  • After using lvextend, I can't recover unused space

    - by Cory Gagliardi
    I needed to add more disk space to my CentOS VM, so I added another virtual disk, then used lvextend to add the space to the existing partition. The steps I followed was: echo "- - -" > /sys/class/scsi_host/host0/scan pvcreate /dev/sdb vgextend VolGroup00 /dev/sdb lvextend -l +100%FREE /dev/VolGroup00/LogVol00 resize2fs /dev/VolGroup00/LogVol00 This worked fine. I subsequently filled up the VM, then deleted most of the used disk space. However, the unused disk space was never recovered after I deleted all of the files. This will illustrate what I'm saying better: # df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 61G 32G 26G 56% / /dev/sda1 99M 20M 75M 21% /boot tmpfs 1006M 0 1006M 0% /dev/shm # pwd; du -h --max-depth=0 / 5.1G . I cannot figure out how to get the partition to see that only 5.1 GB is used. Any ideas what I'm doing wrong?

  • Getting more helpful tab completion prompts in bash?

    - by Rory McCann
    Let's say I have a directory with a few files in it like this: $ ls file1 file2 file3 And I want to do some tab completion in bash: $ cat file<tab> file1 file2 file3 I remember seeing someone doing tab completion and the shell bolded the next parts, so in this case, it would bold the 1, 2 and 3 of the filename so it'll look like this: file**1** file**2** file**3** which will tell you what you should type in next. I think this was a feature of zsh, but is there any way to get it in bash?

  • Stack , data and address space limits on an Ubuntu server

    - by PaulDaviesC
    I am running an Ubuntu server which has around 5000 users. The users are allowed to SSH in to the system. So in order to cap the memory used up by a process I have capped the address space limits using limits.conf. So my question is , should I be limiting the data and stack ? I feel that is not required since I am capping address space. Are there any pitfalls if I do not cap the stack and data limits?

  • Trouble serving vhosts when trying to set up wildcard subdomains with dnsmasq in local development e

    - by Jeremy Kendall
    I'm trying to get wildcard DNS enabled on my laptop using dnsmasq. I realize that this has been asked and answered more than once on this forum, but I can't get the solution to work for me. Steps taken so far: Installed dnsmasq Set address=/example.dev/127.0.0.1 in dnsmasq.conf Set listen-address=127.0.0.1 in dnsmasq.conf Ensured nameserver 127.0.0.1 is in /etc/resolv.conf Set prepend domain-name-servers 127.0.0.1; in /etc/dhcp3/dhclient.conf Created a vhost for example.dev Restarted apache and dnsmasq Note: example.dev is not set in /etc/hosts My vhost for example.dev <VirtualHost *:80> ServerName example.dev DocumentRoot /home/jkendall/public_html/example/public ServerAlias *.example.dev # This should be omitted in the production environment SetEnv APPLICATION_ENV development <Directory /home/jkendall/public_html/example/public> DirectoryIndex index.php AllowOverride All Order allow,deny Allow from all </Directory> </VirtualHost> The setup above will server example.dev locally without any problem. It will also serve test.example.dev, but test.example.dev returns the default apache "It works!" index.html from /var/www rather than my index.php in /home/jkendall/public_html/example/public. The solution in this Server Fault thread suggests that address=/.example.dev/127.0.0.1 would resolve my problem, but when I try to use that solution, restarting dnsmasq results in a failure with the error message dnsmasq: error at line 62 of /etc/dnsmasq.conf For grins, I moved my project over to /var/www/example and modified the vhost appropriately. I got the same result as described above. At this point I'm not sure what other steps I can take to resolve the issue. Thoughts?

