  • Apache logs other user read permissions

    - by user2344668
    We have several developers who maintain the system and I want them to easily read the log files in /var/log/httpd without needing root access. I set the read permission for 'other' users but when I run tail on the log files I get permission denied: [root@ourserver httpd]# chmod -R go+r /var/log/httpd [root@ourserver httpd]# ls -la drwxr--r-- 13 root root 4096 Oct 25 03:31 . drwxr-xr-x. 6 root root 4096 Oct 20 03:24 .. drwxr-xr-x 2 root root 4096 Oct 20 03:24 oursite.com drwxr-xr-x 2 root root 4096 Oct 20 03:24 oursite2.com -rw-r--r-- 1 root root 0 May 7 03:46 access_log -rw-r--r-- 1 root root 3446 Oct 24 22:05 error_log [me@ourserver ~]$ tail -f /var/log/httpd/oursite.com/error.log tail: cannot open `/var/log/httpd/oursite/error.log' for reading: Permission denied Maybe I'm missing something on how permissions work but I'm not finding any easy answers on it.

  • Installing Debian 7.6.0 on Lenovo Y50

    - by Girauder
    I was trying to install Debian on my new laptop: a Lenovo Y50 64bit running Windows 8. I got together with a friend and installed Debian in his computer first and had no problems. However I've tried to install Debian several times using the AMD64 KDE and netinst versions and accomplished nothing. First try: installed the KDE version. Grub would let me choose which operating system I wanted, but when I selected Debian it would only load the command line. Second try: Reinstalled but this time with the netinst version. I only got a black screen where I could type but nothing else. Third Try. Tried the netinst again. This time after making the partitions I got a message that said that no EFI partition was found. I ignored the message and this time it wouldn't even load Grub. only a command like interface with grub rescue or something. Not once did I get an error during the installation. What am I doing wrong? I assume the problem is I need to make an EFI partition or something like that. So why is it that during the first installations I didn't ask me for that. And if that is indeed the problem, How can I solve it? Update So the installation failed again... as predicted. Here you can find the Disk Management picture. http://postimg.org/image/433cpfkjz/ Please somebody help me. I keep getting the grub rescue thing. secure boot is disabled and legacy support is set first.

  • Is there a config value in Wine to force Enter to send CR+LF?

    - by bedwyr
    I'm pretty new to Wine and I'm trying to use an IM client which is required for my work. When I hit 'Enter' to send a chat message, the characters indicating a new line are not being correctly interpreted. Here's a basic SYN-ACK between the two of us: His view: me: SYN!him: ACK! My view: him: SYN!me: ACK!me: ACK! Is there any way I can configure Wine to handle this correctly? Please note: this is a required application and I have no way to change its configuration.

  • How to I configure a swap partition using swapspace

    - by jcalfee314
    I finally have the swapspace project installed and running (via init.d). The purpose is to have a dynamically re-sizing swap partition. I'm clueless however on how to use it. It has good documentation but just does not go into that last step. How to I configure a swap partition using swapspace? The process is probably the same for any 3rd party program that would provide a swap space implementation to the kernel. I know this was intended to run as a process because the project provides an init.d script.

  • use ubuntu from a removable drive to work both on laptop and desktop computer

    - by moragos
    my laptop, which i run ubuntu on, is getting a bit old and i find it's getting slower and slower at running applications. My desktop computer is stronger, but I can't give up on the portability of my laptop. I was thinking of installing a HD drawer for both my laptop and desktop. and when I come home just pull the HD from the laptop and plug it into the desktop. I wanted to ask if anyone have tried it or have any inputs on the idea

  • What is /usr/bin/[ ?

    - by Josh
    I was just poking around in /usr/bin and I found an ELF binary file called [. /usr/bin/[. I have never heard of this file and my first thought was that it was a clever way of hiding a program, possibly a trojan. However it's present on all my CentOS servers and seems to have no manual entry. I can hazard a guess as to what it is but I was looking for a more authoritative answer...

  • Access denied for user 'root@localhost' (using password:NO)

    - by murgatroid99
    I am attempting to install a network management package called cacti onto Ubuntu running under Windows Virtual PC. I attempted to install MySQL as it is one of cacti's dependencies. I can install and start the MySQL server, but whenever I try to access it in any other way, such as to change the password, I get the error message Access denied for user 'root@localhost' (using password:NO). I would like to know what is causing this and how to fix it. Edit: (just in case my comments are not visible) The answers from HD and Devin Ceartas did not work for me.

  • Question about conditions of vps host provide

    - by baobeiii
    Looking into buying a VPS from a company. In their terms of service it says: User may not: a) Use 25% or more of system resources for longer then 90 seconds. There are numerous activities that could cause such problems; these include: CGI scripts, FTP, PHP, HTTP, etc. So basically your only allowed to use a 1/4 of what your paying for? Anyone know if this is a standard restriction for most hosting providers? Seems a bit ridiculous but i don't know whats normal in the server world. And the weird thing is they only sell xen servers so why can't i use my allotted resources as no-one else can. Thanks.

  • Can I remove the original file while running "sort"?

