 |
|
Hi all,
I have installed nagios and set it up for two servers. The ping functionality works great but the services monitoring just reports
| Quote: | | Cannot map "tcp" to protocol number |
for all services. I assume this has something to do with looking up the service number presumably in the /etc/services file. The services are stock standard ie http and smtp. I am using ldap to store servive info and this is lookedup succxessfully,via nssswitch, by postifx. Not sure why nagios cant find this info.
any help is appreciated.
thanks

It's trying to match tcp to the number 6 in /etc/protocols. Make sure /etc/protocols includes these lines: | Code: | ip 0 IP # internet protocol, pseudo protocol number
icmp 1 ICMP # internet control message protocol
tcp 6 TCP # transmission control protocol
udp 17 UDP # user datagram protocol
ipv6 41 IPv6 # IPv6
ipv6-route 43 IPv6-Route # Routing Header for IPv6
ipv6-frag 44 IPv6-Frag # Fragment Header for IPv6
gre 47 GRE # General Routing Encapsulation
ipv6-icmp 58 IPv6-ICMP # ICMP for IPv6
ipv6-nonxt 59 IPv6-NoNxt # No Next Header for IPv6
ipv6-opts 60 IPv6-Opts # Destination Options for IPv6 |
