• DHCPOFFER delay VLAN

  - by john883

  I have configured two VLANs [ 15 and 16 ] and a trunkport on a Cisco Catalyst 2960. The trunkport is connected to eth2 on a Linux server The server is configured to support VLAN's and the interfaces eth2.15 eth2.16 is configured with ip addresses on two different subnet. dhcp3-server is running on the same server and hands out IP-addresses to the VLANs. When connecting a client to a port that is configured in ex. VLAN 15 and requesting a IP-address, i experience a long delay before recieving a DHCPOFFER, around 30 seconds or so, the client needs to send a DHCPDISCOVER about five times but will always recieve a DHCPOFFER. Any suggestion why this delay is happening?

• Is it illegal to download (from torrents) software that you have already legally bought?

  - by joshhunt

  With Snow Leopard now out, I decided to order myself a copy. But as I bought it online, it takes six to eight weeks three to five days for to to arrive via snail mail, but I want it now. Seeing that I have already legally bought a license for Snow Leopard, can I download a retail version of Snow Leopard from a torrent, without breaking the law? I understand that the law varies from country to country, so I acknowledge that this may be a tough question to answer sufficiently. I am in Australia, so I suppose I am mostly interested in answeres regarding Australian law, but other counties (or a general response) are also fine NOTE: SuperUser is NOT a legal resource and any advice/answers here should NOT be used as legal advice in any way.

• Upgrading Fedora 16 to 17 with crypted LVM

  - by nijansen

  As the title suggests, I want to upgrade Fedora 16 to the Fedora 17 Alpha build, but I am struggling to do so because of my crypted HDD. To avoid the hustle of CD-ROM or USB install, I thought the preupgrade would be a good idea. It downloads the stuff, stores an image somewhere and creates an entry in my boot manager. When I choose to upgrade from the boot manager it crashes halfway through because it can not access any of the prepared files (because it's crypted) and hands me a debug console. Unfortunately, this case apparently is not covered by the Fedora troubleshooting advice, at least I was not able to find anything there. I would guess I have to mount my HDD manually, but 1) how? and 2) how do I resume the upgrade afterwards? I would really appreciate a push in the right direction.

• IBM x3620 Server takes a long time to boot past UEFI to OS

  - by Joel Coel

  I have a pair of IBM System x3620 servers. These servers do fine once they finally reach the point where the operating system takes over, but it takes them forever to get past the new-fangled UEFI boot system... a good five minutes or so; maybe longer. I haven't timed it, but it's the kind of thing where you go get a cup of coffee while you wait and it's still going when you come back. Normally the only time I shut these down is for a monthly maintenance cycle (usually just windows updates), and so it's not a big deal. But in the case where I might have an outage I'd sure like to get that 5 minutes back. Is there anything I can do to tell them to just go ahead and boot already?

• Best labeler for the server room?

  - by Matt Simmons

  Right now, I've got a Brother P-touch labeler that prints four or five sizes of text on one long label. It has features such as italics and bold. It's...non-ideal. What do you use in your server room? I have heard of labelers that will print vertically as well as horizontally, or which can produce labels for cable management as well. I also think it would be great to be able to produce barcodes for my tapes (LTO-3). So basically, I would like a labeler that prints normal, can print cable labels, and can print barcodes. Unicorn optional. Any ideas, or could you even suggest the best labeler for each solution?

• Keyboard causing freezes

  - by fluteflute

  My problem started on Windows XP: a computer (that was working fine for many years) had a problem, that I can't quite remember (may have been to do with the startup process) - but I solved it by swapping the keyboard with one on another machine. Now for several years the problematic keyboard has been working fine - on my main machine that runs Ubuntu. I also dual boot Windows XP - and have had no problems on either OS. However I recently installed Ubuntu 11.04 Natty (pre-alpha) and found that any keyboard press causes freezes. (All still works fine on Ubuntu 10.10 and 10.04 and Windows XP) Just wondering why I might be experiencing this? Seems strange to me that's its not consistent.

• Can a power failure or forceful shutdown damage hardware?

