  • Free space on Dedi' in CentOS

    - by Trance84
    It will sound stupid but i need to figure out how much disk space i have in my dedicated server, it runs CentOS6...the last command i issued was this [root@ks34900 ~]# df -h Filesystem Size Used Avail Use% Mounted on rootfs 9.7G 6.4G 2.9G 69% / /dev/root 9.7G 6.4G 2.9G 69% / none 1000M 288K 1000M 1% /dev /dev/sda2 914G 200M 868G 1% /home But again, stupid as it may sound... i cant figure out how much space i have in "/" folder (root) And is it possible that "/usr" have a different space (partition)?

  • openwrt uses a single interface bridge?

    - by timbo
    My understanding of bridging is that it ties together two interfaces at layer 2. I am looking at a Ubiquiti Nanostation2 running OpenWRT that has an ethernet port 'eth0' and a wifi port 'ath0'. The ethernet port (the 'wan' port) is not part of the bridge and the bridge is just a single interface. Can anyone clarify this? - seems very different to Ubuntu. /etc/config/network: config 'interface' 'loopback' option 'ifname' 'lo' option 'proto' 'static' option 'ipaddr' '127.0.0.1' option 'netmask' '255.0.0.0' config 'interface' 'wan' option 'ifname' 'eth0' option 'proto' 'dhcp' config 'interface' 'wifi' option 'ipaddr' '192.168.13.1' option 'type' 'bridge' option 'proto' 'static' option 'netmask' '255.255.255.0' option 'ifname' 'wifi0'

  • How to execute with /bin/false shell

    - by Amar
    I am trying to setup per-user fastcgi scripts that will run each on a different port and with a different user. Here is example of my script: #!/bin/bash BIND=127.0.0.1:9001 USER=user PHP_FCGI_CHILDREN=2 PHP_FCGI_MAX_REQUESTS=10000 etc... However, if I add user with /bin/false (which I want, since this is about to be something like shared hosting and I don't want users to have shell access), the script is run under 1001, 1002 'user' which, as my Google searches showed, might be a security hole. My question is: Is it possible to allow user(s) to execute shell scripts but disable them so they cannot log in via SSH?

  • How would I `wget` files and then save them by date downloaded rather than filename?

    - by searchfgold6789
    My goal: To download 131 JPEGs and save them in a file name format that is relative to the date/time format rather than their file name. I have already tried things that involve changing the files' names after they have already been downloaded. However, these methods do not work because it seems like exif data is not being kept. For example: jhead -n%Y%m%d-%H%M%S *.jpg just returns a bunch of errors saying: Possible new names for for '{filename}.jpg' already exist File '{filename}.jpg' contains no exif date stamp. Using file date Usually, as in this case, I wind up with less files than I started out with. So is there some command I can pass to wget instead? I have already tried the --timestamp option with no success. (The man page is not to clear about what that does.)

  • Cannot SVN checkout when anon-access = none

    - by sKIPper76
    When I have anon-access = write Everything works fine. When I change svnserve.conf to: anon-access = none auth-access = write And uncomment password-db and authz-db AND add user in authz with rw AND put username/password in passwd, nothing works. Eclipse keeps giving me a "Cannot map the project with svn provider" error. I have given all the files under conf 777. Any ideas what's wrong?

  • Ubuntu 10.04 LTS - Dual monitor works only sometimes (ATI multi-desktop)

    - by Beres Botond
    I've been using my laptop with an external LCD monitor attached to it at work (Philips 201E). And at home with a different external monitor (Samsung 2032BW). I have an ATI graphics card (HD3450), with Ati Catalyst drivers enabled and I'm using the Single display desktop (Multi-Desktop) seeting. At work I have the external monitor on the left and laptop on the right, while at home the other way around. So when I switch between the two setups, I just needed to go to Ati Catalyst Control Center, change the order of the displays, change the resolution (Home - 1680x1050, Work - 1440x900), reboot and it was all fine. But since a while it doesn't work properly anymore: At home it still works fine. At work it doesn't work. Sometimes it works for some reason, after a few resolution/setting changes in ACCC and reboots... it's very strange and annoying. With the home monitor I can see the whole bootup process on both monitors (laptop + LCD) and it always just works fine. With the work monitor on the external LCD monitor I just see "No video input" until I get to the login screen, then it shows up there as well. But after login it will either: Flicker a few times, but then work OK. Or (more often) Flicker once and then go back to "No video input" again. I usually end up rebooting a few times until it works. Does anyone have any idea for fixing it? This is my xorg.conf currently: Section "ServerLayout" Identifier "amdcccle Layout" Screen 0 "amdcccle-Screen[6]-0" 0 0 Screen "amdcccle-Screen[6]-1" 1280 0 EndSection Section "Files" EndSection Section "Module" Load "glx" EndSection Section "ServerFlags" Option "Xinerama" "off" EndSection Section "Monitor" Identifier "0-LVDS" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "PreferredMode" "1280x768" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" EndSection Section "Monitor" Identifier "0-CRT1" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" Option "PreferredMode" "1440x900" EndSection Section "Device" Identifier "Default Device" Driver "fglrx" EndSection Section "Device" Identifier "amdcccle-Device[6]-0" Driver "fglrx" Option "Monitor-LVDS" "0-LVDS" BusID "PCI:6:0:0" EndSection Section "Device" Identifier "amdcccle-Device[6]-1" Driver "fglrx" Option "Monitor-CRT1" "0-CRT1" BusID "PCI:6:0:0" Screen 1 EndSection Section "Screen" Identifier "Default Screen" DefaultDepth 24 SubSection "Display" Virtual 2560 1024 EndSubSection EndSection Section "Screen" Identifier "amdcccle-Screen[6]-0" Device "amdcccle-Device[6]-0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection Section "Screen" Identifier "amdcccle-Screen[6]-1" Device "amdcccle-Device[6]-1" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection

