I worked as the Product Support Expert for the Linux/Unix agent for a while, and there are good number of customers. We have customers who use them as Point of Sale (POS) devices, and customers who use them as desktops, and customers who use them as servers...so a wide variety.
Hopefully some of them speak out here. If not, have your Sales Engineer find a customer who is uses Linux and will talk to you.
We use LANDesk agent on around 400 Linux servers, mainly RHEL4 32b & RHEL5 64b.
At the moment we use it for inventory purpose & to launch scripts on all servers. We intend to go for OS Deployment.
The main issue we have is that our machine are quite heterogenous as a configuration so we got a lot of issues. Also, Linux is not as known as windows environment within the support or community and our case / request may be very long to be solved...
Sanitized to protect the server names......
# Landesk Linux desktop inventory script
# Exit out if the script is not being run by superuser
if [ $UID != 0 ]
then echo "This script must be run by root"
#grab a fresh copy of linuxscan script and put in /tmp
chmod +x linuxscan.sh
#add cron job for weekly scans at 10pm on Mondays
cat > /etc/cron.d/landesk << EOF
