• How powerful of a PC do you need to edit HD videos?

  - by Xeoncross

  I have a Core2Quad Q8200 (2.3GHz) with 4GB of RAM, a 512MB PCIe video card, and a SATA-2 HD. Yet it still isn't fast enough to edit 720i/p video in Sony Vegas or Adobe Premiere/Aftereffects. My RAM usage never peaks over 1.6GB, but my CPU cores make it to 95% quick! Right now the preview panes in all these programs lag to bad to actually work on the videos. I get to see 1-3 frames every second or two! So how fast do I have to go? At what point will my CPU be fast enough to actually edit these videos? I have to assume that regular people and their regular sub $2k computers can actually work with this footage. Another way to answer this is, how fast is the PC you used to edit videos? Update: I'ts worth noting that now that I have Adobe Pre/AF CS4 I am more interested in getting that working than my older Vegas 6. If you didn't have to re-run RAM preview every, single, time you made one change it would be my answer. But since I like to test many filters and effects before choosing one - I have to re-render a 1-sec section of footage over-and-over and it drives me nuts waiting. Perhaps a motherboard with Dual Xeon chips or something would be able to handle this. It would probably be as much as a dual-crossfire setup and would also speed up other applications.

• What is the advantage of not running as root? [closed]

  - by Shmuel Brill

  Possible Duplicate: What's wrong with always being root? All modern brands of Linux highly discourage (or disable) one from running as root instead of a normal user. I do not understand why. As a "normal" user, one could Download a rouge program from the internet. Run it (After all, one isn't root, what can it do). It installs itself in .bashrc or .xinitrc It writes a rouge "sudo" and "su" and adds . to the path Not noticing that . is in path, one runs sudo. The rouge program now has root password and can do anything it wants in the system. Even if 3-6 doesn't happen, the program could still Be part of a botnet. Read all files in the home directory and send them back (mine for SS#, Credit Card numbers, bank account numbers, etc). Send spam. Run a backdoor server to allow an attacker a chance to connect to the machine to determine vulnerabilities. It seems that the whole "permissions" thing (root/non-root) is just to prevent amateur crackers from getting into the system, so the question is: Is there a point in avoiding running as root, and is there a way to protect oneself if one wants to run unsafe code?

• Localhost problems on Mac OS X 10.7

  - by Maya

  Sorry for the duplicate post ( http://stackoverflow.com/questions/9720871/localhost-problems-on-mac-os-x-10-7 ), but I got the advice that this is a better place to ask my question: I want to access a mysql server remotely over ssh. So I used port forwarding to access the remote 3306 port on my localhost as 8383. The ssh connection can established successfully. But when I want to telnet onto port 8383 on localhost I get the following error: ~: telnet 127.0.0.1 8383 Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused telnet: Unable to connect to remote host I tried the same on a friends Laptop (also Mac OS X 10.7) and it worked fine, so it is very unlikely that the ssh connection is the problem. I assume it has something to do with my local network configuration. I turned off IPv6, just in case. My /etc/hosts looks like this: 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost I would greatly appreciate any help. Please point me in the right direction if this is not the right place to ask this question.

• switchless Infiniband between two servers on RHEL 6.3

  - by exfizik

  I have 2 servers running RHEL 6.3 which have 2 port Infiniband cards >lspci | grep -i infini 07:00.0 InfiniBand: QLogic Corp. IBA7322 QDR InfiniBand HCA (rev 02) I'm interested in connecting them directly to each other bypassing an Infiniband switch (which I don't have). Quick googling showed that at least in some configurations it's possible. I installed all RedHat Infiniband packages with yum groupinstall "Infiniband Support". However, ibv_devinfo shows that both ports in each card are down, which indicates that cables are not connected. But the cable is connected, although the LEDs are off on the cards (not a good sign). Another source of confusion for me is that according to this, RedHat doesn't come with OFED packages and I'm slightly hesitant to install them from source due to the lack of RedHat support for them... So where am I going with this? The questions I have are: is it possible to have a switchless/direct Infiniband connection between two servers the way I described above? If it's possible, do I have to use the OFED packages or can I configure everything with just the packages coming with RHEL. Why are the LEDs off on my servers even though the cable is connected? Any additional input/advice/pointers would be appreciated. P.S. I followed this guide for installation instructions. The Infiniband cards are clearly recognized by my OS and the rdma service is running. Update: I have opensm installed. When I run it it says: OpenSM 3.3.13 Command Line Arguments: Log File: /var/log/opensm.log ------------------------------------------------- OpenSM 3.3.13 Entering DISCOVERING state Using default GUID 0x1175000076e4c8 SM port is down and stays at that point.

