Recently I upgraded a server from Fedora 21 to Fedora 23. This was a
difficult process because newer kernels (> 3.14.23-100.fc19) won’t work
with the system.
Finally I was able to boot the system with the old kernel, but I was not
seeing any information in /var/log/maillog.
Sendmail was running and I was able to send and receive messages, but
nothing was written to the maillog.
When I talked to somebody in #fedora he mentioned I could do a test by
running the following simple command:
I still have an old 486SX25 system which I use to run multiple ssh
sessions to different other systems. For instance to use IRC or view
email. This way I can keep track of those things when doing things in
fullscreen on my main desktop.
The system started showing the following error on every virtual console:
eth0: mismatched read page pointers 4c vs ff
After a time I saw the connections to other systems fail.
I used my servers’ IPMI (Intelligent Platform Management Interface)/BMC
(Baseboard Management Controller) connection to connect the
FreeNAS-9.3-CURRENT-201503130047.iso to the console and booted the
system via the CDROM interface.
After the iso has booted, it displays a grub menu to boot the FreeNAS
installation. When you do nothing this option is chosen by default.
