  • GNOME Screensaver Widgets

    - by darkfalcon
    Is there a way to add widgets to a Gnome screensaver? I think this can be done with KDE 4, but I've never liked KDE very much. I'm a programmer and comfortable with writing code if needed. I'd like to be able to: See the weather and forecast Control Rhythmbox Use a flash card widget for reviewing musical concepts The reason I want these on the screensaver is that I have login restrictions. I would like to be able to do a very limited subset of activities without having to log in.

  • Installing GNU scientific library and linking to programme

    - by jack
    I am trying to install a statistical program which requires GNU Scientific Library (GSL). I have successfully installed GSL through the yum command, but my statistical program gives an error when I try to run make install. I think there is a linking problem. How can I solve it? $ sudo yum install gsl.x86_64 Installed: gsl.x86_64 0:1.15-3.fc16 Dependency Installed: atlas.x86_64 0:3.8.4-1.fc16 $ tar -xvzf prog.tgz $ cd prog $ make $ gcc -O3 -Wall -Wshadow -pedantic -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DVER32 -I/opt/local/include/ -L/opt/local/lib/ -c -o prog.o prog.c In file included from prog.c:16:0: prog.h:7:30: fatal error: gsl/gsl_sf_gamma.h: No such file or directory compilation terminated. make: *** [prog.o] Error 1

  • Bad font anti-aliasing in Ubuntu

    - by Juliano
    I'm switching from Fedora 8 to Ubuntu 9.04, and I can't seem to get it to get a good font anti-aliasing to work. It seems that Ubuntu's fontconfig tries to keep characters in integral pixel widths. This makes text more difficult to read, when 1 pixel is too thin and 2 pixels is too thick. Check the image below. In Fedora, when fontconfig anti-aliasing is enabled, fonts have their thickness proportional to the font size. Below, the thickness is different for 8, 9 and 10pt sizes. In Ubuntu, on the other hand, even when anti-aliasing is enabled, all 8, 9 and 10pt sizes have 1 pixel thickness. This makes reading larges amount of text difficult. I'm using the very same home directory, and I already checked that X resources are the same in both systems: ~% xrdb -query | grep Xft Xft.antialias: 1 Xft.dpi: 96 Xft.hinting: 1 Xft.hintstyle: hintfull Xft.rgba: none GNOME settings: ~% gconftool-2 -a /desktop/gnome/font_rendering antialiasing = grayscale hinting = full dpi = 96 rgba_order = rgb So, the question is: What should I change in the new box (Ubuntu) in order to get anti-aliasing like in the old box (Fedora)?

  • php processes owned by ppid 1 after X amount of time

    - by Kristopher Ives
    I have a CentOS server running WHM that uses FastCGI (mod_fcgid) running PHP 5.2.17 on Apache 2.0 with SuExec. When I start Apache it begins fine and serving requests. If I run ps on the terminal as root I see the php processes and they are owned by their httpd parent processes. After X amount of time - different from time to time, not much longer than a few hours typically - the server will begin spawning PHP jobs owned by the init process ID (1) Example of good listing: 12918 18254 /usr/bin/php 12918 18257 /usr/bin/php 12918 18293 /usr/bin/php 12918 18545 /usr/bin/php 12918 18546 /usr/bin/php 12918 19016 /usr/bin/php 12918 19948 /usr/bin/php Then later something like: 1 6800 /usr/bin/php 1 6801 /usr/bin/php 1 7036 /usr/bin/php 1 8788 /usr/bin/php 1 10488 /usr/bin/php 1 10571 /usr/bin/php 1 10572 /usr/bin/php The php processes running owned by (1) never get cleaned up. Why would these processes be running? We don't use setsid or anything beyond basic PHP in the code this server is running. Cheers & Thanks

  • What is wrong with my Watcher (incron-like) daemon?

    - by eric01
    I have installed Watcher this way: both watcher.py and watcher.ini are located in /etc I also installed pyinotify and it does work when I use python -m pyinotify -v /var/www However, I want to use the daemon and when I start watcher.py, I get weird lines on my watcher.log (see below).

  • iptables rule to submit packets matching a specific negative rule

    - by Aditya Sehgal
    I am using netfilter_queue to pick up certain packets from the kernel and do some processing on them. To, the netfilter queue, I need all packets from a particular source except UDP packets with src port 2152 & dst port 2152. I try to add the iptable rule as iptables -A OUTPUT ! s 192.168.0.3 ! -p udp ! --sport 2905 ! --dport 2905 -j NFQUEUE --queue-num 0 iptables throw up an error of Invalid Argument. Querying dmesg, I see the following error print ip_tables: udp match: only valid for protocol 17 I have tried the following variation with the same error thrown. iptables -A OUTPUT ! s 192.168.0.3 ! -p udp --sport 2905 --dport 2905 -j NFQUEUE --queue-num 0 Can you please advise on the correct usage of the iptables command for my case.

