IP Address grep doesnt always work

[ssimpson89]

Hey guys,

I have an openvz node and ip addr does not always show "state UP". I t will show an UNKNOWN even though network is going, so the command in the main.py fails and on top of it I dont think the awk statement works on all systems:

pydash]# ip addr | grep -A3 'state UP' | awk '{printf \"%s,\",$2}' |awk -F, '{print $1, $2, $3}'
awk: {printf \"%s,\",$2}
awk:         ^ backslash not last character on line

I normally use the following:

ifconfig  | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk '{ print $1}'

or

ip add | grep inet\\s | grep -v 127.0.0.1 | awk '{ print $2 }' | sed 's/\/[0-9]\{1,\}//' 

Just figured I would throw it out there.

What OS are you running on the node?

Btw if you run that command on the server manually you will need to remove the \ as those are needed inside python to escape the double quotes.

CentOS 6

Is that inside the OpenVZ container or main node?

This issue is from inside the openvz container

Thanks, can you provide me with the output of: ip -V , until i get to setup a openvz instance. I'm trying to find the best way of grabbing the ip details across OSs and iproute package is one available across all or most at this point.

Check out the latest version and open again if you still see the issue.