  • Out of disk space on 4GB partiton yet it's only using 2GB

    - by Camsoft
    I'm running Ubuntu and have had a problem where the root partition has run out of disk space. When I perform df -h I get the following: Filesystem Size Used Avail Use% Mounted on /dev/sda6 4.6G 4.5G 0 100% / Yet there are only 2GB of files actually using up this partition. I then ran the following df -i and I get the following: Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda6 305824 118885 186939 39% / I have no idea what the -i flag does but it clearly shows that only 39% is used. Can anyone explain where my disk space has gone?

  • Connecting to server from remote machine

    - by Jannat Arora
    I wish to connect my machine to a server in some other city. For doing the same I am using the following command: mstsc -v ip_address_of_server remote desktop can't connect to remote computer for one of these reasons: 1) Remote access to server is not enabled. 2) Remote computer is turned off 3) Remote computer is not available on network. Make sure remote computer is turned on and connected to the network, and that remote access is enabled. As per previous posts I need to turn off my client computers firewall..which I have...but still it gives me the same message. Can someone please please help me out...so as to how i may resolve this?? I am really new to networking, etc. Also when i am pinging: ping ip_address_of server I am getting the following response: Reply from ip_address_of_server: destination host unreachable Also I did try on ubuntu with rdesktop...still its not been able to connect with it. Also i know there are other people who are able to connect their machines with the server remotely. So i guess its not working for me only. Also when I accessed the same machine through LAN I was able to do so.

  • How to tell if PAE is hurting me?

    - by James
    I have a couple of servers with 20-30 GB RAM that are running (a variant of) RHEL4. They are currently running the SMP i386 kernel, not x64, not even the hugemem kernel. This means LowMem is confined to < 1G, and thus dentry_cache and ext3_inode_cache to 100M or so each. How can I tell if this is a problem? Here's a typical vmstat report while it's compiling some Java: $ vmstat 10 procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 1 1 0 19493816 394740 922420 0 0 1058 2292 1491 1020 6 3 80 12 2 1 0 19519480 395244 850156 0 0 1179 1412 1329 1195 9 4 75 12 1 1 0 19557368 392616 828344 0 0 1783 1680 1498 1756 14 5 72 9 I don't like the way bi is nonzero when there is so much memory free. I imagine slabtop could point more directly to the problem but I don't really understand how to interpret its output.

  • How to install Apache 2.4.3 on Ubuntu 12.04

    - by SFox
    I have a clean, fresh OS of Ubuntu 12.04 on my VPS. My goal is to install WordPress. I want to install the latest version of Apache (2.4.3) but I'm encountering two problems. I'm following instructions like this & this. Both produced the same errors. The first I encounter after running "./configure --prefix=/usr/local/apache2 --with-included-apr --with-included-apr-util " the system says "It must specify an install prefix, a build directory, or an apr-config file" The second I encounter immediately afterwards, when I attempt to run make or make install. "No targets specified and no makefile found. stop." I honestly have not been able to find a solution for either, and I'm now looking for some help from the community. Any help would be greatly appreciated.

  • Syntax Error when setting up Domain Alias

  • I had a power outage. Now MySQL's lock file won't go away. What do you suggest?

    - by jasonspiro
    I do freelance IT consulting for various clients, both in Toronto, Canada, and worldwide. A client recently experienced a power failure. Now they've been having various problems with a Slackware 12.0.0 machine which also acts as a DNS server. One problem is that they can't log into phpMyAdmin. I tried stopping and restarting MySQL. But even when MySQL is stopped, the lock file stays around. jasonspiro@cybertron:~$ sudo /etc/init.d/mysql stop Shutting down MySQL. SUCCESS! jasonspiro@cybertron:~$ sudo /etc/init.d/mysql stop ERROR! MySQL manager or server PID file could not be found! jasonspiro@cybertron:~$ sudo /etc/init.d/mysql status ERROR! MySQL is not running, but lock exists jasonspiro@cybertron:~$ ls -l /var/lock/subsys/mysql -rw-r--r-- 1 root root 0 2012-07-05 16:18 /var/lock/subsys/mysql Why is MySQL's lock file hanging around despite the fact that MySQL isn't running? Can I simply stop MySQL, delete the lock file, and start MySQL again? Are there any other steps that I should take next, or nothing?

  • SLES AutoYaST Script Validity Verification

    - by Xerxes
    Does anyone here write their own customized AutoYaST scripts for building SLES servers? I'm not talking about generating them with yast2 autoyast. If so, have you found a way to verify the syntax? xmllint is good as far as telling you that the XML syntax is valid, but with an upto date DTD, it can't tell you anything more, and the shipped DTDs are out-of-date. I've opened a ticket with Novell on this, but who knows when and what I'll hear back.
