• Cannot run SSH or send commands to /etc/init.d/ssh

  - by ThinkBohemian

  When I attempt to execute any commands such as /etc/init.d/ssh restart or /etc/init.d/ssh start, I get no output. It just goes to the next command line (Ubuntu Hardy). I can even pass in junk parameters such as /etc/init.d/ssh asldkfjalskfdj and i get no warnings or error messages, it just goes to the next line. I can check in my processes: lsof -i :22 and don't see my ssh process. I also don't see my SSH process when i run: netstat -na --inet Any troubleshooting suggestions?

• Oracle Enterprise Manager Logs

  - by idea_

  Hi, I'm attempting to investigate the root cause of the following error which occurs each time a users call an Oracle 10g Forms applet: FRM-92102: A network error has occurred. The Forms Client has attempted to reestablish its connection to the Server 1 time(s) without success. Please check the network connection and try again later. Details... Java Exception: java.io.IOException: Connection failure with 503 This error remained after restarting all my system components: HTTP_Server, OC4J_BI_Forms, Web Cache, Reports Server, etc. The only way to clear this issue was to restart the server entirely. During the downtime, web pages were rendered with the PL/SQL cartridge and being served, so it appears as though this was isolated to forms. Does anybody know which log files may provide clues here? Any help would be much appreciated :) Update: If somebody can provide me with a way or reference to increase the capacity of my web server to minimize these errors, I will accept this as the solution.

• Securely wiping a file on a tmpfs

  - by Nanzikambe

  I have a script that decrypts some data to a tmpfs, the directory is secure (permissions), the machine's swap is encrypted (random key on boot) and when the script is done it does a 35 pass wipe (Peter Gutmann) of the cleartext on the tmpfs . I do this because I'm aware wiping files on a journaling file system is insecure, data may be recovered. For discussion, here're the relevant bits extracted: # make the tmpfs mkdir /mnt/tmpfs chmod 0700 /mnt/tmpfs mount -t tmpfs -o size=1M tmpfs /mnt/tmpfs cd /mnt/tmpfs # decrypt the data gpg -o - <crypted_input_file> | \ tar -xjpf - # do processing stuff # wipe contents find . -type f -exec bcwipe -I {} ';' # nuke the tmpfs cd .. umount -f /mnt/tmpfs rm -fR /mnt/tmpfs So, my question, assuming for the moment that nobody is able to read the cleartext in the tmpfs while it exists (I use umask to set cleartext to 0600), is there any way any trace of the cleartext could remain either in memory or on disk after the snippet above completes?

• How to gain admin privileges on D-Link router if my isp is not allowing me to do so?

  - by Fischer

  So I switched to new ISP yesterday, they gave me a D-Link router, can't use my old router. I want to change the wireless password, went to 192.168.1.1, I can login with the the username and password user user, but not as admin. On the catalog it says that the default username and password are admin admin, tried that didn't work. Tried admin and no pass, tried many combinations, none worked. I asked some other users and they said that the isp is blocking the users from logging in as admins, and blocking the reset button, and said that there's a hack where you do something like: cmd telnet "router ip" and do something like dumpcfg. Could you please give a better explanation on how to gain admin privileges on your own router if your isp is not letting you do so by default?

• Font name used in files shared between OSX and Windows

  - by Paul

  Our designer uses OSX, and creates InDesign or AI files. They are then passed to us for changes. When we open the files on Windows, we are told that fonts are missing. In this example, the Futura font is being used. The Windows machine has Futura installed, from BitStream. The nane of the font is "Futura Std", whereas on OSX, it is simply Futura. So InDesign chooses a random font to substitute Futura with on Windows, it does not choose Futura Std. Now we can use the Find Font feature, and change all the instances of "Futura" to "Futura Std", but if we pass the file back to the designer, they have to then do the reverse. What is the right way for managing this?

• Benchmark an SSD

  - by Taylor Huston

  What is the best way to test/benchmark an SSD to make sure it's doing it's job. I invested in an SSD, have my OS on it, want to make sure I am getting my money's worth. I have heard some people making claims along the lines of: "I've had my SSD for X months and my read/write speeds have dropped Y%'. What is the best way to test for things like that (and what are good numbers to look for)? For reference I have a Samsung 830 128gb.

  - by user2789433

  This question already has an answer here: How does IPv4 Subnetting Work? 5 answers If you click on this link WHO IS query You will see the results from a who is query for a random IP address. On the line "inetnum": "122.4.0.0/14", What does it mean for the prefix to be 14? I am using this as a reference Subnet Mask Cheatsheet While resolving it, I get a very wide range which is something like 122.7.0.0-122.4.0.0 I am not able to understand how the IP range is calculate from the subnet mask and I am only able to find calculators online and not a method to solve it.

