  • Increase text size in Ubuntu 10.04 due to having large resolution/monitors

    - by Sridhar Ratnakumar
    I have 24" dual monitors with 1920x1080 resolution on both of them. Consequently the text appears so small. I use the following text-intensive applications frequently: Web browser (Google Chrome) IDE (Komodo) Terminal (Gnome Terminal) Email (Thunderbird) I can configure text size on IDE, Terminal and Email. But for Chrome, it is not a good idea to set proportional font size because often one wants to see the entire (not just proportional fonts) site to be zoomed. So I am asking: Is it possible to increase DPI in Ubuntu (much like on Windows) so as to increase the text size across all apps? OR Is it possible to set permanent 'zoom' in Google Chrome, using a third-party extension maybe? I am using Ubuntu 10.04 (Lucid Lynx)

  • Cannot connect to postgres installed on Ubuntu

    - by Assaf
    I installed the Bitnami Django stack which included PostgreSQL 8.4. When I run psql -U postgres I get the following error: psql: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"? PG is definitely running and the pg_hba.conf file looks like this: # TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only local all all md5 # IPv4 local connections: host all all 127.0.0.1/32 md5 # IPv6 local connections: host all all ::1/128 md5 What gives?

But the problem is, I can't get repair my computer it took so long and nothing happened after I waited more than 2H and when I put my Windows 7 DVD to boot it charge the files then same thing happened nothing show up so I couldn't use command prompt. But when I use Centos everything works just fine the D partition i can mounted normally but C partition it shows me error and tell me to go to windows and repair it with Chkdsk command and here is where I am stuck.

  • Use inotifywait and lftp to synchronize servers

    - by KBoek
    I have two servers: Server A (CentOS), where people can upload files to (upload root is /files) Server B (Win 2008), with FileZilla FTP Server (FTP root is C:\content) I want that whenever a file is uploaded to Server A, to any subfolder under /files, the file is automatically copied to the exact same subfolder on Server B. Thus, if a user uploads "flowers.jpg" to /files/photos/12345/ then the file must be copied over FTP to C:\content\photos\12345 So far I have this bash script, it does copy the files to server B, but all files are placed in C:\content, and not in the corresponding subfolders. Who can help me find the correct syntax? #!/bin/bash cd /files inotifywait -q -r -m -e close_write,moved_to . --format %w%f | while read FILE; do lftp -e "put $FILE; exit" -u user,password -p 2121 ftp.server-a.com done

  • Simultanious process mysteriously ending

    - by Matt
    I'm trying to run a large air quality model, written in FORTRAN, setup with bash scripts, and run in a work queue (slurm.) The first part of the modeling is to run an "entry" model, this runs with MPI in the work queue but only on one process. At one point in the logs, there's a mysterious FORTRAN STOP, and then later the model fails because something wasn't set up properly. This FORTRAN STOP isn't from the main process, which continues running. This is a huge model, but as far as I know there should not be any other processes running at the same time. It consistently fails at the exact same spot. (I can move it by adding debug, but the debug is in the main process) How can I determine what this process is? I've tried added a call to strace -feprocess $SHELL in the run script, but I'm new to this, so if it has offered any info, I haven't been able to use it yet. The is no trace output around the FORTRAN STOP. The whole process occurs so fast that I can't seem to observe it by using ps. Is there a way I can somehow monitor all the processes being initiated from the time the work queue starts? Or some other way I can figure out what is failing? This is running on CentOS 6.4, with Slurm, compiled with PGI 13.

  • Can a faulty DNS record prevent networking?

    - by Bob
    My server's network interfaces are not available anymore since yesterday evening. I didn't change anything, but I added a new DNS-record shortly before. Unfortunately, the web interface I used to add this DNS record escaped some characters, so I've got a faulty DNS record: example.com 86400 IN TXT "\"v=spf1 mx a -all\"" However, this is the only unusual thing I could notice about this. Is it possible that the \-characters in my DNS record are confusing for some routers? Or could it be the system itself which is confused by this (it's a Debian Lenny system). Unfortunately, I can't quick-test it because of the long TTL of the record.

