Ubuntu Servers :: Best Way To Manage Bandwidth On A LAN?

Oct 28, 2010

I'm looking for an effective way to manage use of internet bandwidth by users on a local area network. Currently there is a simple broadband router and unmanaged switch, and a standalone Ubuntu Server (8.04) that provides DHCP, DNS and mail for the LAN, and a web server. Ports are forwarded from a static external IP address to HTTP, HTTPS, SMTP, SSH and IMAPS, and some security is provided by IP Tables (managed by using UFW).

There are 5 users on the network, and currently one or two of those 5 are using beyond our monthly download allowance of 30Gb. 1) To be aware of how many users are currently using the internet connection, and to divide the bandwidth between that number (so that if there are, say, 3 active connections, the total bandwidth available is divided 3 ways, rather than one of those users being able to hog all of it).

2) To allow each user to download up to 1/5 of 30Gb each month without any additional throttling (apart from the above), but once they go over that allowance to throttle them individually to, say, 10Kbps until the start of the new month.

I've heard other threads talking about both IP Tables and a proxy server such as Squid. I have no idea which of these would be most suited to the task. Currently, as I said, the Ubuntu server is standalone and only using 1 NIC, but it has 2 NICs and I could be configured to act as a gateway for the LAN, instead of the router, which is set to be the current default gateway.

Apr 30, 2010

I setup a server with vmware esxi 4. I installed opensuse 11.2 and I have successfully setup an internet gateway and I manually configured (static) my client IP. My question is, is there any software or commands that I could use to manage the bandwidth usage for each client? eg. only 5Mbps for 192.168.1.5, 10Mbps for 192.168.1.10, etc

Ubuntu Servers :: LAMP - How To Manage Permissions

Jan 13, 2010

I have a LAMP server running Ubuntu 8.04.03 Server edition running smoothly. Ive setup several websites on the server and all are ok, but I constantly have trouble with permissions. Everytime I setup a new domain to host, I setup a user specific to that domain. This allows SSH login specific to the domain. The problem I have is that every time I setup ownership in the virtual directories for the users they belong to, the settings don't seem to stay. Initially it seems to work ok, but when I install Joomla and setup the webspace, I always seem to have to login to the server itself to chmod the folders I need to have writable. I cant chmod properly from my FTP client which is weird. How to manage permissions?

Currently I am doing the following:
Code:
sudo mkdir -p {name of domain}/{public,private, etc...}
sudo usermod -g www-data {my user name}
sudo chown -R www-data:www-data /var/www/{directory for the domain}
sudo chmod -R 775 {folder path I need to change}

This works for a while but as I add new things to Joomla and I want to modify the folders, I always have to go back and redo the chmod and the chown commands to get them where I want.

Ubuntu Servers :: Setting Up Server To Manage Network?

Mar 31, 2010

I have a server on my home network. It's currently running a DNS server (bind9) and an HTTP caching server (squid).What I would like to do is redirect all outgoing port 80 connections to the squid server and also make the server responsible for managing DHCP on the network.

Do I just need to install a DHCP daemon on the server, disable it on the router, then set my server as the default gateway and configure iptables to route all connections like I want? Or is it more complicated than that? Also, would that mean that all communication between two computers on the network will go through the server?

Ubuntu Servers :: Server Application To Manage Staff Skills

Nov 17, 2010

We are looking for a web based, server application to manage staff skills running on ubuntu (10.04 lts). Something like we attach tags with skills to people photographs, and then when people connect to the application by means of a browser, they see a list of tags, they click on a tag they get a list of people who have that skill. Ideally, the tags should be hierarchical (for example, skill: statistics, subskill: non-linear).

Ubuntu Servers :: Enable DNS To Manage Subdomains On Main Host?

Feb 12, 2011

I have a server with multiple domains and a DNS service (bind9) my main domain is registered with GoDaddy and it's A-record points to my server, it then has CNAME records with ns1 and ns2. I use ns1 and ns2 to point my other domains to the DNS server I host, which then manages what happens.

Anyway, what I would like to do is enable the DNS server to manage the subdomains on my main host. For example, if the domain was example.com and I use admin.example.com in the DNS server, it will not follow through unless I set the cname up, whereas my others will. How do I do a similar thing for my main domain.

Ubuntu Servers :: How To Switch Off Bandwidth Monitoring

Ubuntu Servers :: Bandwidth Aggregation Software Per Ip?

May 19, 2010

I am running Ubuntu server 9.10 and I am trying to find a way to cumulate and visualized bandwidth for all the ips on my network.

I created a server connected to a mirror port of my router and I am running snort and nessus and ntop to monitor and scan my network for security. Everything is running fine and I can see all the traffic happening, ntop creates really nice report of what is going on in the network, snort with base alert me of probable security problem and nessus help me secure the network with weekly scans.

What else do I need ? I really simply need a software that will calculate the total bandwith usage per ip address. Ntop seems to gather all that information somewhere, but there is not simple way to get the information out of it. I was thinking maybe cacti would be the software to use but I am not too familiar with Cacti and it's interface seems a bit daunting still.

