[Pkg-nagios-devel] Bug#997849: monitoring-plugins-basic: check_icmp fails with 'Socket operation on non-socket' when source IP is specified

[Ez Simo]

Package: monitoring-plugins-basic
Version: 2.3.1-1
Severity: normal


Dear Maintainer,

After upgrade to Debian 11 (bullseye) check_icmp option to specify IP source address stopped working.

# /usr/lib/nagios/plugins/check_icmp -H 8.8.8.8
OK - 8.8.8.8: rta 0,643ms, lost 0%|rta=0,643ms;200,000;500,000;0; pl=0%;40;80;; rtmax=0,773ms;;;; rtmin=0,395ms;;;;

/usr/lib/nagios/plugins/check_icmp -H 8.8.8.8 -s [correct_source_ip_address_here]
check_icmp: Cannot bind to IP address 91.202.124.36: Socket operation on non-socket

check_icmp capabilities are correctly set:

# getcap /usr/lib/nagios/plugins/check_icmp
/usr/lib/nagios/plugins/check_icmp cap_net_raw=ep

Before upgrade to Debian 11 everything was working perfectly correct.

Best regards,
Simo
