Hi,

I have been using Skype for a while and wanting to find an open source
alternative.
Skype uses encryption which most of the open source counterparts lack.
Also, with skype it's not a direct connection between the two PCs, I think
they use nodes/super nodes or something similar in the middle.

I know Ekiga can be used to call directly with h323 protocol but it lacks
native encryption, to make it secure I will have to either use ZRTP or have
VPN set up.

Is there a simpler alternative that allows for direct IP to IP voice
communication and is secure?

I am using the below command/s to write to 3TB hitachi deskstar 7200RPM
disks.

dcfldd if=/dev/urandom status=off | PV -s 3000G | dcfldd of=/dev/sda
of=/dev/sda of=/dev/sdb status=off bs=4096

on the HP microserver nl40 with SATA 3Gbps connection, the throughput was
3-4MB/s, around 10.5 days.
Where as on my desktop with i5 CPU and 6Gbps connection, the throughput is
13-14MB/s, around 61 hours.

My question is: where is the bottleneck on the HP for such low throughput?

dcfldd uses one core, granted my desktop is around 4Ghz and HP just under
2Ghz. But....
So far I have heard lot of people say the SATA connection should not make
any difference to the throughput on a spindle HDD.

Anyone know the reason for such low throughput on HP?

Hi all,

I am building a new freebsd fileserver to use for backups, will be using 2
disk raid mirroring in a HP microserver n40l.
I have gone through some of the documentation and would like to know what
file systems to choose.

According to the docs, ufs is suggested for the system partitions but
someone on the freebsd irc channel suggested using zfs for the rootfs as
well

Are there any disadvantages of using zfs for the whole system rather than
going with ufs for the system files and zfs for the user data?
