• Best suited multi-function printer for Linux usage from a few choices

  - by Nakedible

  I want a cheap multi-function printer for Linux usage. I'm looking for rock solid scanning and printing that works with big images. I'd prefer drivers that are available in Debian, or other drivers that are open source, but will settle for proprietary drivers if they are well contained and clean. Some choices I have are: Samsung SCX-4300 HP LaserJet M1120 MFP Samsung SCX-4500 Canon i-SENSYS MF4010 Brother DCP-7040 I am also interested in opinions what printer communication language is best for Linux usage for cheap printers. PostScript is nice, of course, but low-end PostScript printers often have problems when printing complex (large) PostScript files. It seems Samsung printers use SPL for communication, HP uses XQX and ZJS, then there's ofcourse PCL.

• Setup dhcpd without gateway on purpose

  - by MBober

  I have an XP machine with two network interfaces. One is connected to my company's network (and the Internet). The other is a very local network which connects some hardware with my PC. Both the hardware and my XP machine's second network interface obtain configuration from a dhcpd running on Ubuntu in a virtual machine on my XP machine. I entered some dummy gateway in /etc/dhcp3/dhcpd.conf like 192.168.3.1 which does not match any existing device just to get dhcpd started. The problem is that my XP machine now tries to route Internet traffic through 192.168.3.1 in most of the cases which, of course, results in an error. Is there any way to set up dhcpd in a way that the clients know that there is no gateway in this network? By the way: setting the gateway manually in XP is off the table because this needs administrator privileges which I don't have.

• I need a few minutes of dedicated server a week, but not for hosting, just to convert ogg etc.

  - by talkingnews

  I'm completely happy with my webhosting, it's just that I need to do one little thing they won't allow, and that's run an instance of Sox to convert about 30 mp3s to ogg files, in various directories, a couple of times a week, to be done automatically in response to the detection of the upload of an mp3. Probably looking at a minute of server time over the whole week. I've had unhelpful suggestions on other forums like "why not leave your home PC on 24 hours a day and then use all your isp bandwidth to do this", which doesn't work for me. I know that I can host files on, say, Amazon S3, but is there something similar for my needs? All it would need to do would be: wget/ftp the mp3 files, convert them to ogg, ftp the files back to my hosting. Of course, all this wouldn't be needed if there was such a thing as a compiled binary of Sox (or any mp3ogg converter) for Centos which I could upload without needing root access, but I've given up asking that one, but always open to suggestions!

• Good Documentation on Avaya IP Office 500 r2 setup

  - by Cliff Racer

  I have set up a couple of Avaya IP Office systems over the course of my current job. I have a pretty good handle on the process, but now I am faced with something I have not done before. Both the IP office systems I have set up used all Digital phones. The new system we are putting in place will actually use IP phones for the first time. After tyring to track down some general documentation on my own, I was not able to find anything that left me feeling comfortable about setting up IP phones on an Avaya IP Office 500. Does anyone know of any good how-To's for setting up IP phones on IP Office? I get the impression its pretty simple but learend enough about Avaya to know that there are some tricky aspects to setting them up

• firefox: getting access to the list of tabs/windows to restore on startup

  - by robb

  Sometimes ffox fails to restore the previously open tabs/windows. This might be happening when some of the urls to be opened are no longer reachable (e.g. behind a vpn) or after the underlying OS (Windows) has been forcibly restarted (e.g. to complete an automated patch installation). Anyway, after restarting, can this list of urls be recovered somehow? Say for example, I was daft enough to have clicked on "start new session". Can I still get access to the old list of open urls? There is the browser history of course, but it contains a lot of stuff - the urls that were open when ffox last exited are not obvious. It would be neat if they were marked in some way - tagged for example. .robb

• Anti-aliasing Japanese text on Windows 7?

  - by moonslug

  On most websites that display Japanese text, it does not appear anti-aliased in my browser, while Latin text of course does. Kanji is universially anti-aliased, which is somewhat understandable, but hiragana is not. This is only an issue on Windows - the Mac has much better & native font anti-aliasing which seems to work well regardless of the alphabet. Is there something on my end that I can do to fix this? And is there a way to ensure a website of my own creation displays anti-aliased Japanese text?

