  • ubuntu and laptops or mini-laptops

    - by doug
    Hi here I'm planing to buy a laptop or mini-laptop and use a Ubuntu OS on it. The thing is that i really need it to use it many hours on batery mode. I'm thinking that i'll have troubles in finding the right rivers and my batery to be waisted. What other problems can I have? Also, I wana use the laptop or mini-laptop outside/outdoor. What display technology is most recommended for that?

  • [Ubuntu]df Total size is not correct compared with the size of the disk

    - by John John
    I'm running Ubuntu Squeeze and on one of the partitions df is showing the Total size as 335G: Filesystem Size Used Avail Use% Mounted on /dev/sdb 335G 225G 94G 71% /mnt However in the past it was showing as 360GB (which is the actual size): fdisk -l /dev/sdb Disk /dev/sdb: 365.0 GB, 365041287168 bytes lsof +L1 does not return anything (and anyway if this would be the case the Total space should not be affected.) On this partition I'm writing (and deleting) a lot of files and this happened before in the past, but problem solved by itself.

  • How to install Several Tomcat instances on Ubuntu?

    - by tputkonen
    I need to have two instances of Tomcat 6 running on Ubuntu 10.04. I know it should be doable pretty simply by something like: copy /var/lib/tomcat6 to /var/lib/tomcat6-2 modify ports in /var/lib/tomcat6-2/conf/server.xml copy /etc/init.d/tomcat6 to /etc/init.d/tomcat6-2 modify /etc/init.d/tomcat6-2... ...but my problem is that I'm unsure what I should modify in /etc/init.d/tomcat6-2. Chaging the NAME in the beginning of the file clearly is not enough.

  • Ubuntu home directory selectively reverting

    - by Zurahn
    This is perhaps the most bizarre problem I've ever come across, but my home directory in Ubuntu 9.10 seems to be occasionally reverting to a previous state. For example, I'll change a setting in Opera (whose settings folder is in my home directory), then upon subsequent restart, may or may not have reset to what it was previously. This happens with all programs with settings in the home directory. I have the Kubuntu desktop downloaded as well, so I am using KDE4. Any ideas?

  • How to install Ubuntu, Windows XP and Windows 7 from scratch as triple-boot system

    - by simon
    I'm currently running Windows XP, but have ordered Windows 7. I want to keep Windows XP on a separate partition, and install Ubuntu as well. In which order should I install the OSs, and is there anything differing from an ordinary single-system install I should keep in mind? For example, does the order of partition make any difference? If I want to have the system drive as "C:" drive in both Win XP and Win 7, what should I do?

    - by James Ward
    I have an Ubuntu 10.10 EBS boot server on EC2. There are new updates available for it: linux-image-virtual linux-virtual Is it even ok to upgrade those packages on an EC2 server?

Will my instance be able to be rebooted?

  • how to upgrade to openoffice 3.1.1 on ubuntu jaunty

    - by BD at Rivenhill
    I need to read some .docx files and the standard 3.0.1 version of OpenOffice writer that comes with Unbuntu 9.04 just ain't handling it. I tried the instructions from the following site: http://news.softpedia.com/news/How-to-Install-OpenOffice-org-3-1-on-Ubuntu-9-04-111105.shtml, both the GUI steps in the main article, and a scripted version in one of the comments, but my system never seems to do the partial update, and the OpenOffice version is unchanged after I uninstall and reinstall it from the command line. Has anybody had similar problems?

  • Ubuntu getting wrong hostname from DHCP

    - by sam
    When provisioning new Ubuntu Precise (12.04) servers, the hostname they're getting seems to be generated from the DNS search path, not a reverse lookup on the hostname. Take the following configuration BIND is configured with the hostname, and reverse name Normal zone $TTL 600 $ORIGIN srv.local.net. @ IN SOA ns0.local.net. hostmaster.local.net. ( 2014082101 10800 3600 604800 600 ) @ IN NS ns0.local.net. @ IN MX 5 mail.local.net. my-new-server IN A 10.32.2.30 And reverse @ IN SOA ns0.local.net. hostmaster.local.net. ( 2014082101 10800 3600 604800 600 ) @ IN NS ns0.local.net. $ORIGIN 32.10.in-addr.arpa. 30.2 IN PTR my-new-server.srv.local.net. Then DHCPD is configured to hand out static leases based on mac addresses like so subnet 10.32.2.0 netmask 255.255.254.0 { option subnet-mask 255.255.254.0; option routers 10.32.2.1; option domain-name-servers 10.32.2.1; option domain-name "util.of1.local.net of1.local.net srv.local.net"; site-option-space "pxelinux"; option pxelinux.magic f1:00:74:7e; if exists dhcp-parameter-request-list { option dhcp-parameter-request-list = concat(option dhcp-parameter-request-list,d0,d1,d2,d3); } group { option pxelinux.configfile "pxelinux.cfg/pxeboot"; host my-new-server { fixed-address my-new-server.srv.local.net; hardware ethernet aa:aa:aa:bb:bb:bb; } } } So the hostname should be my-new-server.srv.local.net, however when building a Ubuntu 12.04 node, the hostname ends up as my-new-server.util.of1.local.net When building Lucid (10.04) hosts, the hostname will be correct, it's only on Precise/12.04 nodes we have the problem. Doing a normal and reverse lookup on the host and IP returns the correct result Sams-MacBook-Pro:~ sam$ host my-new-server my-new-server.srv.local.net has address 10.32.2.30 Sams-MacBook-Pro:~ sam$ host my-new-server.srv.local.net my-new-server.srv.local.net has address 10.32.2.30 Sams-MacBook-Pro:~ sam$ host 10.32.2.30 30.2.32.10.in-addr.arpa domain name pointer my-new-server.srv.local.net. The contents of the hosts file is incorrect too 127.0.0.1 localhost 127.0.1.1 my-new-server.util.of1.local.net of1.local.net srv.local.net my-new-server So it looks like when it creates the hosts file, it puts the entire contents of the DNS search path into the local address so the FQDN according to the server is the short hostname as defined, then the first domain in the search path. Is there a way to get around this behaviour, or fix this so it gets the hostname correctly? It's picking up the first part of the hostname, then the rest is wrong.

  • Websites on Ubuntu 8.04 LTS with Plesk are infected with viruses

    - by Paddington
    I am running Plesk 9.5 on Ubuntu 8.04 LTS and have about 15 websites infected with some malicious code appended to the end of java files. I have installed Clamav and it has managed to pickup the infected files which have a pattern of starting with either /*km0ae9gr6m*/ or /*gootkitstart*/ and ending with /*qhk6sa6g1c*/ or /*gootkitend*/ My Plesk panel is up to date and security patches were installed. How can I isolate the security vulnerability on the server?

  • ubuntu connect to server -> permantely mount?

    - by myforwik
    I have a system with Ubuntu 9.10 installed. I can connect to remote windows shares by using the "connect to server" under "places" menu. I can't figure out where these mount in the file system. And how can I get this to mount automatically on startup? And I can't install smbfs or anything else. I need to use only what comes on the live CD, as there is no internet connection and no way to get in packages.