• SSH public key authentication -- always require users to generate their own keypair?

  - by schinazi

  I was working with a partner today that I needed to upload files to my server using scp. I have passwords turned off in the server's SSH configuration, so I wanted them to use public key authentication. I generated the keypair for them on the server and gave them the private key and put the public key in the appropriate authorized_keys file. After a bunch of problems with them setting up their job, they finally got a more experienced sysadmin involved on their end, and he scolded me for handling the key generation this way. He said that by giving them a private key generated on my system, I had enabled them to do a brute-force attack against other keys generated on the same server. I even asked him "so if I have an account on a server, and I can log in with a password but I want to automate something and I generate a keypair on that system, does that then give me an attack vector for brute forcing other users' keys?" and he said yes. I've never heard of this, is it true? Can anyone point me to a discussion of this attack? Thanks in advance.

• Time drift in Cloud Server - need to mainpulate GRUB config

  - by Aditya Advani

  We are hosting a VPS on a popular host and are experiencing a regular time drift of several minutes a day forward (approx 7). Linux Kernel: 2.6.18-164.11.1.el5 GNU/Linux Distro: CentOS release 5.4 (Final) We reached out to our hosting provider and their support advised us " This is a known issue with Cloud Servers. To fix this you will need to add one line to your grub config located at: /boot/grub/menu.lst The line you need to add is: noapic nolapic divider=10 nolapic_timer This should correct this issue. You will need to restart after this is added in. " Because I am wary of manipulating grub, mostly I'm terrified that our server may fail to restart - I ask you guys, the pro *nix admins - where exactly in this file does the recommended insertion below: # line from 1&1 for time syncing issue (Case 5163) noapic nolapic divider=10 nolapic_timer go? Please specify where exactly, and whether the order of commands is or is not important. Why is the block below "title CentOS ..." indented? If someone could give me an overview of how this works or point me to a resource that's easy to follow, that's what I'm looking for immediately, a light overview or basic understanding of what I;m doing. If GRUB and bootloaders are a deep dark treasure trove of kernel hacking or something, that's great well-recommended in-depth resources are also very welcome. This is my current /boot/grub/menu.lst # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file #boot=/dev/sda # serial --unit=0 --speed=57600 terminal --timeout=5 serial console timeout=5 title CentOS (2.6.18-164.11.1.el5) root (hd0,0) kernel /boot/vmlinuz-2.6.18-164.11.1.el5 ro root=/dev/hda1 console=tty0 console=tty initrd /boot/initrd-2.6.18-164.11.1.el5.img MOST IMPORTANT: I need to know where in the file above it is appropriate to paste the suggested line so I can confidently restart my VPS after manipulating GRUB config

• How to update the hard disk device drivers for a ghosted hard drive image so it can run on different hardware: Ultra ATA > SATA

  - by rism

  I've ghosted a Winxp machine from one laptop with Ultra ATA drive, and would like to set it up on another laptop as a multiboot option on another hard driver with a SATA drive. I can install the partition fine but if i make it active and try to boot it it blue screens. The blue screen is so fast i cant even read it, other than to make out it's saying "something", im picking probably hard drive as it goes through POST fine. So basically i would like to boot into my Win7 OS, and then somehow manipulate the XP partition to use updated drivers for the new hard drive/laptop so that i can then at least boot into the XP OS on the new machine and update all the other drivers in safe mode or whatever to get it to run. I assume someone is going to tell me to just do a fresh install, but that kinda defeats the purpose of ghosting at this point. There is a significant amount of personalisation, development setup on the XP machine that i would like to just transfer as is. As it stands ive invested minmal time in getting it to run, just a ghost and recovery and then a blue screen boot or two, so its still well worth it to me, time wise to try this way. Thanks.