  • ubuntu: mumble 1.2.2 in Karmic

    - by Dan
    Karmic only has mumble 1.1.8, but if I want to connect to a 1.2 server I need to upgrade... So I would like to know how I can upgrade to mumble 1.2.2 without messing myself up for later when I upgrade to 10.04 and beyond... I just want a smooth transition into the next versions of mumble. Is there anyway to upgrade to this newer version and either keep it in the package manager or make it not interfere with the natural upgrades the program will later recieve from the package manager? Thanks, Dan

  • Empty /var/log after running cron bash script

    - by Ortix92
    I wrote a little bash script and all of a sudden my /var/log folder is completely empty except for the log I created for the bash script. This is the script I'm running every hour with cron: #!/bin/bash STL_DIR=/path/to/some/folder/i/hid LOGFILE=/var/log/stl_upload.log now=`date` echo "----------Start of Transmission----------" 2>&1 | tee -a $LOGFILE echo "Starting transfer at $now" 2>&1 | tee -a $LOGFILE rsync -av -e ssh $STL_DIR [email protected]:/users/path/folder 2>&1 | tee -a $LOGFILE echo "----------End of transmission----------" 2>&1 | tee -a $LOGFILE printf "\n" 2>&1 | tee -a $LOGFILE I want to be clear that I'm not 100% certain this is related to the empty logs folder. So if anyone could give me a pointer as to what could be going on about the reason why my log folder is empty, that'd be great.

  • Monitor open files limits, etc

    - by marcog
    We've been hitting the max open files limit on a few services recently. There are also a bunch of other limits in place. Is there a way to monitor how close processes are to these limits so we can be alerted when it's time to either up the limits or fix the root cause? On the same note, is it possible to view a log of these events so we know when a crash occurs it's because of hitting one of these limits?

  • Starting my own server - basic recommendations and questions [closed]

    - by Ilia Rostovtsev
    Possible Duplicate: Can you help me with my capacity planning? I'm planning to start my own high-performance server and then use collocation services for keeping it up and running. I'm planning to USE it for processing videos and keeping big video site up! (using FFMpeg, MENcoder and etc.) I just need recommendations on whether listed hardware is good enough and will work together well and fast enough. Do I need anything else (missed something). I remember about CPU coolers though! ;) I'm planning to use SSD drives so please tell me if it's going to work just as regular HDDs (but much faster)? Are they going to be used as RAID (is this possible for SSDs)? Here is what I would like to get: Intel ® Server System SR1600URHSR (Urbanna) or Intel® Server System SR1695WBAC 2 x Intel Xeon X5650 4 x 16Gb DDR-III 1333MHz Kingston ECC Reg (KVR13R9D4/16) 3 x (or maybe 4x) 480Gb SSD Intel 520 Series (SSDSC2CW480A3K5) Which server system would be better? Is listed hardware new/good enough and worth buying it at the moment? Should I probably take a look at something slightly more expensive but more up to date and powerful, may be? After all as software I would like to use CentOS 6 64 bit + WHM/CPanel? Any other suggestions on maybe cheaper and same/more powerful server management system but WHM? What most important points to keep in mind when starting/maintaining your own server?

Any help or suggest will be appreciated. Thanks

  • Simple NNTP clent for Ubuntu

    - by Alexander Gladysh
    I need to download a particular NNTP group. I do not need to setup any crons, put group contents in /opt and other stuff. Just run <fetch-nntp> <server> <group-name> <output-dir> and be done with it without putting a lot of garbage in the system. If that <fetch-nntp> would not fetch the same messages on the second run — fine. But I can live without it. All NNTP clients that I've looked at are trying to be a NNTP server as well. Is there something simpler that is suitable for my needs?