  • Virtualized Screen Resolution

    - by Jim R
    I have a 64 bit Ubuntu 9.10 workstation with two virtualized guest OSes using KVM/QEMU. Also both 64-bit. One is Fedora 12 the other is beta of Ubuntu 10.04. The problem is that I would like to use a larger size display that is configured by default. Both guest OSes have a maximum screen resolution of 1024x768. I would like to increase this to something like 1280x900 or 1440x900. The resolution of the host system is 1920x1080. This configuration appears to be a result of the installation detecting the resolution being reported by the virtual screen during installation. The only information I have found on the subject suggests modifying the xorg.conf file in the /etc/X11 directory. Neither guest system has this file. I tried creating one by hand in the Fedora system and managed to render it completely unusable. Not a big deal as this is recently installed and can be reinstalled easily. Is what I want to do possible? If so, how do I accomplish it?

  • gitolite post commit hook to update redmine's repository

    - by eliocs
    Hello, I currently have a ubuntu server machine which has gitolite and redmine installed. Redmine accesses repository copies which are updated using a cron task. Having a cron task to pull the updates seems like an overkill is there anyway a gitolite post-commit script could execute a pull as the redmine user. My current update script looks like this: */15 * * * * redmine cd /home/redmine/repositories/support && git pull The post-commit script I guess should be similar, how can I give the gitolite user the privileges to execute the pull as the redmine user? Thanks in advance. p.s: don't have enough reputation to create de gitolite tag.

  • Connect devices plugged into Raspberry Pi ethernet to WiFi network

    - by Tom
    I'm just starting out on a mission to learn more about networking and I've followed a tutorial (http://raspberrypihq.com/how-to-turn-a-raspberry-pi-into-a-wifi-router/) to turn my Raspberry Pi into a wifi router. That worked really well so I modified it slightly so that I can use a tethered iphone for the internet connection - I just switched all "eth0" references to "eth1" (the iphone interface) and added a script to set everything up when the phone is plugged in. This setup has freed up the Pi's ethernet port so I'd like to try and take this a step further and allow devices plugged into it to connect to the network. If possible, I'd like to try adding a switch so I can connect multiple devices. I've tried fiddling around with nat & iptables with no luck so my question is, how can I connect devices on eth0 to my wlan network?

  • Home server - HP Proliant Microserver - Software and setup - OS on USB stick?

    - by Lloyd Watkin
    I've just purchased a HP ProLiant Microserver for home use. I want to set up with web server, samba shares, the usual stuff. My question is really about system setup. It has an internal USB socket so I've attempted to install a copy of Fedora 14 onto it. I turned off X/Gnome, but it still ran like a pig. I've now put the OS on one of the internal disks (250Gb, 7200rpm), but I was wondering if there was a way to utilise the internal USB to give me better power-saving allowing the hard drives to be shut down when not in use. How would you set this server up? I'd rather not go to the extra cost of an SSD right now, but if that's the best way then so be it.

  • How many users are "many users"?

    - by kemp
    I need to find a solution for a website which is struggling under load. The site gets ~500 simultaneous connections during peak time, and counts around 42k hits per day. It's a wordpress based site bridged with a vbulletin forum with a lot of contents and a fairly complex structure which makes intensive use of the database. I already implemented code level full page caching (without this the server just crashes), and configured all other caching directives as well as combining css files and the like to limit http requests as much as possible. I need to understand if there is more that can be done via software or if the load is just too much for the server to handle and it needs to be upgraded, because the server goes down occasionally during peak times. Can't access the server now, but it's a dedicated CentOS machine (I think 4GB ram, can't say what CPU) running apache/mysql. So back to the main question: how can I know when the users are just too many?

  • rsync - Exclude files that are over a certain size?

    - by Rory
    I am doing a backup of my desktop to a remote machine. I'm basically doing rsync -a ~ example.com:backup/ However there are loads of large files, e.g. wikipedia dumps etc. Most of the files I care a lot about a small, such as firefox cookie files, or .bashrc. Is there some invocation to rsync that will exclude files that are over a certain size? That way I could copy all files that are less than 10MB first, then do all files. That way I can do a fast backup of the most important files, then a longer backup of everything else.

  • What useful things can one add to one's .bashrc ?

  • How to interrupt stuck bash tab completion?

    - by codeape
    Case: A Windows share mounted using samba over a flaky VPN connection (sometimes very slow, sometimes it drops) When doing tab-completion on filenames, my bash shell can freeze up if the VPN is slow or dropped when I am attempting the tab completion. Example: $ cp myfile.zip /mnt/winbox-c/Progr<tab> key pressed here Is there a bash key I can press to get bash out of its hung state when something like this happens?

