Does anyone know of a way to track TCP/IP traffic by TCP/UDP port and/or by process/daemon with CentOS? I know a variety of ways to track it in total (e.g., ifInOctets & ifOutOctets with SNMP), but I'm not sure how to be approach seeing traffic by application, port, or process. One option would be to write something that would sift through different stuff for each daemon (for example,

Hi, i'm running CentOS 6.0 on my server and installed mrtg from the rpm-package mrtg-2.16.2 . I also installed the depending packages perl-IO-Socket-INET6 perl-Socket6 .... mrtg works fine with IPV4-Addresses. When i specify a Target by IPV6-Address (or hostname resolving to a V6-address) mrtg fails. Here i have a small sample-config for V4 which is working: LogDir: /tmp ThreshDir: /tmp

Hi all, I hope someone can help me with this one. I'm trying to graph all traffic on the localhost's network card with Cacti. >From what I understand I should use SNMP to query the traffic, but I can't seem to get SNMP info for the network interface. I have installed all the necessary snmp tools, "yum install snmpd net-snmp net-snmp-utils net-snmp-devel net-snmpt-libs "

Hi, I''ve migrated my tc configuration from CBQ to HTB. One problem appeared. Htb seems to miscalculate the bandwidth for classes with greater rates. For rates below 2Mbit there is almost no difference between the configured and the measured rate. For large ones the problem starts. My root class has 10Mbit rate and when the interface has heavy trafic the measured bandwidth

Hello all, Thank you in advance for a great FOSS project. Also, thank you for reading my question. I have a CyberPower OR1500LCDRTXL2U with an RMCARD205. There are a handful of devices plugged into the UPS. I received a message today saying to send upsc output to NUT developers after this message: "No matching MIB found for sysOID '.1.3.6.1.4.1.3808.1.1.1'" root at

Hello Centos People, I have a CentOS 5.3 box that had a total of 5 ethernet cards in it. It functions to share an internet connection with 4 different subnets. All works fine, except I'm noticing that my MRTG traffic graphs are wrong. Further digging with snmpwalk reveal that the order of the ethernet interfaces changes every time the machine is rebooted to a different order. For

Hi, I've just begun putting xen domains on an etch dom0 (my other servers being sarge with backports at this time). I've noticed that when a domain is restarted or shut down, SNMP believes that the interface is still there and a new interface with the same name has been created. For example, on an snmpwalk: [...] IF-MIB::ifDescr.24 = STRING: v-deep IF-MIB::ifDescr.28 = STRING: v-isst

Posted this to xen-users back in Oct (http://www.gossamer-threads.com/lists/xen/users/186768), but just confirmed that I''m still seeing this behavior on 4.1. Polling the UCE-SNMP-MIB::ssCpuRawIdle counter results in a total that''s double the actual number of cpu''s on the system, so for example: nms ~ # snmpwalk -v 2c -c ''XXX'' xen1

I want to check some client OpenVPN TUN interfaces with MRTG running at my VPN server, so I have to specify their OID interface numbers in mrtg.cfg. The problem is, these numbers are dynamic, as they may change whenever OpenVPN restarts for any reason... so, how can I write stanzas such as Target[somehostvpninterface] : ifInOctets.X&ifOutOctets.X:public@ <SOMEHOST.IP> without wiring up

Hi, My HTB shaping is working perfectly, and i have setup a bridge and hosts behind the bridge are now getting only the bandwidth they are supposed to get. Thanks to every one here for helping me out :) Now I am thinking of making a graph of traffic going through various classes. Is their any thing readily available for it, or is parsing the output if tc and passing it to rrdtool the

Hi, We are using Zenoss to monitor a number of paravirt Linux hosts (using the xen net device), it appears that an snmp query to the paravirt hosts is reporting the interface speed as 10mbit - which is significantly lower than what it really is (the dom0 host has 1gbit networking). This causes the occasional spurious error from the monitoring tool as it notices that a host is using 75% of its

Hi all, I think the problem is related with the latest nut update (now I'm using version 2.4.3) # snmpwalk -Os -c public -v 1 192.168.20.60 [...] mib-2.33.1.1.1.0 = "" mib-2.33.1.1.2.0 = "" mib-2.33.1.1.3.0 = "" mib-2.33.1.1.4.0 = STRING: "2.39.DK520" mib-2.33.1.1.5.0 = "" mib-2.33.1.2.1.0 = INTEGER: 2 mib-2.33.1.2.2.0 = INTEGER: 0

Does anyone know if the 3.8 update will fix the long-standing problem with snmp interface counters on 64 bit machines? I think it was mentioned in the RH notes, but they said that a year ago too... (The problem is that the 32 bit counters don't wrap correctly so mrtg/cacti graphs go crazy after 2 gigs of data have gone by). -- Les Mikesell lesmikesell at gmail.com

Hello, I have two UPS from PowerWalker: VFI 1500RM LCD and VFI 3000RM LCD both equiped with SNMP card, but NUT with snmp-ups does not support them. PowerWalker declare support RFC1213, RFC162 but there is a problem with some snmp values: # upsdrvctl start Network UPS Tools - UPS driver controller 2.6.4 Network UPS Tools - Generic SNMP UPS driver 0.66 (2.6.4) Detected 3K on host 10.0.0.236

So, just to play with vnics with 106, I have... e1000g2 plumb''d with 192.168.85.10 vnic0 is created on top of e1000g2 with 192.168.85.22 I snoop on e1000g2 to see the traffic. I ping 192.168.85.22 and it works. I stop the snoop on e1000g2. I ping 192.168.85.22 and it doesn''t work. I start the snoop on e1000g2. I ping 192.168.85.22 and ping works. Is this a new feature with

Hello Folks, I am looking for ideas on how to create 1000 DOT1X sessions generated from a Linux BOX. DOT1X is a name for EAP packets that travel in an Ethernet environment and is used to transport authentication information before a PC will get access to the network, it is based on RFC-3748. Having this in mind a virtual interface will need a MAC address and an eventually IP (I want to stress out

I have a requirement in my current project to support multiple co-located zones on the same VLAN. Our current deployment OS is Solaris 10 Update 4. I''d like to use exclusive IP zones, but I gather the only way to currently have multiple exclusive zones with interfaces on the same VLAN is through the use of VNICs. From my initial look at S10u4, it seems VNIC support been not yet been
