Ubuntu Servers :: Security - Creating A Photoblog On Wordpress
Feb 5, 2010
I am interested in creating a photoblog on Wordpress. Before I jump in I thought it would be wise to ask a few questions here first rather than getting into trouble and then firing absurd questions left and right. I am not very experienced regarding servers but not afraid either I was reading How-to's online reagarding installing Wordpress on Linux [url] and few questions came to mind :
1) Like any other server, does the computer that will run Wordpress have to be up and running for 24/7?
2) Since I will install Wordpress on a desktop, should I be concerned about my machine being compromised? I am not an expert on internet security so this is a big concern of mine.
3) Is it a good idea to install Wordpress on a personal desktop at all? Does running Wordpress from a different partition of the hard drive (if it is possible) help at all.

I'm trying to get wordpress to work with lighttpd and my home test server... <name>.dnsalias.org as my IP is not static... When I install wordpress ( via apt-get ) and set it up through install script like this:
bash /usr/share/doc/wordpress/examples/setup-mysql -n wordpress <name>.dnsalias.org It is accessible from outside of my network but not from local one where the sever ip is 10.0.0.200 From outside it is using correctly domain <name>.dnsalias.org but from inside when I try to use ip 10.0.0.200 from other pc on net it will not work..a s it still using <name>.dnsalias.org in all links... Also I would like to have it in <name>.dnsalias.org/wordpress as I have another test site in <name>.dnsalias.org/<test_Site> which by thee way works from inside and outside of my network.... its just wordpress ...
I have followed this guide: [URL] but its for apache... I spend whole night searching for some solution and now I'm dead tired and you are my last hope ...( ....Obi Wan Kenobi ) So does someone running wordpress in setup like I described above, if yes

I am having difficulties assigning permission for wordpress to write files. I am having problems with the permalink within wordpress and I think it might be because of the level of permission wordpress has. Currently on my system I need to set permission to 777 in order for wordpress to write to the .htaccess file.
I am running my website on a Ubuntu machine. Version 10.10 Apache2 2.2.4
However, when I leave the permission level set to 777 I still cannot get the permalink to point to the corrent page......See my discussion on this here. [URL]
I think what I need to do is change wordpress to use a user permission or a group permission and not "everyone". I would rather have wordpress setup to login as a specific user before it can write over a file.

But I can't upload files or pictures all the time.Everytime I tried to upload , it tips me : "can't create file or folder ...... . is its parents folder writable by the server?"Now it's considered as a bug.But I tried 3 methods introduced on the net . But none of them worked. They are : 1: change the folder permission to 777 , not work for me.2: change the URL to "wp-content/uploads" not "/wp-content/uploads" , not work for me.3: use full url not "wp-content/uploads" also not work.

Main purpose of this LAMP server is testing development. I would like to get this server setup up almost exactly to a T how my real web hosting server is setup. I am running 11.04 and have installed LAMP. I also installed vsftpd. I went ahead and made a symlink from /home/user/public_html to /var/www/. I login from a Windows 7 computer via CuteFTP to my Ubuntu server. I can enter the public_html directory and can create folders but the default permissions for any folder created is 700. I have tried running chmod -R 755 /home/user/public_html but this does not work. Every file or folder created now currently will take a 700 permission.
How do I make it so anything that is uploaded into this folder will be at either 755 or 775? Also what is the best practice for utilizing the /var/www directory? Should I be using a symlink to link it to my user's home folder? I have read through so many posts with regards to adding users to a group and giving this group permission and this or that I'm so confused.

I have small home atom-server on netbook (with damaged screen) with Intel Atom N450 1.6Ghz CPU and 1GB of RAM. I am looking for web server, that would not eat much resources when hosting wordpress blog (up to 50-100 readers at once in veeeeeery far future) - posts in most cases will be only text based, without big images or archives (I'm not sure if it is important).The brain of my atom-server is latest 32-bit ubuntu server, without X's, I access it from ssh console only. It is already:
- proxy gate for my internal network (squid)
- my gmail backup/IMAP (dovecot & getmail)
- file server for my internal network (samba)
[code]....

I'm installing Wordpress and I want Hosting Multiple Sites with them. For that I need modify the httpd.conf file but it's empty. Where I can make that changes? These are the changes:
1. Type: LoadModule rewrite_module /libexec/mod_rewrite.so
2. Find the <VirtualHost> section in the httpd.conf file.
3. Find a line in the <VirtualHost> section of the httpd.conf that looks like this: AllowOverride None
3. Replace that line with this line: AllowOverride FileInfo Options
4. On a new line, type ServerAlias *.[URL].
5. Save the httpd.conf file and close it.

