• Packaging python software with custom dependencies

  - by viraptor

  Hi, I'm looking for a good way to package a Python application that is going to be deployed on a Debian server. The application itself depends on some modules which are not included in base Debian repository, although they might be in the future. This creates some problems... I depend on some patches to those modules. If the original module gets installed one day, the application will break. However if I install everything I need in a virtualenv just for that application, I lose the ability to upgrade Python itself (in case of security updates). The third option would be to rename my fork of the upstream module and just treat it as a completely separate one. But that would mean changing the code (not much work, but it wouldn't be that clean / universal anymore). Are there any other options that I missed? Are there any pros / cons I didn't see in the solutions above?

• Reliability of S.M.A.R.T.?

  - by Mark

  I've been using ActiveSmart to monitor my hard-drives health for a few weeks now, and its telling me my brand new 1.5 TB hard-drive is half-dead already. About on-par with one of my hard-drives which I know is at least half dead because I've been having some read errors and heard ticking noises. Now I haven't actually noticed any problems with my 1.5 TB drive; should I be concerned that it's going to crap out on me too? Or could ActiveSmart be giving a mis-diagnosis because I use it a lot or something (I've used up 795 GB in the 2 and a half weeks I've had it). The events that ActiveSmart has been catching is "Hardware ECC recovered". Maybe these new fangled super big hard-drives somehow rely on ECCs to squeeze out the extra space, but this isn't actually a cause for concern?

• Segmentation Fault with mod_include

  - by Benedikt Eger

  Hi, I'm using a rather complex structure with multiple ssi-includes, set- and echo-commands. The first document writes a lot of set-commands, includes another document which then again includes a third document. On the last included document the variable values are printed using the echo-command. I noticed that with an increasing number of variables the probability for a segmentation fault to happen rises. Did anyone experience something similar? How do I go about debugging such a problem? I'm using IBM_HTTP_Server/2.0.47.1-PK65782 Apache/2.0.47

• pfsense CARP - wan failure on firewall

  - by eldblz

  I have recently configured 2 firewall (on 2 DELL PowerEdge R210II with ESXI 5.1) with pfsense. We have several LANs and 2 WANs. Everything is running fine but i have a strange behavior: i can access internet from alla LANs but not from the firewall (itself). For example the firewall cannot retrive package information or if i setup a gatway monitor ip (like google 8.8.8.8 ) this fails. These are the screenshots of firewall configuration: http://imgur.com/a/LNuMz#0 ATM i kept firewall rules to minimum to avoid problem or conflicts. Any ideas how to solve the problem? Thank you in advance.

• OS X Address Not Available - How do I open this port?

  - by GeoffreyF67

  I am trying to get xdebug working on my snow leopard box. It uses port 9000. When I ask slickedit to monitor this port is gives an error that the address is not available. I've gone to canyouseeme.org to see if the port is open. It says the port is NOT open. I've verified that I have that port forwarding to my box from the router and i do NOT have the mac firewall running. I'm stumped. Any ideas?

• Unable to connect to another computer from the Task Scheduler on Windows 7

  - by Clem

  I am getting the following error when trying to connect to another computer from the Task Scheduler on Windows 7: "The remote computer was not found." The computer that I am trying to connect to is definitely on the network as I can ping it and browse its shared folders in Windows Explorer. Note that I get the same error message when trying to perform the same operation from Performance Monitor. This suggests that I need to something to enable remote connection to the Task Scheduler. I am not very experienced with Windows administration and I am not sure where to look. To give a bit more context, I want to use the Task Scheduler to automatically start Perf Mon on a few machines at my company. I'd like to setup the Task Scheduler remotely. Does anyone know what I need to do?

  - by adnan kamili

• How to close the logon process named NtLmSsp ?

  - by Aristos

  I have a windows 2003 server and time to time I am getting many login failures like this one. Logon Failure: Reason: Unknown user name or bad password User Name: administrator Domain: xx.xx.xx.xx Logon Type: 3 Logon Process: NtLmSsp Authentication Package: NTLM Workstation Name: XLHOST Caller User Name: - Caller Domain: - Caller Logon ID: - Caller Process ID: - Transited Services: - Source Network Address: 173.45.70.100 <- hacker Source Port: 4722 AND Logon attempt by: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0 Logon account: user Source Workstation: XLHOST Error Code: 0xC0000064 The question is, how can I close this process of login ?, what I have left open and some one can try to login ? Some notes: I login to the server using tunneling, nothing is open except dns, email, and web ports, not even ftp, and all default ports are change and hidden. I also monitor port scan and capture any one that try to find the hidden ports. Probably it is something open... Thank you in advanced.

