• Run GUI application via cronjob in Ubuntu?

  - by Christoffer

  Hi, I have a remote server running "Ubuntu 10.04 Desktop". From it I want to run a script that walks through a list of websites and captures screenshots of them. The script is working and thoroughly tested. When I SSH to the server with ssh -X user@ip-adress I can run my script by calling ./myscript.py and everything will work OK. I then modifed my crontab file and added... 59 17 * * * env DISPLAY=:0 /path/to/myscript.py ...as recommended by the Ubuntu WIKI. I can see in the /var/log/syslog that my cron job is started, but it doesn't capture any screenshots. When running env DISPLAY=:0 /path/to/myscript.py from the shell I get No protocol specified myscript.py: cannot connect to X server :0 If I ssh to the server without the -X option I only get the second row of the error: myscript.py: cannot connect to X server :0 What can I try now? More details I have run xhost +local: and checked the output of xhost to see that the option was set correctly. If I run ls /tmp/.X11-unix/ the output is X0 The server only has one screen. Thank you in advance!

• How to get uncaught PHP errors from fcgi server

  - by jason

  My web hosting company recently replaced suPHP with fcgi on my dedicated server because I needed opcode functionality. Since then I see loads of 500 errors in apache error and php error log is empty. I have no way to figure out whats the root cause. One reason I found out was time out so my hosting company changed FcgidConnectTimeout and FcgidIOTimeout to a value of 200. I believe there are no more timeout errors in my php script. My question is how do I capture PHP error before 500 internal server error page display to user? I am using Centos 5.8 server, WHM 11.34.0 (build 9), PHP 5.3.18 and Apache/2.2.23 (Unix) mod_ssl/2.2.23 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 mod_fcgid/2.3.6

• SWATCH - what am I doing wrong?

  - by Brian Dunbar

  What I want/need/desire is to log when a user logs into my FTP server. Problem: I can't make swatch work the way I should be able to. This data is logged to a file - but of course these logs are not kept very long. I can't keep the logs around forever, but I can extract data from then, analyze it, store results elsewhere. If there is a better way to do this than the following, I'm all ears. Swatch version 3.2.3 Perl 5.12 FTP: VSFTP OS (Test): OS X 10.6.8 OS (Production): Solaris From man I see I can pass contents to a command .. so I should be able to echo those values to file, do a sed/cut/uniq thing on them for stats. $ man swatch (snip) exec command Execute command. The command may contain variables which are substituted with fields from the matched line. A $N will be replaced by the Nth field in the line. A $0 or $* will be replaced by the entire line.

• How to determine what program send the packet recorded in Wireshark?

  - by Tono Nam

  I was taking some tutorials on Wireshark in order to analyze the packets sent and received when talking to a web server for purposes of learning. When I start listening/recording packets in Wireshark, there where so many packages being recorded (700 packages per minute). Is it normal to have that much traffic if I have all the programs that will cause traffic such as all browsers, log me in, dropbox, goto meeting, etc., closed? In order to try to solve the problem I am analyzing random packets. Take for instance this filter: I just selected a random IP: 74.125.130.99. So how can I know from what program those packets where created? Also how can I get more info about that communication bwtween my computer (192.168.0.139) and that server (74.125.130.99)? I just selected a random IP from the Wireshark capture. There are also other IPs that I have no idea why they are communicating with my computer. How can I figure that out?

• Finding default gateway in an openvpn environment in windows

  - by Alexander Trümper

  I need to find the default gateway in a openvpn scenario where the route output looks like that: IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 10.49.73.1 10.49.73.24 10 0.0.0.0 128.0.0.0 10.8.0.1 10.8.0.2 30 So I googled around a bit and a found this script here: @For /f "tokens=3" %%* in ( 'route.exe print ^|findstr "\<0.0.0.0\>"' ) Do @Set "DefaultGateway=%%*" echo %DefaultGateway% This works, but matches both lines in the route output. But I need to find this line: 0.0.0.0 0.0.0.0 10.49.73.1 10.49.73.24 10 So I tried to modify the findstr parameter like this: findstr "\<0.0.0.0\>.\<0.0.0.0\>" in the expectation that '.' will match for the tab between the columns. But it doesn't. It will still set DefaultGateway to 10.8.0.1 I couldn't find a clue in MS documentation either. Maybe someone knows the right expression? Thanks a lot.

