Trying to make an IPSec IKEv2 connection with Google Cloud VPN services.
According to them, they support AES-CBC ciphers for Encyprtion at phase 1, but at the moment of negotiation with the on-premises VPN gateway only AES-GCM ciphers are offered.
So I get the famous "no proposal chosen" IKE SA error.
Do I need to tweak something on Google Cloud?
Having UDP messages sent from dynamic public IP periodically to public IP X:20000.
Need a proxy that listens in IP X:20000, then forwards duplicate/clone packets to X:20001 and a different machine located in IP Y:20000. Now, when application listening on X:20001, responds to a message to X:20001, I want that message to be forwarded back to PC A, from X:20000.
How could I achieve this functionality in Linux? (trying to avoid custom script)
Trying to have one application in a headless server responding to messages, and one computer with monitor to debug messages when needed in real time.
I'm a Cisco newbie, have the 1841, with two ethernet interfaces:
interface FastEthernet0/0: Internal
Desired destination IP: 186.67.181.140
interface FastEthernet0/1: External World
IP 186.67.181.140
Want to make a HTTP port forwarding from External World to Internal IP.
Tried adding this rule, but does not make the forwarding:
ip nat inside source static tcp 192.168.1.20 80 186.67.181.140 80 extendable
Any idea why I don't get the port forwarding right?
Complete configuration:
interface FastEthernet0/0
ip address 192.168.0.1 255.255.255.0 secondary
ip address 192.168.1.1 255.255.255.0
ip nat inside

interface FastEthernet0/1

Having 2 linux box with Nagios Core, I understand that one way of communicating them is using the NSCA plugin and install client plugin in one and server plugin in the other.
Maybe there is an easier way like slave/master configuration, without using NSCA plugin.
Can you describe possible ways of achiving this?
Real situation is that we have 1 host that uses GPRS, so it's IP is dynamic so we need to send monitoring information to a static IP Nagios server.
Having these two rules works good:
ProxyPass / http://localhost:8080/app
ProxyPassReverse / http://localhost:8080/app
When client visits, domain.com, Apache calls app server and it works as expected.
Problem is that there is one directory, generated by the app server that I don't want to be prepended with /app.
For example:
domain.com/app/styles/file.css (actual case)
domain.com/styles/files.css (this is how I want this)
Any ideas?

Nevertheless Windows PC can't discover this server, but server actually responds pings.
Any idea why I can't reach the Linux Server?
Trying to access X11 my CentOS 6 x32 small Linode VPS through SSH Putty/Xming (enabled X11 forwarding on options).
My windows machine is not the problem since it works with others CentOS Servers.
X11Forwarding is enabled on /etc/ssh/sshd_config, still I can't get X11 forwarding.
I'm trying to get xclock to work, but I get Can't open display :0.0 error.
I've also tried with different $DISPLAY values like :0 or :10.0
I've tried MobaXterm, and I get this message when connecting:
X11 forwarding request failed on channel 0
Having problems installing Java EE 6 in CentOS 6 x32.
I have removed all previous version of Java and freshly installed temporally jdk1.6.0_34.
So my $PATH variable goes to:
/usr/lib/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/opt/jdk1.6.0_34/bin/
Everything seems good to run:
[root@localhost opt]# ./java_ee_sdk-6u4-jdk7-linux.sh
but it spits the following errors:
