Solaris, Serial Consoles, Cisco Firewalls and TFTP

Using a serial console + tftp server on Solaris:

% screen /dev/term/b 9600

or

% cu -s 9600 -l /dev/term/b

or

% tip hardwire

Where you have hardwire defined in /etc/remote:

hardwire:\
:dv=/dev/term/b:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:

Configuring a TFTPD server in Solaris 10:

# mkdir /tftpboot
# echo "tftp dgram udp6 wait root /usr/sbin/in.tftpd in.tftpd -s /tftpboot" > /etc/inetd.conf
# /usr/sbin/inetconv
# svcs network/tftp/udp6
# svcadm restart network/tftp/udp6

Now we can dump some new images in the ftpdir, and upgrade our firewall :-).