  • Windows 7 Disk Management Spanned Volume vs Striped Volume

    - by Kairan
    Im looking for a reason why a person would use a Spanned volume rather than a Striped volume? If my understanding is correct Striped: Faster read/write speed than spanned, but I "assume" more wear+tear Spanned: No speed benefit like striped, but data is written sequentially and fills up Drive1 before filling up Drive2, so it saves on wear+tear Beyond that Im not sure if there is any other deciding factor on which to use. Definition found below: A striped volume uses the free space on more than one physical hard disk to create a bigger volume. Unlike a spanned volume, a striped volume writes across all volumes in the stripe in small blocks, distributing the load across the disks in the volume. The portions of disk used to create the volume need to be the same size; the size of the smallest free space included in the striped volume will determine.

    I have tried 10 different emails hosted at Google, Yahoo!, GoDaddy, and some that are privately hosted, and each time I get the following errors.

  • Debian Unstable + Postfix 2.6.5 + dkim-filter 2.8.2 issue

    - by kura
    I have Postfix installed on Debian Unstable, as the title states, the system is completely up-to-date, I have tried to get DKIM signatures working on outgoing mail using dkim-filter 2.8.2. I couldn't use the default Debian way of doing things with sockets, instead I used the Ubuntu way: SOCKET="inet:12345@localhost"` I have the following in my postfix/main.cf milter_default_action = accept milter_protocol = 6 smtpd_milters = inet:localhost:12345 non_smtpd_milters = inet:localhost:12345 All is fine except I get the following message I start DKIM in mail.log: dkim-filter[22029]: can't configure DKIM library; continuing And when it tries to sign mails I get the following error: postfix/cleanup[22042]: warning: milter inet:localhost:12345: can't read SMFIC_EOH reply packet header: Success And then dkim-filter daemon stops. I've looked through Google but found no actual way to fix this that works for me. I have this working fine on an Ubuntu server but would love to get it working on Debian too.

  • iptables DNS resolution

    - by Favolas
    I have a virtual machine with Fedora 19 acting as a router. This machine as an interface (p8p1) with the IP 172.16.1.254 that is connected to another machine (IP 172.16.1.1) that's simulating the external network. I've installed snort 2.9.2.2, applied the snortsam-2.9.2.2.diff.gz patch and installed snortsam 2.70 on the routermachine In snort.conf besides altering some RULE_PATH I believe I've only added the following line to the file. output alert_fwsam: 127.0.0.1:898/password After doing this two comands: ifconfig p8p1 promisc /usr/local/snort/bin/snort -v -i p8p1 If I ping from the external network to the router IP, I can see the info about the pings. One of the rules that I have is icmp-info.rules that as this single line: alert icmp $EXTERNAL_NET any -> $HOME_NET any (msg:"ICMP-INFO Echo Reply"; icode:0; itype:0; classtype:misc-activity; sid:408; rev:6;fwsam: src, 5 minutes;) snortsam.conf as this data: defaultkey password accept localhost keyinterval 30 minutes dontblock 192.168.1.1 # rede local rollbackhosts 50 rollbackthreshold 20 / 30 secs rollbacksleeptime 1 minute logfile /var/log/snort/snortsam.log loglevel 3 daemon nothreads # linha importante para gerar os bloqueios via iptables iptables p8p1 LOG bindip 127.0.0.1 Now I run this command: /usr/local/snort/bin/snort -u snort -i p8p1 -c /etc/snort/snort.conf -l /var/log/snort -Dq Terminal gives this message: Spawning daemon child...