• How to configure bind9 to route to host's IP

  - by Greg

  I'm running apache and bind9 on the same server. I would like to set a master zone to route back to this very machine's IP address without explicitly specifying it. Is this possible? If I use 127.0.0.1 for the A record, then when another computer on the network does an nslookup for mydomain.local, bind of course just returns the loopback ip (127.0.0.1) -- not the IP of the server. Is there to way to tell it to just return the network IP address for the server itself, as defined in /etc/network/interfaces?

• How do I get the last value of a column in an Excel spreadsheet?

  - by Chris

  In column A, I have dates. In column B, I have my body weight logged for the day. I add one row to each every day when I weigh myself, so this means the data is sorted by date ascending. The weights, of course, fluctuate (though it would be nice if they would go down every day for my own personal benefit). For a couple of calculations, I want to get the latest (or last) weight entered in column B. Not the max or the min, but the last one entered in the column. I want it to work no many how many rows I enter. I use Excel 2007, if that ends up mattering.

• Wireless technology - which is better: more single radio APs or less dual radio APs?

  - by gert_78

  We are currently talking to vendors of wireless solutions for a wireless deployment in a university campus with some 5000 students. One vendor is offering us a Cisco solution with a WLC 5508 controller and 69 2x2 MIMO Dual-band/Dual radio APs (Aironet AP 1042 model) The other vendor is offering us an Aruba solution with a 3600 controller and 96 2x2 MIMO dual band BUT single radio APs (Aruba AP93) Both vendors are charging 82.000 US$ (support, 3y service contracts, switches and additional required options all included of course) The Aruba vendor is trying to convince me that 96 single radio APs will give us more connection/users/capacity then the 69 dual radio APs. I have my doubts about that and since it is my core competence-domain I wanted to ask here the opinion of people that have a more profound knowledge and experience in this area. When you talk to vendors it's often hard to get objective information. So try to answer only if you are sure and please mention it if you are affiliated with one of the vendors. I appreciate all useful help and want to thank you in advance for the effort!

• How to find out the reason why a scheduled task hang?

  - by Graviton

  I have scheduled quite a number of tasks in my Windows 7, doing a variety of cron jobs on my machines. I am perfectly sure that these tasks, when run on their own, won't hang. But the problem is that, when I run them daily, over the course of several days and weeks and months, occasionally some of them will hang. So I am forced to kill the hanged task and rerun it--- and now it can run successfully! I want to fix this problem once and for all, and for that, I need to know why a scheduled task will hang, even when I run it separately, it won't. Anyway for me to find out the reason?

• Bring OS X Error Message window to the front

  - by Debilski

  In OS X, when an application crashes, a window with an error report will appear. That window is by default unreachable by Command+Tab nor does it appear in the Dock. Of course, if by error or on purpose one clicks another window, the error report will go to the background and hide behind the other windows. This is really annoying, because in order to see it, I will have to use Exposé and scan through 20+ Windows in order to find it. (Not to say, that I don’t like Exposé anymore since Snow Leopard made the window sizes all confusingly equal.) Any ideas on how to make the error reports Command+Tabbable?

• Can Windows tell me what is using my USB drive?

  - by PP

  Being the good citizen I am, I left-click on the "Safely Remove Hardware" icon in my taskbar, and select my USB drive to dismount. Then I get the message: Windows can't stop your 'Generic volume device because it is in use. Close any programs or windows that might be using the device, and then try again later. Of course, being the Operating System, it knows exactly what applications are using my device. So why won't it tell me? As usual, I always end my Vista questions with this plea: anyone know a Microsoft Engineer I can kick?

• Adding a trigger command to autocomplete function in zsh

  - by mkaito

  When you define an alias like alias g=git, the shell will pick it up and run the corresponding autocomplete function. Now, there's a program out there called hub, which is basically a supserset of git, with some added, github-specific functionality. The recommended way to use hub is to alias git=hub. Of course, this won't trigger the autocomplete function for git, which makes sense. Now, if I wanted to have git's autocomplete trigger for hub, the only way I know of is editing /usr/share/zsh/functions/Completion/Unix/_git and adding hub in the first line as trigger. While this works, it isn't practical, since this file will get overwritten with the next zsh release. Assuming hub won't provide a zsh completion function any time soon, is there another way of adding hub to the trigger commands for git's autocomplete function?

