We're about to upgrade our Ubuntu server and are looking for a complete package set that includes a firewall, some kind of snoopy, and whatever else we "must have" or that would just be extremely useful. What do you guys find the most absolutely necessary and needed packages for running a linux server in regards to security and performance.

I have a server setup with all my web development stuff in /var/www and in several sub-folders within that. (each project having it's own folder)It works great with one FTP account. But recently I've been getting help on a projects from a buddy of mine that freelances, and have made him an FTP user account as well. All is fine, except for when he tries to edit a file and gets a permissions error.
Here's the issue, I don't want us to have the same FTP login, but all the files are currently owned by my user name. So, when he logs in to edit a file, he can't because I'm the owner, and the files are set to 744. Will I cause any harm by adding both users to the same group (www-data) and chmod'ing the files to 775 so that we can both access and modify the files?
I decided to create a file server for my family. I have set up a RAID 6 (4 disk) array. My thoughts were to back up the array to a hard drive monthly. Store the drive in a WiebeTech Drivebox, off site, in a "fire proof" box. (The kind for papers sold at Staples or Office Depot. After a year, I would have 12 back-ups. I would then overwrite the previous hard drive. (i.e. HDD from March 2011 would be overwritten on March 2012.)
Additionally, I was wondering if there was recommended maintenance to verify the array is working properly. Right now, I am moving data to the array so quickly that I am backing up every few days between three hard drives. (Back-up #4 was written to Drive #1 after Drive #1 was reformatted.) I am aware that I could use rsync. (Which I currently use for backing up my portable USB HDD to the RAID array.)
I am building an email server in what I consider to be a 'small business'. I would say my Postfix mail server will house 300 mailboxes (Max). I have a decent server with enough RAM / disk space to run this email server however I don't know what the best way is to manage / configure the users mail boxes.
how to create a new user on the Linux server using 'adduser / useradd' and then setting their shell to /bin/nologin. This is because the mail user will never need to log into the shell of the mail server directly and can still populate email from their mailbox which is located in their /home/$user directory. Now many people I spoke with have advised me that this is a bad and cumbersome method of account administration.
I am running:
Postfix 2.5
Clamav v0.94.2
Amavisd-new 2.5.4
Dovecot 1.0.7
Spamassassin 3.2.5
I want to build a NAS like mini pc to be used as a simple tomcat server (for running Jira and perhaps experimenting a bit) and as a GIT server. What kind of system requirements would I have?
Would something like this:[URL]../nas/n...sed-nas-part-2 be sufficient? And if I'd virtualized everything via VMWares would that make a lot of difference?
I am a total noob in the process of trying to build my own server. I installed Ubuntu 10.10 but when I did that I didn't have the computer hooked up with an ethernet or have any internet connection. During the installation process it was unable to set up DHCP, so I figured I would just do that later, somehow.
Anyways, I recently hooked up an ethernet cable from the server to another computer, which has internet.
I've been slowly working my way through the Server Documentation and am on the Networking chapter. It has given me the commands to install wireless-tools, ethtool, dhcp3 server and I've also tried to install gedit. Every time it gives me the error: E: Unable to locate package XXX
When I ran the sudo lshw -class network command I find that it recognizes both an ethernet interface as well as a wireless interface(my wireless adapter). BOTH of them say *-network DISABLED.
My goal is to enable both of those, but I am assuming I need to be able to locate the packages first. I installed the server edition using a USB pendrive. I still have the files on the pendrive, but I don't know how to make the server locate those files. I'm guessing it wants to access the installation files to locate the packages to install.
I think this is the right place to ask my question so I'll just go ahead. Where I live we have frequent power anomalies such as outage and why I would describe as power resets resulting in power being cut and restored in a very fast delay, resulting in all electrical equipment in my house to reset and all computers to improperly shutdown and reboot. I don't know how many times my beloved Linux server was reset like this and every time reiser fs has to replay transactions and so far I've been lucky I did not lose any hdd or other components but I think this will happen sooner than later.
What I am searching for is a device that would protect my server, scanner, router and a few other small devices from power surges and anomalies that would result in hardware and equipment damage. What I also want from that device is the capability to continue powering the devices until they properly shutdown. I think a ups is what I am looking for but all models that I've seen are priced $400 up and that's over my budget.
What I also want is the capability to announce to the server that the device is running on batteries and that the server can initiate it's normal shutdown procedure.
I am managing a PBX which runs redhat enterprise linux. The time on it is always getting out of sync, which causes the time on the phones to display incorrectly. I can't figure out for the life of me why the time keeps changing. How can I set it to update it's time every day or two? I don't want to hit ntp.org every day, as is recommended. What's the recommended interval for connecting to the ntp pool? The kernel is Linux 2.6.9-67.0.4 (from uname -a)
View 1 Replies View RelatedI don't want to screw up my system, but I need newer versions of packages then the ones in the apt repos. What is the community consensus on the best way to mix apt package management with building bleeding edge packages from source?
Should I build the source into a package and install it with apt? Should I avoid make install?
I would also like to be able to use multiple versions of the same package, and have some sort of sym link or something to determine which version gets executed.
I'm trying to turn an old Acer Aspire One with a tiny 8GB solid-state drive into a lean web server, so I'd like to remove as many packages as possible to free up space. It will be running a standard LAMP install and nothing else. Right now it has Ubuntu Netbook installed, so I need to know everything I can delete and still have it boot and run mysql, apache, etc.
View 5 Replies View RelatedI recently upgraded to 10.04 (clean install) and when I run apt-get upgrade, I get:
Code:
The following packages have been kept back: linux-headers-server linux-image-server linux-server
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded. why these updates have been held back?
I have created my first linux server using Ubuntu 10.04 server edition. My only experience with linux has been the desktop edition.
The initial trouble I'm having is that this server is on an isolated network without Internet access. I'd like to use a Gnome desktop like I'm used to in order to get up to speed quickly.
How do I get additional packages for a system that is not on the Internet? The end goal for this machine is a simple file depository for a W98 network using Samba shares. To boot from an IDE drive and share a 5 drive software RAID5 for data storage.
Code:
PHP Deprecated: Comments starting with '#' are deprecated in /etc/php5/apache2/conf.d/mcrypt.ini on line 1 in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib

