• Installing SDM on a Cisco 2821 ISR

  - by Sam Sanders

  I trying to change the configuration of our router, it's a Cisco 2821 Integrated Services Router. I don't know much about Cisco products. While looking at the PDF manual for the router I notices it talked about SDM Security Device Manager. But when I point my web browser at the IP address of the router, it give me a very simple web interface. It's sort of like a string builder for CLI commands. I'm guessing SDM was not installed on it. So my question how would I go about do that? I found this link (below), but I'm a bit new to networking. So any advice would be welcome. http://www.cisco.com/en/US/docs/routers/access/cisco_router_and_security_device_manager/software/quick/guide/SDMq7.html

• dead man's switch for remote networking interventions

  - by ascobol

  Hi, As I'm going to change the network configuration of a remote server, I was thinking of some security mechanisms to protect me from accidentally loosing control on the server. The level-0 protection I'm using is a scheduled system reboot: # at now+x minutes > reboot > ctrl+D where x is the delay before reboot. While this works relatevly well for very simple tasks like playing with iptables this method has at least two drawbacks: It's not very reactive, ie a connectivity problem should be detected automatically if for example an automatic remote ssh command fails does not work anymore for x seconds. It can obviously not work if one need to modify some configuration files and then reboot to test the changes. Are you guys using some tool for the second point ? I would love to have something able to revert the system configuration in a previously known stable state if I can't join the server X minutes after reboot. Thanks!

• Sync iPhone Mail with Webmail

  - by João Paulin

  I had an email account [email protected] hosted on Host A. This mailbox had 100 messages. I wanted to migrate to Host B, so I download all the 100 messages from Host A on my iPhone. Now that my site was successfully migrated to Host B and the email account [email protected] was created again (the mailbox is empty), how can I send the messages that I have downloaded on my iPhone to the mailbox on Host B? Note that the migration from Host A to Host B did not change the IMAP and SMTP adressess and parameters. I'm still using the same addresses, parameters and ports as before. The email accounts just switched hosting.

• When DNS doesn't cache

  - by John Francis

  We've had some odd DNS problems over the past couple of days that I don't fully understand. Some of our DNS names stopped resolving for some of our customers due to some 'unknown' server reconfiguration at our DNS provider. The problem seemed to be intermittent i.e. stopped working and started working within a few minutes over a couple of days. I'm no expert on DNS, but I'd have expected DNS caches to prevent this sort of thing from happening - when we need to change an IP address for a DNS record, it can take 24 hours to propogate, so how can our DNS provider be breaking name resolution intermittently for our customers so easily? Shouldn't the DNS caches kick in here? We had a similar problem about a month ago when one of their nameservers 'decided to reload the DNS database from scratch' - this broke our name resolution too. Again, why didn't the caches satisfy the name resolution requests. Any guesses would be appreciated. John

• xDebug on Zend Server CE under Windows XP

  - by Hippyjim

  I have Zend Server installed on my Windows XP development machine, installed when I was naive and didn't know that Eclipse was going to become so suck so badly for PHP development. I've made the upgrade to Netbeans, but for debugging they only support xDebug. To be fair I've never used "proper" debuggers before, but other folks have raved about them so I thought I'd give it a try. I followed some directions on the Zend forum about how to install xDebug on Zend server, disabling Zend Debugger in the process. The xDebug "custom installation instructions" wizard tells me that my PHP was compiled with an unsupported compiler (MS VC8), and won't let me download anything. I tried a couple of the other xDebug binaries, but they just refused to load. So I'm left without a debugger option. Does anyone know how I can change the compiler of the php version I have installed so I can use a debugger in Netbeans? or how else i can get xDebug to install on Zend Server?

• Test disk recovery

  - by AIB

  I had a 250GB hard disk having several NTFS partitions. The disk was a dynamic disk (created in windows). Now when I formatted windows (which was in another disk), the dynamic disk is shown as offline. I tried using the testdisk tool to recover the data and created a partial backup. Testdisk is able to list all partitions in the disk. All partitions are shown as type 'D' (Deleted). I want to change the 'D' to 'P' (Primary), 'L'(Logical), 'E' (Extended) appropriately and build a new partition table. If I can write the partition table to disk, the disk will be of 'basic' type and should be readable in all OS. What should be the appropriate partition types? I checked the files on the partitions and no OS was ound. So none of the partitions were bootable. Will randomly selecting P,L,E hurt the data in anyway?

• Use an unsigned driver in Windows 7 x64

  - by rjmunro

  I'm trying to use the RBC9 SpaceNavigator TEST x64 build drivers for my SpaceNavigator 3d joystick so that it can work as a normal joystick in games like Quake. Unfortunately, I get the error "This version of windows requires all drivers to have a valid digital signature" and in the "Device status" in device manager, I get "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)". Is there a way to work around this issue?