I have Webmin installed on an Ubuntu server. I currently have a successful apache server running on port 80, however I want to create a virtual host on port 81. When I try I go to servers->Apache Webserver-> Create Virtual Host I change the port to 81 and the document root to /var/port81www then I click create. How ever when I goto 192.168.1.5:81 (local ip, I know I have to port forward but its not even working local) it does not work.

I am at my own desktop and I have root access on my own desktop.
I also have root access on a Desktop Ubuntu system (192.168.5.10) on the LAN. I need to create another desktop user account on that 192.168.5.10 system.
So I logged into that system with: ssh -Y myself@192.168.5.10
Then I did: sudo users-admin
This brings up the Users Settings but the Add User and Unlock buttons are disabled. How do I enable these buttons?

I am trying to use puttygen to create a ppk file that I can use with putty. I try to import the private key and it gives me the error: Couldn't load private key (ciphers other than DES-EDE3-CBC not supported). Now I obviously know this is telling me that I have the wrong cipher, but what what do I do to use the correct one? Here are the instructions that I used to create the keys.
Also, when I open the key this is the top:
- BEGIN RSA PRIVATE KEY -
Proc-Type: 4,ENCRYPTED
DEK-Info: AES-128-CBC
and then some other stuff that I don't think I should share. But the weird thing (to me atleast) is that it lists CBC right at the top there which is what puttygen wants. Why won't it accept it?

I am looking at creating two user accounts for "contract system admins"..These guys will be performing sys admin duties for a sever -- however, I am still concerned about security of data. For example, the server contains password information for our database, etc.Besides making them sign an NDA, etc. what other security mechanisms could I put in place to ensure that they don't just go buck wild. For example, when someone makes a sudo command, is this logged?
what are some recommendations for general security practices?

I am working to create a new base image for our RHEL5 setups, and I wanted to make sure we are creating a functional, but secure, image. Can anyone point me to some writeup's that might provide some illumination on this potentially daunting task? Basically, I'm concerned about what packages are okay, which should be avoided, and what other caveats that I might not think of when putting this together.

I'm trying to set up a firewall at the moment that allows access to my custom SSH port from only my friend's url (they have a static url but dynamic IP). I find iptables a bit of a nightmare and was hoping to use UFW for most of my day to day firewall maintenance and just make a few extra iptable rules to cover exceptional circumstances like this. Fortunately it seems UFW allows this with /etc/ufw/before.rules and /etc/ufw/after.rules. So at the moment I'm just trying to get the basic iptables rules right. As I say I'm not very good with iptables, does this look right?
Code:
## Drop Default SSH port access With Logging
iptables -N SSH_DEFAULT
iptables -A INPUT -p tcp --dport 22 -m state --state NEW -j SSH_DEFAULT
[code].....

Installed 10.04 as a LAMP. I want to be able to create a new intranet site for testing purposes.
When creating a new site with in apache, what is the recommendation for the folder? With in the var/www? Everything appears to want a domain address and since its local only, what do I use as a domain?
I have webmin installed and I would think creating a virutual server would be my first step, but I am getting hung up on the domain address.

jump into a Linux class in college with only 3 weeks left in the course. I thought I would be able to catch on, and go figure, it didn't exactly happen that way. I was given an assignment to do, and I am so far lost it isn't even funny. I need to create a directory structure, set up file security, create a step by step instruction manual on how to copy/delete said files, and create a guide to common Linux commands. How would I create these files in root and share them with the other users? and where can I find a list of common commands and their functions?

I'm trying to use a technique suggested by a fella at this website....
[URL]
He suggests adding an echo line to the actionban line in order to create or add to a file that will contain a list of all the IP's that fail2ban has banned.....but it doesn't seem to generate any output. .....here is the command.....
actionban = iptables -I fail2ban- 1 -s -j DROP
echo >> /etc/shitlist
I never get any IP's in the file so the echo part does not seem to work.

What is the recommended filesystem to use when creating a home server/nas?
I'd be sharing files using SAMBA, DLNA Server or some sort of streaming. I'll have two win7 laptops, 2 ubuntu desktops and ps3 accessing the files. Most of the time the server will just 75% read from 25% writing.
Would ext4 be an ideal?

I need to create .conf and .load files for php. PHP is installed and I've verified PHP with
test.php <?php
print_r (phpinfo());

Is there boilerplate available for creating the .load and .conf files? I am having trouble finding it in what's been installed.

