Today's power outage seems to have left my net 44 link DOA... If so I wanted
everyone to know I may be back.. No time to fix right now.. Just spent over
a week getting everything working after a virus attack. And was not really
done still had two systems down.. Now I have this.. I need a break, also..
May pick this back up in July... May not.
Anyone linked to me I will be back eventually.. Maybe Maybe not.
But now I have to figure out a few things.
Why does my Pi lose all its free space within 30 minutes of boot up. Went
from 73% to 100% cannot connect to it without rebooting over and over...
So until I feel like being a slave to linux and the PI I am off line.

I’ve seen this with logging. Something verbose fills the SD card (not good on the life of
the SD card either).

Probably would not have been so bad but the Power Co decided to cycle the power 7 times
before leaving it off... Looking this morning.. I have no clue what to do.. If you
remember let me know..

Bring your Pi up in 'single user mode' (look up 'single user mode' for
the Pi operating system that you are using) so that you can look at the
files without it being overwhelmed with more issues, you won't have
networking enabled.
Which directories on the Pi are getting filled up?
'du' is the command to use.
Start with:
du -sk /* | sort in
and then look at the largest directory (will be at the end) using the
same command, so that if /var is biggest:
cd var
du -sk * | sort -n
and keep going, looking at the biggest directory until the numbers get
smaller.
One possibility is /var/log, if this is the biggest, look into the
biggest file that you find. I will probably be over-full of messages
talking about a particular problem.
I've cleaned up after root attacks - it means *STARTING FROM SCRATCH* -
really, you absolutely must do this! and make sure to lock down your
system with the latest updates before connecting it to the Internet
again. I used a clean, separate computer to download what I needed.
And then, understanding that this might not be enough. 'Zero day'
attacks (and others that the OS distributor has not yet patched for) can
get you. 'Welcome' to the Internet! Sigh. Hopefully you won't run into this.
Unfortunately, this is 'life in the Internet fast lane'. Fortunately,
you aren't a real target for most 'zero day' attacks, you're more likely
to get hit by people who assume that sending you a .zip file will get
you to open it and compromise your system. Never, ever open a .zip file,
even if you think you know who it's from. If it's from a friend, get
them to send it with a different name (something like
myfile.thisisnottheZipfileyouarelookingfor) - but get them to tell you
the name! - and then make sure that it is run through your virus scanner!
If you would like more computer security/virus tips I'm happy to help.
This has become such a pain for everyone on the 'net!

Reminds me of when I first used JNOS on the RPi. Had to replace SD card a couple of times.
Then decided to put jnos on thumb drive so all logs and jnos writing activities go to
thumb drive media instead of SD. Has worked well ever since.

I have a 'workhorse' Pi at the centre of my home network (email, DHCP,
NTP, etc) and found that even a thumb drive suffered after continuous
use. I bought a 60 GB SSD (Solid State Drive) and it's been working now
for more than a year.
Neither SDs nor thumb drives have the automatic redistribution logic of
SSDs, so using them to write data that is being repeatedly altered (like
log files and email folders) can really impact them. Thumb drives do
seem to survive better than SDs, but SSDs are much better still.

Seems to me the problem of jnos filling up a directory was a problem of
a race condition caused misconfigured mbox, so that when smtp tried to
deliver an undeliverable message it tried leaving it in mqueue, but it
left only a blank message and incremented sequence.seq, then tried again
with the same result. Stuck in a loop which ended up filling up the
mqueue directory and finally the system would crash.
I too can't remember how exactly I got rid of the problem, but I do
remember flushing mqueue and deleting sequence.seq (it regenerates on
the next boot). And of course solving the ampr.org addressing problem.
Look at the alias file and the ftpusers files. Check logs too... jnos
and syslog for clues.
As for the thumb drive... I have the same as KD6OAT: a thumb drive with
jnos on it, and the OS on the SD card. It's been running without
problems since PI's became available here in Vancouver, so thats several
years now.
