hi there im triing since ages to get my Client ID like shown below:

"AVM dhcpdiscover 1.0 dslforum.org"

this string is requierd for my ISP

but unfortunately udhcpc always just takes the first word:

    Padding: 000000000000000000000000000000000000000000000000...

i tried with '' quotes with "" quotes without luck...

does anyone know how i can get a string with 'spaces' in there?

thanks in advance for your help

i already tried the idea below:

%20 or +?

Unique Client ID (option 61) or Vendor class (option 60)????

You write about "client id", but your example shows Vendor class as AVM, so I guess you are actually talking about the Vendor class option...

If so, you might try this recent patch for /lib/netifd/proto/dhcp.sh that patched LEDE master to accept vendor IDs with spaces:

    Option: (255) End
        Option End: 255

there we go! thanks for the hint

solution was:
+        ${hostname:+-H "$hostname"} \
+        ${vendorid:+-V "$vendorid"} \

in the  /lib/netifd/proto/dhcp.sh
