  • Permissions issue on Fedora with separate home partition

    - by Tres
    I am running Fedora 12 and I've setup a partition separate from my root partition to keep shared files and home directories. Now, I've been having permission issues where it says the user cannot chdir into their home directory (/files/home/*). Now, I fixed this originally by chmodding / to 0755 and the home directories also to 0755. And yes, the user is the owner:group of their home directory. Now get this, I didn't change a thing, rebooted, everything still works. Great, right? I boot the server up a day later, and now same ol issue. This is a home server that wasn't on at all at any point in between the working state and non-working state. Also, nothing else was modified. Any ideas? Thanks!

  • Ask filesystem if it is mounted

    - by Brian
    How can I see if a (ext3) filesystem is mounted by asking the filesystem directly (i.e. the same way that the system does when it boots and sees that it was not unmounted cleanly)? Checking the output of mount is no good because the filesystem might be mounted by a virtual machine. I know I can run fsck and it will abort if the filesystem is mounted, but I don't need to actually check the filesystem.

  • Bugzilla not sending emails, even to the test file?

    - by donutdan4114
    I have installed and setup Bugzilla3 for my domain. Everything is working properly except for the email functionality. The server uses Postfix, and that works for my PHP application, and command line. In Bugzilla, I have tried setting the mail_delivery_method to 'test', and nothing shows up in data/mailer.testfile, it is completely blank... I have no idea where to go from here, any ideas on what to try next?

  • When using autoproxy, how can you see the proxy configuration?

    - by zr
    I set the global settings of the machine to use an autoproxy configuration script. e.g. http://autoproxy.mycompanydomain.exe:8080, but still there are some network apps that require an explicit proxy setting. I assume that this is because those apps don't know how to access the global proxy settings. How can i see the global proxy settings that were configured automatically so i can copy them to the settings of these troublesome apps?

  • Redirect all ports to my server in a simple way

    - by Dorian
    I have a server with SSH access (on port 22 and 443). My ISP block everything except ports 80 and 443. I there a simple way to make everything go to my server (via SSH) then return the response via the same SSH connection, but in a way I can use all the ports in my client. Like : Me ? SSH connection ? My server ? request ? Server ? My server ? Me It's like a VPN but I don't have any port available for a VPN (443 is already taken by SSH).

  • Squid 2.7.6 not honoring ACL rules

    - by peppery
    Hello there, I have a /24 block of IP addresses assigned to a single server that I have been attempting to install Squid on an Ubuntu server machine. All of the IP addresses are set up correctly (aliases of eth0) in /etc/networking and work as they should be, using cURL I can specify an interface and it goes out on the correct address as it should be. I would like Squid to take the incoming IP address the request was sourced to and proxy the request out on the same IP (e.g incoming 123.123.123.1:3128 - 123.123.123.1, .2 - .2, etc) and have set up these ACL rules in /etc/squid.conf acl ip1 myip x.x.x.1 tcp_outgoing_address x.x.x.1 ip1 acl ip2 myip x.x.x.2 tcp_outgoing_address x.x.x.2 ip2 acl ip3 myip x.x.x.3 tcp_outgoing_address x.x.x.3 ip3 and so on, as this seems to be the only way to do what I want (from research). However, after much frustration, Squid seems to be ignoring these rules and sending requests out on the default interface. Does anybody have any suggestions? Thanks.

  • 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.

  • Grub File Stolen ( WINDOWS and OpenSus )

    - by NESIRSUSEJ
    I have a problem with my computer. I installed OpenSus on my external, and I still have Windows on my HDD. OpenSus took the Grub file and placed it on my external, so now I have to open OpenSus to open Windows. I never got a Windows CD when I bought my computer ( I live in South Africa :) ).... I want to install Ubuntu 12.04 on my external, but then I will have to format my external in which case I will lose the Grub file causing me to lose Windows, which I can't afford to do... yet. Does anyone have an idea what I can do?

  • is there a way to tail a log from remote server without using any user credentials?

    - by suhprano
    I run a script tailing a log in a remote server, like so: ssh userx@someip tail -f /data/current.log|python2.7 monitorlog.py There are dependencies and service requirements that disallows me to run the script off the remote server. (DB, ACLs, and path to another service is uses) Is there a way I can tail and monitor a log without using the ssh userx@someip? I thought about generating RSA keys but I think you still need a user to ssh.

  • Is there a proper way to clear logs?

    - by John H.
    I was wondering if there was a proper way to clear logs in general? I'm new to Ubuntu and I'm trying to set up Postfix. The log in question is /var/log/mail.log. I was wondering if there was a correct way to clear it, rather than me going in it and deleting all the lines and saving it. I find that sometimes errors don't get written to it immediately after I clear the log and save it. Side note: I'm having trouble setting up Postfix and am trying to make it easier for me to read the logs hoping it can help me out, instead of having to scroll all the way down.

  • Redirect websockets to port?

    - by DigitalMan
    So, I've got a WebSocket server in C++, that is a completely stand-alone entity - handles header parsing, receiving, sending, all of it on its own, listening directly to the port. Problem is, it needs to run on a server alongside Apache, and that's a bit of a problem. Now, there was a solution here to a similar issue involving mod_proxy, but I'm hoping I can intercept and redirect WebSocket communication before Apache even knows about it, possibly with iptables. So the question is, is it possible to direct traffic bound for chat.mysite.net to a WebSocket server on, say, port 8080, while anything else headed to mysite.net proceeds as expected to Apache?

  • 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.

  • how to find out what is causing huge dentry_cache usage?

    - by Piavlo
    Note that inode_cache & ext3_inode_cache slabs are very small compared to dentry_cache. What happens is that slowly and steadily the within a week dentry_cache grows from 1M to ~5-6G Then I need to run echo 2 > /proc/sys/vm/drop_caches && echo 0 > /proc/sys/vm/drop_caches This started to happening one day on all servers hosting some web code - the developers are saying that they have not changed anything related to filesystem access pattern around the time then the problem started. The system is centos5 with 2.6.18 kernel so I don't have any instrumentation features available th newer kernels. Any I idea how I can debug the problem? maybe with systemtap? This is a ec2 instance - so not even sure that systemtap will work there. Thanks Alex