• Windows Vista will not boot; the file header checksum does not match the computed checksum

  - by Magnus

  Right out of the blue, my wife's Sony Vaio stopped booting. This, not so fun, error message displays immediately after POST: The system cannot boot. The file is possibly corrupt. The file header checksum does not match the computed checksum The repair option on the Vista DVD says everything is fine and dandy, it couldn't be more happier or more clueless... Any ideas? Update: CHKDSK reports no issues. CHKDSK /r reports no issues. (Heck, both Windows Repair and CHKDSK could just as well tell me that I have won on lottery or that the earth is flat... ) Some have reported that a mem diagnostic could help, but for me the mem diag has just ran through 5 passes. It doesn't seem to help. According to Sony, pressing F10 should bring up the restore menu, but it doesn't, the error pops up straight after Bios POST. It seems that this error is first in line of all options at this point, and is doesn't put a smile on my face. I have attached an external USB drive and copied all user data/documents to it. I feel an OS re-install is around the corner.

• PHP 5.3 on IIS gives 404 error in CGI mode

  - by reinier

  Slowly losing my mind here. I had PHP 5.2 working fine (ISAPI) under IIS, but for some extension I needed 5.3. So no worries, I installed this but it turns out ISAPI is not supplied anymore. I followed the install tutorials for fastcgi and ended up with a 500 internal server error for every PHP page served. So my current situation is: I have fastcgi removed. In my websites I have added PHP (head, get, post) and routed them to c:\php\php-cgi.exe. Result: every PHP page I try (even the ones with just text) gives 404 not found error. Any HTML file I put in the same folder, serves without a hitch. Who can help me please... How hard can something like this be right? For me apparently very hard. Extra information: ran the installer as suggested below. Set it to use fastcgi. my fcgiext.ini file looks like this now: [types] php=c:\php\php-cgi.exe [c:\php\php-cgi.exe] exepath=c:\php\php-cgi.exe from the command-line a 3 line PHP file with just phpinfo(); works fine from the server the same PHP file with just phpinfo(); results in the internal server 500 error. from the server a PHP file with just text works fine when changing the document types in IIS management console and point the PHP extension directly to c:\php\php-cgi.exe results in 404 for every PHP file the php.ini is the php.ini.production file which came in the distribution. No edits were made. Setting the IIS PHP handler directly to PHP (not via fastcgi) c:\php\php-cgi.exe results in the following: display a PHP page with only text....works fine display a page with only phpinfo(); results in 404 not found

• "A disk read error occurred" when booting XP disk image in VirtualBox

  - by intuited

  I'm trying to boot an XP installation cloned into VirtualBox from a real drive. I'm getting the message A disk read error occurred Press Ctrl+Alt+Del to restart whenever* I try to boot the machine. * This is not strictly true: with AMD-V enabled, the boot process appears to not make it this far and instead hangs at a black screen with cursor. I created the VirtualBox image from the original drive using the following method: $ sudo ddrescue -n /dev/sdd sdd.img logfile # completed without errors $ VBoxManage convertfromraw sdd.img disk.vdi The original disk (and the image) contain a single NTFS partition with XP installed on it. The owner of the drive indicates that it did boot okay the last time the system made it that far. The (Pentium 4) system has a broken (enormous) heat sink, so at some point it failed to boot because it would quickly overheat and shut down. If I boot the VM from a live cd, I am able to mount its /dev/sda1 without any problems. I ran ntfsfix and didn't have any luck. I've read through the instructions on doing this. I didn't really follow them. For example, I didn't run MergeIDE before imaging because the machine was not bootable. However, the symptom of that problem seems to be quite different. The emitted message is contained in the volume boot record of the XP partition, which leads me to suspect that this is a problem with the core operating system bootstrap procedure, and not related to anything in the registry. I don't have an XP boot CD.

• NRPE unable to read output, but why?