• Gifsicle: How to set it to not overwrite the original GIF file if the resulting modified GIF file is larger than the original?

  - by galacticninja

  About Gifsicle: Gifsicle is a command-line tool for creating, editing, and getting information about GIF images and animations. One of its features is (from its website): Optimize your animations! This stores only the changed portion of each frame, and can radically shrink your GIFs. You can also use transparency to make them even smaller. Gifsicle’s optimizer is pretty powerful, and usually reduces animations to within a couple bytes of the best commercial optimizers. I call Gifsicle through this .BAT file in the Right Click - 'Send to' Menu: @echo off :compressFile "C:\Programs\Compression Scripts\gifsicle\bin\gifsicle.exe" --batch -V -O3 %1% echo. echo. SHIFT if exist %1% goto compressFile PAUSE This animated GIF file, however: http://i.minus.com/i7WdodY5Zwot3.gif, when its compression is optimized with Gifsicle with the above commands, results in a larger-filesized GIF file. Gifsicle overwrites the original GIF file with the resulting larger-filesized GIF file. Initial filesize: 7.57 MiB (7,942,886 bytes). After running through the above commands with Gifsicle: 7.64 MiB (8,017,622 bytes). Is there a way to prevent Gifsicle from overwriting the original file if its output file is larger than the original file, while still overwriting the original file if the output file is smaller? Details: OS: Windows 7 Gifsicle version: 1.63, from the binary provided here: http://www.lcdf.org/gifsicle/ Gifsicle manual

• Generic/Text Printer on Windows 7 not prompting for file name

  - by Trevor Tippins

  Hope someone can shed some light on this. I am downloading reports from an AIX-based system by directing them to a TT printer which the terminal emulator (MultiView 2000) intercepts and directs to the default printer on the local system. This local printer is configured as a vanilla Generic/Text printer attached to a FILE port. When I print from AIX, the output is spooled down and the local printer prompts for a file name into which to save the file...but not under Windows 7. This has worked fine for many years, on both Win2K and WinXP. However, on Windows 7 the output gets spooled as a file into spool\PRINTERS (and looks as expected) but the print job then hangs with a status of "Error - Printing" and never prompts for a file name. I have to cancel the job. The Generic/Text printer works as expected with other applications. I have tried setting the printer to print directly rather than spooling but this only serves to hang the terminal session too. I've also tried to run the emulator in Windows 2000 Compatibility Mode and as Administrator in case it was something like that but with no luck. As you might expect, it does work fine in XP Mode (as long as I print to a printer defined therein and not the host's printer) but operationally this isn't going to be an option. Obviously this emulation software is a decade old (at least) and I could just cross/upgrade all the users (at a cost) but, before I do so, has anyone seen this sort of behaviour before and found some sort of fix? Remote OS: AIX 5 Client OS: Windows 7 Pro (32-bit) Printer: Generic/Text on a FILE port TE Software: MultiView 2000 (32-bit) Thanks in advance.

• Manual NAT on Checkpoint (Redirect all http requests to a local web server)

  - by B. Kulakli

  We have a proxy server in our internal network and I want to redirect all internet http requests to a web server in local network. It'll be like a Network Billboard that says "No direct connection is available. Set up your proxy etc." For example: A user starts the computer Opens the browser Tries to open www.google.com Should see web server output on local network Tries another web site on internet Should see web server output on local network Sets up proxy Tries to connect to a web site Web site should be loaded I have added a simple manual NAT rule to address translation in Checkpoint firewall but it simply does not work. Here is my address translation rule Source Destination Service T.Source T.Destination T.Service MY_PC A_GOOGLE_IP ALL ORIGINAL INT_WEB_SRV ORIGINAL Then when I ping A_GOOGLE_IP, replies come from INT_WEB_SRV, as I expected. However, when I try to connect A_GOOGLE_IP from browser (http://A_GOOGLE_IP), no replies come from SYN_SENT and falls into timeout. When I look at the firewall log of INT_WEB_SRV, I can see the incoming connection requests from MY_PC is accepted and NO denies. By the way, there is no problem to see INT_WEB_SRV (http://INT_WEB_SRV) from browser. My understanding is, my NAT rule at checkpoint NGX R60 does not include return packets. I definitely need some help.

