CentOS Virtualized – eth0 not found?

By polfilm,

Network interface probably changed the name when you cloned as original version guid and mac are stored in a different file. To verify run:

ifconfig -a

or

ip a l

If its hiding under eth1 or some other name then you’re in luck.
Remove the kernel’s networking interface rules file so that it can be regenerated

rm -f /etc/udev/rules.d/70-persistant-net.rules

Now set your eth0 info in /etc/sysconfig/network-scripts/ifcfg-eth0. Remove mac and guid from the file and reboot. For static IP setup you may want to try this

EC2 Demo of MCollective – Puppet Labs

By polfilm,

The Marionette Collective AKA MCollective is a framework to build server orchestration or parallel job execution systems.

We’ve attempted to think out of the box a bit designing this system by not relying on central inventories and tools like SSH, we’re not simply a fancy SSH “for loop.” MCollective use modern tools like Publish Subscribe Middleware and modern philosophies like real time discovery of network resources using meta data and not hostnames. Delivering a very scalable and very fast parallel execution environment.

Static IP Address OpenSolaris 134

By polfilm,

Modify /etc/nwam/llp

iface static 192.168.10.100/24

Update DNS server in /etc/resolv.conf

Copy in /etc/ and restart DNS client

cp nsswitch.conf nsswitch.conf.original
cp nsswitch.dns nsswitch.conf
svcadm restart svc:/network/dns/client:default

Restart nwam

svcadm restart svc:/network/physical:nwam

Modify route to gateway in /etc/defaultrouter (single IP will do)
Restart routing

pfexec svcadm restart network/routing-setup

Static IP Address Fedora 17

By polfilm,

load file to edit

$ nano /etc/sysconfig/network-scripts/ifcfg-eth0

edit

DEVICE=eth0
BOOTPROTO=static
IPADDR=10.10.10.150
NETMASK=255.255.255.0
GATEWAY=10.10.10.1
DNS1=8.8.8.8
DNS2=8.8.4.4
ONBOOT=yes
NM_CONTROLLED=no

restart

$ sudo /etc/init.d/network restart

Disable Network Manager, Enable Network Service

# systemctl stop NetworkManager.service
# systemctl disable NetworkManager.service

Then you enable the network service in a similar fashion.

# systemctl enable network.service
# systemctl start network.service

Don’t forget to set host resolve  /etc/hosts and hostname /etc/sysconfig/network [HOSTNAME=]
