DHCP client leaks hostname "amnesia"
_Originally created by @sajolida on [#7688 (Redmine)](https://public-redmine-archive.tails.boum.org/code/issues/7688)_
1\. Boot Tails 1.1.
2\. Install Wireshark.
3\. Monitor the network until a periodic
DHCP refresh is done.
4\. Click on the “DHCP Request” packet
going out to the local router/gateway/dhcp-server.
In the data in the packet one can see:
Bootstrap Protocol
Message type: Boot Request (1)
\[…\]
Option: (12) Host Name
Length: 7
Host Name: amnesia
\[…\]
In earlier Tails versions the hostname was not leaked, so this is a
regression.