• Linux Cups raspberry pi offload processing to server

  - by jaredmsaul

  I am interested in setting up a raspberry pi as the local end of a printing solution. In my testing the pi chokes on acting as a complete cups based print server. It seems a little underpowered for some of the ghostscipt processing and other filtering that occurs-- particularly on larger or complex documents the processing time can be 5 or more minutes. My question is can the processing be largely done elsewhere and the prepared end product of the processing chain be fed to the pi for output on the connected printer? So in this scenario any arbitrary document (html, pdf, text) is initially 'printed' on a relatively powerful machine but the output is stored in a file. This file is then grabbed by the pi and with all the heavy work out of the way easily printed using cups. I know files can be pushed through cups in raw mode but I am fuzzy on the pros and cons and the applicability in what I describe. I have tested this with pdftops creating a ps file then feeding that raw to cups and I think it works but it seems like there may be a cleaner solution. This scenario would ideally work for any number of printer types.

• Retrieve a domain name based on an IP Address?

  - by Neil Kodner

  I'm reviewing some apache logs, specifically with respect to downloaded files. I'm interested in knowing, if possible, which domain is responsible for the download, given an IP address. I've given nslookup a try and it seems to (mostly) get the job done but it returns all sorts of extraneous information. Ideally, I pass in an IP and receive a domain back. Before I write a shell script to parse the output of nslookup to capture the domain, I'd like to know if this is the best way of approaching this problem, or if there is a more tried-and-true method of doing this. Specifically, I'd like to know if an address resolves to an amazonaws.com domain. I understand that this might be difficult because EC2 machines are dynamically created and destroyed - I'd like to know if the IP addresses for AWS/EC2/EMR machines fit any sort of addressing pattern.

• Imagemagick convert with resample option

  - by coneybeare

  I am creating thumbnails from much larger images and have been using this command successfully for some time: convert FILE -resize "64x" -crop "64x64+0+16" +repage -strip OUTFILE I also do some other processing that is not relevant to the question. I realized that this does not adjust the resolution at all, so if I use a 300dpi image, it ends up displaying really small on some devices. I want to resample it to 72x72 so I have been trying with this command: convert FILE -resize "64x" -crop "64x64+0+16" +repage -strip -resample 72x72 OUTFILE And expected the 64x64 image at 300dpi to be resampled to a 64x64 image at 72dpi, but instead, I am getting a very funny size and density. Here is "identify" output for the original and post-processed file WITHOUT the resample: coneybeare $ convert "aa.jpg" -crop "64x64+0+16" +repage -strip "aa.png" coneybeare $ for image in `find . -type f`; do identify $image; identify -verbose $image | egrep "^ Resolution"; done ./aa.jpg JPEG 1130x1695 1130x1695+0+0 8-bit DirectClass 1.492MiB 0.000u 0:00.000 Resolution: 300x300 ./aa.png PNG 64x64 64x64+0+0 8-bit DirectClass 7.46KiB 0.000u 0:00.000 Resolution: 118.11x118.11 And here is the "identify output for the command WITH the resample: coneybeare $ convert "aa.jpg" -crop "64x64+0+16" +repage -strip -resample 72x72 "aa.png" coneybeare $ for image in `find . -type f`; do identify $image; identify -verbose $image | egrep "^ Resolution"; done ./aa.jpg JPEG 1130x1695 1130x1695+0+0 8-bit DirectClass 1.492MiB 0.000u 0:00.000 Resolution: 300x300 ./aa.png PNG 15x15 15x15+0+0 8-bit DirectClass 901b 0.000u 0:00.000 Resolution: 28.34x28.34 So, the question is: What am I doing wrong and how can I fix it so the end result is a 64x64 cropped thumbnail image at 72dpi?