I don't need it to be web interface - but it would be nice. I could probably rig up something on a console base program. What I want the output to be should look like tcptrack but with the running totals for last day, last month, last year, and if there could be a graph for it- even better.

Ubuntu Servers :: Share Bandwidth Over Internet?

Sep 6, 2010

Is it possible to share bandwidth over Internet? A friend of me has made a little radio station with win-amp to screw around with. But as you can guess after 10 users the connection flips due to bandwidth limits. So we where wondering if we somehow can share both our bandwidth. I was thinking about perhaps linking some proxy's and combine that with load balancing... Something like that! But i'm not even sure if it's possible to do so.

Ubuntu Servers :: Prompt Root Password When Attempt To Manage Users And Groups Through The GUI

Mar 20, 2010

So i have a fresh install of the server edition of Karmic, i'm running the Xfce desktop. When I attempt to manage users and groups through the GUI, I am prompted for what I think is the root password, the reason I say this is because the account I am currently logged in has sudo privileges and it does not accept that password at all, but I read that by default the root account is 'locked,' (to be honest it was so long ago since I last installed Ubuntu I completely forgot if it is or isn't, my current desktop installation has su access) is it asking for the root password? why doesn't my current user account password work if the root account is 'locked'? I can perform all other administrative tasks with sudo no problem.

the funny thing is, I have the exact same setup in a virtual machine, the same problem happens, except for some strange reason after changing the password on the only account (besides root), the password required to administer users and groups stayed the same after the change. (at the time of installation I just put both the user and root password the same and now that it is setup), i'm now ready to change the passwords. except now I read that the root account is locked by default, but this strange problem occurs.

Ubuntu Servers :: Remote Desktop To Manage File Downloads From Windows 7 Machine(s) Big List?

Feb 17, 2010

I've got an old p3 with 11 ide hard drives strapped to it for storage and I decided to throw Ubuntu server on it because it's more lightweight than a standard ubuntu install, and given it's a pentium 3 with 128mb of ram, lightweight is good. I installed, through putty (ssh), the gnome gui - then learned that putty only does cli (i was thrilled), so I've spend the last hour trying to figure out how to enable remote desktop.

I don't mind reinstalling to do what is necessary. remote desktop to manage file downloads from my windows 7 machine(s) big list, i know. history: this thing is/was my media server. I had xp on it, sharing all drives and watching hd movies off it, but then xp decided it did't want to boot anymore so here we are. I'm thinking of just putting ubuntu 8.04/8.10 on it and through its wonderful gui enabling remote desktop and using realvnc/tightvnc to access it

Ubuntu Servers :: Realtime Bandwidth Monitor 10.10 (Bridged Connection)

I posted this in the Networking section, but should probably be over here. Couldn't move it. I have a transparent proxy in place. I have Webmin installed on the server. Is there an app that can monitor bandwidth in real time? Also run reports? I have SARG installed, but seems to only monitor HTTP traffic, I need to monitor all traffic. I have a bridged connection, but monitoring the outside interface is fine too.

Ubuntu Servers :: Firestarter And Webmin Bandwidth Monitor Not Logging Anything When FS Is Active

Jan 7, 2010

I'm installing a server to act as a firewall between a local network and internet. I've installed Firestarter becaused it worked straitgh away (it seems that FS is configuring the routing as well). I've tried to remove it, and then I lost the access from LAN to Internet. (I don't know why -perhaps the routing is disabled then- , so I prefer to keep it).

The problem is that Webmin Bandwidth Monitor (bandwidthd) is not logging anything when FS is active. Does someone has an idea on how I could make it work? I've tried cacti and some other stuff, but it is far too complicated for me.

Ubuntu Servers :: Skews Bandwidth Usage When Pull Music Off The Server

I'm looking for a way to exclude all traffic on the local network and only count internet traffic. This is the filtering part of the config file

Fedora Servers :: Limiting - One Person Doesn't Use All The Bandwidth?

Jan 22, 2009

I have a fedora 9 server. It is used purely as a dedicated server. Until recently I never came close to my allowed bandwidth of 1 TB but I expect that may change in the near future because I will be adding many files for downloading. I have Apache 2.2.9, PHP 5.2.6, mySQL 5.0.51 and Webmin 1.441.

The most critical thing is monitoring total bandwidth and then doing a job, probably using Cron to change a folder's name, to stop downloads before a critical point is reached and my sites shut down. I would also probably eventually like to limit member downloads so all members of the sites get a chance to download and one person doesn't use all the bandwidth. I expect that would be possible using php. to log the bandwidth used by members. I know php but I don't know how to get the bandwidth using php.

Ubuntu :: Add An Application To Manage A Subtype?

Jul 7, 2010

I will try to explain. My bank send to me a file which has extension .fm6, but which is, in reality, a zipped file. I have a program, which runs more or less well under wine, to open them.

Now the problem is: how can I associate this kind of files to the application? I mean, I can change the application for *all* compressed zip files, I know how to do it, but I do not want it. Just zip files that happens to have a name ending in .fm6 should be associated with them.

I know it's possible. In the end, openoffice.org files are really zip files (try it), and they are treated differently.