• Conditionally format row based on cell value in Excel 2011 Mac

  - by kojiro

  I'm using Excel Mac 2011. I have read some of the other answers, but this question is different because I want to apply conditional formatting to an entire row when its cell in column B contains the value 'Y'. Simple conditional formatting just formats that one cell. Whenever the field at column B for any given row contains the value 'Y', I'd like to format that row. Using Mac Excel's so-called "classic" conditional formatting, I have this: I would really like to apply that to every row, but it just paints the entire sheet red (because $B$3 contains "Y"). I can't seem to figure out how to get the reference to whatever is in field B for this row in the rule.

• Launchd execute command when folder contents modified or changed.

  - by ThomasReggi

  For the past two days i've been trying to get a launchd plist to execute a script "program" when the contents of a folder on my desktop contents have modified or changed. I've gone through tons of configuration settings and have tried the Users/me/Desktop/folderinquestion and Users/me/Desktop/folderinquestion (with and without trailing slash). The script executes only when something is added or removed but it doesn't recognize when files are updated and subdirectories. launchd is really my last hope to getting this to working i've already exausted folder actions, and bash scripts, uninstallable linux methods etc. I have used Lingon to create my plists and have followed this youtube tutorial. Any help would be greatly appreciated. This is what I have right now, and like I said does not work when folder is modified or changed IDEA: Thinking about creating two separate plists that reference each other one plist can watch a folder for additions and subtractions and when one occurs it can create another plist that watches every file in the folder, this could also be recursive and count in for subdirectories.

• Outlook 2007 VBA/Macro

  - by user27538

  Hi, I am a very basic user new to macros and vba. My problem is that I recive online orders to which i need to click an auto generated unique order hyperlink to confirm receipt of the order within a specified time period. This is a mundane task having to be on 'standby' and was wondering if there was a way to have this link automatically clicked when the email arrives. Just to reiterate the link has a unique reference and is different on each email. Please bare in mind that I am a very basic user and would probably require step by step instructions. Many thanks in advance

• Automatically insert cell references from one sheet into other in Calc

  - by user123456

  I have spreadsheets in OpenOffice.org Calc that consist of the first sheet and an arbitrary number of additional sheets, each collecting data for a specific month. The Month sheets have an identical structure. The first sheet is supposed to provide an overview to the most important numbers in the month sheets. Whenever I add a Month sheet, I want it to appear automatically in the Overview sheet with the structure given below. So, for each Month sheet, copy or reference some of the cells into the Overview sheet: {Referenced Sheet Name} | Fixed Header1 | Fixed Header2 | Fixed Header3 Fixed Label 1 | {CellRef 1} | {CellRef 2} | {CellRef 3} Fixed Label 2 | {CellRef 4} | {CellRef 5} | {CellRef 6} I know how do to this for just one sheet by hand, but I have no clue how to make Calc do this automatically for me. Is it possible at all? Any help appreciated.

• Enable fastcgi on SSL Virtualhost

  - by ggstevens

  Debian 7.5 My VirtualHost for port 80 works fine with the ifmodule for fastcgi. However, it does not work with the VirtualHost for port 443.

• Dual-boot two instances of the same copy of Vista using same serial number

  - by fred.bear

  I have a single Vista OEM registration number which has been registered to the current hardware (single partition only), and I want to use it for two instances of dual-booted Vista... Because both Vistas will be running on the same hardware, (and obviously only one at any one time), will they both be recognized as genuine to Windows Update etc... ie will they both pass the Windows Genuine Advantage requirements? .. The only difference between the hardware involved will be the partition. Also, are there any special issues with dual (tripple?) booting two instances of Vista and also one Ubuntu OS?

• IIS7 folder permissions

  - by Eanna

  I build a basic WCF service that I now want to host in IIS7 under Windows Server 2008 R2. I added the service as an application under the default web site but whenever i try to run the application I get the following error: HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Config Error - Cannot read configuration file due to insufficient permissions The only way I can get this service working is if i choose to "connect as" the server Administrator when adding the service. the "application user (pass-through authentication)" option does not seem to work. Could anyone help me out, I've just started using IIS7 and have no idea what to do... Thanks

• WOL not working

  - by Maciej Swic

  I have a Marvell Yukon integrated NIC and i have installed the WOL package on my freeBSD-based NAS. I'm trying to wake my PC using the command "wol M:A:C:A:D:D:R".

