i use redhat 8.0 (kernel 2.4.20-13.8) with iproute2-2.4.7-now-ss020116.try and tcng-9e i patched iproute2 and tc with the htb3.6-020525-patch from http://luxik.cdi.cz/~devik/qos/htb/ everything is working fine apart from the annoying error message: dsmark_dequeu: unsupported protocol 2054 i read in the artchive http://mailman.ds9a.nl/pipermail/lartc/2002q3/004855.html that this derives from ARP. in my tcng-config there is a line: /* Best Effort */ class (<$be>,mask 0, value 0x00) if 1; is this the reason for the error message because dsmark tries to remark the ARP-packet? how can i avoid this? regards martin
