Fa4) and disable the PPPoE setup there. Unfortunately, doing any of this will (obviously) break the connection to the router. I do not have an out-of-band management modem set up (I know, I know). Is there any way to enter the commands I need to have run and have them execute one after the other, from a file on flash:? I have never tried anything like that before. Essentially a DOS-style batch file is exactly what I need. Nothing like it seems to be out there except using kron to execute CLI commands, but that is specified here as only taking EXEC commands, not configuration ones. Is there hope, or do I travel?

  • Cannot ssh anymore into FreeBSD 7.2 home server

    - by Gabi
    Somehow sshd stopped running and no amount of start, restart or onestart will make it go again. I normally ssh into it from a dual-boot laptop computer that shows up on the network as gabi-buntu when running Ubuntu Karmic, and as gabi-pc when running Windows XP Pro. Neither my Putty connection nor the Linux terminal can establish a ssh link anymore. Upon rebooting the server, I am greeted with "/etc/rc: WARNING: run_rc_command: cannot run /usr/sbin/sshd". In addition, a message will appear saying things like rpc.statd: failed to contact host gabi-buntu RPC: port mapper failure RPC: timed out Everything else works fine. The FreeBSD 7.2 box runs a print server, a Samba server, and an Apache server for the home wiki, via https. It also serves up NFS shares for Linux clients. Any suggestions? Thank you, Gabi Huiber

  • How secure is a bluetooth keyboard against password sniffing?

    - by jhs
    In a situation where an admin will enter sensitive information into a keyboard (the root password), what is the risk that a bluetooth keyboard (ship by default with Mac systems these days) would put those passwords at risk? Another way of asking would be: what security and encryption protocols are used, if any, to establish a bluetooth connection between a keyboard and host system? Edit: Final Summary All answers are excellent. I accepted that which links to the most directly applicable information however I also encourage you to read Nathan Adams's response and discussion about security trade-offs.

  • How to set up memcached to use unix socket?

    - by alfish
    While I could use memcached on Debian to use the default 11211 port, but I've had great difficulty setting up unix socket, Form what I'v read, I know that I need to create a memcache.socket and add -s /path/to/memcache.socket -a 0766 To /etc/memcached.conf and comment out the default connection port and IP, i.e. -p 11211 -l 127.0.0.1 However, when I restart memcached I get internal server errors on Drupal site. I'm trying to implement unix sockets to avoid TCP/IP overhead and boost overal memcached performance, however not sure how much performance gain one can expect of this tweak. I appreciate your hints or possibly configs to to resolve this.

  • LinkSys WRT54GL + AM200 in half-bridge mode - UK setup guide recommendations?

    - by Peter Mounce
    I am basically looking for a good guide on how to set up my home network with this set of hardware. I need: Dynamic DNS Firewall + port-forwarding VPN Wake-on-LAN from outside firewall VOIP would be nice QoS would be nice (make torrents take lower priority to other services when those other services are happening) DHCP Wireless + WPA2 security Ability to play multiplayer computer games I am not a networking or computing neophyte, but the last time I messed with network gear was a few years ago, so am needing to dust off knowledge I kinda half have. I have read that I should be wanting to set up the AM200 in half-bridge mode, so that the WRT54GL gets the WAN IP - this sounds like a good idea, but I'd still like to be advised. I have read that the dd-wrt firmware will meet my needs (though I gather I'll need the vpn-specific build, which appears to preclude supporting VOIP), but I'm not wedded to using it. I live in the UK and my ISP supplies me with: a block of 8 static IPs, of which 5 are usable to me a PPPoA ADSL2+ connection

  • Chain Gateways on the LAN

    - by Black2night
    I installed m0n0wall in a virtualized environment, i have 10 PCs connected to a router ( 192.168.1.0/24) which connect them to the internet through PPPoE, the problem is that this router does not have a QoS so what i want to do is the following :- let all the PCs get their IP from the Router and the default gateway will be m0n0wall the moon wall will have 2 interface (Lan 192.168.1.20) and (Wan 192.168.1.21 and default gateway 192.168.1.1) now when any PC want to access the internet it should go through m0n0wall and then m0n0wall will forward the connection to the default gateway through the wan interface which is the PPPoE running on the router (192.168.1.1) the big question is this scenario possible or not and what do you suggest? Thanks

  • 7-Eleven Improves the Digital Guest Experience With 10-Minute Application Provisioning

