I don't have a clue what WhiteHat is talking about in this article. Could some of you technical people please decipher it, and explain the vulnerabilities in language that webmasters can comprehend who aren't computer scientists? Because then we might be able to figure out how to protect our web sites from being hacked.
I've got a strange situation here. We have some software which we run on multiple servers. As of today the software is using 100 percent (sometimes more) of the cpus.
Here is the result from top. It's usually far worse using 100 percent of both cpu's almost all of the time. I just restarted, but the server load is climbing to 20+. Any idea how I can figure out what is going on? The same software on two other identically configured servers runs fine. This server has had no problems for over 6 months, but suddenly this started today. The server is a dual opteron with 4GB of ram. The databases are innodb thus the high memory usage for mysql (innodb buffer pool size)
i have a question concerning SSL surfitup.us is my domain. Now when you go to it, it doesnt show the lock button on the bottom to show that it is secure.
I would like to be able to use https.
In the site i have my icon fro go daddy saying is real.
I installed ImageMagick via yum on my CentOS 4 box. It is version 6.0.7
When using gallery 2, I received a warning message stating that this version is vulnerable (low risk but still) and was wondering if there was anyway to update this past 6.2.2
I tried to do it manually by compiling from source but the composite part of ImageMagick never works...the identify and convert are recognized.
Is there an easier way....a RPM for RHEL 4 I could use?
Every now and then I'll run into a website that has a message that says it was hacked by a certain hacker. How exactly do this? Do they hack into the actual server or do they somehow get a hold of the website owners FTP info?
how many websites can stand on VPS with following configurations?
I'm asking this because Can I install whm reselling script like whmphp? or WHM Reseller creator?
It enables to create master reseller and whm reseller respectively. So there will be huge number of websites, databases, emails hosted on VPS So which one to choose?
1. Disk space - 10 GB Bandwidth - 200 GB Burst. RAM - 256 MB Gurnt. RAM - 128 MB Max CPU Usage (per CPU) - 80 % OS - CentOS 5.3
2. Disk space - 20 GB Bandwidth - 400 GB Burst. RAM - 512 MB Gurnt. RAM - 256 MB Max CPU Usage (per CPU) - OS - CentOS 5.3
3. Disk space - 30 GB Bandwidth - 800 GB Burst. RAM - 1024 MB Gurnt. RAM - 512 MB Max CPU Usage (per CPU) - OS - CentOS 5.3
I have three domains that I want to host myself on my own computer. Two are temporary sites that I only put up on Memorial Day weekend for the Detroit Electronic Music Festival or Movement 09 to direct people to my after parties and the other site is a two page bio site for myself. I have a very tight budget this year and I can't afford to pay for web hosting all year round when these are only temporary sites even though I own the domain names all year round. I do know some of the promoters for the festival do the hosting themselves.
I'm not sure why my brand new dual proc quad core xeon 2.5ghz harpertown gets time out when the server load is under .5
Like it'll be running ultra fast and suddenly, I can't get into ssh, whm, my websites or anything. When I ping it, no reponse. Is it because it restarted itself?
Just out of curiosity, do the big boys deploy hosting solutions that are different from the ones we know?
They never complain of Network Outages or Hardware failure. How come the likes of Yahoo, Facebook, Youtube and the others are always there any second you need them?
what are all the different types of websites? i know there's e-commerce, forums, blogs, personal and etc. what are some other types of websites people start?
This is a little wierd, I am not able to see any of my websites on my home network, but from anywhere else it seems too load just fine. Even when i go through a proxy site they load. I'm still able to get to WHM and cPanel from my home but the websites themself do not load.
this started happing yesturday and after a few hours it seemed to work again on its own.
i have a reseller account with canaca.com the safe mode &security mode are on! and everythings was great! till those hackers bastards appeared! they somehow could upload a php shell files to my websites! and then they deleted everythings in 4 of my websites! i contact my tech support and they restored my websites and i checked that there is no shell files! next day,my websites hacked again and there was i php shell files in them! i deleted those god damn files and i deleted the page that the hackers put in my websites! you security is zero,and we will hacked the entire server.., but after 3 hours the pages returned and the shell files are there! i dont belive that! the unbelivable this is that when i want to run those php shell files the safe mode stoped them doing anythings! so how can those bastards do what they do?how can they ulpload the files in the first place? is there any soultions to this problem! cause i restored my websites about 3 times now and everyting i restore it they hacked it again and again!
