My work needs to clone some Thin Clients and they use Ubuntu as base to the VMware Client, but the problem is we have to edit manually the line in the /etc/vmware/view-mandatory-config with the MAC of the Hardware.

view.sslVerificationMode = "3"
view.defaultUser = "CM-d4_85_64_71_58_44"
view.autoConnectDesktop = "TRUE"
view.autoConnectBroker = "TRUE"
view.kioskLogin = "TRUE"
view.nonInteractive = "TRUE"
view.fullScreen = "TRUE"
view.nomenubar = "TRUE"
view.defaultBroker = "viewcs"

We need to create a script that run automatically at boot (1 time and delete it self) and get the MAC of eth0 and past it like in the config file above.

view.defaultUser = "CM-d4_85_64_71_58_44"

We need this so we can save a lot of time.

---EDIT--- With what was answered I did the following script, still incomplete but Is working.

MAC=$(ifconfig eth0 | grep -o -E '([[:xdigit:]]{1,2}:){5}[[:xdigit:]]{1,2}')
echo "
view.sslVerificationMode = *3*
view.autoConnectDesktop = *TRUE*
view.autoConnectBroker = *TRUE*
view.kioskLogin = *TRUE*
view.nonInteractive = *TRUE*
view.fullScreen = *TRUE*
view.nomenubar = *TRUE*
view.defaultBroker = *viewcs*
view.defaultUser = *CM-${MAC//:/_}*
" > /etc/vmware/view-mandatory-config;
sed -i 's/*/"/g' /etc/vmware/view-mandatory-config

Is incomplete because, I don't know how to print (") in the file so I've used * and after I used "sed" to change * to ("), it's working like a charm.

I don't know why but I was not able to make this script run in boot.

First, I set it into /etc/rc.local and it did not ran. Second, I tried to put it in crontab as @reboot /etc/vmware/MAC.sh, and it not worked.

Thanks for your help.

    ifconfig eth0 | grep -o -E '([[:xdigit:]]{1,2}:){5}[[:xdigit:]]{1,2}' will get MAC address. (From stackoverflow.com/questions/245916/…) I am not good at shell scripting, still learning, but maybe someone can help bring this into text file

This should give you the string you want.

MAC=$(ifconfig eth0 | grep -o -E '([[:xdigit:]]{1,2}:){5}[[:xdigit:]]{1,2}'); echo "CM-${MAC//:/_}";

Replace eth0 with whatever the interface is. Output:

CM-d4_85_64_71_58_44

The grep code came from here:

  • When I ran the script I got a error: ./MAC.sh: 2: ./MAC.sh: Bad substitution, if I use a the following part direct on terminal I got the mac in my screen. $(ifconfig eth0 | grep -o -E '([[:xdigit:]]{1,2}:){5}[[:xdigit:]]{1,2}')

    Can you post how you put it in the MAC.sh script?

    I started it with #!/bin/sh, but I read in another question that I have to use #!/bin/bash, and it worked, I will edit my top post with more information.
