Are there any free Fire walls available for CentOS 32 bit ?
I heard APF Firewall . Is that APF Firewall free ?
Is that APF Firewall has enough security ?
Is that slow down my server?
(p4 -D 3GHz / 1GB Ram)
Is there any sense to upgrade to cent os 5?I mean,is there any critical benefit which will increase server performance if i do that.I noticed i can upgrade over ssh but since that will generate downtime i wonder is there a sense to do that.
View 1 Replies View RelatedI have just taken delivery of a shiny Windows 2K3 server from a2b2.com and wanted to secure it so that only remote desktop and port number 3306 from certan IP address are allowed to connect to it. I would also like to have NO outgoing connections allowed at all.
My questions are 1) Is this able to be done? and 2) Approximatly how much would it cost.
I am about to sign up for a VPS host which doesn't seem to offer hardware based firewalls which means that I am stuck with software based ones. Perhaps I am being old fashioned, but this do make me a bit nervous, as I have the impression that a hardware based firewall is better (of course assuming correct configuration and such)....should I be worried? Is Windows Firewall to be trusted or should I look for something else? My concern isn't only if the firewall will stop any attacks or not, but also at what cost, considering CPU, memory etc. Any comments and recommendations would be apprechiated. I'm not NASA or anything, so I don' really think that the worlds hacker elite is going to come after me, but from what I see in the logs of my current firewall, there is a lot going on on the internet these days and it isn't all good.
View 14 Replies View RelatedI'd like to know what the current "best practice" thinking is with regard to hardware firewalls. Are they really necessary for a Linux server running a solid iptables-based software firewall? Or do they simply add another potential point of component failure?
What are the pros/cons to deploying a hardware firewall vs. going iptables-only on the server?
I am in the process of looking for a firewall to install on my windows server.
However, which firewall is the best?
Is it better looking for a hardware firewall (Cisco 5510 Firewall) or a software firewall (Quick Heal Firewall Pro)?
IPTABLES(Linux Firewalls)
Use Of Iptables?
Filtering packets based on a MAC address and the values of the flags in the TCP header. This is helpful in preventing attacks using malformed packets and in restricting access from locally attached servers to other networks in spite of their IP addresses.
Firewall also keeps track of each connection passing through it and in certaincases will view the contents of data flows in an attempt to anticipate the next action of certain protocols. This is an important feature in the support of active FTP and DNS, as well as many other network services.
How IP Tables works?
All packets inspected by iptables pass through a sequence of built-in tables (queues) for processing. Each of these queues is dedicated to a particular type of packet activity and is controlled by an associated packet transformation/filtering chain.
There are three tables in total. The first is the mangle table which is responsible for the alteration of quality of service bits in the TCP header. This is hardly used in a home or SOHO environment.
The second table is the filter queue which is responsible for packet filtering. It has three built-in chains in which you can place your firewall policy rules.
a) INPUT Table b) OUTPUT Table c) FORWARD Table
General Syntax of the iptables is as follows:
IPTABLES -A {INPUT,OUTPUT,FORWARD} -p {tcp,udp} --sport(dport) -s {ip} -j {DROP,REJECT,ACCEPT}
To Block the incomming ip:
IPTABLES -A OUTPUT -p tcp --sport{1..65535} -s {ipaddress} -j DROP {REJECT}
To Block the outcomming ip:
IPTABLES -A INPUT -p tcp --sport{1..65535} -s {ipaddress} -j DROP {REJECT}
You can also use --dport instead of --sport & you can use -d instead of -s which specifies source or destination respectively.
We are upgrading to a managed server from a VPS. Our main concern is security as we process customers' confidential personal information but don't have large volumes of traffic. Our application developer is recommending the following config:
Firewall --> Web/App Server --> Firewall --> DB Server
The logic being that if the first firewall is breached at least they don't have access to the DB.
Is this really critical or do you think we can start with:
Firewall --> Web/App/DB server?
Obviously budget is a concern and since we will have low traffic for the next few months it seems silly to pay double if it isn't really needed?
Do I have to reinstall or re-config firewalls (BFD, APF, etc), eAccelerator, etc after I re-built Apache?
View 9 Replies View RelatedI have a server in our office which is used as a share drive. Puts all accounting docs on it ect. After 6 or so, it will loss all conectivity completely. Yet the server still stays on. We installed everything in all packages on the server including it graphical interface. We havent mucked with any of the powersavings so what could it be. Also there is nothing plugged into it eg screen,keyboard and mouse. All that is connected is the power cable and the ethernet cable. That is it.
It is directly connected to a belkin wireless router

I noticed with every new cent os server there are different mirrors for cent os repos.Since on each cent os repo file is same,how does it pick which mirror it pick?I ask beacuse latest server has picked one extremly slow edu mirror which is not just slow,it also timeout,and it may extend update to 2 hours instead 5 minutes which usually will take.So how do i change base mirror on base cent os repo?

And will kloxo work on cent Os 5.3 64bit?
or atleast 32 bit?
how to check which version of cent os is used?
my friend ordered an vps with a host, he ordered 5.3 - 32bit but some how I feel he has been provided with 5.0 version by the host, I didn't know how to confirm it, when I checked his hypervm, this was the cent os details provided:
Ostemplate: centos-5-i386-hostinabox576
there is rebuild option in the hypervm and in tht when I look out,here it shows the following:
[url]
what my friend exactly needs is a cent os 5.3 - 32bit system, so if he selects cent os 5.3-ix386 (full) will it install with cent os 5.3 ?? he doesn't want kloxo to b in there auto, he/I can install tht,

Do you think if a company offered free web hosting and free domains people would snap them up like there is no tommorow?
Also does anyone one how much ICANN acredited registrars pay ICANN when they register a new domain?

What does everyone think about free hosting? Is there always a catch or are there really some good free hosting?
View 24 Replies View RelatedI need a good and free hosting with php/mysql support for a personal site i am making.
All the site is database driven so the host needs to have fast db connections.

I've made my first website and I'm trying to find web hosting that is free and that it will also allows me to transfer my files through ftp directly through an ftp server. (ftp.example.com)
I've tried using the one for freewebpage.org but it doesn't work.. I tried it using port 21, 22, and 80 in both frontpage and filezilla and they didn't work.. I guess it's the ftp server that isn't really working, or the information they provide is inaccurate.
I have been searching for free ASP.net hosts since last few months and I didnt have much success in it,
so far I have tried these sites none work ...
Current server has 4 GB ram, all buffered by linux.
Code:
total used free shared buffers cached
Mem: 4054 3917 137 0 99 2139
-/+ buffers/cache: 1678 2375
Swap: 4094 0 4094
The buffer has 2375 MB of free ram. However this is a heavy mysql server. I want the empty ram be used by mysql so it becomes faster.
We are currently moving to a 8GB ram server, and the free ram will be around 7 GB if we use the exact same configuration. I want the free ram to be 1 GB at most, why pay for 8 GB ram if I'm going to use a fraction of it?
What optimizations should I attempt?
I know about harddisk I/O bottlenecks, I have two SATA drives in the system, and a SAS drive dedicated to mysql, that's all we can afford currently.
All mysql databases are for SMF forums, and currently using MyISAM tables. Switching to another storage engine is a possibility, if it won't create problems in restarts and hot backups.
Does anyone know where I can get a free FTP program?