I think I broke my server. I was trying to install Zend Optimizer, but it didn't work.
After doing some research, I found out that I needed to disable selinux. After doing so, I rebooted. Then I installed Zend Optimizer and rebooted again.
Since then, all my websites have been inaccessible. I can access my server through Plesk control panel, but connection to my websites just timeout.
What can I do to fix this?
Edit : I can access my sites via FTP as well.
Edit 2 : I tried starting Apache with the following command :
Quote:
/sbin/service httpd start
...but it keeps on telling me that the service is already in use. It seems like TCP is bound to port 80.
i currently have a reseller server in the states but ive seen for the money im paying (and im not using the space actually) i can get a VPS server here in the UK which i can combine for webhosting and other development projects. I am after a UK based VPS for the following requirements:
Host 15 websites
Access the box remotely and dial-in to the box which needs to be configured as a VPN server (the box will act as a router, i presume masquerading on eth0 for the connected vpn clients to go out through the server and onto the net).
Traffic will not be too high, maybe around 75GB per month.
Around 3-4 websites run forums on (small size phpbb) and the other sites are again small and mostly used for email.
I will need full root access and maximum configurability.
Preferably Suse 10 as i have worked with that before but i am open to suggestions on other OS. I need to configure the pppd service and easier this is via the OS the less time i have to dig in scripts and terminal! I wouldnt mind windows but on a VPS this will be a resource drain so i am happy to get more performance from the box by sticking with smaller footprint of linux.
Plesk for website management, or cpanel, i dont mind either way.
I dont however know how much CPU/RAM i will need, what is a sensible amount? I dont think my requirements are too strenuous, what would be a good sensible amount of RAM to select to allow me to host say 50 web sites in future?
I have heard good things on the forums for the following:
a2b2.com cheapvps.co.uk 1and1.co.uk
I know you get what you pay for so i do need something reliable, but if people say the service from the above sellers is good i will go for them as the price is fantastic. It would be great to hear of other recommendations also.
I used to check new websites before dns propagation by adding an entry to windows/system32/drivers/etc/hosts file and used to work perfectly. But now days I think IE7 and Firefox 2 is bypassing the hosts file and the method is not working.
any alternative method to check the website before dns propagation?
I currently have a problem with my websites email going to spam. Most of the mail my website sends out, responses to registration, lost passwords etc...gets sent to spam. I have never used this site to send mass email or newsletters. I was thinking of getting an external hosted email solution, but wanted to know what you thought is the best solution for this and what you use to send out emails from your site.
I remember using a few years ago a site where you could plugin a domain name and a report will run showing if the site was vieable or accessible from all different parts of the worls, I forgot the URL does anyone know abou something like this?
We have an issue with websites load very slowly in a new server (centos) and we recieve an email from the server stating the following:
IMPORTANT: Do not ignore this email. The hostname (ns.domain.com) resolves to . It should resolve to xx.xxx.xxx.90. Please be sure to correct /etc/hosts as well as the 'A' entry in zone file for the domain.
Some are all of these problems can be caused by /etc/resolv.conf being setup incorrectly. Please check this file if you believe everything else is correct.
You may be able to automaticly correct this problem by using the ' Add an A entry for your hostname ' under ' Dns Functions ' in your Web Host Manager
and when we restart "DNS Server (BIND)" or "named" we get as part of the output the following:
view localhost_resolver: received notify for zone 'domain.com': not authoritative
Please find below the contents of /etc/hosts , /etc/resolv.conf and /etc/sysconfig/network:
/etc/hosts:
::1 localhost6.localdomain6 localhost6 # Do not remove the following line, or various programs # that require network functionality will fail. XX.xxx.xxx.90 ns.domain.com ns 127.0.0.1 localhost
I'm going to be hosting my clients websites and I was wondering how to calculate how much bandwidth / space I should make available to clients and also how much to charge for hosting / maintenance.
