Networking :: Good Tutorial In Order To Learn IPSec Vpn With System?
Dec 17, 2010
I've no experience with IPSec. I've used many times OpenVPN (with static key or certificates x509).
Could anyone suggest me a good tutorial in order to learn IPSec vpn with Linux?
I have recently loaded Linux Mint on an old IBM Laptop and am very happy with the GUI; however, I would like to learn how to use the Linux shell/terminal. I don't know any of the commands. Is there a good online source for this information--a tutorial or list?
Does anyone knows about some good c++ tutorial ? I don't wanna something for absolute beginners,I need something for advanced topics, tips...Something you liked and helped you a lot I prefer Internet tutorials/e-books but "real" book should be good too.
I've been playing around a bit with Xlib programming, and I'm just wondering if anyone knows of a good tutorial involving XContext's? Even if someone could explain the concept to me a bit.
What would be a good book/manual to read to learn more about linux o.p. systems? and how to use them.I have to add I may not have such a good internet connection I might end up with free dial up (Bummer)so I'm not sure if a link will do.I will end up at the library anyway. so if you could suggest something that would be good, I'm not really looking for the history but more like how to use, maybe the terminal and such?.
I'm trying to Use Expect to automate a curl function. basically I don't want to type enter for my script to run. Can anyone point me to a good Expect tutorial?
Anyone know a manual to tell me the many things about Fedora? Like what is usr or a bin or a lib... Stuff like that I have a month to kill and I want to become an expert on this OS.
I wish to download a free version of Linux x86 (Debian, Mandriva, Red Hat or Ubuntu) so that I can install it and learn linux. The reason why I have mention the above versions is that I need to Install Oracle 10G on it to learn Oracle on Linux x86.
Can someone please post me the webiste url/s that I can download a free version of linux to learn?
I've been learning linux for a while now with half an eye on making a career out of it in future. One sizeable gap in my knowledge at the moment is networking. Is it feasible/desirable to set up a network of virtual machines to use as an environment to learn networking? My budget is non-existent so I was hoping to be able to get a basic understanding of the principles from installing a few desktops, a virtual gateway etc on VMware workstation on my laptop, and doing a lot of reading online.
Is this feasible, or will I just end up learning about virtual networks instead of real ones? Also how much power would be required, because my 3GB RAM lappy has just gone bang and all I have now is a (new) 1GB RAM lappy.
I have an IPsec VPN between 2 Ubuntu 10.04.1 Boxes which is working perfectly. However I cannot get any traffic to route down the VPN link.Interestingly, when checking the routing table, there isn't even a route list for the remote network. This is the same on both sides. Also there isn't an ipsec0 interface listed either.However, when a the command "sudo service ipsec status" is ran, it definately shows the tunnel is up and connected.
I install openswan on rhel6 and when i execute the command "service ipsec start "
it say: /usr/libexec/ipsec/addconn Non-fips mode set in /proc/sys/crypto/fips_enabled /usr/libexec/ipsec/addconn Non-fips mode set in /proc/sys/crypto/fips_enabled ipsec_setup: Openswan IPsec apparently already active, start aborted
I'm trying to perform a VPN lan to lan IPSEC connection. By my side, I have a server with 2 IP's, i.j.k.l (destined to act as a VPN gateway) and i.j.k.m (the server). I am a newbie. I don't know if this configuration is normal, but it's forced by our partner.
I've been using IPv6 on my local network and through a Hurricane Electric IPv6 tunnel. I've heard that one of the built in features of IPv6 is encryption, both scrambling the data and authenticating where the traffic came from. I've done some searching and heard of SWAN and Racoon, but some of the stuff I found is old and I would like to know what the easiest/best way to set up IPSEC for IPv6 is.
I had configured IPSEC/L2Tp on my Centos 5.4 gateway machine .For testing i had disabled firewall and Ipsec is working fine.I am able to connect from client etc...Now i want to allow Ipsec and l2tp throught Firewall.here is my Current Working Firewall.Only Openvpn is allowed and is Redirected.
eth0=XXXSTATICIPXXX eth1=192.168.1.81 OpenVpn IP Range = 172.24.0.16/4 Ipsec Ip Range = 192.168.1.0/24
i would like to establish a VPN connection which can hold either 'two' hosts..and secondly if that's done i would like to go for more number of users..Can i do it using IPSec services??if yes then how?
While I successfully configured an IPsec-VPN (I use a similar tho modified setup like this:[URL].. I am now stuck on the next steps. While I can connect to everything I want, I need to configure "access-groups" and/or "users".
The scenario is similar to this: Lets say Host A, B and C allow SSH-Connections and some weird non-standard UDP-Connection from Host-VPN, and are also accessible on other ports with public IP's (like http).
I now want to limit, that an admin-user has access to all of them, while trainee-admin only can access everything on Host B and C, and CEO only can connect via telnet to Host C - and all users can be roadwarriors
(I made this example up to give you an idea what i'm trying to do - hope it makes sense). Now my question is, if someone can point me towards a direction, as I'm quite clueless at the current moment as to what to try. I know that commercial IPsec-Implementations can do this, but can OpenSWAN/... give me something similar?
I have a Ubuntu 10.10 box which i've developed an IPTables Firewall script and is forwarding my ports correctly. This service also runs Openswan VPN Server with 2 VPN's, which is also working well.
I have come across a small snag with excluding the multiple VPN subnets I have from the NAT on this box.
Which when added to IPTables does make the VPN come to life. But I can't seem to get it to add the second subnet. Unfortunately, I can't do a blanket exclusion such as 192.168.0.0/16 because the second VPN is on a Class B subnet address which I cannot change.
Connecting two networks with ipsec on this manual [URL] The two networks are connected, everything works, the question is as follows: For a gateway to multiple subnets, I have access to only one subnet is listed in / etc/sysconfig/network-scripts/ifcfg-ipsec0 DSTNET = 192.168.2.0/24. How do I get access to all the subnets?
i need to build an ipsec vpn between a linux debian server and a zyxel prestige, The debian server got 2 ethernets connection one for the internal network and the other one is public with a public ip adress.I need to know what i need for the build the tunnel, could you please let me know what i need? Let me explain i have only to configure openswan or i have to configure the iptables or somethings else too? I found this one do you think this would be work for me? [URL]..Is debian a right distro or should i try someone else?
I've searched through google, and all I can find are instructions on how to set up a L2TP/IPSec VPN that works with macs and iPhones. I'm NOT trying to set up an L2TP/IPSec VPN. I'm trying to set up a pure-ipsec vpn.
The iPhone IPSec client is a built-in cisco client, I believe. I'm staying away from L2TP and PPTP because I need multicast packets to go through. *edit: wow, i just noticed that the title says "8.10 LTS". Oops! I obviously mean "8.04 LTS". Gah, the lack of sleep got to me.