  My new win7 Acer notebook has i5 CPU with Intel HD 4000 and Nvida GT650 GPU. Obviously monitor is plugged to Intel HD. In Nvidia control panel I can configure PhysX but that doesn't help. Windows system rating shows high gaming experience and average/low windows aero experience. What does that mean? Does my laptop use nvidia for games/3d apps nad Intel HD 4000 for aero? Should I disable Intel HD in bios, but how to plug monitor to nvidia? Or should I leave everything like now because everything works as it suppose to work?

• Windows media player 12 not launching from custom program

  - by Supertrolly

  There is a program we use for testing that calls windows media player and plays a media file. The problem is that windows media player fails to load unless you open and close it before starting the program. After that the program will open it every time without a hitch but after a reboot it is lost and you must do it again. My question is what could be voilate setting could windows media player have that would be lost on a reboot? I have tried programs like Regshot to capture changes to the registry that might be delated on reboot. The code for the program is very straight forward simply calling windows media player with a parameter with the media to play. Using process montior I have determined that is is crashing shortly after the program executes it. I am at a lost on this problem as I can not find what if anything it is changing to run windows media player.

• Extracting streaming video from swf

  - by user1018733

  I am trying to speed up this video by 1.25x to 1.5x, udacity style. I tried grabbing the http://smart.if.uidaho.edu/courses/f2012/cs512/ using the Download Flash & Video Firefox plugin, but it only grabbed the swf player that streams the video. Is there any other way to download this video? (as well as future videos). As a final solution, I can use video capture software while I'm not using the computer, but I don't want that hassle and time delay if possible.

• I am trying to write an htaccess file performs authentication and redirects authenticated users to a

  - by racl101

  This is what I have so far but I can't get the RewriteCond and RewriteRule properly. RewriteEngine On RewriteCond %{LA-U:REMOTE_USER} (\d{3})$ RewriteRule !^%1 http://subdomain.mydomain.com/%1 [R,L]. AuthName "My Domain Protected Area" AuthType Basic AuthUserFile /path/to/my/.htpasswd Require valid-user This is what I mean the ReWriteCond and RewriteRule to say: "If the REMOTE_USER has a username ending in 3 digits then capture the three digits that match and for whatever url they are trying to access if it does not start with the 3 digits captured then redirect them to the sub directory with the name equal to those captured three digits." In other words, if a user named 'johnny202' is authenticated then if he's requesting any directory other than http://subdomain.mydomain.com/202/ then he should be redirected to http://subdomain.mydomain.com/202/ The only thing I can think of that is wrong is the first instance of '%1'.

• "IP May Be Forged" - Sendmail Warning

  - by Mikey B

  CentOS 5.x | SendMail 8 Can I get clarification on what exactly the warning "IP may be forged" means and what conditions cause it? I recently configured SendMail to relay email from my exchange server and it's showing that warning in the logs. The messages get delivered fine but I don't like the warnings. I originally thought that there was an inconsistency between the servername used in the EHLO statement from Exchange and the respective PTR record for the source IP for Exchange. But upon examining a packet capture, I see exchange using "EHLO domain.com" and that the source IP has a PTR of "domain.com". Maybe sendmail doesn't like that the greeting only has the domain? -M

• Dual-head monitor system Kubuntu 10.04

  - by andrii

  I have a notebook Asus V6X00V with 1400*1050 monitor(name: LVDS) and Dell Monitor 1920*1080 (VGA-0). I want to have a dual monitor system. At MS Windows everything is working fine. During the Kubuntu installation the Dell and the main notebook monitors have a right resolutions(1920*1080 & 1400*1050). But after some stage it have been changed to the 1152*864 for both. Now the right resolution is only during turning off process and when I am using the console. So it shows that system can use this resolutions. The problem is just in a settings. I am using Size & Orientation - System Settings for setting adjustment. Any option that changes resolution for any monitor or changing position(Absolute, Left Of, Right of and so on) cause the color line noise on the screens. I have tried xrandr: xrandr --output LVDS --mode 1400x1050 --pos 0x0 --output VGA-0 --mode 1920x1080 --right-of LVDS --pos 1400x0 but have received the same result. I have find out that for example the previous version of Randr(1.2, now I have xrandr 1.3) need a xorg.conf file modification to create a big virtual screen, but kubuntu 10.4 don't have xorg.conf and I don't know should I modify xorg for 1.3 version of xrandr or not. Please help me to solve this problem

