So you want to setup a service where random spammer/hacker can trivially DDOS your system? How many simultaneous 5GB streams can you handle? How much will your bandwidth bill be if you send 5GB a million times in a month? --

Catch all for dovecot authentication?
I have the same, create your own dns blacklist. And have fail2ban add entries to it. The only problem I have on CentOS6 is that you need to combine log files for this, but it should be do-able. But I am also for this option, maybe it can be done via this userdb, specify an account where auth is not necessary. I would like to redirect sometimes a user to a 5GB garbage messages mailbox. Or if

can I use CentOS as a antivirus / spam filter / HTTP AV gateway?
Hi all I've been thinking about using CentOS on a Dell R200 server and turn it into a firewall / network monitor / traffic shaper in our datacentre, instead of using a dedicated firewall device. One of the devices that I have been looking at, with my limited budget, is the D-Link DFL 860 - http://www.netdefend.eu/Product.aspx?m=15&ref=DFL-860 It provides AV, SPI, VPN, DOS, P2P, etc

Mail account brute force / harassment
Say for instance you have some one trying to constantly access an account Has any of you made something creative like this: * configure that account to allow to login with any password * link that account to something like /dev/zero that generates infinite amount of messages (maybe send an archive of virusses?) * transferring TB's of data to this harassing client.

[OT] Fyodor terminates SCO nmap rights -- how about Samba?
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 As you all may know Fyodor of nmap fame has terminated SCO's rights to distribute namp with its products. See: http://www.smh.com.au/articles/2004/02/27/1077676955381.html I know this is off-topic, but I am interested in opinions on the subject of SCO using Samba in it's products while they declare the GPL is unconstitutional and invalid.

userdb with LDAP
Hi list I currently having troubles to "connect" dovecot (for proxy) to an existing LDAP. If I got the dovecot wiki right only userdb is needed for a proxy setup where the proxy does not authenticate but just forward to the backend for authentication. So I setup the following in dovecot-ldap.conf.ext user_attrs = =password,=y=nopasswd,=y=proxy,mailHost=host user_filter =

compiz/gl-x crashes my games!
I'm running Mandriva 2007 and like the eye candy of of the 3d desktop but wine is more important to me. Whenever I start with with the 3d desktop turned on though any 3d games I have will either crash or report that I don't have a 3d card. Is there any way round this or am I to be denied the pleasure of the wibbly wobbly windows?

C 7.3 sshd will not reload
Hi, Since upgrading to 7.3 I am having a problem getting sshd to reload after configuration changes. When I issue the command "systemctl reload sshd.service" I get the following error: "Unit sshd.service cannot be reloaded because it is inactive." It is obviously still running because I am connected over ssh to the machine and netstat shows it is listening. (vnewman pts3) #

RDP for Centos 7
Hi, Does anyone know of a good program for doing RDP to windows servers on C-7? The "Remote desktop viewer" program that comes with C7 is not reliable for me. I frequently have multiple long running RDP sessions and the keyboard will stop responding. The only way I can find to get it started again is to restart the program and login to the servers again. In addition, I cannot find a

Mail account brute force / harassment
Marc, There is a strategy loosely referred to as "choose your battles well" :-) Let the others bother with their own problems. If you can, hack the server and dump the 500GB - you'll be using resources transferring the 500GB as the other server receives it. Two servers wasting resources because you think you are punishing an offender! On Thu, 11 Apr 2019 at 13:43, Marc Roos

Ask about arm-asm perfomance
How big is difference between encoding speeds of libspeex compiled with arm-asm, and without it? My application is written in EVC++, but there is no inline assembler, so I have to compile speex without arm-asm. But I still trying to find a way to use speex with arm-asm under my EVC++ application. I tried to compile speex with arm-asm under gcc (arm-wince-pe), but generated static link

How do I do Centos 7 p2v migration?
Hi, I am trying to figure out how to do p2v and v2v migrations on a Centos 7 kvm host. With previous versions there was virt-p2v but that does not seem to exist with Centos-7. I realize that if I am using shared storage, I can do live migrations but that does not help with p2v migrations. Does anyone know what the recommended procedure is for migrating either physical or virtual machines to
