Server :: VPN Setup - Dedicated Or VPS / Bandwidth?
Jul 10, 2011
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 am trying to setup a sendmail server on my dedicated server. It was pre-configured to use exim from cpanel. Is it possible to use exim for all emails from a a certain domain i setup on the server and sendmail for others?
ex.
domain1.com -> exim
domain2.com -> sendmail
If it is possible can someone let me know how i would go about doing this? If it is not how would i disable exim and use sendmail for all mail?

I currently want to set up a network with 2 Ubuntu servers (mail and web) in a DMZ in order to separate them from an internal network. I want to use a dedicated Linux firewall. This firewall will have 3 network interfaces on it. One network interface will connect to the external router/modem (router and modem in one box), one interface will connect to the DMZ and the other interface will connect to the internal network. The router/modem lets you put, I think it's 1 or 2, interfaces in a DMZ.
But, when I think of any of the dedicated firewall's or servers' interfaces it doesn't make sense to me to put any of them in the router/modem's DMZ (I think it would be better for the dedicated firewall's and the servers' interfaces to have static private I.Ps ie 192.168.2.4 etc right?). What I mean is that even if, as far as the router/modem is concerned, none of the interfaces were in a DMZ, the area where the servers are would still effectively be a perimeter network and with such a set up would still be, effectively,a DMZ, right?

The /var directory is 97% full on my dedicated server:
I would like to know if it is safe to clear it and how to clear it (assuming it will not disrupt/kill server services to do so).
I have Matrix control panel so i can view the storage etc but it does not have an way of clearing the /Var directory.
I have Putty Access to root but do not know which command to use.
I found a few threads but the information is not clear to me as there seems to be an assumption of basic knowledge I don't yet have.
My linux/ubuntu support that usually does this kind of thing for me is away and not contactable and my server is grinding to a halt and unable to store/send email.
I have only a very basic understanding of command line but really need to get this sorted ASAP.

Is it possible and SAFE to delete files via FTP from the /var/cache/apt/archives?

When you need to change something on the server you can hook up a monitor and a keyboard and do it through the console.
I would like to hook up an external monitor in this fashion for a desktop. The current video card can only support a single display. So I was hoping there was someway to use a second monitor as just a permanent console since simple text shouldn't require a video card?

I want to install Webmin on a dedicated remote server. I keep reading different blogs/tutorials etc about installing webmin on Ubunto server 10.10 but it seems too easy to be true. There is never any mention of requirements etc. I did read that even perl isn't needed pre install now and will install with webmin.But do i need to install lamp etc first or does it pull these in when Webmin its installed?

I have set up a Virtual machine on a dedicated server from 1and1. I hoped to use a bridge to give the vm direct access to the internet but 1and1 do mac filtering and so the only option is to use NAT.
I used Virtual Machine Manager on my Ubuntu 10.04 machine at home to install Debain Lenny on the vm on the server using KVM and all went well. I put it on a virtual network 192.168.100.0 and i can access it from the host and i can access the internet from the guest using NAT that libvirt set-up.
I bought another ip address from 1and1 with the hope of forwarding packets to the new ip address 11.22.33.02 to the guest vm.
I have tried all sorts of routing rules using iptables without any success.
my virtual network is on virbr1 the guest ip is 192.168.100.50 my external network device is ip say 11.22.33.01 on eth0 with the secondary ip say 11.22.33.02 on eth0:1
Here are the latest rules i tried:
Quote:
iptables -t nat -A PREROUTING -d 11.22.33.02 -i eth0 -j DNAT --to-destination 192.168.100.50
iptables -t nat -A POSTROUTING -s 192.168.100.50 -o eth0 -j SNAT --to-source 11.22.33.02
iptables -A FORWARD -p tcp -i eth0 -o virbr1 -d 192.168.100.50 -m state --state NEW -j ACCEPT
iptables -A FORWARD -t filter -i eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT

I am currently having an issue attempting to set up a dedicated server for source games (TF2, CS:S, L4D2). The required port (27015), along with most others, appears closed to the rest of the world and upon a port scan with DMZ hosting on (therefore no router interference between the internet and my computer) only a few ports are open (80, 139, 443, 445). My ISP does not block ports so therefore the only issue I can find is with my computer running Ubuntu 11.04. I have ensured that all traffic is allowed via iptables and I can't think of anything else that would have ports closed.

Been a while since I last posted here, though I stop by often. Unfortunately I find myself in a bit of a pickle again. Here's the situation. I have an RHEL3u5 server running Apache 2.0.48 and an equivalent of Tomcat and JBoss. IBM's WebSphere Application Server 6.0.2 to be exact, the Apache also being one of their flavors (IBMIHS).
Everything's been going dandy since forever, but lately the httpd processes seemingly just hit a brick wall of some unknown kind. Checking the /server-status page reveals a whole lot of piling up "waits".
The funny part is that the load average rarely goes higher than 1.0, I/O seems within limits, memory usage as far as I can tell seems fine, disk usage appears all good... I would've felt more at ease if something did shoot through the roof, but there's just nothing to go on. It's definitely Apache getting its knickers all in a twist as well since I can access the servlet engine's web GUI just fine over its dedicated port via browser.
Here's what I noticed so far: Apache processes rise steadily to over 35 or so, after which it all goes south fast. As a result and as a temporary fix, I've enabled a cronjob that checks the amount of httpd processes and just restarts Apache if they're above 28. So far this seems to keep things sort of happy, but obviously I'm still twitchy with the overall state of affairs. I do not have the settings immediately at hand, but here are some further details so far:
Server spec:
8 x Xeon CPUs
8GB RAM
I'll post further details probably on Monday, specifically key portions of the httpd.conf file.

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 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?