  • mysqld causes high CPU load

Checked processlist: all is normal, 1 to 20 inserts or updates that last 2 to 5 sec, and about 20 process that are in Sleep Mode (maybe because the scripts don't close the mysql connection, but are they are closed in about 5 - 10 secs, I didn't make the scripts :P but the server was running fine the last 2 years, since is was made): | 15375 | root | localhost | stoc | Query | 0 | NULL | show processlist | | 79480 | pppoe | localhost | pppoe | Sleep | 4 | NULL | NULL | | 79481 | pppoe | localhost | pppoe | Sleep | 4 | NULL | NULL | | 79482 | pppoe | localhost | pppoe | Sleep | 4 | NULL | NULL | | 79483 | pppoe | localhost | pppoe | Query | 0 | init | UPDATE acc SET InputOctets="0", OutputOctets="0", InputPackets="unknown", OutputPackets="User | | 79484 | pppoe | localhost | pppoe | Sleep | 5 | NULL | NULL | | 79485 | pppoe | localhost | pppoe | Sleep | 5 | NULL | NULL | | 79486 | pppoe | localhost | pppoe | Sleep | 5 | NULL | NULL Checked raid, seemns OK: [root@db2]# cat /proc/mdstat Personalities : [raid5] [raid4] [raid1] md0 : active raid1 sdd1[3] sdc1[2] sdb1[0] sda1[1] 136448 blocks [4/4] [UUUU] md1 : active raid5 sdd2[3] sdc2[2] sdb2[0] sda2[1] 12023808 blocks level 5, 256k chunk, algorithm 2 [4/4] [UUUU] md3 : active raid5 sda4[1] sdd4[3] sdc4[2] sdb4[0] 203647488 blocks level 5, 256k chunk, algorithm 2 [4/4] [UUUU] md2 : active raid5 sda3[1] sdd3[3] sdc3[2] sdb3[0] 24024576 blocks level 5, 256k chunk, algorithm 2 [4/4] [UUUU] unused devices: <none> [root@db2]# top sees my mysqld cpu load, but nothing else seems to be wrong: [root@db2]# top top - 17:56:05 up 7 days, 3:55, 3 users, load average: 32.93, 24.72, 22.70 Tasks: 75 total, 4 running, 71 sleeping, 0 stopped, 0 zombie Cpu(s): 63.4% us, 36.6% sy, 0.0% ni, 0.0% id, 0.0% wa, 0.0% hi, 0.0% si, 0.0% st Mem: 1988824k total, 1304776k used, 684048k free, 99588k buffers Swap: 12023800k total, 0k used, 12023800k free, 951028k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 5754 mysql 19 0 236m 57m 5108 R 99.9 2.9 21:58.76 mysqld 1 root 16 0 7216 700 580 S 0.0 0.0 0:00.39 init 2 root RT 0 0 0 0 S 0.0 0.0 0:00.00 migration/0 Repaired all mysql databases, reindexed raid ...

  • changing ext4 journal data mode with remount?

    - by Amos Shapira
    I'm tweaking ext4 file system for speed, one tweak at a time. First tweak is to change from "data=ordered" to "data=writeback". To test this, I execute "mount -n -o remount,data=ordered /" but I keep getting "mount: / not mounted already, or bad option". From lots of google'ing I found many questions about similar problems and one answer circa 2001+ext3 which says that you can't change the journal mode with remount. Is this limitation still current?

  • Is Splitting IDE hdds between Primary and Secondary faster?

    - by earlz
    Hello, I'm doing RAID 0 on two IDE harddrives (yes, this is old hardware). Will the harddrives be faster if I attach them separately so that one is on the Primary IDE controller and the other is on the Secondary IDE controller? Or would it just be as good as having them both on the Primary IDE as master and slave?

  • How to tell X.org to reload input device module? (Working around suspend-to-ram crash on Acer laptop

    - by Vi
    When X.org boots up, Synaptics touchpad works well. But when I remove the module it falls back to /dev/input/mice and don't use normal driver even when touchpad is available again. Xorg.0.log: ... (II) XINPUT: Adding extended input device "Synaptics Touchpad" (type: TOUCHPAD) (--) Synaptics Touchpad: touchpad found # { rmmod psmouse && echo mem /sys/power/state && modprobe psmouse; } (WW) : No Device specified, looking for one... (II) : Setting Device option to "/dev/input/mice" ... How to tell X.org to try it's InputDevice again (without restarting X server)? P.S. rmmod psmouse is needed to prevent crashing of Acer Extensa 5220 when resuming from suspend-to-ram. Update: Found answer myself: Doing xinput set-int-prop "Synaptics Touchpad" "Device Enabled" 8 1 after reloading the kernel module reloads touchpad. Now suspend-to-ram works OK.

