[gentoo-user] Odd cron errors

[gentoo-user] Odd cron errors

[Peter Humphrey]

Hell list,

I don't know when it started, but recently I've been getting error e-mails 
from cron, thus:

Password: 501 Not authorised --- Reply not authenticated

They're all timed at 03:10:0x, i.e. one minute after cron.daily tasks are run, 
and they occur at 7- or 8-day intervals. The only files in /etc/cron.daily are 
logrotate and man-db, neither of which I've touched.

I've been expiring that e-mail folder at 30 days, so I have only four 
instances - I've now set the lifetime to 366 days to allow a history to build 
up.

Anyone have a clue to this? It's hardly earth-shattering, but it might be good 
to find out what's going on.

the error looks like an http error.
Got any crons running wget, curl or lynx?

Only to confirm that I have been getting these on an old 32bit laptop.  I 
suspect that they are caused by chrony which I run on this PC and some passwd 
setup that chronyc requires to connect to the timeservers and update RTC et 
al, via chronyd.  I have not looked into configuring it beyond a rather 
superficial "it'll do for now" level and have not yet added any chrony.keys.  
When I get a moment I will revisit the configuration to add the required key, 
but will need to spend some time going through the man pages first.

As many may recall, I set my system to do emails recently too.  I also
started getting this error.  The subject line is this:

Cron <root@fireball> test -x /usr/sbin/run-crons && /usr/sbin/run-c

Content of email is same as the OP posted.  I'm hoping that the subject
line will shed some light on this.  It seem cron at least triggers a
error of some sort.

I thought so too, but no, I have none of those called by cron. I do have an 
rsync job every 5 minutes to back up my home directory to the file server, and 
I think I saw http-like errors while I was developing that setup. But the 
server has nothing scheduled for that time of night either.

I was beginning to think I was the only one still running chrony :)

My chrony does have a key set up, so I don't think that's the cause. Now that 
you remind me, I changed the setup on 31/5. The Atom LAN server has an 
appalling hardware clock, so I changed things around so that both the Atom and 
this box synchronise over the Internet, and they peer with each other.

Maybe I should split them apart to make them independent. I'll watch them for 
a while first though, to see if a pattern emerges.

Thanks for the idea Mick.

Well, a week ago I did split the two chronys (the one on the server and the 
one on the workstation), but I got another mail at 03:10:05 today. So I guess 
that isn't it.

Please try this:

Go the PC that keeps getting these messages in its logs.  Run:

$ chrony

chronyc> password
password: <manually_enter_your_chrony_Passwd>

If the passwd is wrong, or some characters are incompatible with the terminal, 
then you will get:

"Password: 501 Not authorised --- Reply not authenticated"


You can test this by entering the wrong passwd initially.  Unfortunately, I no 
longer have the PC running chrony to test it here.

Since I'm having the same issue:

root@fireball / # chronyc password
Password:
501 Not authorised --- Reply not authenticated
root@fireball / #

So, that answers that question. It seems a password needs to be set here.

It also seems we have the default setup and we all get this error at the
same time.  I got mine just a bit ago.

Update.  This *SEEMS* to make it happy. 

/etc/chrony/chrony.keys

Make it look something like this:

1 testchrony
2 MD5 HEX:B028F91EA5D93D06C2E140B26C7F41EC
3 SHA1 HEX:1DC764E07B1911FA67EFC7ECBC4B0D73F68A070C

The password is behind #1.  You also need this file set up too. 

/etc/chrony/chrony.conf

This is the key part:

# Tell chronyd which numbered key in the file is used as the password
# for chronyc. (You can pick any integer up to 2**32-1.  '1' is just a
# default.  Using another value will _NOT_ increase security.)

commandkey 1

Should be able to just uncomment the thing.  Restart chrony, or I guess
you could tell it to reload the config, then test again. 

root@fireball / # chronyc password
Password:
200 OK
root@fireball / #

Now let's see if I get a email with a error next week.  o_O

Right, you need to set up your /etc/chrony/chrony.keys file, but Peter said 
that he had configured all this.

Right, and so I had, but somewhere along the line the key had got lost. So 
I've set it again and I'll see what happens next week.

Thanks for the prod, Mick.
