/bin/sh: /usr/local/bandmin/bandmin: No such file or directory

[oizumi]

I also started to receive this messages this week. I Googled it and some people suggest to disable this command from Cron. Not sure if this is the correct solution.
Does anyone know how to fix it?

Bandmin Removed Warning

Warning:
We removed the Bandmin feature from cPanel & WHM version 58. The Bandmin feature only exists in cPanel & WHM version 56 and earlier.

CSF Changelog

7.00 -
Ensure /usr/local/bandmin/bandminstart exists and is executable on cPanel servers before using it

csf.conf

# This settings re-enables the cPanel Bandwith chains after iptables is
# configured. If bandmin is not functioning, or you don't use the bandmin stats
# you can disable this option
LF_CPANEL_BANDMIN = "1"

Unless you have a cPanel server v. 56 or earlier – and using bandmin necessarily – it should not be something you have or need. CSF is supposed to be checking for its existence before trying to stop or restart it, but that must be failing somehow.

Do you have LF_CPANEL_BANDMIN = "1"? If so, set to 0 and that should force CSF to ignore it. HTH

I have LF_CPANEL_BANDMIN = "OFF" configured. Yet I still get emails.

/bin/sh: /usr/local/bandmin/bandmin: Is a directory

How can I disable any emails concerning 'bandmin' from being generated. I get them 2-3-4- times a day.

[BallyBasic79]

I'm glad that you posted your setting. It says off, but it is not off.

I have LF_CPANEL_BANDMIN = "OFF" configured. Yet I still get emails.

To verify this issue, I searched the source code for this setting. Line 1293 of the dostart function in csf.pl checks for two positive conditions:
setting is on and bandminstart exists on your disk.

Code: Select all

	if ($config{LF_CPANEL_BANDMIN} and -x "/usr/local/bandmin/bandminstart") {

Note that the LF_CPANEL_BANDMIN test is true or false – a value exists or it does not.
"1", "TRUE", "nope" are true values.
"0", "" are false values.
And there is a test to ensure that bandminstart exists, so you must still have that on your disk.

I suggest that you change your config to LF_CPANEL_BANDMIN ="0" and check for any other settings that needs to be corrected similarly. Then restart csf+lfd. You might also check for /bandmin and remove it. HTH

[LukeDouglas]

I checked the /etc/csf/csf.conf file and here are the settings:

# This settings re-enables the cPanel Bandwith chains after iptables is
# configured. If bandmin is not functioning, or you don't use the bandmin stats
# you can disable this option
LF_CPANEL_BANDMIN = "0"

I had removed the /usr/local/bandmin folder..

Any other ideas?

[BallyBasic79]

Will you post an example of the message with subject line and content? (Feel free to censor sensitive info.)

Here are three of about 30-35 just in the last month.

Dude – this isn't adding up.

Which CSF version are you running? Please confirm.

The Mon, Sep 30, 2019 at 11:40 AM message below states that /usr/local/bandmin/ exists, but you state that it doesn't.

/bin/sh: /usr/local/bandmin/bandmin: Is a directory

I've been through the source code several times and not found anything related to bandmin but a check for the setting and directory existence when stopping and restarting.

About the time of these messages, do you see the following in the lfd.log?

Restarting bandmin acctboth chains for cPanel

The only other thing is maybe some cron job is old and testing bandmin. You could check in:
'/etc/cron.d','/etc/cron.daily','/etc/cron.hourly','/etc/cron.weekly'

[LukeDouglas]

I manually removed the /user/local/bandmin directory. I checked all cron jobs and did not see any bandmin text anywhere.
