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.

Networking :: Bandwidth Monitoring - Each Person Usage?

May 8, 2009

I have a server rack that I lease out to others. I need a way to monitor each persons bandwidth usage. How can I do this without installing software on their machines or disrupting traffic flow? I have no access to the router, as it is owned by the colo company. I do have access to the switch and firewall, as well as my machines (linux) on the rack.

Networking :: Limiting Bandwidth Per IP In Ubuntu

Apr 12, 2010

You may have seen some other posts by me about my final year college project. Im implementing a web based network management website. Iv got a lot of the functionality working at this stage but one part is allocating bandwidth.

Iv got an eircom 3mb broadband connection and I want to be able to split this between users. At the moment I only have my desktop and laptop on the network. Im looking for advice on how i can allocate bandwidth with iptables and/or the tc tool in ubuntu.

My website is on an ubuntu virtual machine and written in php. Whatever about running the iptables and tc commands from php I still need to figure out the actual commands i need to use in the first place.

Server :: Limiting A Sub-user's Bandwidth?

Jan 27, 2011

I run Debian 64-bit. I host GameServers on my machine. Yesterday, some corrupt files or error in configurations of one of the game-servers caused my whole system to destabilize. On checking, I saw one of the Gameserver's console giving Net_sendpacket spam errors. I disabled that server and things were fine then. It used up more than 100GB of my bandwidth in just 12 hours.

I deleted the server and copied all the files over again to fix that error. Now I want a prevention to this, if just in case it happens again. I want to limit a sub-user's bandwidth in Linux. Like if I want a user only to use 10GB bandwidth per month + not more than 5MB/second. Is there any way to do it?

Fedora Networking :: Finding The Upcoming Bandwidth And Specify The Bandwidth Rateto Classes

Nov 18, 2010

I created a the class like this for shaping the packets with a specified bandwidth rate.....

tc qdisc del dev eth0 root
tc qdisc add dev eth0 root handle 1: htb default 15
tc class add dev eth0 parent 1:0 classid 1:1 htb rate 750kbit ceil 750kbit
tc class add dev eth0 parent 1:1 classid 1:3 htb rate 600kbit ceil 750kbit prio 0

For Our Requirement:-

I dont want to specify the bandwidth rate strictly like this rate750kbit ceil 750kbit,based on whatever speed is coming which should allocate the bandwidth rate for particular class...I need one application for finding the upcoming bandwidth & Is any other method is there for specify the bandwidth rate in a classes.

Software :: Backup Size Limiting - BackInTime Doesn't Have An Option To Limit Disk Space Used

Oct 15, 2010

I have BackInTime backing up my computer to a RAID cluster. The problem is that BackInTime doesn't have an option to limit disk space used. I also use this drive as a fileserver, and need to be able to keep some space open for that.

Is there a way that I can limit the amount of space a specific folder can take up? Alternately, is it possible to create a disk image that will only take up the amount of space in the image, but can automatically expand to a certain size? It would work similar to the Mac SpaseBundle format.

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.

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 :: Realtime Bandwidth Monitor 10.10 (Bridged Connection)

Apr 14, 2011

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.

Fedora Security :: Limiting Sudo - Giving Full Privileges To The Wheel Group In The Sudoers File

Feb 15, 2011

I have previously set up sudo via adding my name to the wheel group and then giving full privileges to the wheel group in the sudoers file. Now I choose to learn to limit that. Had noticed the most frequent use I have of sudo is to run yum update. This got me thinking, could I remove the wheel group privileges and add the following line in sudoers to limit the privilege to simply running yum, and furthermore, make it so I could run yum without a password:

## Allow root to run any commands anywhere
Troy ALL= NOPASSWD: /usr/bin/yum

I think that would in fact work (if I understood one of the pages here, it will work). However, upon further thinking I realized that in such a case then anyone sitting at my computer could then use yum, without a password, to install or remove any file on my system � probably not a good idea. As a result I have to ask, can I tighten the privilege even further such that the only privilege so given was to run �yum update� and nothing else? (for example if they ran �yum install� it would fail). If you can do it, how?

Last, I was going to limit the privilege, time wise and try wise, by adding the following to the sudoers file:

# Defaults specification
Defaults:Troy timestamp_timeout=0, passwd_tries=3

Will that really work to limit the elevated privilege so I don't have elevated privileges lingering about, or is there a better way to do so?

Fedora Servers :: Apache Doesn't Resolve Hosts?

Nov 2, 2009

Recently my home PC crashed and I had to re-installed it. I put a "clean" install of Fedora11, then copied my /home directory and some other stuff over from the old installation.I have a couple of PHP scripts I wrote, and one of them stopped working. It uses cURL, and when I enable error tracking I get:cURL error number:6cURL errorouldn't resolve host 'www.host.com'I started digging around and I found out Apache doesn't resolve anything at all, so it's not only a cURL problem. For example,

$ip = gethostbyname('host.com');
echo $ip; die();

returns "host.com" and not an IP address.My best guess so far is that Apache has no access to the DNS service (from command line and in browsers everything resolves). had a suspicion it's a SElinux issue and disabled it, but that didn't change anything.I found some old forum posts mentioning problems with chroot-ed Apache, but I haven't done anything to mine and in any case couldn't figure out what the problem was, or the solution, so I'm stuck.

Fedora Servers :: Sshd Within Xinetd Doesn't Work

Aug 21, 2010

I recently installed Fedora 13 on VMware 7 environment without X window. sshd did work fine, but when I tried to put it into xinetd, it doesn't work any more. Here is what I have done so far :

I stopped sshd. #service sshd stop

and I configured xinetd.conf like below.


# This is the master xinetd configuration file. Settings in the
# default section will be inherited by all service configurations
# unless explicitly overridden in the service configuration. See
# xinetd.conf in the man pages for a more detailed explanation of
# these attributes.


I don't know what I did wrong with them. I configured xinetd.conf, and I made service configuration file 'ssh' in /etc/xinetd.d, and I restarted xinetd.

What am I supposed to do to make a life on my sshd within xinetd ?

Fedora Servers :: DYNDNS Changed Public Key - Now Scp Doesn't Work

Apr 9, 2010

A week ago or so neither ssh nor scp were working when attempting to connect to my on-campus computer from home. ssh was complainig about the key not matching and I figured out I could just delete the config file it was reading the (now old) key from and let it create a new one with the updated key upon prompting me whether or not to trust the remote host.

However, even though ssh is now working, I can no longer use scp. I issued scp -v and discovered a bunch of errors. scp prompts me for the remote password and even prints the message of the day on the remote computer but then just hangs and doesn't seem to be copying any files. I'm sure the issue is with the whole key change issue but I can't quite figure out why ssh would be working just fine and scp would be failing.