  • How to get AMD Catalyst working on Arch x86_64

    - by gh403
    I've got a Dell Inspiron 15R 7520 with AMD's hybrid "PowerXpress" graphics. The integrated graphics card is (if I understand it correctly) integrated with the i7-3612QM processor, and the discrete graphics card is a "Southern Islands" Radeon HD 7730M. The integrated graphics work perfectly under Arch. However, the discrete graphics don't. I have tried several different methods, and the one that seems to get me the farthest with the least effort is the AUR package catalyst-total-pxp. After installing, rebooting, and issuing the commands # aticonfig --initial # pxp_switch_catalyst amd # X X completely fails to start. The X log can be found here. I don't understand what is failing; potentially, it has something to do with the way my card is hooked up--I think it's muxless, but I really don't know. What is the matter here? Any help would be appreciated.

  • Can't get network bridging to work

    - by Antonis Christofides
    I'm trying to make network bridging to work on a Debian squeeze (I'm experimenting in order to make a QEMU/KVM virtual machine that will be visible to the outside network as if it were a distinct machine). The problem is that when I type brctl addif br0 eth0 then I lose connectivity to the network until I type brctl delif br0 eth0. More specifically, here's how my machine looks like before I do anything (essentially eth0 is listening on 147.102.160.153): root@laura:/home/anthony# ip addr show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 8c:73:6e:db:1c:1b brd ff:ff:ff:ff:ff:ff inet 147.102.160.153/24 brd 147.102.160.255 scope global eth0 inet6 2001:648:2000:a0:8e73:6eff:fedb:1c1b/64 scope global dynamic valid_lft 2591848sec preferred_lft 604648sec inet6 fe80::8e73:6eff:fedb:1c1b/64 scope link valid_lft forever preferred_lft forever 3: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN qlen 1000 link/ether 4c:ed:de:8e:44:d7 brd ff:ff:ff:ff:ff:ff 4: vboxnet0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 0a:00:27:00:00:00 brd ff:ff:ff:ff:ff:ff 5: pan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN link/ether ee:7c:88:59:d0:e8 brd ff:ff:ff:ff:ff:ff Now let me add the bridge: root@laura:/home/anthony# brctl addbr br0 root@laura:/home/anthony# ip tuntap add dev tap0 mode tap root@laura:/home/anthony# ip link set tap0 up root@laura:/home/anthony# brctl addif br0 tap0 Until here everything continues to work normally.

  • portable cross-platform WebDAV Client

    - by theduke
    I am looking for a portable application that will allow me to do this: Browse a WebDAV share and open a file. Edit the file locally. Save the file, and automatically propagate the change to WebDAV. Is there any CROSS-PLATFORM application out there that will let me do this and exists as a portable? The reason I need this functionality is that I regularily have to access files via WebDAV from public machines where I do not have the neccessary permissions to natively mount a webdav share, or to install the neccessary components.

  • Suggest methods for testing changes to "pam.d/common-*" files

    - by Jamie
    How do I test the changes to the pam.d configuration files: Do I need to restart the PAM service to test the changes? Should I go through every service listed in the /etc/pam.d/ directory? I'm about to make changes to the pam.d/common-* files in an effort to put an Ubuntu box into an active directory controlled network. I'm just learning what to do, so I'm preparing the configuration in a VM, which I plan to deploy in metal in the coming week. It is a clean install of Ubuntu 10.04 Beta 2 server, so other than SSH daemon, all other services are stock.

  • TIME_WAIT connections not being cleaned up after timeout period expires

    - by Mark Dawson
    I am stress testing one of my servers by hitting it with a constant stream of new network connections, the tcp_fin_timeout is set to 60, so if I send a constant stream of something like 100 requests per second, I would expect to see a rolling average of 6000 (60 * 100) connections in a TIME_WAIT state, this is happening, but looking in netstat (using -o) to see the timers, I see connections like: TIME_WAIT timewait (0.00/0/0) where their timeout has expired but the connection is still hanging around, I then eventually run out of connections. Anyone know why these connections don't get cleaned up? If I stop creating new connections they do eventually disappear but while I am constantly creating new connections they don't, seems like the kernel isn't getting chance to clean them up? Is there some other config options I need to set to remove the connections as soon as they have expired? The server is running Ubuntu and my web server is nginx. Also it has iptables with connection tracking, not sure if that would cause these TIME_WAIT connections to live on. Thanks Mark.