• Ubuntu displaying GDM but no login

  - by Shawn

  Ubuntu (Wubi, Lucid Lynx) boots and shows the login screen itself with the background and plays the boot sound but a list of users is never displayed. A mouse is on screen and I can move it but, alas, it does nothing. Dropping to a virtual term with CTRL+Alt+F# drops me to a cursor but I can't actually input anything. I can't boot into single-user with GRUB since it's Wubi and it never specifies a boot kernel directly in GRUB's initial menu.lst (only in files that it then reads from). Other details that may be helpful: Single monitor Same video card that's been working for months No new hardware Edit: I ssh'd in since it evidently booted up the sshd which is handy. dpkg-reconfigure gdm didn't do anything helpful. I do, however, get a "no seat-id found" when manually running it.

• Use router as external high powered Wi-Fi adapter

  - by skywinder

  I need a powerful external Wi-Fi adapter for a couple of days. I heard that some types of router support this mode, allowing me to connect the router to my notebook and just use it as an external Wi-Fi interface. Is it possible to connect a router as an external Wi-Fi adapter? How can I determine it? Updated: My purpose is to set the router to monitor mode and check networks around through my notebook to provide better configuration for my network (power, channels, etc). My internal notebook Wi-Fi adapter is too weak for this purpose. Should I use special drivers for that? If yes, can someone describe, step-by-step, how to do it? p.s. I want to use ASUS RT-N56U as an external Wi-Fi adapter on OS X or Ubuntu.

• Why does ganglia think my host is down?

  - by NZKoz

  I have ganglia set up to monitor our staging server, it's working great but I'm confused by the definition of 'down' to ganglia. There's a single node, running gmetad, gmond and the web frontend, but some small percentage of the time the web frontend shows some confusing output. Despite the fact that it's a single server in the cluster, and that server is the one serving the web interface, the dashboard output insists that the host is down. Then below that it has a graph which shows 50% down, 50% up. You can see an example of this here: http://i.imgur.com/MCWaS.jpg There's obviously something confusing ganglia somewhere, but I'm not sure where to start looking. Unfortunately googling for any combination of 'ganglia' 'down' 'metric name' seems return nothing but other people's ganglia installations displaying the same nonsense. Any tips on where to start looking would be greatly appreciated

• Automatic Excel Script

  - by Thomas

  I am a 6th year medical student and I'm working on my thesis. I have no experience with programming whatsoever, a friend recommended me to post my question here. I am strugling with the following problem: I have data of 400 patients, stored in 400 different excel files. Each file contains 34 columns in a specific order, let's say A to Z. The order is the same in each of these 400 files. Now I need to a make a new excel document that contains the first column of each patient. So I need all the first columns of my 400 different excel files, lined up next to each other in a new document. Preferebally in the form of a automatic script. After that I want to do the exact same thing but for the second column, then the third and so on. This is probably a problem that has already been solved. Otherwise could someone help me out? You have my thanks!

• Monitoring ASA packet loss via SNMP

  - by dunxd

  I want to monitor packet loss on my ASA 5505 VPN endpoints using SNMP. This is so I can graph the rates in Cacti and/or get alerts in Nagios. However, I am not sure what SNMP values I should use to measure packet loss. In the ASA I can run sh interface Internet stats to show traffic statistics for the interface connected to the Internet. This shows 1 minute and 5 minute drop rates. Are these measures an indicator of packet loss? Are there SNMP values I can access that correspond to those values? Should I be looking at different values? Is the ASA even able to measure packet loss?

• Displaying Nagios on a 52" 1080p screen

  - by gdm

  I'm using a 52" 1080p LCD screen to monitor Nagios, positioned where most of the users can see it. Using the default Nagios web view sort of sucks, since you need to increase the text size a decent amount so it's legible from a distance, and then the "Current Network Status", "Host Status Totals", and other boxes along the top take up the majority of the screen realestate; you can't really see the list of host details. Is there a custom view for Nagios, or a plugin, or something available which is meant to display Nagios details on a large screen with large text?

• What cable to connect Inspiron 1720 to HDMI TV?