    - by MichaelM-Oracle
    By Vishal Mehra - Director, Cloud Computing, Oracle Consulting Making the Cloud Journey Matter There’s much more to cloud computing than cutting costs and closing data centers. In fact, cloud computing is fast becoming the engine for innovation and productivity in the digital age. Oracle Consulting Services contributes to our customers’ cloud journey by accelerating application provisioning and rapidly deploying enterprise solutions. By blending flexibility with standardization, our Middleware as a Service (MWaaS) offering is ensuring the success of many cloud initiatives. 10-Minute Application Provisioning Times at 7-Eleven As a case in point, 7-Eleven recently highlighted the scope, scale, and results of a cloud-powered environment. The world’s largest convenience store chain is rolling out a Digital Guest Experience (DGE) program across 8,500 stores in the U.S. and Canada. Everyday, 7-Eleven connects with tens of millions of customers through point-of-sale terminals, web sites, and mobile apps. Promoting customer loyalty, targeting promotions, downloading digital coupons, and accepting digital payments are all part of the roadmap for a comprehensive and rewarding customer experience. And what about the time required for deploying successive versions of this mission-critical solution? Ron Clanton, 7-Eleven's DGE Program Manager, Information Technology reported at Oracle Open World, " We are now able to provision new environments in less than 10 minutes. This includes the complete SOA Suite on Exalogic, and Enterprise Manager managing both the SOA Suite, Exalogic, and our Exadata databases ." OCS understands the complex nature of innovative solutions and has processes and expertise to help clients like 7-Eleven rapidly develop technology that enhances the customer experience with little more than the click of a button. OCS understood that the 7-Eleven roadmap required careful planning, agile development, and a cloud-capable environment to move fast and perform at enterprise scale. Business Agility Today’s business-savvy technology leaders face competing priorities as they confront the digital disruptions of the mobile revolution and next-generation enterprise applications. To support an innovation agenda, IT is required to balance competing priorities between development and operations groups. Standardization and consolidation of computing resources are the keys to success. With our operational and technical expertise promoting business agility, Oracle Consulting's deep Middleware as a Service experience can make a significant difference to our clients by empowering enterprise IT organizations with the computing environment they seek to keep up with the pace of change that digitally driven business units expect. Depending on the needs of the organization, this environment runs within a private, public, or hybrid cloud infrastructure. Through on-demand access to a shared pool of configurable computing resources, IT delivers the standard tools and methods for developing, integrating, deploying, and scaling next-generation applications. Gold profiles of predefined configurations eliminate the version mismatches among databases, application servers, and SOA suite components, delivered both by Oracle and other enterprise ISVs. These computing resources are well defined in business terms, enabling users to select what they need from a service catalog. Striking the Balance between Development and Operations As a result, development groups have the flexibility to choose among a menu of available services with descriptions of standard business functions, service level guarantees, and costs. Faced with the consumerization of enterprise IT, they can deliver the innovative customer experiences that seamlessly integrate with underlying enterprise applications and services. This cloud-powered development and testing environment accelerates release cycles to ensure agile development and rapid deployments. At the same time, the operations group is relying on certified stacks and frameworks, tuned to predefined environments and patterns. Operators can maintain a high level of security, and continue best practices for applications/systems monitoring and management. Moreover, faced with the challenges of delivering on service level agreements (SLAs) with the business units, operators can ensure performance, scalability, and reliability of the infrastructure. The elasticity of a cloud-computing environment – the ability to rapidly add virtual machines and storage in response to computing demands -- makes a difference for hardware utilization and efficiency. Contending with Continuous Change What does it take to succeed on the promise of the cloud? As the engine for innovation and productivity in the digital age, IT must face not only the technical transformations but also the organizational challenges of the cloud. Standardizing key technologies, resources, and services through cloud computing is only one part of the cloud journey. Managing relationships among multiple department and projects over time – developing the management, governance, and monitoring capabilities within IT – is an often unmentioned but all too important second part. In fact, IT must have the organizational agility to contend with continuous change. This is where a skilled consulting services partner can play a pivotal role as a trusted advisor in the successful adoption of cloud solutions. With a lifecycle services approach to delivering innovative business solutions, Oracle Consulting Services has expertise and a portfolio of services to help enterprise customers succeed on their cloud journeys as well as other converging mega trends .

