System logs are stored under
/var/logs on the installer media (a
tmpfs(4) mounted file system).
The developer is most likely interested in
/var/log/messages, if it's not that log, ask him which log he wants. Perhaps he wants also the wifi devices technical specifications, best is to ask.
If an internet connection can be configured via Ethernet (or if you have a smartphone), you do not necessarily need to save the file on the startup device. In this case send the content of the file to a text storage site.
To configure a Ethernet connection, use
bsdconfig(8), "Networking Management", "Network Interfaces".
To use the phones USB tethering function to connect to the internet, plug in the phone to the FreeBSD machine, activate USB tethering (this will create a ue0 device node), request a IP (
dhclient ue0).
Send text:
Code:
cat /var/log/messages | nc termbin.com 9999
This will display a URL from which the content can be retrieved.
If you want to save the log on the USB drive ("disk/flash drive"), easiest is to install the system on a second USB drive.
If that's not an option, boot the installer media in single-user mode, mount the file system read-write (
mount -u /), remove in
/etc/fstab the "ro" option from the root file system.
Ctrl+D to enter multi-user mode, create a directory and copy
/var/log/messages.
If the developer is asking for a kernel panic dump, this requires to configure a dump device.
