Iptables - Simple Cofiguration
Dec 15, 2008
I was able to reverse the ruleset I had earlier. I have read more and added the following rules set:
target prot opt source destination
ACCEPT tcp -- anywhere anywhere tcp dpt:ssh
ACCEPT tcp -- anywhere anywhere tcp dpt:http
ACCEPT tcp -- anywhere anywhere tcp dpt:smtp
ACCEPT tcp -- anywhere anywhere tcp spt:smtp
ACCEPT tcp -- anywhere anywhere tcp spt:domain
ACCEPT udp -- anywhere anywhere udp spt:domain
ACCEPT tcp -- anywhere anywhere tcp dpt:https
ACCEPT tcp -- anywhere anywhere tcp dptop3
ACCEPT tcp -- anywhere anywhere tcp dpt:domain
ACCEPT tcp -- anywhere anywhere tcp dpt:smtps
ACCEPT tcp -- anywhere anywhere tcp
dpt:cvspserver
ACCEPT tcp -- anywhere anywhere tcp
dpt:webcache
ACCEPT tcp -- anywhere anywhere tcp
dpt:distinct
ACCEPT all -- ip-XXX-XXX-XX-XXX.ip.myserver.net anywhere
DROP all -- anywhere anywhere
I tried to follow this HOWTO:
[url]
It appears to work on most ports. However, when I try a web site on that
server, port 80, it starts but never finishes - never goes to that page. The progress bar looks like it's almost finished but never gets there.
I need to be able to:
check and send mail
serve web site
ssh/WinSCP
port 9999 needed as well as 8080
run DNS
Does that rules set look right?

I execute the following commands, in the following order:
iptables --flush
iptables --zero
iptables -A INPUT -s 218.65.12.161 -j DROP
will that last command successfully ban that IP until reboot?
If not, what needs to be done? I can't access my site if I don't flush + zero iptables first but I need to be able to ban with iptables.

Because i have couple site hosted by both hosting company (DTH=downtownhost and TCH=totalchoicehosting) and have positive experience with them i needed to make decision who will be hoster for my new project.
The problem was by both company and by 99% others that traceroute command is not enabled by default and it is essential for my new project.
After exchanging a couple emails with both companies DTH was winner again because DTH allow on shared hosting traceroute command (in situation that you need it).
Answer from TCH was that only on VPS (semi-dedicated) is traceroute command possible and not on shared envirovment.
I must again praise DTH for the way how they handle with their customers and that they are ready to do everything for their customers. Not wonder that they are one of the greatest hosting company.

where I can get a simple SSL certificate for my web hosting business? So my customers feel safe on submitting their information. Is the standard SSL from GoDaddy pretty good?

So I was trying to run a backup process in Plesk 8.1 and the whole panel froze up on me (it's happened numerous times before).
Anyway, since the panel was all frozen up I just went into SSH and did a simple "reboot" (also, as done before many times). Only problem is, this time after I did the reboot the server never actually came back online... it seems to be locked up or something, I have no idea what.
I called my host and they are looking into it but they have no idea what's going on either and it's taking them forever to figure it out all the meanwhile my sites are down.... this isn't good.
Does anyone have any suggestions or advice as to why this could be occuring?

Can you see if my site will load for you:
[url]
Then (if it loads) post the stats from the bottom of the page:
Page creation time: (Numbers)
And:
Your Os:
Your Browser:
Some people say my site won't load or is loading slowly for them, but I have no one to test it, thanks. If possible, I need quite a few tests.

when I get a server it comes with cPanel and I don't have to do much to get it going, but this time I don't need all the bells and whistles. What should I do to get a server with only CentOS to start running a pretty simple web server that just listens on whatever ip? I just want it to run php,mysql, and a web server which I know how to setup already. What I want to know is what else is necessary to setup? Resolvers, the hostname, bind, named, etc?

I cannot express this enough: Stay away from Simple Helix!
We switched to them after our last $5/mo host kicked us out without warning. Simple Helix is just as bad but more expensive... Their support system is awful. Our website is down at least once or twice a week without any warning or support.
You cannot talk to anyone in their support. You have to write a stupid ticket. Then you wait and wait until someone decides to open it and read it. The if you are lucky, they will respond to it. But you gotta be REALLY lucky that they respond with something useful. Most of their responses are irrelevant or do not make sense.
Last week my website was destroyed because their server crashed. When i wrote a support ticket, which was answered 24 hours later, they said that I did it! Then they told me I had to pay them to fix the problem. Only when I contacted their corporate offices they got their admin working on it. Even then, it took over a week to fix the website. The admin would only respond when he wanted and sometimes he would ignore my messages to the point where I had to open new tickets to tell them to take care of my original ticket.
JUST STAY AWAY! WHATEVER YOU DO-DO NOT GO WITH SIMPLE HELIX.
It seems nexcess.net is a good host and I am going to be calling them tomorrow to talk to them about switching to them.

