Hello,
i use nagios-plugins 1.4.5 on opensuse 10.2 and have the problem to
check a host via snmp which has a singe character in its hostname.
# /usr/lib/nagios/plugins/check_ifoperstatus -H blabla.x.mydom.loc -C
mycomm -v 1 -k 1 -t 30 -D w
returns error / syntax.
same command on blabla.xy.mydom.loc works fine.
patching as follows soved the problem:
--- /usr/lib/nagios/plugins/utils.pm.old 2006-11-28

- } elsif ($host1 =~
m/^[a-zA-Z0-9][-a-zA-Z0-9]+(\.[a-zA-Z0-9][-a-zA-Z0-9]+)*\.?$/) {
+ } elsif ($host1 =~
m/^[a-zA-Z][-a-zA-Z0-9]*(\.[a-zA-Z][-a-zA-Z0-9]*)*\.?$/) {
return 1;
} else {
return 0;
http://tools.ietf.org/html/rfc1035 says:
"...There are also some
restrictions on the length. Labels must be 63 characters or less.
For example, the following strings identify hosts in the Internet:
A.ISI.EDU XX.LCS.MIT.EDU SRI-NIC.ARPA"
is this a bug in nagios?
regards, georg
