IPSec VPN Setup?
by Ski Dawg 10 Mar '10

10 Mar '10

Hello Everyone, I have been tasked at work with setting up a VPN connection from our server to a client's network. The only problem is that I have never done anything like this before, so I am not sure where to start. We are running CentOS 5.4 on our server. I do not yet know what the client is running for their VPN, the only thing I know of from the client, is we need to use IPSec for our VPN connection to them. I have been googling, and have found quite a bit of information, but it is a little overwhelming, as I am new to setting up a VPN. Is the a "standard" method for doing this sort of setup that I am missing so far? If anyone has any quick pointers to get me started, that would be greatly appreciated. -- Doug Registered Linux User #285548 (http://counter.li.org) ---------------------------------------- Never trust a computer you can't throw out a window. -- Steve Wozniak

Exim VS Postfix (no flame wars please)
by Rudi Ahlers 10 Mar '10

10 Mar '10

Can anyone, who has used both Postfix & Exim please share some experience with me? Which of these 2 did you prefer to use, and why? cPanel uses Exim (and AFAIK, only Exim), VirtualMin seems to use Postfix by default and often times when a custom server is installed a client doesn't know which to use so we recommend Exim. But, what are the differences between these 2, from your experience, if you don't mind telling me? I have used Qmail on FreeBSD 4.8 last and don't even consider this as a good mail system anymore, so I'm not even looking at it right now. -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Filter web content in a LAN ?
by Niki Kovacs 09 Mar '10

09 Mar '10

Hi, I installed a network of five desktops in a small town hall, all running CentOS 5.4. The machines are publicly, and the mayor asked me to find some solution to effectively filter web content, as the kids' first reflex is to visit the interesting bits of the Internet first, from satanism to porn. One of the machines will be set up as a router anyway, since the public computer room gets its internet access from the town hall, and I've decided to make another subnet for it. Any recommendations for that? Niki

proftpd wrap
by CList 09 Mar '10

09 Mar '10

Hi, My ftpd is being abused. Maximum login attempts exceeded from hosts: ::ffff:64.251.22.142[::ffff:64.251.22.142] : 24197 Time(s) I had came across an article stating that proftpd with mod wrap can actually block these IP using denyhosts. I had googled but I did not see any proftpd rpm with mod wrap. Is there anyone with a copy would like to share? Or can someone share a spec file, so I can roll my own rpm. I am running on CentOS 5.4. Thanks wL

LVM & Stripe
by Lincoln Zuljewic Silva 09 Mar '10

09 Mar '10

Hello list, I have a question about LVM. My server has five disks and I will use it to create a LVM environment. I saw in the lvcreate man page that I can use the “-i” option to set the number of disks that I want to stripe the lvols, but this option doesn’t exists in the “lvchange” option (in case I add new disks to the VG). I had in mind: create 10 lvols – “lvcreate -i5 -L 10G MyVG /dev/MyVG/lvol[1-10]” and in the future, add more disks and increate the stripe value of the existing lvols. Does anybody knows how to change the parameter “-i" of a lvol that already exists? Best Regards Lincoln Zuljewic Silva More contact info.: http://www.system.adm.br/contact.php "How often must a question be asked before it’s considered a frequently asked question?"