    - by Spaceman
    I'm sorting a huge file, around 400 gigabytes. I'm running out of the disk space and I must do something quickly. Let's assume the original file is called original_file. So I execute (simplified) it as "sort original_file | gzip -c output_file" I use /home/tmp as a temporary dir. From what I see, there are a lot of intermediate files, like so: tmpA465 tmpB154 ... and so on. The smallest ones have size 12 megabytes. The largest have ~182 megabytes. So, it seems that the "sort" command have already split the original file into small pieces, and have sorted them, and now it is merging them into bigger parts (which will be, eventually, sorted as well). Please correct me if I'm wrong. Can I remove the original file right now without terminating the sort process? I've been waiting for a few days for that and it's important that the "sort" command will not fail and I will get the result file, finally. The OS is Ubuntu server 13.04, x64. Thanks!

  • Using cd to go up multiple directory levels

    - by Tossrock
    I'm dealing with java projects which often result in deeply nested folders (/path/to/project/com/java/lang/whatever, etc) and sometimes want to be able to jump, say, 4 directory levels upwards. Typing cd ../../../.. is a pain, and I don't want to symlink. Is there some flag to cd that lets you go up multiple directory levels (in my head, it would be something like cd -u 4)? Unfortunately I can't find any man page for cd specifically, instead just getting the useless "builtins" page.

  • Manually Editing iptables

    - by JamesB41
    I'm using CentOS. What I'm wondering is, what happens if I manually edit /etc/sysconfig/iptables and save it? Is that the definitive source? When I type iptables -L I get something that doesn't match the contents of that file. Is there a way I can just edit the chains directly without adding/removing rules one at a time? i.e. open VIM and get everything set up the way I want it and then save. Along those lines, when I do something like iptables -A INPUT , where does that go in the immediate sense? Is it not applied until I do an iptables-save? I feel like I'm just missing an a-ha moment here and I can't seem to find the answer in a search.

  • Why does changing a truecrypt password take such a long time?

    - by Alex
    I am changing the password of a truecrypt file container. This takes around 1 minute. Why? time truecrypt --text --change /tmp/user1.tc --keyfiles= --new-keyfiles= --password=known --new-password=known --random-source=/dev/null" If I use strace I see that it basically does not do anything: it simply reads lots of random data from /dev/urandom (even if i specified /dev/null as random source) and finally changes the password: open("/dev/urandom", O_RDONLY) = 6 read(6, "\36&{\351\212\212\343\202\34\313\242\312I\326\235\245\224\300\354O)\270Q\200 \201J\227\224\311_\212\367"..., 640) = 640 close(6) = 0

  • [CentOS 4.8] nslookup resolves domains to IPs, but I can't get a response to pings to external servers

    - by Beco
    I have a fresh install of CentOS 4.8 running on an internal development server. I haven't done anything to it besides setting up sudoers and SSH. I can SSH into the server and from there resolve domains to IPs and ping internal servers, but for some reason I don't get any response from pinging external servers. The software firewall is disabled, and the problem is present with both static and DHCP-assigned network configurations.

  • How can I redirect HTTP(S) traffic to another gateway?

    - by PsyStyle
    I have a network like 192.168.0.0/15 with the default gateway set to 192.168.0.1. All the workstations of the network use this gateway for all kind of accesses to the Internet. Now I am testing a new Internet connection with another provider and for that I'm using a second gateway on the same subnet with 192.168.0.2 as IP address. I want to redirect only HTTP and HTTPS traffic to this second gateway keeping untouched the address of the default gateway set inside every workstation. How can I accomplish this task? What I have to change inside the first's gateway firewall configuration or routes? I tried with a DNAT like: DNAT loc:192.168.0.1 loc:192.168.0.2 tcp 80 but nothing worked. I use Shorewall for simplicity in configuration but I can understand even theorical answers which I will try to adapt to my case.

  • Writing directory: permission denied even though dir seems to be chmodded correctly

    I am having some trouble creating files in directory on my Ubuntu machine: I added myself to the www-data group in order for me to easily edit stuff in my /var/www dir on my development machine. stat /var/www shows the following: File: ‘/var/www’ Size: 4096 Blocks: 8 IO Block: 4096 map Device: 808h/2056d Inode: 142853 Links: 3 Access: (0775/drwxrwxr-x) Uid: ( 33/www-data) Gid: ( 33/www-data) Access: 2010-12-30 16:03:18.563998000 +0100 Modify: 2010-12-30 16:02:52.663998000 +0100 Change: 2010-12-30 16:03:13.111998001 +0100 Still, it is impossible for me to create anything below /var/www (the only way for it to work is to chmod it to 777.

  • Mac Terminal - Color Co-ordinated

    - by Biscuit128
    I would like to create a couple of short cuts on my iMac which ssh on to my dev box and on to my prod box. I would like my dev connection to use the settings something similar to home-brew (green text black background) and my prod connection to use red text black background) - How can this be configured so that this is possible. Would I need multiple bashrc files one for prod and one for dev and source individually? If this is the case, how can i get the profiles to be sources as soon as i double click the shortcuts? Thanks