  • Windows - Force Wi-Fi to N mode

    - by Frederick Marcoux
    I bought a month ago the D-Link DWA-160 Xtreme N Dual Band USB Adapter and I wonder about the speed. I have a 60Mbps but the speed is never above 300Kbps when I browse Internet or download something. Even from Microsoft or Apple (the fastest server I found). Now on Windows 8, we can see the Wi-Fi stats in Task Manager, there they are: Notice the red rectangle. The signal is 3/5 and I'm about 5 meters far from my router. An Apple Time-Capsule. Also, the connection type is 802.11g, I want N. I made this config in my Device Properties: Does anyone figured out to force the 802.11n in Windows? (Windows 8 preferably)

  • Formatting a disk for Macintosh using Linux

    - by Ken Bloom
    I've been asked to move data from an old external hard drive to a new one, and to make the new one compatible with the Macintosh. (The old drive's USB connection has died, and I'm connecting to old the drive using a PC card that provieds an eSATA to the drive. The recipient's Macintosh doesn't have a PC card slot, so she can't access the old drive anymore. Hence, the new drive.) Naturally, I'm doing this data transfer using Linux. I've discovered that I can format the drive as HFS+ using mkfs.hfsplus from the hfsprogs package. But I need to know: do I need to do anything special with the partition table? Is there a special Macintosh partition table format that I need to format this disk to? If so, what tools can I use to get the right format for the partition table?

  • SSH not working after Restoring Running-Config to a Replacement Cisco Router

    - by Kyle Brandt
    One of my Cisco routers died over the weekend, Cisco sent the replacement and I restored the the config using copy tftp: running-config. Everything seems to work fine but I can no longer ssh into the router (I can telnet). The connection is refused, so it isn't listening on port 22 it seems like. I had previously backed up the config by just doing ssh router 'show run' > backup_config from my workstation. So: Is there anything wrong with my method of backup vs copy running-config tftp:? I know I haven't given any debug information, but is there something typical I need to do to get ssh working?

  • Connect ADSL modem SMC7904WBRA-N to CISCO RV082

    - by Cy.
    I have a SMC7904WBRA-N ADSL modem/router that connects to the internet with a static IP given by the provider. I've received a RV082 to create a VPN connection which is having problems to connect to the remote VPN Server. After many tries we deduced that the SMC7904WBRA-N is being problematic with the NAT and I have been suggested to put the SMC router into the appropriate DSL bridging mode so the RV082 gets direct access to internet with the static IP. Can you give me any hints on how could this be done? Which mode is that?

  • Vmware Workstation Development Server on Laptop

    - by Koobz
    I'm running an Ubuntu guest OS on my Windows 7 laptop. Currently, I have it set up for bridged networking. The guest is os is configured for a static ip of 192.168.1.115, which depending on the network I'm connected to, may not be available. When I want to view my development work I hit that up in my web browser. I'm really looking for the following scenario: 1) My guest OS ip address stays constant. 2) I can access my guest os even if I don't have an internet connection, or a lan/router. 3) I can share files with my guest/host. How does one accomplish this using VMware Workstation?

  • Trouble Connecting to Virtual Machine after IP address Change

    - by David
    I have a VMware image running a copy of Fedora 11 which is hosted on a remote server. The remote server recently had its IP address change. I'm now unable to connect to my virtual machine. The server admin assures me that my virtual machine is running and assigned the new IP address. I have checked the firewalls and had the remote admin restart the VM instance. Neither of these fixed the problem. How do I troubleshoot a remote server which I am unable to SSH to? I'm actually even unable to ping the remote IP (connection timed out).

  • Confusion about git; how to undo?

    - by dan
    I wanted to install some source code that was on git. Don't really know what that means, I've never used git before, but I figured it was time to learn so, I first installed git. Next I tried to clone the git directory of the software I want to install. I got a message saying "the authenticity of can't be established". I went ahead and ended up with another message saying warning such and such will be added to known hosts. I went ahead and it said something about hanging up on the connection. After searching the internet for a while I realized I didn't need git to install the software but now I have it installed and have added some host to some file or another. I'm concerned I've created some security issues I need to fix. Can anyone help me undo what I've done, or better understand what I've done. Did adding a git project open up my system? Beyond that can anyone tell me how git works. Everything I've found assumes I know stuff that I don't yet. Thanks

  • Mod a Swing Arm Lamp into an Adjustable Camera Stand

    - by Jason Fitzpatrick
    If you’re looking for a simple way to get a bird’s eye view to record your DIY projects or other table-based activities like gaming or tinkering, this simple modification to a swing-arm lamp offers a highly flexible camera mount on the cheap. IKEAHacker reader Stef needed an adjustable arm for his iPhone camera so he could record in a top-down-view for some drawing tutorials he was working on. Rather than shell out big bucks for a custom boom arm, he scrounged up a swing arm lamp with a broken shade in the as-is bin at his local IKEA. To mount the iPhone he simply attached a car mount for the iPhone to the swing arm and called it good. Hit up the link below for more pictures; even if you don’t have an IKEA nearby, swing arm lamps are cheap and easy to acquire.