  - by Bernhard Hofmann

  Hi I'm a little confused to say the least when it comes to video formats and protocols. I'd like to view my laptop output on my HD TV. The TV has HDMI, S-Video, and RCA inputs. My laptop has a VGA female port on the side for driving a 2nd monitor, and an S-VHS output at the back. No, it has no DVI, which I've heard is a poor decision from DELL, and even poorer decision on my part to buy it. Can I get true HD output from this to my TV? What cable do I need, or would I need a converter? Any other suggestions are also welcome, such as how to get something close to HD on my TV. Thanks! Bernhard

• Spam just keeps on coming

  - by Campo

  I administer a Windows Server 2003 with Exchange 2003 as well as GFI installed. I am watching the GFI dashboard and every third email is spam. Not only that it goes to a non existent address then the [email protected] sends out an NDR to the sender. Should I be worried about this? I know it is directory harvesting but we have directory harvesting turned on in GFI and I do see it is working but obviously doesn't work for emails that don't exist. My issue is I would turn off NDR but then people who legitimately mistype and email address to our domain will never know their email did not get to the recipient. What do others do to combat spam? Is 3 times the amount of spam to ham normal? We filter out 90% of the spam but some does get into the users inbox. Thanks for the suggestions and advice!

• Accessing Windows 7 Printer from Ubuntu Linux via LPR/LPD or Samba

  - by nitbuntu

  Hi, I'm having difficulty printing from my Linux (Ubuntu 10.04) based PC to a printer connected to a Windows 7 machine. I was trying to connect using Samba (version 3.5.6) but this always brings up an authentication screen which never accepts any password I use. So I read somewhere that an alternative is to access the Windows printer via LPR/LPD. I added an LPR/LPD printer in Windows 7, but even within Windows 7, I am not able to print as the print que monitor shows as 'printer busy'. The printer in question is an Epson Stylus DX7400 and works fine when using the standard USB ports....but doesn't when I use with the LPR/LPD ports. I even opened up the TCP/IP port 515 in my McAfee firewall without any success. Any help with this would be highly appreciated. Additionally, does anyone have any idea how I can get Samba working for me?

• Is there a successor to NTFS?

  - by hak8or

  What I am asking is if there is any file system that is known to be a possible successor of NTFS? I am asking because I just bought a new external, and realized that the path to a file, including the file name itself, cannot add up to more than 255 characters. This is known as the "Long File Name" by microsoft. I am assuming this is due to the file system limitation, so I am searching for any possible alternatives. I have a windows 7 based machine, but I am under the assumption that there would be third party software that would work with windows to make the new file system accessible by windows explorer.

• How to cache streaming video and silverlight with squid windows reverse proxy

  - by V. Romanov

  We have an intranet web server running a silverlight application (ACTUS media monitor if anyone cares to know). The server is used to record video and stream it to clients through a CDN solution. We want to put a reverse proxy in between the server and CDN provider in order to remove the office network bottleneck that's currently strangling us. I've set up SQUID for windows on a separate machine outside the network using squid BasicAccelerator configuration setting. It seems to work as far as the reverse proxy is concerned, requests are forwarded and the application is working but it doesn't seem to cache anything (no space is used on the drive where squid is installed). I found to explicit setting to turn caching on in squid, so i assume it's on by default. Perhaps I need some other trick to make the video and/or silverlight cacheable? Any help will be appreciated. Any info you need to help me will be provided at once. Thanks in advance!

• Lenovo G530 laptop screen flicker

  - by Kevin

  I have a Lenovo G530 laptop that has an issue with screen flicker that is getting worse. The computer screen will start going thru a crazy screen flicker then will stop and start again. I have already checked cable connection to lcd on motherboard and reseated connection as someone suggested in another posting I found online that resolved issue. I am starting to think it might be a bad inverter or screen because I have hooked up laptop to external monitor and it is running fine with no flickering happening when the flickering is occurring on laptop. I am attaching a link to a small video I shot of the issue as it is occurring on laptop screen. Does anyone have any further suggestions? Bad inverter or screen? Screen flicker vid

• I want to play one podcast only on iTouch, but they play in series one after the other.

  - by Eddy

  I download multiple podcasts from one source, eg, five episodes of Naked Scientists. I want to listen to one only, but when the first finishes it automatically goes to the second, and third etc. I want to listen to just one episode at a time and have the iTouch turn off when it is finished (this is a sleep-aid for my insomnia...I don't want it playing all night !) A "Genius" suggested making playlists, but although you can make a podcast playlist, it does NOT sync. Please help. thanks, Ed3339

• How to get pen input to draw?

  - by Cameron J

  I just got a crappy little Hyundai pen input module To use on a normal Windows 7 HP laptop, it works quite well with the Hyundai software, but that's in Chinese, and the input only stays on the screen for a second. When I try to use it in Paint, it just draws a dot, and switches back to an unclicked state, similarly, it's impossible to move a window. Is there ant way I can keep the click held down when the pen is touching the pad in order to draw, or is there any third party software anyone knows of that can do this?
