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?

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.

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.

recently i rent a xen vps intended to setup a PPTPD vpn server for me and my friends. so we can by-pass the great firewall in china and get back on ....., facebook and stuff. i have already setup the server and i can connect to it without any problem. but i still want to do some further configuration the server:
1. i want to limit the bandwidth to 400k/s per connection.
2. i also want to limit the max connection per user a/c
i have some thoughts on the 2nd requirement. in the user configuration file of /etc/ppp/chap-secret, you can specify the range of ip the user can get, does it limit the max connection per user a/c? or they can connect anyway, just every now and then a box pop up says conflict in IP address?

Is there anyway to monitor the current bandwidth in use by a user (NCSA auth) on squid? Occasionally we get a user downloading too many videos at once, which blocks bandwidth to other users on the network. As I have no idea which user it is until the end of the day (SARG reports), we just restart the squid server to disconnect their downloads.

I just created new user account, but the new user is able to access all the directories structure (including other's home directories).I'd like to limit the user to access ONLY his home directory (and nothing "above"). How do I do this?

I have 2 ISP where give me IP Public with ISP A (/29) and ISP B (/28). So, I connect this two ISP to unmanaged switch. And from that switch, I take one cable connected to eth0 on the server. (Note : My server have 2 dev ethernet, eth0 and eth1). eth1 will go to the Switch which will go to the LAN.
My Question is : 1. Is this possible to make bandwith control on the gateway server with mode separating International bandwith and local bandwith (my country bandwith)? ie, for my Mail Server I will give the "intl bandwith" only 512 kpbs and for local bandwith with 1Mbps. What a software can I use for this model ?
2. Which model I should to used, with NAT or with Bridging router? That's all for now..

I have about 5 machines that are under Ddos daily and I use rate-limit for Iptables to protect that and it works good.My UDP ports 20100 to 20400 are actually under Ddos so these are the commands I use:
Code:
A INPUT -p udp -m udp --dport 20100:20500 -m state --state NEW -m recent --set --name DEFAULT --rsource
[code]....

My server listens to POP3/IMAP requests. Some users have configured their mailers with high checking frequencies, say once every minute, such that the system logs are full of entries with no significance at all.I'd like to ask if there is a way to limit the per IP frequency of POP3/IMAP access ?I'm using "xinetd" to wrap the "ipop3d" and "imapd" which come with the Alpine package.

I have a Linux host connected via LAN to Internet. No proxy or squid is used on the host and outgoing traffic to Internet is not limited. I have several local users on this box. Recently bandwidth statistics on the switch/router showed increase in the Internet traffic from this host. How do I monitor the traffic utilization per local user on Linux host? I want to be able to monitor the amount of traffic per port and per user, like user alice downloaded 20GB today via port 22, and so on. Do not offer to use Squid, this is not just web traffic I want to monirot but all amount of incoming/outgoing traffic per user per port.

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.

I am looking to probably make a home server act as a backup for most of my data but also as a media server. I want to host all my music and videos for the most part on the server and then regardless what computer I'm using I could listen or watch. (Another question would be could I have itunes find my music on the server and play it).
But anyway, from people with home media servers, what kind of bandwidth usage do you go through a month? Comcast (ISP) limits me to 250GB and I'm thinking this is enough for moderate usage, I just want to make sure before I start the project.

how much bandwidth does the nxserver client use? Some places have reasonably priced mobile broadband but they limit the Gb usage. As I have a server with unlimited bandwidth, I though I could coonnect to it through nxserver and just use the server via the connection...

I'm getting DDoS attacks on my server, and I need to block all the attacking IPs.But for that I need to know which IPs are attacking me.I was thinking that I should log the bandwidth usage per IP so I can tell which IPs are using excessive bandwidth.How can I achieve this? I'm using Ubuntu 10.10.

when the server is getting overloaded with users. At present I run the server mainly as a proxy server with about 100 users. The bandwidth at the data centre is 100Mbps connection with total bandwidth used last month = 17431.16 MB
I would like to add a VPN in future but feel that this might overload the bandwidth as instead of it just being web traffic it will the entire client TCP connections. I would like to monitor this before it gets to the stage where users are complaining but not sure how to gauge whether the proxy is being overloaded. It is used mainly for video traffic.

I have a server in a data centre, which is supposed to have a 100Mbit line. Peak rates at the moment on my server are in the region of 20Mb, which should be easily handled. Is there anyway I can trace how much more bandwidth is available at any one time or if things are becoming sluggish on the server?

I want to rent a (root) linux server to run a vpn service on it. I want to allow people to use this vpn.
My questions are as follows:
- What kind of server/service should I rent - dedicated or vps?
- Is one IP-Address enough to connect, say, 100 user? (I plan to run IPsec or OpenVPN, maybe PPTP)
- What Bandwith and/or traffic limits I need to consider to make the service reasonably fast for the users?
- Which Linux-distro should I use? Ubuntu Server, CentOS, FreeBSD, Debian etc?
- How much RAM and HDD space is recommended for such an endevour?
- Any advice on the processor type the server should have?
- Is 100M network ok or better 1000M?
- What means 100Mbps shared bandwidth in contrast to 10Mbps dedicated guaranteed per server?

I wanted to implement a server for a small network, but am a bit in-experienced. The server that I want to use should be able to do load-balancing (two connections) and also act as firewall/proxy. And also it should be able to do some bandwidth management. The network that its going to serve has two parts. One part of the network should be served, say during day time,and the other during night time. The one that is going to be served at night-time should not have access to internet during day-time, but should have access to, say local mirror-server. I am a bit confused what software/hardware to use. I am planing to use EndianFirewall, but since I don't have experience, don't know if it can do all that I need (?).

I'm looking for a program that I can use to keep track of how much bandwidth goes to the various computers in my small network.All of the bandwidth goes through my squid server, so the easiest would be to just have a program that can accurately analyze the squid logs and tell me how much bandwidth is going to the different computers.I've tried both "bandwidthd" and "calamaris" I can't figure out how to get either one to actually do anything in Ubuntu.
