Also, try running /usr/sbin/sensors-detect -- it will tell you how to set things up so that you load the right modules. Once you've done that, then the /usr/bin/sensors will give you all the information you want to know (and more besides:) Note that you probably don't want or need to load the eeprom driver, it is used to give information about installed ram (and, I assume, get access to the cmos). (At least this is my observation and assumption about what it is for). And do make sure that you run "sensors -s" after you load the required modules. (I have it as a "post-install" parameter in /etc/modules.conf). One hint... you can automatically have your lm-sensors drivers loaded when you modprobe i2c-proc. For example I use this: add above i2c-dev i2c-proc add above i2c-proc i2c-viapro add above i2c-viapro w83781d post-install i2c-w8381d /usr/bin/sensors -s alias eeprom off (Obviously have a VIA chipset on my m'board, and don't want/need the eeprom module loaded at all. I also have some more magic in there to automatically load the bttv drivers for my tv capture card). I do "modprobe i2c-dev" in /etc/rc.d/rc.local and the lm-sensors modules are then automagically loaded at bootup.

Yep, excellent suggestion... it is amazing just how much information can be obtained with snmp. Simply enable the daemon on the target boxes and use "snmpwalk <ip> public" on another box to get _lots_ of information out of it. (The parameters can be fine-tuned to get specific information). Just be aware of the security issues involved, in particular know that snmpd uses tcp_wrappers. The ports should be firewalled from the internet anyway - especially if you are using the protocol. > Venkatesh Cheers Tony _______________________________________________ Redhat-devel-list mailing list Redhat-devel-list@redhat.com https://listman.redhat.com/mailman/listinfo/redhat-devel-list