  - by ticktockhouse

  I have this problem with NRPE, all the stuff I've found so far on the net seems to point me at things I've already tried. # /usr/local/nagios/plugins/check_nrpe -H nrpeclient gives NRPE v2.12 as expected. Running the command by hand (as defined in nrpe.cfg on "nrpeclient", gives the expected response nrpe.cfg: command[check_openmanage]=/usr/lib/nagios/plugins/additional/check_openmanage -s -e -b ctrl_driver=0 bat_charge "Expected response" But if I try to run the command from the Nagios server I get the following: # /usr/local/nagios/plugins/check_nrpe -H comxps -c check_openmanage NRPE: Unable to read output Can anyone think of anywhere else I might have made a mistake with this? I've done the same thing on multiple other servers with no problem. The only difference I can think of with this is that this box is RHEL 5 based, whereas the others are RHEL 4 based. Those two bits above that I've tested are the what most people seem to suggest when people have had this problem. I should mention that I get a weird error in the logs when I restart nrpe: nrpe[14534]: Unable to open config file '/usr/local/nagios/etc/nrpe.cfg' for reading nrpe[14534]: Continuing with errors... nrpe[14535]: Starting up daemon nrpe[14535]: Warning: Daemon is configured to accept command arguments from clients! nrpe[14535]: Listening for connections on port 5666 nrpe[14535]: Allowing connections from: bodbck,combck,nam-bck Even though, it's plainly reading that /usr/local/nagios/etc/nrpe.cfg file to get the stuff it's talking about further down..

• Error with Apache, Nagios and Snorby integration

  - by user1428366

  I'm trying to use apache to serve two different websites (Nagios and Snorby). The problem is that when I try to see the "/snorby" website, apache sends me the "It works" page. If I try to access to "/nagios" it works perfectly. Snorby is running under ruby passenger .This are the config files. <VirtualHost *:80> ScriptAlias /nagios/cgi-bin "/srv/nagios/sbin" <Directory "/srv/nagios/sbin"> # SSLRequireSSL Options ExecCGI AllowOverride None Order allow,deny Allow from all # Order deny,allow # Deny from all # Allow from 127.0.0.1 AuthName "Nagios Access" AuthType Basic AuthUserFile /srv/nagios/etc/htpasswd.users Require valid-user </Directory> Alias /nagios "/srv/nagios/share" <Directory "/srv/nagios/share"> # SSLRequireSSL Options None AllowOverride None Order allow,deny Allow from all # Order deny,allow # Deny from all # Allow from 127.0.0.1 AuthName "Nagios Access" AuthType Basic AuthUserFile /srv/nagios/etc/htpasswd.users Require valid-user </Directory> </VirtualHost> And the other one is this: <VirtualHost *:80> #Alias /snorby "/var/www/snorby-2.6.0/public" # !!! Be sure to point DocumentRoot to 'public'! DocumentRoot /var/www/snorby-2.6.0/public <Directory /var/www/snorby-2.6.0/public> # This relaxes Apache security settings. AllowOverride all # MultiViews must be turned off. Options -MultiViews </Directory> </VirtualHost> If I disable the Nagios webpage, the Snorby webpage works. I think the problem is Snorby because when I try to access to the Ip address with Nagios page disable, the webapplication redirects me to http:// myserverip/dashboard. Can anyone help me please?

• Backup server (OSX) like time machine to backup remote ubuntu 12.04 server [on hold]

  - by Mad

  I've searched my ass of for an good solution to backup my ubuntu server thats in a datacenter. Local we have an osx server with some external drives attached to it. This is for the local working stations that handle timemachine. What i like to do is fetch the files (or mount the root of my ubuntu server) and make an time machine backup from it. I just have one problem that if my osx server crashes i can't put back the system because it contains not only the osx server but also the ubuntu server from the data center. I've used Back in time on ubuntu to do the exact same thing but this was to Ubuntu (local) from Ubuntu (datacenter). So does anybody has an solution? Here are my requirements: Set time intervals for backups; need to be backed up nightly. Set time intervals for keeping backups; hourly, weekly, monthy etc Able to back up all computers and servers from an offsite location the local osx server (10.9). Manageable from that one location to login with ssh to do rsync or rsnapshot Has a GUI (osx) Act like time machine, backup only the files that has been changed. Restore to a point back in time.