  - by Vilx-

  Can computer hardware suffer damage from forceful shutdowns (holding the power button for five (5) seconds) or power failures? I believe that normal PC hardware does not suffer from this - after all, it's not much different than what they experience under a standard shutdown. But elsewhere I've read tht another person thought that it could do physical harm to the hard drive and possibly other components as well. He also said that the journaling features of filesystems are useless in face of power failures and were intended to help mitigate damage from system crashes. I think this is nonsense, but then again I lack the experience and knowledge to say it with certainty.

• Two different page numbers in Word 2007 (one starting at 1, the other at VI)

  - by user1251007

  I have a document (docA) with arabic page numbers in the header. Now docA is part of a thesis which has roman numbers in the footer. So I want to add roman page numbers to docA. This is no problem. But now I want to adjust the numbering of the roman numbers (as the thesis has lets say five pages). This is what I want: arabic page numbers in the header, starting at 1 roman page numbers in the footer, starting at VI I tried this: I choosed 'Page Number', 'Page Number Format' and tried to adjust the starting point. However, this changes both page numbers. How is it possible to have different numbering in the header and in the footer?

• What are those white circles on the desktop in Gnome 3?

  - by monk

  I have Fedora 20 with GNOME 3.10.2. On the desktop background (i.e. where the wallpaper is), there are five small white circles centered at the very bottom of the screen. The first is filled, the others are not. I can click those circles, thereby changing which one is filled, like a radio button. I cannot for the life of me figure out what those circles are supposed to do, and it's starting to drive me crazy. Clicking and thus changing which circle is filled does nothing I can perceive, and there seems to be no configuration option anywhere that has anything to do with them. What are those things? Is there any way to get rid of them? Edit: I made a screenshot of my desktop with no programs running. You can see the dot/circle thingies at the bottom.

• Top ten security tips for non-technical users

  - by Justin

  I'm giving a presentation later this week to the staff at the company where I work. The goal of the presentation is to serve as a refresher/remidner of good practices that can help keep our network secure. The audience is made up of both programmers and non-technical staff, so the presentation is geared for non-technical users. I want part of this presentation to be a top list of "tips". The list needs to be short (to encourage memory) and be specific and relevant to the user. I have the following five items so far: Never open an attachment you didn't expect Only download software from a trusted source, like download.com Do not distribute passwords when requested via phone or email Be wary of social engineering Do not store sensitive data on an FTP server I have two questions: Do you suggest any additional items? Do you suggest any changes to existing items?

• Inexpensive degaussers or HDD shredders?

  - by Nicholas Knight

  I do a lot of work for a small cash-strapped business that has a lot of active hard drives, most are consumer-grade SATA of about five years of age, and predictably they are dying at an increasing rate, and a lot of the time they can't even be detected, let alone complete a zero-out cycle. Right now those drives are just being stored, but that can't continue forever. We've got a couple bad LTO tapes it'd be nice to deal with, too. There are very real security and legal issues that make dropping them off with someone who claims they'll be properly destroyed a gamble. I've looked around at degaussers and HDD shredders, and the ones that don't look like they come from some guy in his basement all seem to be $3000+, which is hard to swallow right now. Is there anything out there in the $500-1500 range that you would recommend? (Speed isn't a big issue, if it takes several minutes or even hours per drive, that's completely OK, we've only got 10 or so thus far.)

• Vista - perform scheduled actions only if screen is not locked

  - by Syntax Error

  Ok, here's the general idea of what I want to do. After a certain time, I would like the computer to nag me to go to sleep. Maybe every five minutes or so. But I don't want the messages to pop up if the screen is locked, because I leave it like that all night. Ideally I would like to be able to do more things like shut down running instances the web browser, or lock my user session if I ignore the notices for too long. But I'm happy with just popup messages if that's all I can do. So, how much of this is possible and where do I start? I'm not too well versed with task scheduler, and I'm assuming I'll use that to at least start whatever script I have to put together.

• Hide Drive / Avoid Low Diskspace Warning on ReadyBoost Cache?

