how to change ipmi user with one command

Question

i want to change existing user password. i ran this command ipmitool -I lanplus -H 192.168.1.1 -U USER -P 'PASSWORD' user set password 10 "&UJM2wsx"

i got an error IPMI command failed: Request data field length limit exceeded Set User Password command failed (user 10)

when i ran same command without password at the end i was prompted to insert password twice and it worked. is there a way to echo password twice to ipmitool user set password command?

p.s i tried to delete the user and re create it but there is not delete option from cli only from web gui

I had a similar issue when trying to update the password of user 2 (ADMIN) on one of my servers using ipmitool.

I was trying to set the password using the following command; ipmitool user set password 2 ADMIN

This failed with the following error: IPMI command failed: Request data field length limit exceeded Set User Password command failed (user 2)

The way to fix this is actually quite simple. Since some time, Supermicro actually does not allow certain passwords for BMC users unless they have the following requirements: use lowercase, capital, numbers and special characters.

So, to set my password I included this using e.g. Admin123! and it worked like a charm.

Ah, that's what it means, thanks. Fwiw, I didn't need the ! – Martin Dorey Apr 07 '23 at 17:51 — Martin Dorey, Apr 07 '23 at 17:51

This below is incomplete:

"The way to fix this is actually quite simple. Since some time, Supermicro actually does not allow certain passwords for BMC users unless they have the following requirements: use lowercase, capital, numbers and special characters."

How to put your own (and maybe insecure) password:

You need to login in the ipmi webpage with the current password.
Go to 'Configuration>Users>'
Click on the 'here' link:

"For more advanced user settings, please click. here"
Then lower the password security requirements.

That's all.

This is really helped. – Namasivayam Chinnapillai May 08 '22 at 06:00 — Namasivayam Chinnapillai, May 08 '22 at 06:00

It doesn't require to echo the password twice, both must work. Not sure, why you are getting data field length exceed error.

try it with ipmitool -I lanplus -H 192.168.1.1 -U USER -P 'PASSWORD' user set password 10 "&UJM2wsx" -v

also with ipmitool -I lanplus -H 192.168.1.1 -U USER -P 'PASSWORD' user set password 10 "&UJM2wsx" -vv

Also, make sure user 10 is having a proper user name first, with "ipmitool user list" command.