• Multiheaded X.org with a single workspace-pool

  - by blauwblaatje

  I've got an idea for x.org/$randomwindowmanager in combination with a multiheaded setup, but I haven't figured out how it should work. Also I don't really know where to place the feature request. Now for the idea. I've been working with screen (wikipedia:GNU_Screen) for some years now. One thing I like about it, is the fact that I can get a multi-display mode (screen -x), so you can have multiple terminals all connected to the same screen. The fun thing about it, is that you can get 2 terminals with the same content and switch my onscreen layout, without moving the terminals. I admit, in screen it's not extremely useful, but I think for a wm it can be. Imagine this. You've got two monitors and 4 workdesks. On one workdesk I've got my IDE with code, on the second one I've got the output, on the third one I've got the documentation and on the forth one I've got my e-mail and IM clients. At one moment, I want my IDE and output on my monitors, another moment my code and documentation and Yet another moment my IM to consult a colleague and documentation or code. Finally my colleague comes to help me at my desk. I'd like it if we could both watch the same workdesk without him sitting on my lap, so I turn one monitor so he can see it better. It would be great if we could see the same thing that's on my monitor (exclude mousepointer). The thing with most WMs is that your workspaces on the two monitors are either separated or glued together. If they're separated, you can change workspaces on each monitor autonomous, but you can't exchange applications between monitors because they're different x-clients (iirc). If they're glued together (xinerama), you can exchange the applications, but when changing your workspace, the other monitors change too. So, what I'd like to know is this. Is this already possible or should I submit a feature request somewhere (and if so, where?)

• RAID degraded on Ubuntu server

  - by reano

  We're having a very weird issue at work. Our Ubuntu server has 6 drives, set up with RAID1 as follows: /dev/md0, consisting of: /dev/sda1 /dev/sdb1 /dev/md1, consisting of: /dev/sda2 /dev/sdb2 /dev/md2, consisting of: /dev/sda3 /dev/sdb3 /dev/md3, consisting of: /dev/sdc1 /dev/sdd1 /dev/md4, consisting of: /dev/sde1 /dev/sdf1 As you can see, md0, md1 and md2 all use the same 2 drives (split into 3 partitions). I also have to note that this is done via ubuntu software raid, not hardware raid. Today, the /md0 RAID1 array shows as degraded - it is missing the /dev/sdb1 drive. But since /dev/sdb1 is only a partition (and /dev/sdb2 and /dev/sdb3 are working fine), it's obviously not the drive that's gone AWOL, it seems the partition itself is missing. How is that even possible? And what could we do to fix it?

