Can ubuntu be configured to reserve more bandwidth for some domains at the expense of others?
Eg you are browsing facebook and data comes faster than on a tab where you are browsing ......
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.
We have a sipmle office network set up that we also use use to connect to the internet, however of late the number of users has increased thus slowing internet access. Bandwidth upgrade is not an option thus i have to do bandwidth shaping on our linux router. The question is how do set the squid configs to allow certain IP's range a certain percentage bandwidtheg 60% and furthe divide the rest. Alternatively how can allow certain IPs to have higher bandwidth access.

I thought, perhaps from one and one, have public IP blocked, but the funny thing is that from another PC that I have at same room (with Ubuntu 10.04 too) connected to the same internet connection (with the same public IP Address) works perfectly. What else can I check?
I'll post an scenario and hopefully you can help me understand the concept and put me in the right track and do what I intend, if possible. Let's say I have a dedicated server with 2 static IPs each with an associated domain, let's call them www.site1.com and www.site2.com. Now, apache is running on it, I'd like to redirect anyone coming from site1.com to /home/site1/public_html and anyone coming from site2.com to /home/site2/public_html.In short, apache serving 2 entire roots depending on the accessed IP/domain. Whether the sites root are in the same parent folder, such as /home/site/site1_public_html and /home/site/site2_public_html or like above doesn't really matter, as long as it works.Additionally, do something similar with Postfix, so that I can have it running imap/smtp for foobar@site1.com and foobar@site2.com on the same server.At this moment, both apache and postfix are working, and we host only www.site1.com with the respective foobar@site1.com. But I'm not sure how to proceed or even if it's possible to achieve the above solution.

When I try to ssh into my account I have on a linux server where I keep some of my files (I'm using Cisco VPN) ssh claims it can't find the address.It's worked fine before, and if I connect using putty in Virtualbox on the same machine it works.The problem applies both to command line ssh and NetBeans (which uses a java client).I've tried setting SSH not to resolve DNS in the config file but it doesn't help.

But there I only could change the the domain for the entire system. Is it possbile to edit the Domain for each network interface. If yes how?

View 1 Replies View RelatedI have two virtual hosts that I want to be able to send through one router. I have two seperate dynamic hostnames on dyndns.
Apparently my router allows me to enter two seperate hostnames locally as well: DynDNS Host and Domain Name
Code:
How do I tell the router which is which? Currently I see the same site with both URLs
Do I have to set one vhost to do some 'funky' stuff (black hole in my head when it comes to static routes or BIND? ). And then set the other vhost to host both sites?
I'm running CentOS and an apache webserver. I want to demo a web site 'externally' from two different sub-domains.
I've looked high and low but most examples don't seem to be simply trying to put two different web-sites up to two Dynamic DNS Hosts.
It must be possible, all the pieces are there. I'm just missing the link!
I have a network (192.168.x.x) that I want to keep closed and private for the most part. I need however to get access to some files generated on the machines in this private network. So I first tried putting two cards in a machine running centos 5.2 and connecting one to the private newtork and the other to the public network. This worked somewhat but I was not able to see this bridging machine in the private network because I could not run 2 samba instances on this machine ( I need one for the public network). So I setup xen on a machine with the 2 NIC's and assigned one card to the host dom and the other to the guest dom which was connected to the private network.
This worked ok, but the only issue was the shared disk space. I couldn't use nfs because each machine operates in a different subnet and I don't know how to export a nfs drive across domains. So I created a logical volume on a disk and mounted this in both domains.
Here comes the question now. This works some times,. but at other times I copy files from the private machine to the shared volume but i can't see them from the other domain. Also sometimes the guest domain which houses the private network server hangs during boot up saying that the logical volume has been assigned and cannot be mounted.
1) Is what I'm doing using logical volumes across domains legal (best practise, etc)
2) Is there another way for me to achieve what I want (sharing a disk partition across domains).
I have installed ubuntu netbook addition and all is good, but when I try to connect to internet I get comcast(my service provider) site. Which means I am connecting to outside world just need to know what to enter in Search Domains field.
All my pc's/laptops at home have 2 DNS names entered for ipvr4 listed in the field but no Search Domains field value specified and it works great off of wireless router.
Well here when I go to IPvr4 tab it seems like I am required to enter value in search domains field. The question is what do I enter there COMCAST domain? Like this one: hsd1.il.comcast.net?
Anyone can point me to a document, page, or something that will tell me exactly how to implement DNS step by step. I don't mean just the concept, i.e. you'll need two name servers, and to download BIND, etc. NO, I mean command line commands and all. Step 1, step 2, how to register the name servers, how to resolve different domains, etc.
I'd really appreciate it, as I need to implement internal DNS and external DNS for my company soon. Our set up is pretty standard: Firewall, DMZ, Solaris/Linux/Windows servers, and Windows clients, etc.
At home we have a small home network, but it is very slow. I believe it is, because some computers are placed in a workgroup, called WORKGROUP and others are placed in a domain called TUE. The domain is because many of the laptops at our house also have to work on our university, and I can't simply put them in a workgroup.
The reason why I believe it is slow because of this, is because file sharing between the computers in the workgroup goes with 5 MB/s. File sharing between a domain computer and a workgroup computer goes as fast as 160 KB/s. This is the upload speed of our internet here. How to make the connection with the domain computers the same speed as the workgroup computers? I can not simply put the domain computers out of their domain and in the workgroup (as explained before)
Our network looks as follows:
Internet

That's the message I see briefly right before I am booted into Ubuntu Meerkat. It's right after the boot menu and the boot into Ubuntu begins and the screen is still black when that message appears.
View 2 Replies View RelatedI run a few programs that are very resource intensive, and although my computer has 4 cores, it keeps "freezing": it still works, I can see that my downloads keep on going, it's just too slow to show me a terminal screen so that I can kill whatever program got out of line.
It may be a bit complicated, but I suppose that there should be a way to do it: how can I keep some "cpu usage" from being used? I don't know, maybe reserve a core for management? Or throw the problematic programs in a "box" of limited processing power?
I'm sorry if this is a really dumb question, I'm a bit of a noob, but that would help me a lot. Of course, if someone has a better suggestion for my problem, I'd appreciate it very much.

View 2 Replies View RelatedI have several environments in which I am using Thin Clients as terminal emulators to Red Hat servers. I have been deploying Thin Clients for the past few years to replace old WYSE dumb terminals. One problem I am having is that the dumb terminals were serial so they were on a specific tty port. The Thin Clients however connect on the first available pts port, I really don't have control over the port each Thin Client connects on, other then possibly making sure they are always started in a certain order, which isn't a feasible option. What I am wondering is if anyone knows a way to control which pts port a thin client connects on; I'm guessing it would have to be by hostname or IP, I just can't figure out how.

Calculating the available bandwidth methods IGI/PTR,PATHLOAD,SLOPS,PACKET PAIR...
I gone through above methodogies ,when i finish one methods(IGI/PTR) i came to know,one application should run in client side and another application should run in server side (i.e,) Internet Service Provider side,
In IGI/PTR method ./ptr-client.c & ./ptr-server.c is there .,if we want available bandwidth,I Should run ./ptr-client.c (in myside)correspondingly ./ptr-server.c then only we wil get a availble bandwidth...
My need is without run any application on the server side ./ptr-server.c like that,but I should develop the application only on client side (in my routerside based on linux)..
1:whether it is possible to get the available bandwidth run application in client side only?.if possible. how i implement the code in client side( only )for getting the available bandwidth ...whether any source code is available?...
