NimbostratusUsing PyControl for LTMs v9.4.8 through 11.2
So I am new to Python and IControl. I have built a python script that will take a list of hostnames and make sure they are reachable. This is a text file with the following format:
hostname1.mydomain.com
hostname2.mydomain.com
hostname3.mydomain.com
It runs fine, but now I want to log into the devices and find out what version of code they are running. I don't know how to have python be able to tell when it logs in if the Load Balancer is running version 9.4.8 or 10.2.4 or 11.2 as we have all three in our enivornment. I was trying to avoid having to write a script for each device type as that would be a management nightmare.
I have instally PyControl 2 and also BigSuds in my environment.
So basically the flow would be
Open File with LTM Hostnames
Read a line
Log into that host and find out the OS version
Pass the value to another text file
Rinse and Repeat for each line in the File
Close the File
Print out the newly created File
Since version 11.x doesn't support bpshell and v9.x doesn't support tmsh, I am not sure how to work this out.
Any advice, guidance or examples would be greatly appreciated
Thanks

Wally_Steadman_I got it figured out after some reading. I see that IControl handles the different device types already so I am not able to get a list of hostnames and version of code.
Indrek_38497Hello,
For getting version of BIG-IP software can be used next code:
!/usr/bin/python
def get_version(obj):
try:
return obj.LocalLB.VirtualServer.get_version()
except Exception, e:
print e
if __name__ == "__main__":
import bigsuds
import getpass
f = open('./devices_list.txt', 'rU')
o = open('./versions_list.txt', 'w')
for list in f:
b = bigsuds.BIGIP(
hostname = list.rstrip(),
username = "username",
password = "password",)
fstr = "Device %s is running version %s\n" % (list.rstrip(), get_version(b))
o.write(fstr)
print fstr.rstrip()
f.close()
o.close()Regards,
Indrek
