Are you sure the netmask and gateway are correct?

<div>
OK. I have a clue....<br />
<br />
When I set it up for 74.95.153.44, it fails. If I change to 74.95.153.43, it succeeds (i can ping google).<br />
<br />
My static IP range is 74.95.153.41-45 (usable).<br />
<br />
Any thoughts?

What about firewall - on your machine and on gateway?

You could post some more status.<br />
<br />
ip route show<br />
ip link show<br />
ip addr show<br />
<br />
and maybe<br />
cat /etc/resolv.conf

It wasn't so much a duplicate IP as an old firewall rule in our firewall. It used to be that there was a 1:1 NAT that forwarded to an internal address. The red interface was configured for multiple addresses, but later, the .44 address was removed from the interface, but the 1:1NAT rule was still in there. Deleted that, rebooted the firewall and all is well.

For some reason, I cannot get my static IP to work right. I had it working before, so I know the ip is good. If I turn on DHCP I get an IP and can get on the internet, so I know the hardware is good. Does anyone see what I am doing wrong with this config?<br />

What's wrong with my ifconfig?

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).

Linux Distributions

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.