• Upgrading Visio 2000 to Visio 2007

  - by dirtside

  I have Microsoft Visio 2000 SR 1, and recently purchased Microsoft Office Visio Standard 2007 with the understanding (supported by the product info and some other research) that I'd be able to upgrade. However, when I install 2007, it tells me it can't find a previous install of Visio, but... it's right there! Here's the exact message: "Setup can't find a version of Microsoft Office on your computer. If Office is installed on a disk or network share, click the browse button to select the appropriate disk or share... (etc.)" No matter which directory or drive I pick (various Office installs, the old Visio install, various subdirectories) it gives the following message: "The path you have chosen does not point at a qualifying upgradeable product. Click 'Retry' to try again or 'Cancel' to quit setup." Any ideas? This is a legit copy of Visio 2007 (purchased from Amazon) and the copy of Visio 2000 is legit as well. I'm not sure what exactly the installer is looking for that it would consider a "qualifying upgradeable product". A specific file?

• Broken Creative DTT3500 Digital

  - by djechelon

  Hello, many years ago I bought a Creative DTT3500 Digital surround speakers system. It's been a while since my home theatre started behaving strange. During the past 6 months, I have noticed that the amplifier needed some time before correctly playing digital audio. Until a couple of weeks ago, it needed up to 5 minutes of very noisy "warm up" before playing an "almost" clear audio. Today, I found that even using the analog input (completely disabling digital inputs) the noise persists. Powering off and on the speakers doesn't work. Now, it's reasonable that after almost 10 years, the amplifier got broken. My problem is that I can't simply replace the speakers with another kit from another brand, since 2 speakers in my room are placed in the back wall, with coaxial cables going under the floor but not completely inside a single tube. I mean, I have coaxial extension cables starting from the DTT3500 amplifier, going into the wall, then under the floor in a plastic cable tube, then exiting the tube (still under the floor), connecting to the male coaxial connector of the original cable supplied by Creative, and continuing up to the point close to my bed where the speakers are. I could replace the speakers **only as soon as the new speakers have the same coaxial to bi-polar cables that Creative ships with DTT3500 Another option might be "repairing the amplifier", but I don't know if it's feasible, what should I or a technician look for in the amplifier, and how much would it cost (is it worth to repair or buy a new kit considering the problem above? What do you suggest me to do, basing on the above observation? Thank you.

• atl90.dll version 9.0.30729.4148 is missing in WinSxS folder

  - by mkva

  Hi I have the following problem: when starting Visual Studio 2008, it says "Cannot find one or more components. Please reinstall the application." and stops. With the help of Sysinternals ProcessMonitor, I found out that Visual Studio could not load the atl90.dll 9.0.30729.4148 from the WinSxS folder. I tried to manually copy the older atl90.dll 9.0.30729.1 with the result that Visual Studio works again. Now I call this a dirty workaround, and not a solution. Plus I still don't know the reason why the atl90.dll disappeared in the first place. So my questions: - Does anyone know of a reason why this might have happened? - Does anyone know a real solution to the problem, e.g. a Microsoft download that includes the atl90.dll in the correct version 9.0.30729.4148 that installs into WinSxS? Some details: - WinXp SP3 - missing DLL: C:\WINNT\WinSxS\x86_Microsoft.VC90.ATL_1fc8b3b9a1e18e3b_9.0.30729.4148_x-ww_353599c2\atl90.dll - workaround DLL: C:\WINNT\WinSxS\x86_Microsoft.VC90.ATL_1fc8b3b9a1e18e3b_9.0.30729.1_x-ww_d01483b2\atl90.dll - manifests in WinSxS seem to be alright, but unfortunately all point to the missing version 9.0.30729.4148 Thanks, Markus

• Issues with creating USB bootable Mountain Lion

  - by Sidd

  I am trying to set up a triple boot Windows 8, Mountain Lion, and Ubuntu. I am stuck though. I have got Windows 8 on a partition, and I am trying to get Mountain Lion on there at this point. I installed a VMware with a Snow Leopard 10.6.2 image on the Windows 8 platform. I used the disk utility in this program in order to get Mountain Lion on there. This is what i did specifically: I got the installesd.dmg. I 'mounted' that file or whatever you call it, and out came something along the lines of "Install Mountain Lion OS x" (something like that - it was like a submenu under the installesd.dmg in the disk utility). I got my PNY 8 gb Attache Flash Drive and went to the Erase tab of disk utility. I erased it using the Mac OS Extended (Journaled) setting and called it "Mac". I went to the Restore tab, dragged "Mac" into destination, and dragged "Install Mountain Lion OS x" to the source. Everything seemed to go well, but it didn't. When trying to boot from the flash drive (and yes, I set the BIOS correctly), it skipped it, and loaded Windows 8 normally as if nothing was plugged in. When I try looking at the flash drive in windows 8, it comes up as a 200 mb capacity drive labeled "EFI" with nothing in it (remember, it was 8gb in the beginning). I downloaded Plop Boot Manager, but it did not recognize a USB being plugged in. Does anyone know how I could fix this?