The plastic shelf for the copper prongs on the hard drive broke into the cable. Here is a picture of my handy work: Picture of damage I went to Best Buy Geek Squad to discuss my options and they said that they will need to send it to the recover center it could cost anywhere between $250 to $1600 USD to recover the data out the hard drive Is this reasonable for data recovery from a phyiscally damaged hard drive? Are there any other options I can explore? I am going to talk to the data doctors to see what my options are.

    I have a virtual machine with an internal IP address and a running mailserver with IMAP/POP3/SMTP. Everything works fine except: When I do an SSH tunnel to the guest server and want to connect to the mailserver with mail.*. then it does not work. There is a connection timeout. But If i connect to the internal IP 192.168..* then it works. So what can I do to enable the access from the domain name to the virtual machine with SSH tunneling?

  • Using curly braces with a standard pc keyboard on a mac laptop

    - by raoulsson
    I have a standard PC keyboard connection to my Mac laptop. All keys work fine but the special characters that need "Alt-Gr" as accelerator keys would not work. I have a Swiss layout where the curly braces are such special keys. However I need them all the time and having to get used to a different layout is too painful (I'd rather get used to a US Layout once and for all). Does anyone have an idea how to switch this? Note: I have managed to switch the option and the command key, so that's not my problem.

  • Significant OS X Finder lag when listing directories/files

    - by Jack Sleight
    I'm experiencing some significant OS X finder lag, that seems to be purely an issue with Finder itself, and not the HD or any other part of OS X (I'll explain below). The lag only appears to be when listing directories/files, where I'm seeing up to twelve or so seconds of lag (the folder opens with a blank list and the spinner going in the bottom right). This happens with both the local SSD and network drives (connected via ethernet or wifi) Browsing both local and network drives in terminal and listing directories is instant I can actually browse files on my NAS from my phone over a 3G connection from the other side of the country faster than Finder can when connected to the local network (madness!) Can anyone help? Thanks.

  • Raspberry Pi Now Shipping with 512MB RAM; Still Only $35

    - by Jason Fitzpatrick
    Fans of the tiny Raspberry Pi will be pleased to hear the new version of their Model B board now ships with 512MB of RAM (up from the previous 256MB). The best part about the upgrade? The price point stays at $35 a board. From the official Raspberry Pi blog: One of the most common suggestions we’ve heard since launch is that we should produce a more expensive “Model C” version of Raspberry Pi with extra RAM. This would be useful for people who want to use the Pi as a general-purpose computer, with multiple large applications running concurrently, and would enable some interesting embedded use cases (particularly using Java) which are slightly too heavyweight to fit comfortably in 256MB. The downside of this suggestion for us is that we’re very attached to $35 as our highest price point. With this in mind, we’re pleased to announce that from today all Model B Raspberry Pis will ship with 512MB of RAM as standard. If you have an outstanding order with either distributor, you will receive the upgraded device in place of the 256MB version you ordered. Units should start arriving in customers’ hands today, and we will be making a firmware upgrade available in the next couple of days to enable access to the additional memory. We’re excited to get our hands on a new board and try out Raspbmc with that extra RAM. HTG Explains: What is the Windows Page File and Should You Disable It?

  • getting Ubuntu-quality fonts / configuration under Cygwin/X

    - by user5402
    I have Cygwin/X installed on a Win7 box. I also have an Ubuntu VM running on the Win7 host. If I do the following: Start Xming on the Win7 box Start mate-terminal under Cygwin/X then mate-terminal starts up with very crappy-looking fonts and a blinking cursor. (I'm using "Monospace 10" in mate-terminal.) If I then do: Use putty to ssh into the Ubuntu VM (fowarding the X connection) Run gnome-settings-daemon on the Ubuntu VM then the fonts in mate-terminal suddenly become much better looking and the cursor stops blinking (probably because I've configured it that way in Ubuntu.) Question: How can I get the better-looking fonts and the ability to set cursor-blinks option for mate-terminal under Cygwin/X without having to run the Ubuntu VM? FWIW, I have Xming-fonts-7-5-0-4 installed. Update: Starting Xming with '-dpi 101' as suggested here helps, but the fonts are still not anti-aliased.

  • sql server log shipping

    - by voam
    I am setting up log shipping with two 2008 sql servers connecting with a vpn. As far as I know as long as the sql agent is able to access the share on the primary/secondary servers everything will work. When I set up the Log shipping on the primary server using SQL Mangagement Studio, before I can set any of the "Secondary Database Settings" it asks me to connect to the secondary server. But I really don't want to open up the connection to the secondary server. I will be initialing this secondary database with a backup so as long as the transaction logs get copies everything should work. How to I work around the GUI not enabling any of the settings for the secondary server until I actually connect to it? Thanks in advance!
