Correct, which is why I referenced the "host" command in my earlier note. Ultimately, host is doing a DNS lookup. If the DNS lookup fails, the script stops its execution because failing that check means that it can't guarantee that the rest of the script will work correctly.

As with many things Mac-related, check your DNS.

Sounds like a curl issue and that you're trying to download from a web server via HTTPS.

The curl command in the script doesn't do certificate validation, so I'm betting it's a timeout issue unless you've changed the curl function as written in the script.

yea web server is https

from rtrouton_scripts.

I'd recommend a couple of things:

1. Tracking down what that error message actually means.
2. Getting HTTPS out of the loop and testing against an HTTP server. If the script works when downloading the .zip file from HTTP, the problem is outside the scope of the script.

placed the file in a http download location now getting this

Do you have the fully qualified domain name of your JSS listed in the following variable?:

jss_server_address="server_name_here.domain.com"

It should not be this: jss_server_address="http://server_name_here.domain.com"

If you do not have "http://" in the "jss_server_address" variable, it may be a DNS lookup issue. That error is triggered by the "host" command trying to do a DNS lookup of the server address defined in the "jss_server_address" variable and the lookup not succeeding.

I have just jss_server_address="server_name_here.domain.com" but we do use public ips for most of our workstations not sure if that's an issue.

from rtrouton_scripts.

Can you ping the JSS from the affected Mac, using the DNS address that you've put into the "jss_server_address" variable?

from rtrouton_scripts.

yes

You may want to increase the sleep amount listed in line 367:

sleep 120

Try setting it to:

sleep 240

Your DNS may not be coming online in two minutes. See if increasing it to four minutes fixes the issue.

my issue seem to be coming from:

CheckSiteNetwork function adapted from Facebook's check_corp function script.

check_corp script available on Facebook's IT-CPE Github repo:

check_corp:

This script verifies a system is on the corporate network.

Input: CORP_URL= set this to a hostname on your corp network

Optional ($1) contains a parameter that is used for testing.

Output: Returns a check_corp variable that will return "True" if on

corp network, "False" otherwise.

If a parameter is passed ($1), the check_corp variable will return it

This is useful for testing scripts where you want to force check_corp

to be either "True" or "False"

USAGE:

check_corp # No parameter passed

check_corp "True" # Parameter of "True" is passed and returned

site_network="False"
ping=host -W .5 $jss_server_address

If the ping fails - site_network="False"

[[ $? -eq 0 ]] && site_network="True"

Check if we are using a test

[[ -n "$1" ]] && site_network="$1"

Got it working :-)

Great! Glad to hear it.

I change the DNS server in /etc/resolv.conf for my Mac. Where can I modify the DNS server in the windows system?
