similar to: Synthesize low batt (LB) fron SNMP UPS which does not support this?

Makes sense, and a PR is a way to solicit feedback :) I'd document this for ups.conf (man page and examples), including a note that for devices which do provide a healthy LB these values may be set to 0 safely. Wondering if non-zero defaults should be there anyway. @Community, WDYT? Also, this critical-state check should be done only when the UPS is on battery (and perhaps not calibrating),

Hmm, looking at status_commit(), if the UPS actually reported just ?OB", but the ?ignorelb? logic kicked in, wouldn?t status_commit() change it to ?OB LB?? And would clients interpret that correctly? And, assuming status_commit() is called, is the status so saved what?s returned on a future client query? I?m really unsure how all of this works. I don?t suppose there?s some kind of ?general

My $0.02: LB is baked in to nut behavior. So if a UPS doesn't report LB, then it makes sense to synthesize it. Synthetic LB is the cleanest fix at the earlier processing point. One could have a config that is basically synthetic-lowbatt-percent that generates LB if (as Jim says) on battery, not calibrating, and batt% <= that. One could have a similar config

Hmm. Is there maybe something there already that will do this? Maybe kind of back-handed. In drivers/dstate.c, I see: In status_init(), if ?driver.flag.ignorelb? is set in the driver state, the ?ignorelb? flag is set. In status_set(), if ignorelb is set, and the status being set (presumably from the UPS) is LB, it?s ignored. In other words, LB reported by the UPS is ignored. In status_commit(),

It there a way to get the genericups driver to set a output on the serial port? On the APC BackupPro the will pull the BattLow line low with a pull down resistor it's up to you to from the PC side to pull the line high with a pullup resistor from one of the RS232 output pins. Then monitor the line with another pin. Regards Rabie -------------- next part -------------- An HTML attachment was

I have been using kernel from centosplus for a few months. It quite stable and have support for my TV card and ntfs partitions. However, after the last yum update, kernel 2.6.9-34 from the update repo has been installed with all other updated packages. In fact, i still have kernel 2.6.9-22.106.unsupport on my system but whenever i use this kernel, the cupsd can not start. Can anyone tell me

Hello, I've got an Ubuntu Workstation integrated in an Active Directory domain. I'm really authenticated to the domain (with Kerberos clients, Winbind and Samba) and I can list the users of the domain with the wbinfo command. There's a DFS root share that is defined on each DC of the AD domain. When I try to mount that share with the mount.smbfs command : # mount -t smbfs

I've seen many posts on this subject and several days researching but have not understood much of what I'm reading. In over my head. Any help appreciated. Here are facts.... 1. I set up the samba on linux box. 2. connected two windows 98SE machines 3. All machines connect to router 198.168.0.1, and use DHCP 4. I set up a public directory on Linux box 5. I can browse with

Hi there, we are using a couple of Diskless Linux Workstations in conjunction with PXE capabable Network cards to boot the system. This works fine using pxelinux. However, there are a few workstations left, which are not able to boot via PXE and thus this workstations need a Kernel on a floppy disk and an additional initrd image. The Problem with is, that both of them don't fit on a floppy

This is kind of a tricky problem. I have a forum (simplemachines) containing all of the users for my RoR app. The question is, how would I authenticate a user of a foreign app before giving them a session with the RoR app? (It''s not possible in this case to create a new ''user'' table in the rails app) Thanks -- Posted via http://www.ruby-forum.com/.

Hello folks, I have a question regarding a sweex product. Its bundled with UPSmart v 2.12. I installed nut accordingly to the user manual included in the software.

Hello, I have a Legrand Keor T [1] monitored via snmp, everything seems to work fine, upsc output looks good [2] except that I can?t get the low battery state "OB LB? as usual (it works fine with others UPS like APC or Dell).
