Bug#635604: dnet-common: package causes ethernet address to be set to aa:00:04:00:0a:04
Leaving aside the dependancy bug (which is not dnet-common's issue at all) - there's three distinct problems here, both of which definitely are :- 1/ The MAC address assigned in the default case is not unique (imagine the effect of a stock-with-defaults install of this package on a 1000-way compute cluster!) 2/ Burned-in-addresses are, for better or worse, increasingly being incorporated into link-layer authentication/ authorization schemes (and even, in certain cases, even encryption schemes) - particularly in the wireless space 3/ 802.1d uses address uniqueness to decide which bridge-port a given host is reachable-via (a certain hilarity will result if two stock-with-defaults install of this package are connected to networks either side of a learning-capable bridge - such as those commonly found in EVERY modern Ethernet switch fabric) Please - dnet-common needs to default to not changing anything at all (ie, please DON'T default to safety-off when handling shotguns loaded with live ammunition and aimed at feet); and if and/ or when it does - the default should not be static assignment (ie, the _whole world_ defaulting to the same DECNet address) but rather introduce at least some kind of fuzz (ie to reduce the probability of collisions within a given broadcast domain).
Bug#635604: dnet-common: package causes ethernet address to be set to aa:00:04:00:0a:04
Package: dnet-common Version: 2.56 Severity: critical Justification: breaks unrelated software when libroarcompat1 is installed, dnet-common is a recommended package brought in with libdnet when apt/aptitude is configured to bring in recommended packages. This caused the ethernet hardware address to be set to aa:00:04:00:0a:04, causing DHCP and telnet to fail, and also caused problems on one machine using ftp. A clear demonstration of the problem would be to run: # ifconfig eth0 which would show the new aa:00:04:00:0a:04 ethernet address, and then to run: # ifdown eth0 followed by # ifup eth0 If the DHCP server is only expecting the actual ethernet card's hardware address, the machine running dnet-common will fail to get an IP address. If the DHCP server issues IP addresses regardless of ethernet hardware addresses, the machine running dnet-common may a different IP address from when it started up, as the hardware address supplied by the machine is now different. -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 3.0.0 (SMP w/4 CPU cores) Locale: LANG=en_AU.UTF-8, LC_CTYPE=en_AU.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of unsubscribe.
