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. This is the reason I am asking. I had the chance of finding the SoftEther Project which gives a lot in terms of VPN Client and Server. At: http://www.softether-download.com/en.aspx 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 have seen couple guides\tutorials on the internet: - https://raymii.org/s/tutorials/IPSEC_L2TP_vpn_on_CentOS_-_Red_Hat_Enterprise_Linux_or_Scientific_-_Linux_6.html -

The docs a re a bit weird on "Directory hashing"
In squid we use a double layer of hashed directories on the FS to allow 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.

Report on Xen-4.6rc2 from virt7-xen-46-candidate
Hey, What do you mean by doesn't do forking? It allows forking processes if the application can do that. It doesn't fork them by default but ,is it really needed? If xenstored is testing to be run under systemd and not forks itself because of it, that's another thing.

I want to connect to a l2tp server from centos.
OK So i took the time and finally built a RPM for the softether vpn server and client. I have not tested them for usage but I found out that only the server side can work with multiple protocols while the client side works only with one protocol. The actual protocol is called "ethernet overl HTTPS". More info on the product: http://www.softether.org/ The gui is only for windows as