  • Server not sending a SYN/ACK packet in response to a SYN packet

UPDATE 1: I've set tcp_syncookies = 0 and noticed I am now replying with 1 SYN+ACK for every 50 SYN requests. The host trying to connect is sending a SYN request about once every second. PCAP FILE

  • adress-chunk: separate data stored in one collumn - into three (street, postal-code, town)

    - by zero
    hello dear community. Hello dear friends form all over the planet first of all - this is a great great forum. I like this place to share the ideas. It is so great to see such a supportive place - featuring the knowledge exchange! today i have the following thing to discuss: i want to separate the following data that are stored in one column of a calc-spreadsheet: See the following data: You see that there are the following categories:_ steet, postal-code, town All the data are stored in only one Colum; Well to be honest: i want to separate them into three colums steet, postal-code, town see the data: what can i do? note - you see that there are commas inbetween the enties: and besides this we see that we have a postal-code with four digits: that is a good thing. Perhaps we can use this as a marker that helps us to separate the data?! Perhaps See a data-sample! Here you can see some exceptions: eg. the town that has two words combinde with a "-" ... or somethims without any signs and characters... see the following... as an example: Max-Bader-Platz 1, 5620 Schwarzach im Pongau Pestalozzistraße 4, 9990 Nussdorf-Debant Schulstraße 4, 5162 Obertrum am See But i guess that this means no problem... What do you think about this? I am very very interested to get your opinion! i look forward to hear from you! regards see a snipped of the dataset - that is stored in one column -[b]Goal: [/b]i want to separate the datas into three collumns... : Schulweg 6, 9871 Seeboden Khevenhüllerstraße 45, 4861 Schörfling Franz Xaver Rennstr.18, 6460 Imst Schulstraße 4, 5162 Obertrum am See Schulweg 6, 7432 Oberschützen Pestalozzistraße 4, 9990 Nussdorf-Debant Niederndorf bei Kufstein 53c, 6342 Niederndorf bei Kufstein Hauptschulstraße 18, 2183 Neusiedl an der Zaya Seeweg 14, 5202 Neumarkt am Wallersee Europaplatz 1, 8820 Neumarkt in Steiermark Schulstraße 7, 4212 Neumarkt im Mühlkreis Schulstraße 20, 4720 Neumarkt im Hausruckkreis Bahnhofstr. 10, 4872 Neukirchen an der Vöckla Schulstraße 5b, 4780 Schärding Reitbergstraße 2, 4311 Schwertberg Europaplatz 1, 2320 Schwechat Am Schulberg 5, 3931 Schweiggers Waidach 8, 6130 Schwaz Waidach 8, 6130 Schwaz Max-Bader-Platz 1, 5620 Schwarzach im Pongau Markt 29, 2662 Schwarzau im Gebirge Hofsteigstraße 68, 6858 Schwarzach Gmundner Straße 7, 4690 Schwanenstadt Mühlfeldstraße 1, 4690 Schwanenstadt Mainsdorferstraße 18, 8541 Schwanberg Jakob Stemer-Weg 3, 6780 Schruns Obere Umfahrungsstraße 16, 2432 Schwadorf bei Wien Battloggstraße 54, 6780 Schruns Schloss-Straße 19, 5020 Salzburg Schillerplatz 2, 8280 Fürstenfeld Erzherzog-Johann-Str. 400, 8970 Schladming Schulgasse 261, 8811 Scheifling i look forward to hear from you!! regards

  • using iptables to change a destination port but keep the ip the same.

    - by Scott Chamberlain
    I am playing around with transparent proxies, The current way I am doing things is the program makes a request to a computer on port 80, I use iptables -t nat -A OUTPUT -p tcp --destination-port 80 -j REDIRECT --to-port 1234 to redirect to my proxy that I am playing with. the proxy will send out a request to port 81 (as all outbound port 80 are being fed back in to the proxy so I want to do something like iptables -t nat -A OUTPUT -p tcp --destination-port 81 -j DNAT --to-destination xxxx:80 The problem lies with the xxxx part. How do I change the destination port without changing changing the destination ip? Or am I doing this setup completely wrong, I am learning after all and constructive criticism is definitely appreciated.

  • Is there a way to do something like LVM over NFS?

    - by warren
    I realize that since NFS is not block-level, LVM can't be used directly. However: is there a way to combine multiple NFS exports (from, say, 3 servers) into one mount point on a different server? Specifically, I'd like to be able to do this on RHEL 4 (or 5, and re-export the combined mount to my RHEL 4 server). expansion The reason I pegged lvm is that I want a bunch of exported mounts (servera:/mnt/export, serverb:/mnt/export, serverc:/mnt/export, etc) to all mount at /mnt/space so that my /mnt/space on this server (serverx) as one large filesystem. Yes, I know that re-exporting is generally a Bad Thing™ but thought it might work, if there was a way to accomplish this on a newer release as opposed to an older one From reading the unionfs docs, it appears that I can't use it over a remote connection - have I misread it? More accurately, since Union FS merges the contents of multiple branches, but makes them appear as one, it doesn't seem to go in reverse: I'm trying to mount a bunch of NFS points in a merged fashion, then write to them - not caring where data goes, a la LVM .