• Eclipse grinds to a halt when building workspace

  - by Chris Thompson

  Hi all, This is a bit of a vague question because, frankly, I don't even know where to begin diagnosing the issue. My eclipse (Galileo) installation grinds to a complete halt when it's building the workspace -- to the point where I can't even type. I know the Android SDK I have installed is a major culprit because I can watch the memory usage go through the roof (through the built-in heap monitor) when the Android SDK content loader starts up. Every time I save a file though, the program just stops. The message at the bottom of the screen says Building workspace (74%) and sits there for about 30 or so seconds before completing and returning the performance to normal. I have a few other plugins installed (Maven, SVN, etc) but I'm assuming the main issue is Android. Has anybody had similar issues or any luck correcting this sort of problem? If there's anymore information you think would be helpful, just let me know...I didn't want to do a core dump on this question... I'm running it on Windows 7 64-bit for what it's worth. Thanks! Chris

• iPhone Remote with iTunes Library via VPN

  - by sudo work

  Alright, so I'm currently behind a network router (not under my control). The router performs NAT and somehow prevents a computer from scanning other nodes. At least, you're unable, in this instance, to locate an iTunes library. You can, however, communicate with a node's open ports if the local IP address is known, as well as the port. I haven't actually tried port scanning a specific IP using nmap or another tool yet. So I've tried one solution to remove the contribution of the router entirely (to verify that it works without the influence of the routers). I set up an access point using my iPhone and tethered my computer (with the library) to it. From here, I was able to pair my library and the iPhone Remote application. Control of the library was normal as well. This solution is not ideal, however, because I am actively using bandwidth with my computer and cannot afford to be tethered to my 3G connection. A viable solution for me is to use a common VPN connection, which I have set up on a Ubuntu (Intrepid) server that is remote. Both my computer and iPhone are able to access the VPN via PPTP. The server is setup with PPTPD as the VPN-server; I'm using IPTables to perform IP masquerading and forwarding traffic. I however, still cannot connect the library to the phone. I can however, see both devices on the VPN subnet (192.168.0.0/24). SSH'ing and such works fine. What settings on the VPN server must I change to get this to work? Also, how can I assign static IP addresses to various PPTP clients based on MAC addresses?

• Printer deployment via Group Policy not working on a single system

  - by Aron Rotteveel

  One of my coworkers just got a new laptop running Windows 7 Pro x64. We use a GPO to deploy the printers to every system, but for some reason it is not working on this system. I have been breaking my head over this for the past 3 hours now without any result. The strange thing is that gpresult /H seems to indicate that the GPO did run. The hardware: Laptop: Windows 7 Professional x64 Print server: Windows Server 2008 x64 R1 HP Color LaserJet 2605dn HP LaserJet P2015 Driver packages on server: HP universal printer driver PCL5, both X86 as X64 Oddities and other info: GPO working flawlessly on every other system, including my own Windows 7 Ultimate X64 laptop gpresult /H shows the GPO being ran Windows Firewall completely disabled on the new laptop Below is the output for gpresult /H (in Dutch sadly, but I think you'll recognize it): Beleidsregels Windows-instellingen Printerverbindingen Pad Dominerend groepsbeleidsobject \\Server2008\HP Color LaserJet 2605dn Printers \\Server2008\HP LaserJet P2015 Printers Beheersjablonen Beleidsdefinities (ADMX-bestanden) opgehaald van de lokale computer. Configuratiescherm/Printers Beleid Instelling Dominerend groepsbeleidsobject Beperkingen van point-and-print Uitgeschakeld Printers Like I said, I have been trying to figure this out for the past few hours or so without any result, so you are my last hope. Any help is appreciated.

