I want to put a bandwidth limit on the 8000 port. The limit not have to be global! It must be per connection! For example if i put a 20kB/s limit on the 8000 port and I have 3 clients connected to the port, i want that each have the 20kB/s. How can I do that? I readed something about TC, but i don`t know how to use it... I`m a little noobie Sorry for my bad english

I want to use the tc rules for bandwidth control in my lan.i have a linux router(traffic shaper).how i can limit the amount of bandwidth every user has access to per day? For example, any user can't download more than 2 gb per day(or per month).
The information about lan's users(such as a group type,userid,etc.but not any thing about time limiting per user)is in ldap directory on ldap server.the linux server uses ldap server for authentication users when the user login.
I Own a netcafe and I want to limit the netspeed for some of the users on the network because some of them maybe use torrent or other ways to eat the bandwidth and the net became so slow for other users.
My task is a way to limit the net speed for some users on the network, I tried a mikrotik RouterOS but it look like a miss to install I wanted an easier way than this, I use linux or windows or any OS to make this task done please help me to do it !!
I want to limit bandwidth for downloading files with squid. I want to reserve bandwidth for other traffic (esp. web browsing). I know about delay pools but I don't understand well. Some users use download managers to download large movie files. I don't want to block downloading but I want to give them limited bandwidth. May be 5KBps or 6KBps because I have only 512Kbps (64KBps) connection.

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?
I need to adjust what exactly ufw LIMIT port# does.I like the fact that the port is getting limited, but ufw overdoes it a bit. Is there a config file somewhere I can edit?
View 5 Replies View RelatedI have a third party program (tightvnc) which I want to monitor and detect if it loses a connection with a client. I don't care if the client has the program open but isn't doing anything with it, I only want to know if the actual TCP connection is lost.
Since TCP takes forever to die on it's own I was thinking the best way to detect if a connection is lost is by bandwidth the bandwidth on the tcp port allocated to the VNC connection. Are there any tools built in to redhat (RHEL 5.2) which I could use to do this? Since I don't have full control of the operating system I would prefer to use built in tools rather then trying to get a new tool installed.
I've searched through the forums and found a few threads that kind of helped, but I'm still pretty lost when it comes to TC. I'm trying to do and also break it down and explain what each part of the command does so that I can learn along the way. What I'm trying to do is limit any connection from source port 6001 to 30KB/s.
I'm currently running a game server and it has no built in bandwidth limiting feature, which means if someone logs in and needs to download the map it destroys my bandwidth for the rest of the servers players. The game server is running on port 6001.
So I have a basic knowledge of Fedora, I have a LAMP stack on my box and I was wondering how to setup a router? My roomate is using too much bandwidth on his Nextflix, what's the best way to do this?

I recently read a windows tip which read: - Windows allots 20% of the bandwidth by default for various services like Windows update, spyware checks etc. We can get hold of this bandwith by changing the values of limit reserve bandwidth under QOS packet scheduler. Now my questions: How to limit the bandwidth usage used by ubuntu updates in the above lines?

View 1 Replies View RelatedIn my household a number of people use the internet. Up to a maximum of 3 wired connections and 2 wireless connections at its peak, all connection through my D-LINK G604T router. The problem is, when one person is downloading or watching ..... or whatever, the others using the internet suffer. I've spent hours configuring QoS on my router, and long story short, no matter how I configure it, it just simply does not work. QoS in no way shape or form limits connection speed (which it says it should). Anyway.
I have a spare computer under my desk, and I'd like to know if I could set this up with a (free) linux distro that limits bandwidth speed per connection. For example, of the 1500 kb/ps (about) my modem pulls, is there a way to limit that to 768 or 512 per connection? so person A can still download, person B can still watch ....., and person C can still play counterstrike with a latency under 100. This would solve many, many arguments in my house I am *fairly* good with computers, but if the distro came with documentation and a GUI that would be awesome.
* TL;DR: *
Is there a linux distro I can load on a spare computer that limits bandwidth per connection, wireless or otherwise, with good documentation?
Failing that is there firmware I can use for my modem (dlink g604t) that would do the same?
Failing that do you know of any good hitmen that would solve my family arguments, ahem, permanently?

