bad udp cksum
I have seen such and issue but it depends on the environment structure.
I have seen it mostly on VM's and it was resolved.
The hardware and software details of the setup might help to understand
what's causing it.

the script is:
require ["fileinto", "envelope"];

I want to connect to a l2tp server from centos.
Hey John,
I do not require encryption at all, it's a secure and internal channel
but it requires me to connect via either pptp or l2tp.

terms of VPN Client and Server.

But yet to try it.
Also they have all sorts of beta versions but not

I want to connect to a l2tp server from centos.
Hey Gordon,
I do not have any security issue in this network.
I need to connect to a remote network on a secure network.
The options are pptp or l2tp(no ipsec encryption) so I do want to use
l2tp like in (lac\lns) and I am looking for a client for CentOS.
Note that it works in ubuntu so it is possible to achieve the same with
CentOS but I do not know what is behind the gui that initiates the

I want to connect to a l2tp server from centos.
I have a server currently connecting to a pptp remote server.
This server(lns\lac) has the option for pptp connections and l2tp
connections.
The l2tp connections are not using ipsec encryption at all.

I want to ask about some Kernel level operations.
I want to make sure that while compiling as root nothing will break down
inside the machine.
I want to compile software on a Xeon SERVER.
The basic issue is that there is a recommendation to not compile it as a
root user.
I have compiled software as a root user more then once and I am not sure
why would there is a need to run it as non-root user?
I have taken a look at the /proc/ FS but I do

You could say the same thing about computers in general:
I hate them, they automated many tasks in life and took many jobs out of the

Hi.

Then I destroyed pool and put SVM stripe on top the same disks utilizing the fact that zfs already put EFI and s0 represents almost entire disk. The on top on

The docs a re a bit weird on "Directory hashing"

storage of millions of files.
I was reading the "Directory hashing" section but never understood it..
since it's written.. in a way I could not understand.

What FileSystems for large stores and very very large stores?
I was learning about the different FS exists.
I was working on systems that ReiserFS was the star but since there is
no longer support from the creator there are other consolidations to be
done.
I want to ask about couple FS options.
