  • Why won't apache load a symlinked file from conf.d?

    - by kdt
    I have an apache configuration file which works fine when it's placed directly in /etc/httpd/conf.d/foo.conf. However, when I move the same file somewhere else (for example, move it to /tmp/foo.conf) and then create a symlink with ln -s /tmp/foo.conf /etc/httpd/conf.d then apache fails on startup with: httpd: could not open document config file /etc/httpd/conf.d/foo.conf I've tried making the file and the symlink mode 777, and tried changing them to be owned by the apache user. It seems like apache is failing to load the file purely on the basis of it being a symlink, but I'm sure I've used symlinks successfully on other machines. Is there something I'm missing? Does apache have an option for refusing to load config files if they're symlinks? The operating system is CentOS 4.4, apache version 2.0.52.

  • How do I make a virtualised WAN?

    - by EnchantedEggs
    I want to create a virtualised WAN. As in, I want to have a couple of VMs (VBox) on one physical host machine, that exist on separate LANs, but that can talk to each other. Do I make the VMs, set them up with different IP addresses (e.g. 1.2.3.4 and 5.6.7.8) and then configure port forwarding between them somehow??? I've seen articles that set up port forwarding on port 2222, but I don't really understand why this works. How is setting up the VM to listen to port 2222 and then port forward from there to, say, port 80, any different from just telling the VM to listen on port 80 in the first place? FYI, the VMs run Ubuntu Desktop 14.x.

  • Does my Oracle DBA need root access?

    - by Dr I
    I'm currently discussing with my Oracle DBA Collegue that request a root access on our production servers. I'm not so hot to let him use the root access on our production servers. He is arguing that he need it to perform some operations like restarting the server and some other obscure arguments. The point is that I'm not agree with him because I've set him a Oracle user/group and a dba group where Oracle user belong. Everything is running smoothy and without any root permissions for now. I also think that all administrative tasks like scheduled server restart and so one need to be operated by the proper administrator (The Systems administrator on our case) to avoid any kind of issues related to a misunderstanding of the infrastructure interactions. So, I need the help of both, sysadmins and Oracle DBAs to lead me on the correct direction. If my collegue really need this rights I'll give him, but I'm just basically quite affraid of that because of security and integrity concerns. I know that my collegue is really good as a Oracle DBA and he know is work very well, but I also know that I've very few cases where a software and its admin really need root access. Once again, I'm not looking for pros/cons but rather an advice on the way that I should take to deal with this situation.

  • Name of log file where boot process is logged

    - by ant2009
    Hello, CentOS 5.3 After booting up. I am wondering what is the name of the log file that contains if all services where successfully loaded or not? For example when computer boots you get a list of start services and they can be OK or FAILED. Is there a log file where this information is kept? I had a look in the following directory /var/log/ but not sure which one will contain the informaiton that I need. Many thanks for any advice,

  • RTNETLINK answers: File exists... maybe because assigned a new mac adress

    - by steven
    I got a "RTNETLINK answers: File exists Failed to bring up eth0:1" on "ifup eth0:1". I suspect it happens because i assigned a new mac adress in my VM's network adapter. Can you tell me how to fix the issue? My configuration looks like this: # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 allow-hotplug eth0 iface eth0 inet static address 192.168.1.80 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 192.168.1.1 # Alias being connected to 192.168.10.x Network auto eth0:1 allow-hotplug eth0:1 iface eth0:1 inet static address 192.168.10.83 netmask 255.255.255.0 gateway 192.168.10.10 dns-nameservers 192.168.10.1 Why do I get "RTNETLINK answer: File exists.." suddenly? I worked with this configuration before without problems. All i did in the past is to renew the adapters mac adress. At the moment I am connected to the 192.168.10.x Network and if I do /etc/init.d/networking stop /etc/init.d/networking start then i got "RTNETLINK [...] falied to bring up eth0:1" but the strage thing is that i am able to connect to 192.168.10.83 via ssh from my host machine. But I cannot reach the internet from the debian client. I hope it is clear what my problem is, now. update if i change my /etc/network/interfaces like this then "ifup eth0" fails, too with the same error! # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 allow-hotplug eth0 iface eth0 inet static address 192.168.10.83 netmask 255.255.255.0 gateway 192.168.10.10 dns-nameservers 192.168.10.1 with verbose option enabled i got: Configuring interfache eth0=eth0 (inet) run-parts --verbose /etc/network/if-pre-up.d ip addr add 192.168.10.83/255.255.255.0 broadcast 192.168.10.255 dev eth0 label eth0 RTNETLINK answers: File exists Failed to bring up eth0. same if i type this manually: ip addr add 192.168.10.83/255.255.255.0 broadcast 192.168.10.255 dev eth0 label eth0