  • Creating a USB stick for installing centos 6.x using DVD1 and DVD2 iso files

    - by user250563
    First, we create 2 partitions on the USB stick that is let's say 16GB. first partition is let's say only 1GB and the second partition is the rest of what is available. after we "w" write the changes, the USB now has 2 partitions. 1 is 1GB 1 is more than 14GB so , we have... sdb1 and sdb2 now. now we need to turn these partitions into filesystems some say i should run these commands after those procedures. mkfs.vfat -F 32 /dev/sdb1 mkfs.ext3 /dev/sdb2 but some web pages recommend using: mkfs.vfat -n BOOT /dev/sdb1 mkfs.ext2 -m 0 -b 4096 -L DATA /dev/sdb2 which is it? so let's say the DVDs are called: CentOS-6.4-x86_64-bin-DVD1.iso CentOS-6.4-x86_64-bin-DVD2.iso so we make a directory: mkdir -p /mnt/dvd1 and then mount it: mount -o loop CentOS-6.4-x86_64-bin-DVD1.iso /mnt/dvd1 and i suppose we don't make a directory for dvd2 and we don't have to mount it ? at this point i do not know what should be done. but i think this step might be next: we make the USB bootable by finding the file named mbr.bin and then moving it to there via these commnad. dd conv=notrunc bs=440 count=1 if=/usr/lib/syslinux/mbr.bin of=/dev/sdb parted /dev/sdb set 1 boot on in other words we are "dd-ing it to 'sdb' not sdb1' or 'sdb2'. and then we use parted to set the boot to on for sdb so far everything looks good? here is the confusing parts.. how exactly do i move these iso files to the usb drive? EVERYTHING BELOW IS A GUESS. so at this point i should copy the folder /mnt/dvd1/isolinux to usb's sdb1 or sdb2 ? rename it to syslinux ? and then inside this syslinux folder there will be a file called... isolinux.cfg ? which should be renamed to syslinux.cfg ? and then copy the contents of /mnt/dvd1/images/* to USB's sdb2 ? but i think i am also suppose to copy and paste the both CentOS-6.4-x86_64-bin-DVD1.iso CentOS-6.4-x86_64-bin-DVD2.iso somewhere into this USB's sdb2 partition, correct ? almost like a drag and drop kind of a thing? or do they go into any folders ? centos' own web site has some instructions but those instructions do not work. http://wiki.centos.org/HowTos/InstallFromUSBkey i once got this working but things got ruined, i have to do it again and this time take notes.

    In readline(3) I should be able to map Control-Backspace to the same function as Control-W (unix-kill-rubout). Regardless of what I put in ~/.inputrc I'm unable to get this to be recognized. \C-\b: unix-kill-rubout ...for instance does not work. Can I map Control-Backspace to the unix-kill-rubout in readline?

  • How to drop all subnets outside of the US using iptables

    - by Jim
    I want to block all subnets outside the US. I've made a script that has all of the US subnets in it. I want to disallow or DROP all but my list. Can someone give me an example of how I can start by denying everything? This is the output from -L Chain INPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT tcp -- anywhere anywhere tcp dpt:ftp state NEW DROP icmp -- anywhere anywhere Chain FORWARD (policy DROP) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination And these are the rules iptables --F iptables --policy INPUT DROP iptables --policy FORWARD DROP iptables --policy OUTPUT ACCEPT iptables -A INPUT -i lo -j ACCEPT iptables -A INPUT -i eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A INPUT -p tcp -i eth0 --dport 21 -m state --state NEW -j ACCEPT iptables -A INPUT -p icmp -j DROP Just for clarity, with these rules, I can still connect to port 21 without my subnet list. I want to block ALL subnets and just open those inside the US.

  • Building a Social Networking website, should I have separate servers for certain parts of the site? [closed]

    - by Dylan Cross
    I have been working on building a social networking website, I'm pretty committed to this and I think I have something that could work out. I hope to be launching it January 1st, and so I have a question for server setup and such. Facebook has separate domain names/servers for their photos (and I don't know what else), so I would assume that by doing this it would help spread the server loads out. So I am wondering if it would make a very big difference in speed if I had my main server for basically everything, but had another server and such that the photos would be stored on and access them the same way that facebook does.