View 11 Replies View RelatedCan I, with only the use of IPTABLES, limit the incoming bandwith for a protocol? We have for example servers that have a FTP and HTTP server running and whenever HTTP has a lot of connections open, the other uploads/downloads get a timeout. I know I can limit the number of connections but prefer to limit on protocol level. Is this possible using IPTABLES and if so, can someone indicate how to proceed or provide a link? If it's not possible can someone point me to the right tool for the job?
View 6 Replies View RelatedI created a the class like this for shaping the packets with a specified bandwidth rate.....
tc qdisc del dev eth0 root

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 have an application written in C (by somebody else) monitoring a device connected to a serial port. I'm using an old laptop w. tinycore linux for an os. The app works well enough, and the communication speed is relatively slow, 9600bps, unidirectional, comes in packets of 18 bytes. The app is just picking apart the packets and displaying the contents on a formatted screen (ncurses), updating about once every 1/2 second. The trouble is, the app is polling the serial port and using *all* of the cpu bandwidth. The cpu fan runs full bore all the time.
Other activities are sluggish when the monitoring program is running. I'd like to modify the app to be a little more intelligent, use a receive buffer and interrupts to trigger processing each packet and, most importantly, not poll in a tight loop waiting for data. I'm not sure where to start, but I'm convinced this isn't that complicated of a change. Is there a good resource that would explain the basics of reading data from serial port software buffers, triggering on interrupts and suspending or sleeping when no interrupt is pending?
I am at a loss how to prevent Denial of Service attacks to port 25 and not block legitimate connections from 2 Barracuda 800(s) and block smart phones such as iPhones/Blackberrys/iPhones that use the server smtp.server.com for email.
Presently for port 25
RH-Firewall-1-INPUT -p tcp -m state --state NEW -m tcp --dport 25 -j ACCEPT
The 2 Barracuda 800(s) make port 25 connections all the time, plus users with smart_phones have the incoming server type:
IMAP
pop.server.com
smtp.server.com
Is there a way to keep Denial of Service attacks from happening with iptables rules without causing blocking to the Barracuda(s) that make constant port 25 connections & smart phones that poll? I was thinking if I allowed the Barracuda(s) in these lines
-s (barracuda)24.xx.xx.xx -d (emailserver)24.00.xx.xx -p tcp -m tcp --dport 25 -m state --state NEW -j ACCEPT
Where the source would be the Barracuda going to the email server. It would be allowed, then I am left with how to allow other connections like Smart_Phones that connect via Port 25. I am thinking if I put rules in place doing connection counts in a minute it would result in errors connecting to the server and people would start complaining. Plus any limiting may result in blocking real traffic. Then would I need to allow the ISP range in the above example to accept port 25, I am still left with how to drop a flood/denial of service attack.

View 1 Replies View RelatedI'm trying to limit access to port 8443 on our server to 2 specific IP addresses. For some reason, access is still being allowed even though I drop all packets that aren't from the named IP addresses. The default policy is ACCEPT on the INPUT chain and this is how we want to keep it for various reasons I wont get into here. Here's the output from iptables -vnL
[Code]...
Note the actual IP we are using is masked here with 123.123.123.123. Until I can get everything working properly, we're only allowing access from 1 IP instead of 2. We can add the other one once it all works right. I haven't worked with iptables very much. So I'm quite confused about why packets matching the DROP criteria are still being allowed.

I'm running Fedora 15, and am trying to run a program that uses gsoap/soapcpp2 2.7.17 to communicate with different parts of the program. As far as I know everything has compiled correctly and I am using the same versions of the required libraries as several working installations. However, every single time the program tries to open a port, the program is unable to do so. This happens no matter what port I specify.
if there is anything in fedora that would limit or disable the ability of the program to open a port to start communicating. I have tried disabling the firewall with no change to the behaviour.
I'm trying to make the changes listed in post #5 here to my Inspiron 8000: There's no xorg.conf in Xubuntu 10.04. But I figured out how to create one, and I edited it as suggested. But there's no menu.lst in Xubuntu 10.04 either. That is, the file called "menu.lst" is located in
/usr/share/doc/memtest86+/examples
and it has no "defoptions" line. So how can I make the poster's suggested changes (i.e., do something functionally equivalent, assuming that's possible) to my newer system?
