I have if working now: Suse petition:
14:34:40.016808 IP (tos 0x0, ttl 64, id 30707, offset 0, flags [none], proto: UDP (17), length: 576) 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:0c:6e:89:e2:fb (oui Unknown), length: 548, xid:0x7db0417b, secs:10, flags: [none] Client Ethernet Address: 00:0c:6e:89:e2:fb (oui Unknown) Vendor-rfc1048: DHCP:REQUEST MSZ:548 RQ:172.25.51.90 LT:4294967295 PR:SM+DG+NS+HN+DN+RP+TTL+BR+MD+RD+SR+YD+YS+NTP+LPR+LOG+WNS +WDD+WNT+WSC HN:"linux^@" VC:"Linux 2.6.11.4-21.7-smp i686" CID:[ether]00:0c:6e:89:e2:fb Debian one: 16:35:07.279121 IP (tos 0x10, ttl 64, id 0, offset 0, flags [none], proto: UDP (17), length: 328) 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from 00:0c:6e:89:e2:fb (oui Unknown), length: 300, xid:0x63125d08, flags: [none] Client Ethernet Address: 00:0c:6e:89:e2:fb (oui Unknown) Vendor-rfc1048: DHCP:REQUEST RQ:172.25.51.201 PR:SM+BR+TZ+DG+DN+NS+HN+WNS+WSC The main difference was: CID:[ether]00:0c:6e:89:e2:fb And just putting send dhcp-client-identifier 1:YourHwAddres; on /etc/dhcp3/dhcpclient.conf resolve everything. So, Why RedHat, SuSE, Windows works properly with Cisco and not Debian? i don't have access to a RedHat or Suse until monday but i will took a look to know how they do it. Anyway, that field should not be used for this issues, so i will have a talk with our University Network Man to see how he has configured the switches. Thx in advanced for everything and sorry.
