I am already a little bit familiar with Linux distros like Debian or Ubuntu (yeah, very similar) but I wanted to try Red Hat based – CentOS 6.2. I have installed it on my Windows 7 host in VirtualBox and tried to play with it a little.
Could someone explain to me what a socket is? I see it in many acronyms in context of SSL, etc.
NOTE: If client devices (computer B in this example) want to obtain
internet through the gateway computer, maybe they still need to configure
nameserver resolution. This is not explained here (a gateway does not necessarily serve internet).
I need to allow a user (different from root) to run a server listening on port 80.
I have rather an odd issue. I have a server with two network interfaces eth0 and eth1. Each are connected to a different network. Each network has a internet gateway. The server has various outbound connections: http (some scripts on the server scrape websites), nfs client, samba client, dns client and an email fetcher to name but a few.
I’m trying to set up a system that joins an untagged Ethernet network to a TAP tunnel, adding a VLAN tag as the traffic moves to the tunnel.
I have a process which listen to 2 ports : 45136/tcp and 37208/udp (actually I assume it is the same process). But netstat doesn’t return any pid :
NIC device handles
I am setting up a VMWare cluster of CentOS nodes. Is it best practice to include a domain name after the machine? What are the potential problems of leaving it out? Does a domain complicate configuration or simplify it?
