    Hi, I would like to discuss what options I have to block IP"s who launch 100+ simultaneous requests to a single page within a minute and drive up my CPU load to, I need someone to help me write some IPTABLES rules that can help me to block such requests and I need to figure out how to calculate the best settings (e.g. how many connections are ok, how many not). If you have experiences with IPTABLES rules and know how to prevent such nasty DDOS attacks, please bid.ThanksOliverKeep in mind I am familiar with modevasive, ddosdeflate, CSF, limitipconn and many many other, so if you have knowledge in this field and suggest another solution that is ok, but definitely need some good IPTABLES rules.

    I need at daemon that can run under debian (scripting language unrelevant, as long as it works).It must listen on a given port - (e.g. 10001) and sort the incoming traffic. If the traffic comes from IP x.y.z it must redirect to x.u.a, or if traffic comes from x.x.x it must choose random from array of IPs to redirect traffic to.The script must be easy expandable, so it is easy to add new ip-sources and redirect sources/random-arrays.The daemon should not analyze traffic in any way, just redirect it to a given IP based on incoming IP

    Hello,About 2-3 years ago you proposed me to create a nice way to stream and have my videos secure.I told you that I will contact you.It"s about this project: would like to implement this solution:"Faster solution (if your load is high - over 2-3.000 downloads a day):1) you should have a VPS server or dedicated one2) you need one additional IP from your hosting provider3) another web server (nginx) should be installed on that IP and configured to validate tokens and server static content (video files). Nginx is extremely fast in processing static files and it is used by all major download sites like rapidshare and similar.4) finally, the script should generate correct tokens and headers :P "Would you like to do it?BTW can files be streamed that way? Will you do it that way that they will be streamed? So people can jump from one place on video to another? I"m using JW player on website.My hosting company: dreamhost.comOh and file server is on but website is on another server in Poland netmark.plI have VPS for files, and typical shared hosting for website.Best regards,Arkadiusz Wlodarczyk

    Hi,I have a Fedora 13 x86_64 machine (4GB RAM) which should act as our mysql server and I am looking for someone who tells me, how to compile and install mysql 5.1.50 best.The biggest problem: The data directory will sit on a NFSv4 server! (It is not shared! So this mysql server is the only one who writes/reads to this NFS file system.)We need to support MyISAM and InnoDB (and nothing else)! (So one of the problems is, how to make sure that after a transaction is completed the system is sure the data has been written onto the NFS servers disk...)We already have some other mysql servers which we would like to aggregate to this new one.(This aggregation is not part of this project! Only the setup is needed! We have around 200 databases with a total of 130GB data. Yes, maybe later we will add more memory.)I just want to have a clever start from you and some hints for later improvement.It is totally clear to me that we can"t setup an optimized version right now for our load!I just want to have a good start, so we are able to optimize later...This small project is for someone, who has much knowledge in mysql AND NFS.No, I do not want to discus if that setup makes sense. :-)Best regards!

    I am looking for a virtual filesystem for linux, similar to UnionFS (Each file on this &quot;virtual&quot; filesystem actually points to a real file mounted elsewhere).There are two ways I can do this; I will take whichever is cheaper. Please state in your bid which option you will use.OPTION 1 - PerlFSI will write most of the logic for this filesystem in Perl.The line in fstab will look like:Some::Perl::Module /home/mountpoint perlfs option1,option2,option3 0 0I will write a Perl module (following the function signatures you specify) which will implement stat and directory listing functions, as well as being able to provide the path to the &quot;real&quot; file for any path under this virtual filesystem. This should include a mechanism for options to be passed through to my perl code.OPTION 2 - Enhanced union FSFor this option, I will expect a filesystem similar to UnionFS. The first column in fstab will contain the path to a configuration file. This will provide the same options as UnionFS, plus some extra stuff. I should be able to designate &quot;tags&quot; for part of the filesystem. For example, if a file &quot;foo/bar&quot; in the underlying filesystem has tags &quot;baz&quot; and &quot;chii&quot;, it will appear in the union fs as &quot;foo/bar&quot;, &quot;baz/foo/bar&quot;, &quot;chii/foo/bar&quot;, &quot;baz/chii/foo/bar&quot; and &quot;chii/baz/foo/bar&quot; (all effectively the same file). I should be able to specify directory names which will automatically be converted to tags. Below a certain number of entries in the directory listing, tag directories will not appear. If the size of a directory listing would exceed a certain limit, only tags will be shown. I should also be able to apply regular expressions to change filenames; to specify configuration directives which only apply to files matching a particular pattern (or to part of the directory tree)Please ask if there is anything unclear in this, I&quot;m not good at explaining.