• Divide bootloader from dualboot with Windows 7 and Windows XP

  - by manwithproblem

  My problem is the following: I have a dual boot running on my pc. I installed a programme called "Keriver", it automatically installs GRUB, too. When I start my PC, the first thing you see is GRUB. You can choose between "Boot normal" "Take snapshot with Keriver" "Boot Windows" If you select "Windows" or "Boot normal" it calls the Windows 7 Bootloader and it again shows a menu, where you can choose between XP and Win 7. Unfortunately for me, Microsoft does this "mixing bootloaders into one" automatically. I don't know how to change that now, how to separate them. I'd like to start everything directly from the GRUB menu. The bootloader is stored on hd(0,1). I tried to boot from hd(0,0) and hd(0,2) as well, but it didnt work. Can anyone help me please?

• How to have file/folder icons use a relative path?

  - by Memor-X

  On my portable hard drive I set icons for almost every organized folder. All these icons are located in an Icons folder located on the root directory of the same hard drive. When I change the drive letter of the hard drive (well I don't, windows does automatically sometimes) these icons are lost. So far this hard drive is assigned to F: While it's not a problem now, it may becomes a problem if I upgrade my computer or get a new one and the F: Drive is already taken up for something else. It's also annoying on networks where F: is mapped to a network drive.

• How to prevent laptop screen brightness from changing when un/plugging battery power

  - by Nomad

  When I am using my laptop, I continually adjust the screen's brightness based on the lighting conditions in the room (e.g. how much light is coming in from windows, etc.). But if I unplug the laptop or plug it back in, Windows looks at the default brightness setting in the power profile for "on battery" or "plugged in" and changes the brightness accordingly. This is a jarring experience and then I have to hunt down the ideal brightness for my current situation again, rather than getting on with my work. I would like to make it so that plugging or unplugging the battery is not a trigger that adjusts the screen brightness at all. The screen brightness should only change when I adjust it myself. Does anybody know how this might be accomplished?

• Is it possible to use Logmein to connect to a sleeping (Mac) computer on a wireless network?

  - by jaydles

  I'm using logmein to access my Mac. So I have the local logmein app running on my MacBook Pro, which is on my home wireless network. I access it either from the website (www.logmein.com) or the Logmein Ignition Apps on the iphone or ipad. My problem is that I have to set my MacBook Pro to not sleep at all when plugged in to make this a practical solution, because logmein cant seem to wake it up. I did change the settings in System Preferences to allow "Wake from Lan", but it seems like this won't work with a a Wifi connection. Am I missing anything? Assuming I'm not, is it bad for my computer to basically leave it running and not asleep most of the time?

• Join performance on MyISAM and InnoDB tables

  - by j0nes

  I am thinking about converting some tables from MyISAM to InnoDB in my mysql server. The tables will certainly benefit from the change because a lot of write requests come to these tables, while there are also quite a lot of read request at the same time. However, they are often joined together with some tables that almost don't get any writes. Is there a performance penalty when joining together MyISAM and InnoDB tables or should everything work fine? Second question: During backups at night, I am copying data from the InnoDB tables to MyISAM tables for archiving purposes. In these backups, a lot of write-requests happen, however there is almost no read from these archive tables. Would these tables also benefit from using InnoDB or is this just a waste of space and RAM?

• Changing default shortcut for Spaces on a Macbook Pro with Snow Leapord?

  - by Mahmoud Abdelkader

  I'm primarily a Linux user but my main home PC is a Macbook Pro with Snow Leopard. The concept of "Spaces" in a Mac is extremely important to how I utilize my development environments and I use this feature on Linux all the time. I use Compiz Manager for Ubuntu which allows me to "Desktop Switch" and navigate all desktops using the Ctrl+Alt+Arrow keys to a particular desktop. On a Mac, the process is similar, however, you're only given 3 non-customizable short-cuts: Option+Arrow, Ctrl+Arrow, and Alt+Arrow. How can I change the keyboard shortcut to take Ctrl+Option? The keys would then fit my working style and it won't feel awkward to remember two sets of keyboard shortcuts. Thanks! Mahmoud

• White Screen of Death

  - by cust0s

  The other night I updated my iTunes to the latest version (through Software Update) when I came to turn on my computer I was greeted with the dreaded white screen of death. I use an early 2008 iMac 24". I've tried the basic things, unplugging/turning off accessories, trying to boot from the install disk, reseting pram, etc, etc. Still no luck and no change what-so-ever. All I've been able to ascertain that my keyboard still works (by ejecting). I should point out that I did recently replace my Hard drive with a Western Digital Black 500GB (though the computer is well out of warrenty) and I'm a little concerned that the problem could be the screen.

• Eclipse And Linux: Keyboard unusable after gnome-screen-saver

  - by martijn-courteaux

  Hi, I know this is not programming related. But I can't find any topics on Google or UbuntuForums. So the problem is: When gnome-screensaver starts on the moment Eclipse has the focus and I wake up again my laptop, Eclipse doesn't listen to keyboard-events. To solve this I have to change the focus to another program and then back to Eclipse. Than it works again. This isn't a real problem, but it would be nice if someone can solve it. Thanks

• Can I make Terminal.app open different profiles with shortcut like iTerm?