• remote telnet and email

  - by Mustafa Ismail Mustafa

  This issue has been occupying my work for the last few days and I will be understating when I say its driven me up the blasted walls. Essentially, I can ping and tracert the domain jnrcs.org and the subdomains mail.jnrcs.org and mail.jordanredcrescent.org. All three mentioned point to ip address 212.38.147.97. About 4 days ago, when we registered the domain "jnrcs.org" suddenly all external connection to the mail server from outside was lost. Not just mail, but other http based port-forwarded or natted services (such as camera surveillance and pbx services). I tried good old telnet (I'm a linux user) and I get the following output: telnet> o mail.jnrcs.org 25 Trying 212.38.147.97... telnet: Unable to connect to remote host: No route to host telnet> Tracert gives me: traceroute to mail.jnrcs.org (212.38.147.97), 30 hops max, 60 byte packets 1 192.168.1.2 (192.168.1.2) 0.869 ms 0.944 ms * 2 * * * 3 * * * 4 * * * 5 * * * 6 * 212.38.128.118 (212.38.128.118) 33.875 ms 39.187 ms 7 * * * 8 * * * 9 * * * 10 * * * 11 * * 212.38.147.97 (212.38.147.97) 67.621 ms I am stumped. Other friends from all around the world can telnet no problem. What could have possibly happened to make telnet/smtp/pop/imap/http access stop? Please bear in mind I'm primarily a developer but I [am under the delusion] that I can carry my weight in IT administration :) TIA

• apache pointing to the wrong version of python on ubuntu how do I change?

  - by one

  I am setting up a flask application on and Ubuntu 12.04.3 LTS EC2 instance and everything seemed to be working well (i.e. I could get to the webpage via the publicly available url) until I tried to import a module (e.g. numpy) and realised the apache python differs from the one I used to compile the mod_wsgi and also the one I am using I am running apache2. The apache2 logs show the warnings (specifically the last line shows the path hasnt changed): [warn] mod_wsgi: Compiled for Python/2.7.5. [warn] mod_wsgi: Runtime using Python/2.7.3. [warn] mod_wsgi: Python module path '/usr/lib/python2.7/:/usr/lib/python2.7/plat-linux2:/usr/lib/python2.7/lib-tk:/usr/lib$ I have tried to set the path in my virtual host conf (my python is located in /home/ubuntu/anaconda/bin along with all of the other libraries): WSGIPythonHome /home/ubuntu/anaconda WSGIPythonPath /home/ubuntu/anaconda <VirtualHost *:80> ServerName xx-xx-xxx-xxx-xxx.compute-1.amazonaws.com ServerAdmin [email protected] WSGIScriptAlias / /var/www/microblog/microblog.wsgi <Directory /var/www/microblog/app/> Order allow,deny Allow from all </Directory> Alias /static /var/www/microblog/app/static <Directory /var/www/FlaskApp/FlaskApp/static/> Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost> But I still get the warnings and the apache python path hasnt changed - where do I need to put the relevant directives to point apache at my python version and modules (e.g. scipy, numpy etc)? Separately, could I have avoided this using virtual environments? Thanks in advance.

• Ntop monitoring - Hosts visible with no SPAN/mirroring

  - by Cory J

  I am attempting to use ntop to monitor traffic over a Cisco Catalyst switch. I was assuming that in order to see any of the traffic, I'd have to use monitor, as described here: http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a008015c612.shtml. Howver, before I did anything on the switch, I simply plugged my ntop server in and fired up ntop. To my suprise, I instantly see 3+ pages of hosts, and thousands of packets. How is ntop seeing this? I have verified that no monitoring exists on the switch (run as en): cs1.pvdc#show monitor No SPAN configuration is present in the system. My ntop server is Ubuntu 8.04, I haven't done ANY configuration, I just installed the ntop package. This is also a fresh Ubuntu install. Is there anything else on my switch besides "monitor" that might cause my switch to mirror all its traffic like this? I've tried plugging ntop into different ports with the same results. UPDATE: It appears to be more then just broadcast traffic showing up in ntop, for example, I can see when my IPs have talked to the DNS server or generated HTTP traffic. If my switch is misconfigured, can anyone point me in the right direction towards rectify this? Not a Cisco expert.
