Hi all! A few days ago I decided to migrate my own servers to Debian GNU/Linux Jessie. Having migrated my firewall, I started getting an error in the Nagios Manubulon plugin check_snmp_int.pl since it does not find the interface eth1.
# ./check_snmp_int.pl -H 10.1.0.10 -l Us3r -x passw0rd0 \ > -X passwOrd1 -L md5,des -w 1500,295 -c 2500,400 \ > -k -B --label -M -B --label -n eth1 ERROR : Unknown interface eth1 This was running smoothly prior to migration, although it now seems to have changed the description: # ./check_snmp_netint.pl -H 10.1.0.10 -l Us3r -x passw0rd0 \ > -X passwOrd1 -L md5,des -n -v Alarm at 10 + 5 SNMPv3 AuthPriv login : Us3r, md5, des Filter : OID : 1.3.6.1.2.1.2.2.1.2.2, Desc : Realtek Semiconductor Co., Ltd.

RTL-8100/8101L/8139 PCI Fast Ethernet Adapter:UP:(1 UP): OK | So I checked the equivalence between ifDescr and ifName: # snmpwalk -v 3 -u Us3r -l authPriv -a MD5 -A passw0rd0 \ > -x DES -X passwOrd1 10.1.0.10 ifDescr IF-MIB::ifDescr.1 = STRING: lo IF-MIB::ifDescr.2 = STRING: Realtek Semiconductor Co., Ltd.

RTL-8100/8101L/8139 PCI Fast Ethernet Adapter:UP (in=93.0Kbps/out=13.1Kbps):(1 UP): OK | It's a pity If it can not solve because quite a while I was using the check_snmp_int.pl plugin and was very happy with their results. But now in Debian Jessie I'm having this problem. It seems that something has changed in the SNMP service included in the new version of Debian since before (on Debian Wheezy) the description matched the ifName: # ./check_snmp_netint.pl -H srv01.freesoftware -C public -w 1500,295 -c 2500,400 -n -v Alarm at 10 + 5 SNMP v1 login Filter : OID : 1.3.6.1.2.1.2.2.1.2.2, Desc : eth0 OID : 1.3.6.1.2.1.2.2.1.2.1, Desc : lo Name : eth0, Index : 2 eth0:UP:(1 UP): OK | I think it is easier to identify interfaces such as eth0, eth1, etc, rather than by its manufacturer/model. Any suggestions to return to the original behavior? Thanks in advance. Best regards, Daniel -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