  • iptables ACCEPT policy

    - by kamae
    In Redhat EL 6, iptables INPUT policy is ACCEPT but INPUT chain has REJECT entry in the end. /etc/syconfig/iptables is as below: *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT Do you know why the policy is ACCEPT not DROP? I think setting DROP policy is safer than ACCEPT in case to make mistake in the chain. Actually the policy is not applied to any packet: # iptables -L -v Chain INPUT (policy ACCEPT 0 packets, 0 bytes)

  • How can I flush my ssh keys on power management activity?

    - by Sam Halicke
    Hi all, Using ssh-agent and private keys per the usual. Everything's working as normal. My question regards best practices on flushing keys from ssh-add on activity like sleep, suspend, hibernate, etc. I thought about writing a simple wrapper around those commands, but then wondered if are they even called? Or does the kernel initiate this activity directly? Are the PM utilities strictly userland? I would like this additional layer of security beyond locking my screen, etc. and was wondering if anyone else had solved this elegantly or has best practices to recommend. Thanks.

  • Apache won't follow Symlink

    - by Marvin Dickhaus
    I have a LAMP server (Ubuntu 12.10) setup on my development machine. It is a T60 modified with an SSD. The server base is in /var/www. Apache has the following config: DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews SymLinksIfOwnerMatch AllowOverride all Order allow,deny allow from all </Directory> I'm currently developing a SilverStripe CMS featured site. The folder for the server is /var/www/sfk/. The framework and all cms relavant features are in their respective folders. The only folder that need to be modified would be the /var/www/sfk/mysite folder. Because of that I want to keep the mysite folder under my home directory and symlink it into the server folder. So here is what I've done: ln -s ~/sfk/mysite/ /var/www/sfk/ sudo chgrp www-data /var/www/sfk/mysite -R ls tells me the following: /var/www/sfk (exerpt) drwxr-xr-x 3 marvin www-data 4096 Nov 16 16:53 assets drwxr-xr-x 12 marvin www-data 4096 Nov 16 16:53 cms drwxr-xr-x 29 marvin www-data 4096 Nov 16 16:53 framework -rw-r--r-- 1 marvin www-data 2410 Nov 16 16:53 index.php lrwxrwxrwx 1 marvin www-data 24 Nov 20 17:45 mysite -> /home/marvin/sfk/mysite/ -rw-rw-r-- 1 marvin www-data 514 Nov 16 16:55 _ss_environment.php drwxr-xr-x 4 marvin www-data 4096 Nov 16 16:53 themes and ls /var/www/sfk/mysite/ drwxrwxr-x 6 marvin www-data 4096 Nov 16 00:15 code drwxrwxr-x 2 marvin www-data 4096 Nov 16 11:51 _config -rwxrwxr-x 1 marvin www-data 2685 Nov 16 15:39 _config.php drwxrwxr-x 2 marvin www-data 4096 Nov 16 00:15 css drwxrwxr-x 2 marvin www-data 4096 Nov 16 00:15 images drwxrwxr-x 2 marvin www-data 4096 Nov 16 00:15 javascript drwxrwxr-x 5 marvin www-data 4096 Nov 16 00:15 templates This is literally the same setup I have on my desktop machine. The problem I have is that the mysite/ folder is just not recognized. I'm thankful for every advice I get. I'm frustrated because I'm stuck with this issue for hours.

