Configuring Zabbix on a Fedora system, the icmp probes always get a “down” response, the reason is simple, Zabbix uses “fping” command to test the service and sends the “-S” parameter to the fping binary to specify the source ip of the probe, BUT on fedora the fping command doesn’t recognize the -S

# FPING VERSION
[root@Zeus2 sbin]# rpm -qa | grep fping
fping-2.4b2-9.fc11.x86_64

# FEDORA VERSION
[root@Zeus2 sbin]# cat /etc/redhat-release
Fedora release 11 (Leonidas)

# FPING OUTPUT
[root@Zeus2 sbin]# fping -q -C5 -p300 -b128 -t100 192.168.3.170 -S1.1.1.1
fping: invalid option -- 'S'

Ubuntu accepts -S

cash@sistemacasero:~$ fping -S
fping: option requires an argument -- 'S'

So, I created a little perl wrapper to strip the parameter on fping command and send the rest of the parameters, you have to rename the original fping command to fping.dist and name this script fping on /usr/sbin directory.

#!/usr/bin/perl
#open (DEBUG, '>/tmp/logfile.fping');
my @params;
foreach (@ARGV) {
        #print DEBUG $_."\n";
        if ($_ =~ /\-S/) {
                #print DEBUG "doh!\n";
        } else {
                push(@params,$_);
        }
}
my $strippedprm = join(" ", @params);
#print DEBUG $strippedprm;
my $CMD=system("fping.dist $strippedprm");
#close(DEBUG);

Now yo get a response from Fping command on Fedora, obviously fping will not use the SOURCE INTERFACE paramenter defined in zabbix server configuration on icmp probes, but it works fine, and you get the icmp status from zabbix remote hosts.

[root@Zeus2 sbin]# fping -q -C5 -p300 -b128 -t100 192.168.3.170 -S1.1.1.1
192.168.3.170 : 0.18 0.29 0.22 0.27 0.23