• 2 HP Procurve 4000M switches and Comcast SMC Gateway

  - by Cole Tierney

  We've got 2 HP Procurve 4000M switches joined by a trunk. Switch 1 is connected to a Cisco 2600 router which is connected to a T1. Internet traffic for hosts on switch 2 must pass through the trunk to switch 1. We're now switching to Comcast who's given us 4 port SMC router. I would like to connect each switch to the comcast router to reduce traffic on the trunk, but I don't want to create a loop. The switches support spanning tree protocol, but I don't know how this would work with the comcast router. Would a triangle network like this work? Thanks for any tips.

• Ngnix as reverse proxy for Apache name-based vhosts

  - by Ben Carleton

  I am running several websites on Apache currently utilizing name-based vhosts. All of the sites are on the same server. I would like to add Ngnix on a new server to sit in front of Apache as a caching reverse proxy. What is the best way to handle the multiple name-based vhosts? Should I simply have Nginx handle the names and run each Apache vhost on a separate port? Or is there a way to just have Nginx pass the hostname to Apache and have apache take care of the domain names?

• IIS reveals internal IP address in content-location field

  - by saille

  Referring: http://support.microsoft.com/kb/q218180/, there is a known issue in IIS4/5/6 whereby it will reveal the internal IP of a web server in the content-location field of the HTTP header. We have IIS 6. I have tried the fix suggested, but it has not worked. The website is configured to send all requests to ASP.NET, and I am wondering if this is why the fix, which addresses IIS configuration, has not worked for us. If this is the case, how would we fix this in ASP.NET? We need to fix this issue in order to pass a security audit.

• Rewrite URL before passing to proxy Lighttpd

  - by futureelite7

  Hi, I'm trying to setup a reverse proxy in lighttpd, such that all requests (and only those requests) under /mobile/video is redirected to the / directory of a secondary web server. This is pretty easy in apache, but I can't for the life of me figure out how to do so in lighttpd. $HTTP["url"] =~ "^/wsmobile/video/" { url.rewrite-once = ( ".*" => "/test/" ) proxy.server = ( "" => ( ( "host" => "210.200.144.26", "port" => 9091 ) ) ) } I've tried using the http["url"] directive, but lighttpd simply ignore those requests and continue to pass the full url to the secondary server, which of course chokes and throws 404s. However, if I do a global rewrite then everything gets forwarded to the secondary server, which is also not what I want. How do I go about this task?

• Winxp system context menus blank after last security update

  - by Peter Rowell

  Because of a CERT advisory of several out-of-band security updates released by MS I did a Critical Updates pass on my WinXP Pro SP3 machine. I now have the situation where it seems that all of my WinXP-generated menus come up with all items black. If I wave the cursor over the menu, the items will update as they become active (go blue) and then update correctly (to black-text-on-white-background) as they go non-active. Separators (which never get a hover event) stay black. App-level context menus seem to work fine (Firefox, OpenOffice, etc.) with the exception of Windows Explorer and Internet Explorer, which both exhibit this behavior on both their context menus and on their menu bar drop down menus. I'm assuming that's true because they are all using the same library code. Thoughts? Fixes? Help!

• How to use auto-discovery with iDRAC Enterprise?

  - by jwiz

  All I want to do is: have "auto discovery" enabled on my iDRAC enterprise at the factory rack the server, cable iDRAC to dhcp-enabled management network have the iDRAC DHCP, find the "Provisioning Server", and get updated with login credentials (for us to use with racadm, idrac webui, etc.) I don't need to do any configuring of the system, install OS, or anything else. I just want idrac to dhcp out of the box, and end up with an account that can be used to login. All the docs I can find on Dell's site refer to a "Provisioning Server", but I honestly can't tell if they have some reference product, or if they only have software that "integrates" with other vendor's existing management systems. I'd be happy to set up whatever is needed, I just can't find something that explicitly describes the process (only references to the fact that it is supported).

• Best way to find the computer a user last logged on from?

  - by Garrett

  I am hoping that somewhere in Active Directory the "last logged on from [computer]" is written/stored, or there is a log I can parse out? The purpose of wanting to know the last PC logged on from is for offering remote support over the network - our users move around pretty infrequently, but I'd like to know that whatever I'm consulting was updating that morning (when they logged in, presumably) at minimum. I'm also considering login scripts that write the user and computer names to a known location I can reference, but some of our users don't like to logout for 15 days at a time. If there is an elegant solution that uses login scripts, definitely mention it - but if it happens to work for merely unlocking the station, that would be even better!
