Your definitly right about only sending from the root (usr/bin/sendmail) not a typo i tried that since /bin/mail didnt work for me so i thought i would try it out cause thats all it can do i tried placing that in the commands cfg obviusly didnt work... now i also tried making the user root and gave it permission but now i think i played way to much with mail and sendmail i screwed it up big time with the permissions.wat i think will end up doing is reinstalling nagios again..crap I didnt know that sendmail and mail are two different i guess i was wrong .. i mean i did installation word by word as written in manaul i have everything working expet email ? one small question is bin/mail a relay client ? and where is $contactemail$ defined anywhere except commands.cfg i see in the nagios.log file as mention in my eearlier posts that i see its trying to send it out but keeps getting line code error 127 unkown email address (which is my gmail) On 10/4/07, Hugo van der Kooij [EMAIL PROTECTED] wrote: On Thu, 4 Oct 2007, Nedim Bicic right about only sending from the root casue thats all it can do i tried placing that in the commands cfg obviusly didnt work... now i also tried making the user root and gave it permission OK check this out..funny thing is regarding the path /bin/mail doesnt exist anywhere from the root i tryed tracing back so i tryed executing this from the command line and i am able to recieve the email which now at least i know MTA is defintly working: I didnt put any argumetns as u can see this is just to test usr/bin/sendmail -s [EMAIL PROTECTED] works from command line but not from commands.cfg??

If it doesn't, you might consider installing the package which provides it. I didnt know that sendmail and mail are two different i guess i was wrong .. i mean i did installation word by word as written in manaul i have everything working expet email ? Just because you followed the nagios install guide word for word doesn't mean you did it properly. If the system you're building nagios on isn't sane, then you're going to have many other issues no matter how closely you follow the nagios directions. Since you're on RHEL, why are you building nagios from scratch? Why not use the rpms which are built for RHEL and listed on the download section of the nagios page? one small question is bin/mail a relay client ? and where is $contactemail$ defined anywhere except commands.cfg The $contactemail$ variable is defined in your contact definition, and is set by (of all magical options) the 'email' section. i see in the nagios.log file as mention in my eearlier posts that i see its trying to send it out but keeps getting line code error 127 unkown email address (which is my gmail) No. The error you referenced earlier stated that nagios didn't have permission to, or could not find /bin/mail or /usr/bin/printf Did you check the mail log for sendmail to see if it actually got the message but failed to send, or are you simply looking at the nagios.log? Given the vast amounts of typos and misplacings of the /, I would very much recommend that you go back over your configs and make sure you haven't typed them as accurately as you've formed your emails. -- During times of universal deceit, telling the truth becomes a revolutionary act.

Hi, I¹m using a $8.00/month Xen account to run Nagios to monitor 3 machines and 37 services. My issue is that either the Xen machines network or the network I host on gets slow and then I get 37 emails regarding downed services. I read the FAQ and thought that setting notification_interval to 0 would do the trick based on this link: http://www.nagios.org/faqs/viewfaq.php?faq_id=71expand=falseshowdesc=false Unfortunately I just got 28 emails for one machine. I want to setup Nagios so that if the machine is unreachable, then it should assume that none of the services are reachable and it should only send out one alert. Thanks, James - Take Surveys.
