[Sshguard-users] Problem with blocking "strings" not being IPs

[Peter V. <sku...@gm...>]

Hi all,
anybody seeing/saw similar messages? Once this occur the SSH isn't
accessible at least our Zabbix monitoring reporting that.

Jun  4 21:31:43 server sshguard[8003]: Releasing <B0><EB><C0>^A after
1372366479 seconds.
Jun  4 21:31:43 server sshguard[8003]: Setting environment:
SSHG_ADDR=4;SSHG_ADDRKIND=4;SSHG_SERVICE=100.
Jun  4 21:31:43 server sshguard[8003]: Run command "case
$SSHG_ADDRKIND in 4) exec /sbin/iptables -D sshguard -s $SSHG_ADDR -j
DROP ;;
 6) exec /sbin/ip6tables -D sshguard -s $SSHG_ADDR -j DROP ;; *) exit
-2 ;; esac": exited 1.
Jun  4 21:31:43 server sshguard[8003]: Release command failed. Exited: -1

System information:
 - Debian Squeeze LTS
 - iptables 1.4.8-3
 - sshguard 1.4-2
 - linux-image 2.6.32-48squeeze8

Was this bug fixed already? Are the IPs checked for validity before
they are blocked? Could be that it was related to some bug in kernel.
Sorry for a little late reporting. Hope that somebody would be able to
explain what could happen and make us sure all is fixed in new
versions.