I've recently re-designed my website to WP and my host which I've been with for the last 5 years has suspended my site for system abuse. Is WP no good? They suspended it last week so I added a cache which they said had fixed it, now they've comeback and said its still overloading. My site gets around 500 visitors a day. Does this sound right?
I've already had to ban google bots from my forums because of overloading in the past.
Can anyone recommend a host that can handle a wordpress site that gets 500 visitors a day?

I am just posting a simple reviewof my experience with MKOH (My Kind of Host)
Great people they seem from the e-mail correspondences. Just one problem with there automated message upon account setup. Include the name servers.
The support has been prompt during the day and it's been a few hours since I've e-mailed them and heard nothing back and it's nighttime which sort of worries me for the long run. No one around at night.
So, I ordered this morning 10PM EST and the acccount was setup within normal business hours. But since then haven't received a response with the nameservers. I could assume it's ns1.mkoh.com and ns2.mkoh.com but that's most likely not them or they could have multiple servers or even a datacenter or offshoots so I can't assume.
Again, great during the day. Night a bit rough. This is day 1. I will let people know here if this thread isn't deleted what happens after tonight I just think support at night is important in this industry.

to set up a little server that will have LAMP installed on it. All it will do is host a small program that runs on PHP and mySQL and will only be used on an office network with about 50 employees.
How well would this server run if the hardware was rather modest (667Mhz, 128mb RAM, 10GB HDD)?

I've had to edit alot of zone files and have been trying to find a solution to ease up the work. So far I found a nice perl command which can search and replace pretty efficiently.
I was wondering if anyone here knows something simple to search for a number. Lets say if the number was bigger then a specified amount (say 1 million) then it will add a 1 value to the large number. Of course this will scan through all the zone files in the directory and add the 1 value accordingly.

I bought a webhost from hosting provider. But ImageMagick does not work. Hosting provider said ImageMagick is installed.
But ImageMagick still do not work! I think it is not installed properly [url]
So, I need any simple test script to test ImageMagick if it works or not. I need real visual evidence for hosting provider to tell him that Imagimagick is not properly installed. I looked through this site but didn't see any test script.

As I am about to complete the move of our business sites over to our current Simple Helix account from an overloaded, bogged down VPS, I had noticed a few negative reviews on the forums.
I have had SH account for quite some time. It was hosting a simple PHP page that I couldn't put up on our old ASP server. I had never had any issues with it and when we began experiencing problems on our other sites, we chose to begin the move to SH.
I had heard a few grumblings about it being sold, etc, and actually had our sites moved on to the new servers recently.
After a few initial issues after setup on the new server it has been very reliable and extremely fast.
Before I complete the move, I wanted to request a few more reviews.
We are different than the usual SH customer in that we are not hosting Magento. We are a very professional business looking for a reliable, managed hosting solution. I am having trouble defining a line where it makes sense to switch from shared to dedicated managed hosting.

How do go about discovering where your bottleneck is with an openvpn setup?
Ive setup openvpn on my remote server and have setup everything so that my desktop clients (vista and ubuntu) at home can connect and have all internet traffic directed successfully through the tunnel.
Im using it to stream video that would normally be inaccessible outside of the UK whilst im in Japan i.e. iplayer.
The problem is its oftenvery choppy and unplayable. Though its good when england is sleeping.
Im new to servers (not to stuff like programming though) so dont know where the problem lies, how to find it out or even where to start looking. For example things ging through my head
Is it the limitations of the vps? How do i find that out? my plan:- vps1
Is it the location of the actual server in the uk? How do i know if there are any better coming from japan?
Is it my configurations? How do i pinpoint that?
Or is it working as good as it can be? How do i know that for sure?
etc etc
What would be your process of elimantion? Quick checks that would tell you which direction to move forward in?

A friend of mine basically just wants to get his business on the web. He wants a website that is entirely informational (e.g. no commerce or anything like that). Basically a home page with a couple of links to download some documents and some contact info.
He does not have a domain name, so he would need that.
And the person wants an easy to use website designer for this simple site.
My initial thoughts were:
Microsoft Office Live - but that doesn't seem to be totally free anymore.
Wordpress.com (I am not sure this would work as well especially if you wanted to post documents or something)

We have a 1 server setup. Right now all dns, web, and email are hosted from this single box.
We wish to bring in a server2 and have dns cluster setup, this would also host mirrors of email and web sites from server1.
What i want to know is what is the best way to setup the DNS cluster/nameservers?
would it be
ns1.domain.com pointing to server1 dns
ns2.domain.com pointing to server2 dns?
if that is the case and lets say server 2 goes down, wouldnt that mean the 50% of hits to the web site would be denied as ns2 is down? The reason i ask this is that to my understanding nameservers do not have priority, they are randomly hit.
I am trying to provide some small bit of redundacy.

I currently dev locally on a cobalt RAQ (ollld!) and would like to upgrade this setup.
I'm looking for a simple way of getting a linux system setup for internal dev work with the basics... mysql, apache, php5, and some kind of version control - subversion / cvs.
Are there any linux liveCDs that I could use to make something like this quite easily?
For our production server we use plesk, so a control panel similar to that for setting up new dev domains would be useful. Open source of couse tho.
