fingerprint Debian/linux Jessie

carlos_alarcon — Mon, 29 Aug 2016 16:00:53 GMT

Which string do Ruckus ZD expect on DHCP option-60 to be identified as Debian Linux Jessie?
I had tried plenty of them and always get N/A as OS type
Any way to customize it so we can identify custom linux distributions?
We are using Ruckus R500 Aps

If you have a "Debian Linux", could you provide a trace to Tech Support?

Sorry if I do not now what do you mean with a trace (perhaps a trace from AP, which I do not know how to get) but I can provide you the tcpdump capture from the DHCP server side: https://dl.dropboxusercontent.com/u/44025498/dhcp_debian_linux.pcap

This is the DCHP trafic from DHCP server
I achieve that by setting client dhclient.conf with:

option rfc3442-classless-static-routes code 121 = array of unsigned integer 8;
send vendor-class-identifier "Debian Linux";
request subnet-mask, broadcast-address, time-offset, routers,
	domain-name, domain-name-servers, domain-search, host-name,
	netbios-name-servers, netbios-scope, interface-mtu,
	rfc3442-classless-static-routes, ntp-servers, root-path;
require root-path, routers, subnet-mask, domain-name-servers;

And of course by setting up dhcp server (dnsmasq in this case)

I managed (sorry I am not the one managing APs and ZD, he is on holidays, and I am not used to to handle with them) to get some logs from the AP: https://dl.dropboxusercontent.com/u/44025498/SupportLog_2C-C5-D3-02-AE-40.log hope this help

Please open a ticket to explore and might help determine your Linux flavor DHCP option details.
