I am trying to set up a static ip address on my network. And it did kind of work, but locked out my email which is Evolution, the web worked afterwards. TTrying to set static ip addresshis is on a LinuxMint 18.3 box. I need it to be static because it will be my samba server.

# interfaces(5) file used by ifup(8) and ifdowTrying to set static ip addressn(8)
auto lo
iface lo inet loopback
auto enp6s0
#iface enp6s0 inet static
#address 192.168.0.120
#netmask 255.255.255.0
#gateway 192.168.0.1
#dns-nameservers 208.67.222.222
#dns-nameservers 208.67.220.220
#dns-search itzgeek.local

I took this file and commented out the fourth line and uncommented the lines below that. So I translatesdtranslatesid a little research. Going back to previous state my settings are:

IP Address: 192.168.0.14
Netmask: 255.255.255.0
Gateway: 192.168.0.1
DNS: 192.168.0.1

My Internet Provider is Mediacom and I think the router updates the gateway and dns server addresses to the local computer. I tried setting the dns-nameservers to 192.168.0.1, but that did not work. Any suggestions?Trying to set static ip address

Evolution is set to Defer to Desktop Settings
Trying to set static ip address
Thanks in advance, Terry

My static configuration in /etc/sysconfig/network-scripts/ifcfg-enp3s0
Note the names for the variables. For example, it's IPADDR not "IP Address"
And it's VARIABLE=value, not VARIABLE: value

DNS is that of my ISP (Cox Communications)

No that did not seem to work, no IP Address even showed up. This is what I had:

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
#auto enp6s0
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
NAME=enp6s0
DEVICE=enp6s0
ONBOOT=yes
IPADDR=192.168.0.120
PREFIX=24
GATEWAY=192.168.0.1
DNS1= 208.67.222.222
DNS2= 208.67.220.220
DNS3=8.8.8.8
ZONE=public

Thoose two first dns addresses are what I am using on my old desktop, the one this is to replace. I believe it is OpenDNS.

/etc/network/interfaces configuration file is typically used by debian and its derivatives.

/etc/sysconfig/network-scripts/ifcfg-xxxx is typically used by Red Hat,SuSE and their derivatives.

They are not interchangeable and therefore what you posted will not work for the OP. I assume that Network Manager is running which if not disabled will conflict with trying to setup a static IP address via the interfaces file. You should be able to setup a static IP address using Network Manager as well as an address reservation in your router's DHCP server.

Noted. I'm only familiar with Red Hat and it's derivatives (I use CentOS). I apologize for confusing the OP. Yes, they should probably use Network Manager. I've always done network setup by editing the ifcfg-* files, so can't help there.

You make an excellent point about the router's dhcp setup, however. One cannot establish a static IP address if the address being used is within the router's dynamic range, which I would expect 192.168.0.14 to be, by default.

I need to work on my reading comprehension. . . .

Most SoHo router's that I've played with recently have x.x.x.100 as the start of the DHCP address range.
