freebsd stable - Nov 2018 - sudo not available after configuring ipmi serial over lan

Hi guys,

After configuring ipmi serial over lan console, I am not being able to
execute any command related to sudo; not even "sudo su -". I am using
ttyu0
and COM1 on a Dell R530. Everything regarding receiving output and typing
at the serial console is fine; the only command not working is sudo.

Any ideas? Below are the configurations.

/etc/ttys

# Serial terminals
# The 'dialup' keyword identifies dialin lines to login, fingerd etc.
#ttyu0  "/usr/libexec/getty 3wire"      vt100   onifconsole secure
ttyu0   "/usr/libexec/getty std.115200" vt100   on          secure
ttyu1   "/usr/libexec/getty 3wire"      vt100   onifconsole secure
ttyu2   "/usr/libexec/getty 3wire"      vt100   onifconsole secure
ttyu3   "/usr/libexec/getty 3wire"      vt100   onifconsole secure
# Dumb console
dcons   "/usr/libexec/getty std.9600"   vt100   off secure

/boot/loader.conf

# ipmi enabled
ipmi_load="YES"
# ipmi configurations
boot_multicons="YES"
boot_serial="YES"
# serial configurations for COM1
console="comconsole,vidconsole"
comconsole_speed="115200"
comconsole_port="0x3F8"
hint.uart.0.flags="0x00"
hint.uart.2.flags="0x10"

Use network access to perform the following:

1) Change "on" to "off" for ttyu0 then run "init
q" to apply changes.
2) Replace "ttyu0" with "cuau0" within same line then run
"init q" again.

Then retry using console and sudo.

What do you mean by 'not working'? Is there an error message? Does it  
hang? Do you get logged out?

try looking into a manpage of your choice, does this work?
We had similar problems here with IPMI/SOL, these could be fixed by
using a 3wire getty instead of std:

ttyu0   "/usr/libexec/getty 3wire.115200" vt100   on          secure