  - by Simon Richter

  I've just added an SSD as a ReadyBoost cache drive, and have two minor cosmetic issues with it: the drive still shows up in the drive list I get a warning balloon every five minutes that the drive is full and that I should empty the Recycle Bin. The former is ignorable (and I guess I can solve it with a group policy); the latter is somewhat going on my nerves. Are there official buttons "hide ReadyBoost drives" and "do not warn on low diskspace for ReadyBoost drives" somewhere that I may have missed? If not, I guess I can use the group policy to hide the drive; I'd still need a way for the system to not warn about the drive being full. Also, am I right that I need to assign a drive letter and format the drive with NTFS to use it for ReadyBoost, or is there a way to just use the raw device?

• Mac OSX snow leapord move to folder on keystroke

  - by Georges Oates Larsen

  On a weekly basis I have to organize thousands of photos (in groups of up to five thousand) into folders depending upon what they contain (to then narrow them down to the best photos of the same thing). This means I am constantly scanning through photos and organizing them into a folder. THe problem is, the process of stopping my scan, then dragging the photo all the way into a folder myself is bogging me down. Would it be possible to, for instance using something like applescript, or even going so far as using XCode/Cocoa, to create a shortcut that moves whatever I have selected in the finder to a pre-specified folder? Does somethign like this already exist?

• Cron Script to Delete Folder Contents Every 5 Minutes on Media Temple

  - by Brian Iannone

  I'm not familiar with server-side scripting, but I'm currently using a PHP application on Media Temple to cache JPEGs from four webcams hosted on a server located in the middle of the Indian Ocean. (Hence my reason for caching them in the US.) The webcams are updated every five minutes. The PHP application stores the cached images in http://static.rigic.co/cache/. I would like to create a cron script to automatically delete the contents of "cache" (not the folder itself; just the files inside) at a regular interval.

• Is is possible to hide label colors in list view in Mac OS 10.X Finder? I use labels as star ratings

  - by Andrew Swift

  I have modified the first five label names in OS X Lion to be ? through ?????. This way I can easily tag photos etc. in the finder. However, I find that Apple's rendering of the colored bars is horrendously ugly. I'd like to keep the labels (to be able to sort by label) but not see the colors. I know it was possible to change the colors with Label X, but Unsanity has not issued an update for Lion. I don't need to change the colors, just find a way to hide them in the finder.

• What kind of eye wear can I use to protect my eyes from staring at a screen all day?

  - by dr dork

  Many of us stare at computer screens all day. Lately, my eyes have been irritated from prolonged staring at my computer screens. Does anyone use or know of any eye wear technology that helps with this? About five years back, I bought a pair of prescription-1 eye glasses that had a no-glare layer put on them. It slightly helped, so I'm considering getting another pair. Is this the best option I have at this point? Thanks so much in advance for your wisdom!

About five years back, I bought a pair of non-prescription eye glasses that had a no-glare layer put on them by an optometrist. It slightly helped, so I'm considering getting another pair.

• Server suddenly running out of entropy

  - by Creshal

  Since a reboot yesterday, one of our virtual servers (Debian Lenny, virtualized with Xen) is constantly running out of entropy, leading to timeouts etc. when trying to connect over SSH / TLS-enabled protocols. Is there any way to check which process(es) is(/are) eating up all the entropy? Edit: What I tried: Adding additional entropy sources: time_entropyd, rng-tools feeding urandom back into random, pseudorandom file accesses – netted about 1 MiB additional entropy per second, problems still persisted Checking for unusual activity via lsof, netstat and tcpdump – nothing. No noticeable load or anything Stopping daemons, restarting permanent sessions, rebooting the entire VM – no change in behaviour What in the end worked: Waiting. Since about yesterday noon, there are no connection problems anymore. Entropy is still somewhat low (128 Bytes peak), but TLS/SSH sessions have no noticeable delay anymore. I'm slowly switching our clients back to TLS (all five of them!), but I don't expect any change in behavior now.

