Starting Nov 29 04:16:10 I start seeing a new error in my /v/l/messages from dhclient (the DHCP client for my Shaw internet connection):
Nov 29 04:16:10 pog dhclient[1271]: parse_option_buffer: malformed option dhcp.fqdn (code 81): option length exceeds option buffer length.
And it repeats every 30-39s for hours, then sometimes stops for a while. Sometimes skips a day but then starts up again.
Is someone trying a known DHCP buffer overflow attack on my Shaw segment or is this something legit that Shaw is passing out that linux doesn't understand? I know what fqdn means, though why it should exceed buffer limits is beyond me.
Can others check their logs and see if they're getting this too?
There was 1 other weird dhclient error before this started: Nov 27 06:52:55 pog dhclient[1271]: parse_option_buffer: malformed option dhcp.uap-servers (code 98): option length exceeds option buffer length.