• How to calculate time spent for Linux system administration?

  - by Jaakko

  I would love figuring out how much time I actually have spent in shell performing administrative duties. For billing of course, this information is not sufficient, but it would be helpful to figure out how much time I have actually spent in shell. My question is: How anyone got tips on how to calculate time spent in shell (in hours + minutes), let's say per user account? Could anyone recommend a software that could be used to analyze this time? Optionally I would like to know about ways how to categorise time spent (e.g. 1 hour for Apache, 2 hours for Samba, etc.) Also, your takes on how you monitor your admin time, are also much appreciated! To narrow down the problem, I am specifically interested in ways of tracking time spent in shell for Linux system administration

• Mouse button and keypress counter for Linux?

  - by rakete

  I would like to have some kind of statistic of my daily mouse/keyboard usage to help me make my keyboard layout a little bit more efficient. There is already an question about how to do this on windows, but I would like to know I anyone is aware if this is possible under linux. Another thing I already found is key-mon, a little program for screencasts that displays your mouse and keyboard presses on the screen, which would help me achieve what I want with a little bit of python coding by myself. But still, if there was an solution already, that would be easier of course. PS: obfuscated link to key-mon because of spam prevention: hxxp://code.google.com/p/key-mon/

• CheckPoint VPN-1 SecureClient inability to navigate behind a Linksys WAG300N

  - by user46819

  I have a Linksys WAG300N, I'm accessing my LAN with Wifi and everything works fine on my Windows 7 Enterprise laptop. When I try to connect to my company's VPN the connection succeeds, but I cannot access any internet site either within my work network or public site like Yahoo or Google. In my Linksys control panel I already verified all types of VPNs are enable to passthrough. Normal IPSec and Windows VPN worked in the past without any problems. CheckPoint seems to have a solution, but I do not have the ability to change the IP in my client and of course using another NAT device in between is not a solution for me. Edit: adding link to the Checkpoint solution, https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk26189

• How to check that image sizes are ok or not

  - by Goran

  I am having many image files in one folder. Mostly there are jpg, but some png, bmp, gif, tif also (but jpg is most important if others are not possible). There are also many xml files in same folder with same names as image files are having. So there is something like this: 1.jpg, 1.xml, a.png, a.xml, 3g.bmp, 3g.xml... All xml files are having only 1 line: <IMGRES WIDTH="1234" HEIGHT="567" /> (of course numbers are not same). I am looking for some easy way to check all image sizes and confirm if they are same as in xml or not. So I want output like: imagename, xmlwidth x xmlheight, realwidth x realheight, match/error Is this possible in only Windows with no other software installed?

• Disable mod_security on Dreamhost, for a single cgi script

  - by Hippyjim

  Hi I've searched around a lot, and tried various tweaks to .htaccess files to try to turn off mod_security for a particular cgi script (uber uploader) but it doesn't seem to have any effect. The most popular one I see rehashed all over the web is: # Turn off mod_security filtering. SecFilterEngine Off # The below probably isn't needed, # but better safe than sorry. SecFilterScanPOST Off Which looks relative simple to me - if "SecFilterEngine" is in some way related to mod_security of course. Shame it has absolutely no effect! Does anyone have a suggested way I can simply disable it for a request to any file in my cgi-bin directory?

• Juniper SRX1400 VPN

  - by ank

  I have been trying to set up a client VPN on a Juniper SRX1400 without much success. All documentation I found from Juniper and elsewhere does a lot of other (difficult and wonderful) things other than the simple things I want to do. We already have a VPN running on CISCO PIX hardware which we need to put to rest and we pretty much like to replicate the functionality, which is: 1) client makes a request to the outside interface of the SRX1400, 2) client gets authenticated, 3) if successful, then client is assigned all the usual DHCP stuff and becomes part of the network. What privileges this DHCP assigned network has, should be configurable of course with the usual routing/filtering methods. Am I asking for too much from the SRX for this kind of thing? Should I ditch the SRX for VPN and revert to an OpenVPN solution that I had working some time back also and was amazed at the ease of configuration, functionality and features?