  - by Patrick

  I've been using iTerm for a while, but I switched back to Terminal.app in Snow Leopard due to the Visor plugin. Most of thing works pretty well after I switched to Terminal.app, except in iTerm, I can create different profiles and assign each profile with key shortcut. The advantage of this setup is that I can have non-transparency and transparency profile. If I need to look up a command on the background, I can start a transparency shell, and vice versa. I was thinking to use Mac built-in "Application shortcut" in System preference. Though, I realize in Terminal.app, the "New Window" and "New Tab" have the same profile names, so the Application shortcut is confused and I can't assign a shortcut to it... Any thought on how to change menu name on Terminal (or even better, any application?) Thanks for your help.

• Wikimedia Commons not working properly from IE 8

  - by Johannes Rössel

  It happens fairly often that a page on Wikimedia Commons doesn't load in IE. This happens to me on both machines I use, each one Windows 7 with IE 8. The page just loads endlessly (or connects—can't really tell) and timeouts after a while. Repeated attempts (trying to load the same page in 5 to 10 tabs) sometimes work, but sometimes it takes a lot more tries. As far as I can tell, no other program is affected—Firefox or PowerShell have no trouble loading the page. Also, when I use Fiddler it seems to load fine on the first try as well. Anyone has an idea what might be going on? I didn't change any settings that I am aware of (and most likely didn't do so in the same way on both machines). Preemptive note: I don't need advice in the form of »Use another browser instead.«.

• forwarding port 3306 on macosx in order to connect to a remote mysql db

  - by Jonathan Mayhak

  I'm on macosx 10.6.2 trying to connect to ubuntu server 8.04.1 at linode. ssh -L 127.0.0.1:3306:[[remote ip]]:3306 user@server -N I want to set up ssh tunneling so that I can access a remote mysql server. First of all, I'm told bind: Address already in use. This is only after I've tried the command before. How do I manually close a port forwarding session? Second, when I change the command to be ssh -L 127.0.0.1:3310:[[remote ip]]:3306 user@server -N (I changed the local port to listen on). I'm told channel 1: open failed: connect failed: Connection refused when I try to connect to the mysql server via mysql workbench or sequel pro. To connect through mysql workbench I use the following settings: host: 127.0.0.1 port: 3310 (if 3306 is in use) username: mysql username password: mysql password database: I don't put anything in

• (simple) linux HA with vmware vsphere?

  - by derhelge

  I hope my upcoming question is specific enough, and you are able and willing to support :-) We have several openSUSE VMs in an ESX-Cluster (three ESX-Servers) with an attached iSCSI-SAN. All of those Linux VMs are "single point of failure"-configured, which means in the case of a Web-Server: LAMP, storage, etc. everything on this machine. This was very simple and in case of a failure (in the last years: kernel panics or apache crashes) a simple reboot triggered by a script did it. But the problem is: How to upgrade/maintain the w(eb-)application or the underlying OS without downtime? This wasn't really managable and i did this in the early morning ;) How can i achieve a "simple" High-Availability Cluster now? I thought of: DRBD with heartbeat with 2 VMs. And for the storage a RDM (raw device mapped) LUN and change the read-write-permissions for both VMs. Is this a good idea? Anyone has a better solution?

  My CentOS 5.6 server's hostname was "centos" . And then i change it to my domain : hostname domain.com And i started to installing WHM / cPanel as explained in here : http://etwiki.cpanel.net/twiki/bin/view/AllDocumentation/InstallationGuide/InstallingCpanel It's installed very well.

• How to edit CSV file without changing or formatting values (ideally in Neo/Open-Office)?

  - by Scott Saunders

  I often need to edit CSV files that will later be imported into databases. I need to reorder columns, change values, delete lines, etc. I use NeoOffice for this now - it's basically Open Office with some Mac UI stuff tweaked. Often, though NeoOffice tries to be "helpful" and reformats fields it thinks are dates, rounds numbers to some number of decimals, etc. This breaks the file import and/or changes important data values. How can I prevent this from happening? I need to edit the fields exactly as they would appear in a text editor, with absolutely no changes to the data in the fields.

• Multi screens are not aligning properly

  - by Steve

  I am using (4) Samsung (SMB2230) screens. When I place my mouse on the first screen at the bottom right and pull it into the second screen the mouse jumps to the middle on the left of the second screen. Then it does the same on the 3rd and 4th screens. The biggest jump is between the 1st and 2nd then it tightens up between 2 and 3 then close between 3 and 4. This is a really pain because my mouse gets hung up and I have to move up and down to get it to change screens.I had (4) Dells screens before and this didn't happen. I'm using Windows 7

• Find running processes created by Mac Automator

  - by zechdc

  Is there any way to view automator process that are running? About a year ago I created a workflow or something similar in Mac's Automator. When I took screenshots mac would place them on the desktop. I created a small script to take move those screenshots to a different folder. I want to change what folder those are saved in now. Problem is, I can't figure out how to edit my workflow. The biggest problem, I don't know where the workflow/file is stored. The process is always running so anytime I take a screenshot it is moved. Is there any way to view automator process that are running? Also, I know there are other ways to make screenshots appear in different folders. I still want to find this process/script and kill it =) Any suggestions are greatly appreciated. Thanks.