  • Dovecot/Postfix-mysql e-mail Aliases are not correctly forwarded

    - by jo_fryli
    I recently set up Dovecot/postfix-mysql on my Debian Squeeze Server and I have a bit of a problem. When ever I send a email to an alias ([email protected] forwarded to [email protected] for example) Postfix (or Dovecot, I'm not quite sure) puts this email into a Mailbox rather than forwarding it to the real Mail-Adress. I have tested all the MySQL queries and they all behave the way I intend them to do. foobar dovecot: deliver([email protected]): msgid=<000001385b464c9a-e40af11e-3bf4-49f6-903d-1d2369f6bfb6-000000@barfoo: saved mail to INBOX master.cf main.cf Keep in mind that normal E-Mail sending and receiving works just fine! I have set up my MySQL Tables with Postfixadmin. Thanks for your help!

  • use network drives as mount points during installation?

    - by ajsie
    is it possible to use network storage locations as mount points during installation? cause i want to separate system (ubuntu) with data (personal files). eg. if i have 5 computers i don't want to recreate /home/david 5 times. so i want to mount networkdrive/home to /home in local ubuntu server. so ALL users home folders could be used and maybe also networkdrive/projects to /projects. in that way its ok if i by accident repartitioned the local ubuntu server cause all data is not there on that server, but in the data server. is separating "data" from "logic" good in this case? and is it possible? what protocol should i use for the mapping over internet? (maybe the server is in Sweden, and the data is in Norway). thanks.

  • Add user in CentOS 5

    - by Ron
    I created a new user in my CentOS web server with useradd. Added a password with passwd. But I can't log in with the user via SSH. I keep getting 'access denied'. I checked to make sure that the password was assigned and that the account is active. /var/log/secure shows the following error: Aug 13 03:41:40 server1 su: pam_unix(su:auth): authentication failure; logname= uid=500 euid=0 tty=pts/0 ruser=rwade rhost= user=root Please help, Thanks Thanks for the responses so far: I should add that it is a VPS on a remote computer, fresh out of the box.

  • How can I find all hardlinked files on a filesystem?

    - by haimg
    I need to find all hardlinked files on a given filesystem. E.g. get a list of files, each line contains linked pairs, or triplets, etc. I understand more or less how to do it, one needs to create a dictionary keyed by inode for all files/directories on a filesystem, exclude "." and ".." links, and then indodes with more than one name are hardlinks... But I hope that maybe a ready-made solution exists, or someone already wrote such a script.

  • How to run Firefox jailed without serious performance loss?

    - by Vi
    My Firefox configuration is tricky: Firefox runs at separate restricted user account which cannot connect to main X server. Firefox uses Xvfb (virtual "headless" X server) as X server. x11vnc is running on that Xvfb. On the main X server there is vncviewer running that connect to this x11vnc On powerful laptop (Acer Extensa 5220) it seems to work more or less well, but on "Acer Aspire One" netbook it is slowish (on a background that firefox is loaded with lots of extensions). How to optimise this scheme? Requirements: Browser cannot connect to main X server. Browser should be in chroot jail (no "suid" scripts, readonly for many things) Browser should have a lot of features (like in AutoPager, NoScript, WoT, AdBlockPlus)

  • Any way to program a system which automatically restores home / sql database

    I have made two shell scripts Script 1: It does all Home directory backups with name username_home_date.tar.gz Script 2: It does SQL backups of all sites every 3 hrs. username_databse_date.sql.gz Now currently if I want to restore the site, I have to copy the tar file to /home/username and then untar there with all the permissions as well and then manually import the database. Is there any way (for instance a program, system or script) that I can just select which backup I want to restore and do automatically? Maybe like a cPanel addon thing.