• 503 service unavailable when debugging PHP script in Zend Studio

  - by user25932

  I have a web server with apache 2.0 installed. It comes with Zend Server install pack. When I’m trying to debug my php files apache serves a blank page with 503 service unavailable. Of course slow server-side code is tying up Apache requests for far too long, but I need it to wait, until my debugging comes to end. When I call to the page from a browser it launches ZendStudio debugging my PHP script (request redirects Zend Debugger module). I debug through my script and if I finish debugging in 120 seconds, I normally return to the browser. When it takes more than 120 seconds the browser displays '503 service unavailable' and I can't return to page output. I have even forced 'max_execution_time = 300' 'max_input_time = 600' in php.ini and 'TimeOut = 500' in httpd.conf. No matter whether it is Opera, IE or Firefox. I spent two days googling it, no right answer until now.

• How to increase the disk cache of Windows 7

  - by Mark Christiaens

  Under Windows 7 (64 bit), I'm reading through 9000 moderately sized files. In total, there is more than 200 MB of data. Using Java (JDK 1.6.21) I'm iterating over the files. The first 1400 or so go at full speed but then speed drops off to 4ms per file. It turns out that the main cost is incurred simply by opening the files. I'm opening the files using new FileInputStream (and of course closing them in time to avoid file leaks). After some investigating, I see that Windows' disk cache is using only 100 MB or so of RAM although I have 8 GiB available. I've tried increasing the cache size using the CacheSet tool but any values I provide are considered out of range. I've also tried enabling the LargeSystemCache registry key but (after rebooting) the CacheSet tool still indicates I'm using 100 MB of cache (and doesn't increase during the test run). Does anybody have any suggestions to "encourage" Windows 7 to cache my 9000 files?

• How do I clean a computer from dust?

  - by Jonas

  As computers become faster and generate more heat it gets more important to have good ventilation, but that also increases the amount of dust sticking to the components of the computer. It's of course better to make sure the computer never gets dusty by vacuum cleaning around it (not in it) frequently. But what to do if it's already to late? I've heard that vacuum cleaning the computer itself is very bad, since it can cause static electricity that hurts the computer. So, Does anyone have any tips for how to remove dust from your computer?

• SharePoint Server Search Not Crawling

  - by tekiegreg

  Hi there, we recently moved some sites into a new farm, everything seems to be doing fine, but the search for reasons I can't identify are not crawling the migrated content. We're getting this message in our crawl log for every document: http://xxx/sites/...announcements The object was not found. (The item was deleted because it was either not found or the crawler was denied access to it.) Of course the first thing I suspected was the crawler access account, so I logged into SharePoint with the account and was able to access via that URL just fine. I tried upping permissions (even all the way up to Admin) but to no avail. Thoughts?

• data replication from a production web server back to the staging web server

  - by Dennis Smith

  Have two web servers, development/staging and production. Code and some documentation is moved from the staging area to production either through on-demand jobs or nightly via a global replication job. The production server of course sits isolated in a DMZ. There is some content that gets uploaded to the live server that needs to be replicated back to staging. Our security team is locking the network down (and they should) and restricting access to the live server. Best suggestions for replication of "live" data back to "stage" and backing up the live server also.

• Why does Tomcat try to use the cache when compilation failed?

  - by etheros

  For some reason, it appears Tomcat is trying to hit its compilation cache when compilation failed. For example, if I create a JSP containing nothing but Hello, <%=world%>!, predictably, I get an error: org.apache.jasper.JasperException: Unable to compile class for JSP. Subsequent requests however alternate between this and org.apache.jasper.JasperException: org.apache.jasper.JasperException: Unable to load class for JSP. Further, if I create a JSP containing Hello!, it of course works just fine. If I modify it contain Hello, <%=name%>!, the response alternates between the previously-mentioned compilation error, and the cached Hello!. What's going on?
