problem with configuration

[Marek Niemczyk]

Hi John,

I have hard time getting hcron to work. I'm using Raspbian Wheezy on Raspberry Pi. Installed it via deb package.

My current config:

~/.hcron/raspberrypi/events/test:

as_user=

host=localhost

command=whoami > /home/pi/hcrontest/test.out

notify_email=

notify_message=

when_month=*

when_day=*

when_hour=*

when_minute=*

when_dow=*

template_name=

/etc/hcron/hcron.allow

# user names

pi

root

running 

ssh localhost whoami > /home/pi/hcrontest/test.out

works ok, the file is being created with "pi" (username) inside. So the ssh is configured properly, I guess...

When I'm trying to reload hcron with 

hcron-reload

I can see in log file:

/var/log/hcron/hcron.log:

2017-09-29T13:37:00.489829|work||0|0.000635

What am I doing wrong?

Hi,

Since you are using a rpi, I take it you installed from git/source. I suspect that there are some required directories

that have not been setup. See the postinst file for DEBIAN:

https://bitbucket.org/hcron/hcron/src/09a68e4fc297/control/hcron/DEBIAN/postinst?at=master

It may be easiest to just copy-paste lines 12-40 (as root). Then retry the hcron-reload (as pi).

Also, to run on the localhost, make sure that the hcron.conf has:

{
   "localhost": True,
   ...
}

For the hcron.allow, see the docs:

https://expl.info/display/HCRON/hcron+Guide#hcronGuide-hcron.conf

I will provide more information on the setup for those that install from source.

Hi,

Sorry, the key name to use in hcron.allow should be "allow_localhost" not "localhost".

Thank You for Your response!

I was installing hcron from deb package with 

sudo dpkg -i hcron_0.21_all.deb

But I tried to compile it from sources earlier, using "make install" - but I failed. Anyway...

My hcron.conf

# hcron.conf

{

    "allow_localhost": True,

    "allow_root_events": True,

    "command_spawn_timeout": 15,

    "events_base_path": None,

    "log_path": "hcron.log",

    "max_events_per_user": 50,

    # hidden files, emacs backup files

    "names_to_ignore_regexp": "(\..*)|(.*~$)",

    "smtp_server": "localhost",

    "test_net_username": None,

    "use_syslog": False,

}

I executed mentioned lines 12-40 as root, no error message were shown. Then I ran hcron-reload but it didn't help. Error is still there:

Maybe I can somehow clean up some directories that might be corrupted and reinstall?

Hi,

What is the output from "hcron-info --fqdn"? That hostname value should be used for
the home of the events:

~/.hcron/<hostname>/events

Is there a file at:

~/.hcron/<hostname>/snapshot

Is the snapshot readable?

tar tvfz ~/.hcron/<hostname>/snapshot

Are the /var/lib/hcron directories in place? If you do:

ls -l /var/lib/hcron

do you see something like:

total 8
drwxr-xr-x 2 root root 4096 Sep 20 08:23 event_lists
drwx------ 2 root root 4096 Sep 20 08:23 tree

What about the /var/spool/hcron? If you do:

ls -ld /var/spool/hcron

do you see something like:

drwxrwxrwt 2 root root 4096 Sep 20 08:23 /var/spool/hcron

Bingo! My snapshot file was in fact a directory (I've created it manually and thought it should be dir) and what is worse, it was owned by root. After granting ownership of ~/.hcron/raspberrypi/ directory to user pi and deleting snapshot dir, snapshot file was created and it worked.

Thank You very much for Your assist :)

Hi,

Good to hear. I hope it proves useful to you.