I have checked for directories and the file it is looking for does not seem to exist. the only file in that folder is pdo.so
I'm currently writing a script that will update the software packages on six ubuntu servers so I don't have to go in and update them manually constantly. Problem is, I'm not sure which command I should use to do this the most effective and safe way. Currently, I use sudo apt-get upgrade -y on my own machine, though I can see how this could be dangerous on production servers. I was in the IRC chat and I was told aptitude safe-upgrade is something I may want to look into. Is there a way I can only update security related stuff instead of everything? What do you guys suggest would be the best way going about this? Another issue I can foresee is certain packages that have an interactive prompt. While apt-get upgrade -y takes care of most of this, MySQL would fail with this as it opens up it's own prompt. Anyway I could make my script skip these types of prompts, so I can go back and update them later manually?
View 1 Replies View RelatedSeems like always if I add a package with apt-get, next time I use aptitude to update packages on a server, the packages I added with apt-get are automatically marked for removal.
I must, in aptitude, "forget new packages" and "cancel pending actions" then update the package list, remark packages needing updating, THEN aptitude has forgotten it wanted to remove packages.
Why can aptitude and apt-get NOT get along!?
Currently I have 10.04 on all servers, thus where it still is a problem.
I've been running an overnight cron job for months on my servers which tells me what apt-get dist-upgrade wants to do.
This morning I was faced with it wanting to install 115 new packages including many (if not all - I can't face checking, e.g. firefox) which are entirely pointless on a server with no gui.
apt-get upgrade wants to do the sensible (in my mind) thing.
To save anyone asking, I've been using dist-upgrade because upgrade wouldn't report on pending kernel upgrades and, until I spotted that, I was due kernel upgrades for quite a while before I realised.
I presume this is caused by an over-enthusiastic depends or recommends somewhere but does anyone actually know?
Off to work now but I'll look further this evening so any pointers before then gratefully received.
All ok again now, the bug with language pack dependencies has been fixed - [URL]

View 5 Replies View RelatedI upgraded my dedicated server using the do-release-upgrade command, and it seems to have installed many extra packages I do not require.

So I'm getting a new laptop soon, and it ships with Windows 7 64-bit. So I assume I have to use 10.04 64-bit. I noticed that the download page says "not recommended for daily use". I was wondering why this is, and if there were any things I need to look out for when using Ubuntu and 64-bit. I read the older FAQ thread in the closed 64-bit forum, but I wanted to make sure I got more recent information.
View 5 Replies View RelatedI've been having some issues with the speed of firefox recently (on a netbook) and have been trying out other browsers such as chrome and midori. Currently I'm using xmarks, which fits my needs nicely however, I'm looking for an alternative that gives similar functionality and would allow me to access my bookmarks from several different computers (using both midori and chrome browsers).
xmarks has a development version for chrome, which is not working at the moment, and I cannot find any plans for xmarks in midori.

View 8 Replies View RelatedI have Ubuntu 10.10 but I can only use Windows 7 now (I hate it). Here's why: when I go to the boot screen and I am given the choice of using Windows 7 or Ubuntu and I select Ubuntu, the screen goes black and says:
error: unknown command 'loadfont' error: file not found
Then I have to reset my laptop and use Windows 7. This happened when I was using Ubuntu like I usually did and I downloaded recommended updates from Ubuntu. I downloaded them and I was asked to reset my laptop for it to be effective. I did and when the boot screen came up it said what it says above. I can't even get to the login screen. I've been searching everywhere for an answer.
I'm using 10.10. The FSpot and Shotwell programs that came with 10.10 don't seem to have any good controls for adjusting slide show display of photos. Could anyone recommend a good photo slide show display program that allows one to adjust pan, display time, smooth transitions, etc.
