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...

If your machine is connected to the Internet, you'll probably want to disallow ssh password authentication (which is advised but not mandatory). Edit the /etc/ssh/sshd_config file and change/add the following lines:
PasswordAuthentication no
AllowUsers nx
Don't forget to restart the sshd daemon after making that change: service sshd restart I already have PasswordAuthentication yes in my file as I need it to login to the server through ssh. Do I just skip that line and only add AllowUsers nx mynxuser at the end? Also, I followed the rest of the manual and when I tried the client on Windows it failed: I put in a user and password to login but shouldn't it be using the key instead? I think the problem is related to the above due to:

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 use Fedora 12 and newest free NoMachine NXServer. I have installed all three packages (nxclient, nxnode and nxserver). I'm running sshd on port 22. When I try to connect to my machine, everything works fine, then
I see big red M and then is all black.

When I look the Services panel, nxserver is listed but shows as "Service is Dead". Does this mean anything specifically? Could it be related to firewall or security issues? Right above it a related program to nxserver, nxsensor, is listed and it's shown as operational.
Same thing here in my Services panel. Just getting into using NX...the display seems near Win RDP quality over the home lan. I'm now trying to get the sound to work. What is this 'dummy output' in my Sound preferences and where did my sound cards go? I have one onboard sc and a PCI card, neither recognized via the NX client session. Looking to get ESD going which might be the issue.
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.
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.

I'm a noobie with nomachine and have no idea why the authentication is failing so I'm open to any suggestions. I've tried stopping and restarting both ssh and nxserver and I've tried regenerating keys. I can ssh to the host but nxserver doesn't work.
So: On the VPS / Dedicated Server Linux wich 3 users created. How can I limit bandwidth each in a separate? For example first user speed 1 MB. 5 MB second and third 10 MB. Expect some clear answers. Regards, Silviu!

View 1 Replies View Relatedwhen 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 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?
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?
View 4 Replies View RelatedI 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 (?).
View 1 Replies View RelatedI'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.

The good news is: basically it works. I can connect and get the desktop. However, I have some trouble with the keyboard. Up and Down arrow keys do not work. The up arrow triggers a screen snapshot. The down arrow key does nothing. I tried to connect using qtnx as well. This does not work. Result is:

View 1 Replies View RelatedMy server has been the repeated victim of bandwidth attacks: any large file on the server is downloaded repeatedly, with the goal of pushing the server over the provider's bandwidth limit. How can I lessen the effect of these kinds of attacks with IPTables or APF? For example, can I set the server to: Is this possible? Is there a more effective way, and can a firewall even do this? My web server is Lighttpd, perhaps I can place such a rule directly in its config?

Does squid automatically split bandwidth between connected clients? I'm wondering if someone was downloading a lot of data and someone else connected whether it would split the access 50:50 between them? I have 1 user that is using a lot of bandwidth but the server doesn't seem to split it up between all connected clients so others are receiving slow access. I don't have this client's IP address but I do have ncsa auth connected. Will delay_pools work with an ncsa username?

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.