  • Alternatives to native LDAP

    - by Matt
    We've implemented an LDAP to NIS solution and have begun transitioning some systems to native LDAP binding for authentication and automount maps. Unfortunately we have a very mixed environment with more than 20 *nix environments. The setup for each variant is of course unique and has required various workarounds to get full functionality. We're now at the point where we're willing to revisit the solution and possibly migrate toward something like Likewise (http://www.likewise.org), but would like to know what others are using to solve this problem.

  • Cannot run logwatch due to Date::Manip issue

    - by Quintin Par
    I tried to run logwatch at follows [root@machine cron.daily]# ./0logwatch ERROR: Date::Manip unable to determine TimeZone. Execute the following command in a shell prompt: perldoc Date::Manip The section titled TIMEZONES describes valid TimeZones and where they can be defined. My date is as follows root@machine cron.daily]# date Thu Aug 23 06:25:21 GMT 2012 Now based on details in various forums I tried to fix this by setting /etc/timezone to “+0800” but it didn’t work My /etc/localtime points to /usr/share/zoneinfo/GMT and is managed by puppet How do I go about fixing this? I still want all my machines to be in GMT timezone. EDIT: Sadly, Both the changes are not working: [root@machine cron.daily]# cat /etc/TIMEZONE UTC Quanta’s [root@machine cron.daily]# cat ~/.bash_profile # .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/bin export TZ=GMT export PATH [root@machine cron.daily]# source ~/.bash_profile [root@machine cron.daily]# ./0logwatch ERROR: Date::Manip unable to determine TimeZone.

  • File transfer from MP3 player to computer

    - by JP
    I own an old 20GB Creative Zen jukebox (all external screws are gone on it LOL) and I would like to transfer files back to my PC to get them on my new iPod. Problem is, no matter what software I use (WinAMP, Creative Media Source or Windows Media Player), it just stops transferring files on my HD with an error message that says there is no more space on the destination folder. Problem is, there is still 320GB free. I tried lot of things like installing newer driver, latest Zen plug-in for Media Source, latest WinAMP version. Sometimes, it just works and then again, it stops working and I get this non-sense error. Restarting my PC sometime solves the issue by giving me enough time to transfer 10 or 15 more files and then I get the error again and again. Yesterday though I managed to transfer up to 3GB of MP3s on my computer before getting the error. Seems like I'm having a driver issue or a weird behavior from the player and/or the software I'm using. 3 different software can't reproduce the exact same issue by themselves so it must be something related to the driver. I can't find any post of any sort concerning such issue on old forums. Any idea?

  • Coloring The Z Shell[closed]

    - by Richard
    Because I have to stare at my command prompt all the time on my computer, it should look at least half-decent, so I am trying to get it colored. The expected outcome is as seen on this site. I have the colors I want set in my .Xdefaults file, but they of course do not color my prompt. My .zshrc is Phil's Prompt. My .Xdefaults is: *background: #121212 !black xterm*color0: #353535 xterm*color8: #666666 !red xterm*color1: #AE4747 xterm*color9: #EE6363 !green xterm*color2: #556B2F xterm*color10: #9ACD32 !brown/yellow xterm*color3: #DAA520 xterm*color11: #FFC125 !blue xterm*color4: #6F99B4 xterm*color12: #7C96B0 !magenta xterm*color5: #8B7B8B xterm*color13: #D8BFD8 !cyan xterm*color6: #A7A15E xterm*color14: #F0E68C !white xterm*color7: #DDDDDD xterm*color15: #FFFFFF *foreground: #DDDDDD Help will be appreciated.