• My MacBook Pro (2011) is dead

  - by Dave

  I connected my Sony digital camera with the MacBook and the screen turned black. I wonder why because the Sony camera was not on at the time and technically could not be accessed. So I thought it might be temporary and I turned on my camera. Well, it did not work, but my MacBook Pro has been dead since then. It will not turn on - when I hold the power button for five seconds, nothing happens. When I connect the charger cable, the green light is very dim and blinks a little (with about 20% illumination). I wonder what the problem is. I have to call Apple Care, but just so that I know, what could be wrong? Is my MacBook permanently dead? It might be under warranty but I am not sure.

• Colors less saturated in Snow Leopard Finder, Preview & Safari than in Chrome -- why?

  - by Andrew Swift

  If I look at the picture here in Safari, Preview or the finder, the shades of blue are significantly different than if I look at the picture in Google Chrome (they are less saturated than in Chrome). Since I am a photographer and need to prepare pictures for publication online, I need to know what a jpeg should really look like, in order to color-correct it. I have an excellent Eizo monitor that is correctly calibrated. If I open the same image in Photoshop CS3, I get the Chrome colors if I use Monitor RGB under view proof setup, and I get the Safari colors if I use Macintosh RGB. Can anyone explain the difference between these two settings, and the difference between Safari and Chrome? Which colors are correct? Photos that I prepared under Windows (during the past five years) now seem washed out in the Apple Finder and Preview, even though I had correctly prepared them. Is there a setting on the Macintosh for color calibration, besides the monitor calibration control panel?

• VMware ESX 3.5 Host Health shown as unknown

  - by dunxd

  I have an ESX 3.5 update 5 cluster of five host servers, all fully patched as of this Friday. Today I noticed that one of the servers has the Hardware Health status as unknown in Virtual Center Infrastructure Client. When I look at the Health Status view under configuration for that host, all the items are status Unknown. The server is exactly the same configuration as the others - same model (HP DL360 G5), memory, NICs etc. I have tried restarting the management service with service mgmt-vmware restart but this has not resolved the issue. Asides from this, I am not seeing any issues with the cluster - however, I hate having a blind spot like this. Any ideas?

• Mini-jack problem with Sony Vaio (running XP)

  - by qftme

  I have a five year old Sony Vaio laptop (vgn-fw31m) that has had impact damage to the audio-output mini-jack for about the last year or so. In a recent discussion with my brother, we wondered whether it would be possible to write a program that would enable windows to use the microphone mini-jack input as the audio-output? As I currently use this laptop for work I am not keen to risk pulling it apart in order to replace the components comprising the audio-out. I therefore 'hope' that a programming solution exists. I would really appreciate any advice on this and eagerly await your response. Kind regards, qftme :)

• Web Filter For Multiple Networks

  - by Rob

  I have been using a Barracuda web filter 310 in our network and I have just had enough of it. It does not support trunking and we have several networks that have users that need to be web filtered. (I guess if everyone just did their flippin jobs I would not have this issue) but the management wants me to get it resolved. Does anyone know the top five web filters that are better than the barracuda web filters that support network trunking so that I can have multiple domains and subnets going through it? Thanks in advance - everyone on this site is gold in my book!

• How much power supply do I need for my server, and could a shortage be causing my odd crashing?

  - by dolan

  I have 5 servers, all with similar hardware (i7, four 2tb 7200rpm drives, two 4tb 5400rpm drives, 430 watt power supply), and lately the machines have been freezing up. This has gotten worse in the last day or so, and I can't pinpoint any explanation. One recent change was adding the two 4tb hard drives. The crashes happen most often while running a large Hadoop job, so I was originally thinking the load was causing some issues, but last night one server just froze without any heavy load on the box (or so I think), other than HDFS (Hadoop's distributed file system) was probably rebalancing itself since two of the five nodes were offline. If I plugin a monitor and keyboard to one of these frozen machines, I can't get any response or feedback on the screen. Any ideas on possible points of failure and/or different logs I can look at to investigate? Thanks Edit: The systems are running Ubuntu 10.04 Edit 2: More on hardware: intel core i7-930 bloomfield 2.8ghz processor (quad core) 12gb (6 x 2gb) kingston ddr3 1333 ram antec earthwatts green 430 power supply msi x58m lga 1366 motherboard
