OpenVPN throughput
Hello listmates, We are working on setting up two private networks linked by a public network which is fast (1 Gbit/s) but potentially insecure. Since the hosts on our two networks need to talk to each other, and do so securely, we have decided to use OpenVPN to connect them, making one gateway a server and the other a client. The connectivity part was easy to establish and worked like a charm.

Max hard disks supported by XCP 1.6
Hello, I would like to use nas4free under xcp 1.6. I install it under full HVM using "other install media". Now I am attaching 4 hdds as external disks. The vm sees at most two hdds, I suppose because of bios support (1 boot + 1 cdrom + 2 hdds= 4 hdds). I need to use more disks, is it possible? If not, it seems to me a serious limit. Mario

NFS vs SMb vs iSCSI for remote backup mounts
Hi, I would like to get some input from people who have used these options for mounting a remote server to a local server. Basically, I need to replicate / backup data from one server to another, but over the internet (i.e. insecure channels) Currently we have been mounting an SMB share over SSH, but it's got it's own set of problems. And I don't know if this is optimal, or if I

The moving of VNC port from 580n to 590n
On my 'older' systems that include Centos 5.5 and Fedora 12, vncserver is running on ports 580n where n is defined by userid in the /etc/sysconfig/vncserver I just spent a bit of time getting it working on my new Centos 6.3 server and found it listening on ports 590n. When did the change occur? And guess I should test out where it is on Fedora 17...

Certificate system
Hi all, Can anybody inform me wether the "RedHat Certificate System" or actually a CentOS equivalent is available for CentOS. Just skimmed on a download site through the RPM's for 5.3 and I couldn't find it. According to their pressrelease, it the code should be gpl, allthough I can't find any rpm for RH, FC or Centos.

protecting multiuser systems from bruteforce ssh attacks
Hello, What is the best way to protect multiuser systems from brute force attacks? I am setting up a relatively loose DenyHosts policy, but I like the idea of locking an account for a time if too many attempts are made, but to balance this with keeping the user from making a helpdesk call. What are some policies/techniques that have worked for this list with minimal hassle? Thanks! -Eugene