• OpenVPN + iptables / NAT routing

  - by Mikeage

  I'm trying to set up an OpenVPN VPN, which will carry some (but not all) traffic from the clients to the internet via the OpenVPN server. My OpenVPN server has a public IP on eth0, and is using tap0 to create a local network, 192.168.2.x. I have a client which connects from local IP 192.168.1.101 and gets VPN IP 192.168.2.3. On the server, I ran: iptables -A INPUT -i tap+ -j ACCEPT iptables -A FORWARD -i tap+ -j ACCEPT iptables -t nat -A POSTROUTING -s 192.168.2.0/24 -o eth0 -j MASQUERADE On the client, the default remains to route via 192.168.1.1. In order to point it to 192.168.2.1 for HTTP, I ran ip rule add fwmark 0x50 table 200 ip route add table 200 default via 192.168.2.1 iptables -t mangle -A OUTPUT -j MARK -p tcp --dport 80 --set-mark 80 Now, if I try accessing a website on the client (say, wget google.com), it just hangs there. On the server, I can see $ sudo tcpdump -n -i tap0 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on tap0, link-type EN10MB (Ethernet), capture size 96 bytes 05:39:07.928358 IP 192.168.1.101.34941 > 74.125.67.100.80: S 4254520618:4254520618(0) win 5840 <mss 1334,sackOK,timestamp 558838 0,nop,wscale 5> 05:39:10.751921 IP 192.168.1.101.34941 > 74.125.67.100.80: S 4254520618:4254520618(0) win 5840 <mss 1334,sackOK,timestamp 559588 0,nop,wscale 5> Where 74.125.67.100 is the IP it gets for google.com . Why isn't the MASQUERADE working? More precisely, I see that the source showing up as 192.168.1.101 -- shouldn't there be something to indicate that it came from the VPN? Edit: Some routes [from the client] $ ip route show table main 192.168.2.0/24 dev tap0 proto kernel scope link src 192.168.2.4 192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.101 metric 2 169.254.0.0/16 dev wlan0 scope link metric 1000 default via 192.168.1.1 dev wlan0 proto static $ ip route show table 200 default via 192.168.2.1 dev tap0

• Grayed-Out Sleep and Hibernate Options on Windows 7 After Updating Graphics Driver

  - by Maxim Zaslavsky

  I have a Gateway M275 Tablet PC, on which I've installed Windows 7 Ultimate. The laptop is quite old, so there aren't any Win7 drivers for it, not to mention any Vista drivers. Win7 has been working for some time, but I noticed that my video output wasn't working. I went into Device Manager and found that I didn't have a driver for my video card: it just recognized it as the standard one. I searched online and found an XP driver for it, released by Gateway. Device Manager accepted this driver and prompted me to reboot. After that, I noticed that my Sleep and Hibernate options in the Shut Down menu have been grayed-out. I looked online and found that many people are attributing this to display drivers, as such an old driver would surely not be compatible with the standby procedures Windows 7 uses. To make it clear: I was able to Sleep and Hibernate before updating the drivers; now, I can't. Running powercfg /a gives me, "An internal system component has disabled this standby state," for each available standby mode. Is there some way that the driver can be modified to support hibernation? The new driver fixed my video output problem, but I guess hibernation is more important for me. If not, what steps should I take to remove the driver and just leave the standard Windows one, which previously supported hibernation and sleep on this computer? Thanks in advance.

• Iptables ignoring a rule in the config file

  - by Overdeath

  I see lot of established connections to my apache server from the ip 188.241.114.22 which eventually causes apache to hang . After I restart the service everything works fine. I tried adding a rule in iptables -A INPUT -s 188.241.114.22 -j DROP but despite that I keep seeing connections from that IP. I'm using centOS and i'm adding the rule like thie: iptables -A INPUT -s 188.241.114.22 -j DROP Right afther that I save it using: service iptables save Here is the output of iptables -L -v ` Chain INPUT (policy ACCEPT 120K packets, 16M bytes) pkts bytes target prot opt in out source destination 0 0 DROP all -- any any lg01.mia02.pccwbtn.net anywhere 0 0 DROP all -- any any c-98-210-5-174.hsd1.ca.comcast.net anywhere 0 0 DROP all -- any any c-98-201-5-174.hsd1.tx.comcast.net anywhere 0 0 DROP all -- any any lg01.mia02.pccwbtn.net anywhere 0 0 DROP all -- any any www.dabacus2.com anywhere 0 0 DROP all -- any any 116.255.163.100 anywhere 0 0 DROP all -- any any 94.23.119.11 anywhere 0 0 DROP all -- any any 164.bajanet.mx anywhere 0 0 DROP all -- any any 173-203-71-136.static.cloud-ips.com anywhere 0 0 DROP all -- any any v1.oxygen.ro anywhere 0 0 DROP all -- any any 74.122.177.12 anywhere 0 0 DROP all -- any any 58.83.227.150 anywhere 0 0 DROP all -- any any v1.oxygen.ro anywhere 0 0 DROP all -- any any v1.oxygen.ro anywhere Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 186K packets, 224M bytes) pkts bytes target prot opt in out source destination `