I have a little problem: I have a share folder on Ubuntu server: - Dump That folder is share with SAMBA and everyone can put files on it
My problem is the following: When someone create a folder, the folder permissions are automatically set with:
(let's take my username: Yann)
Owner: Yann
Group: Yann
Clearly that's wrong.. I want the Group to be auto set has "users" so everyone can access the folders on that share. Anyone know how to change this ? chmod and chown is getting a bit boring

I am thinking of starting a business creating web pages and supplying a 'enterprise server' type solutions, whilst still being highly cost effective - eg recomend the client to use an 'old' pc for the majority of their server needs (LDAP, mail, firewall, web server etc). I plan on doing all of this on a linux platform, so as to pass the cost savings of related 'microsoft enterprise systems' to my clients ~ thereby making my proposition more interesting to clients. However I'm not sure if the 'old' pc idea will 'cut the mustard' in terms of serving web pages. So my real question is, at what point does the speed of the internet connection reach a bottle neck with the speed of my CPU? As an 'example' in case I'm not being very clear (which I'm not sure I am).
My old pc has an AMD athlon chip in it, and equally old 30GB and 40GB HDD (SCSI ~ did I mention that they are old!). My intention is to set up a system to the above type specification at home, to see how long it takes me to do, and to give me an idea of what I should charge clients. I understand all the technology, but initially (to save on personal startup costs) I was intending to use my old pc as my personal gateway to the world, $40 for the web registration for 1 year is a considerable saving compared to the $20 per month for a hosted service ~ although as soon as things are going and being 'profitable' I would most likely either upgrade my server or get a hosted service. Any tools I can download onto the server to 'determine' the power consumption over any given period?

I have an Ubuntu server running Samba and I would like to share out the cdrom drive to the network. I made a share of the /media directory and it seems to work fine when I insert USB drives and I am able to browse and work with files. However, when I insert a cdrom it automatically mounts to /media/<volume name> and I get a permission denied error when I attempt to access it over the network. I am assuming this is happening because the permissions do not include the execute bit and being a read only file system I can not change this. I made the directory /media/cdrom and manually mounted the cdrom to it and I can successfully access it over the network just like the USB drives. So my question is: Is there a way to make the cdrom automatically mount and unmount to /media/cdrom when I insert and eject disks instead of to /media/<volume name>? Or maybe just have the permissions automatically set so Samba users can open it instead of just see it.

I am looking into creating a web caching server for myself using fedora 10. I believe I need to use squid for this but it seems to have a lot of features. Basically, all I want for now is to be able to cache web pages that I and my network users use the most, increasing access time and lowering the load on my internet connection. Can squid do this and can someone point in the right direction on an article on how to configure such a thing?

I'm putting a server together and have run into a boot up problem. (I thought about putting this in the server forum, but it might be a more generic problem that others have seen and know how to rectify.) The install seems to have gone just fine. I have the /boot partition on an internal IDE drive. The rest of that drive and another are mirrored in a Raid0 configuration (using the Linux software to do that) for data storage. The swap partition is a part of the Raid5 SCSI array that also has the / (root) partition on it.
After installation it would not finish the booting process. I suspected that GRUB didn't like all the Raid arrays and such, but it seems to be fine. I can say that because the machine will boot into rescue mode with the GUI splash screen and I have access to the whole directory tree. I have already searched on-line and following prudent advice, ran the yum update while in the chroot /mnt/sysimage mode. That only took overnight to download and most of this morning to complete. Still no dice. Used vim to delete the rhgb quiet commands in the grub.conf file so I could see where the kernel seems to be hanging.
So right after the "Creating initial device nodes" is a line about my generic PS2 wheel mouse. So I tried a USB mouse. Got more output so tried swapping out to a USB keyboard. Got a little further with more information about input devices, but still stops. Also, I tried a PCI video card just to make sure the onboard video wasn't the problem - no change. So, if someone in the Fedora community knows what loads up or is configured right after the mouse and keyboard, I might be able to figure out what's causing the computer to hang during the boot process.

I'm working on setting up a new subversion server and getting an error I'm not having much luck resolving.
I'm attempting to create the repository in /home/svn/foo with the command svnadmin create /home/svn/foo while in /home/svn.
I am greeted with the error: svnadmin: SQLite compiled for 3.6.20, but running with 3.6.17
I installed subversion via yum install subversion
I've installed SQLite 3.6.22 from source and removed/installed subversion with no change.
What gives? I wasn't really wanting to install subversion from source. Seems a bit excessive.
Environment stuff:
[root@COS svn]# yum repolist
Loaded plugins: presto, refresh-packagekit
repo id repo name status
fedora Fedora 12 - i386 enabled: 15,366
updates Fedora 12 - i386 - Updates enabled: 4,731
