Peter, Thanks for the quick response. We can see a successful SNMP via UDP from Smokeping to the router's Loopback. However, all of our configs are done to use the Interface IP and that is what is sending TCP to this 1 specific router. All other routers successfully go with UDP.
Here is an example of our config: *** General *** owner = Network Management Services contact = [email protected]<mailto:[email protected]> mailhost = mail.host.com sendmail = /usr/lib/sendmail imgcache = /usr/local/smokeping/cache imgurl = cache datadir = /opt/ens/smoke/data piddir = /opt/ens/smoke/var cgiurl = http://host.name.com/smokeping.cgi smokemail = /usr/local/smokeping/etc/smokemail tmail = /usr/local/smokeping/etc/tmail # specify this to get syslog logging syslogfacility = local0 # each probe is now run in its own process # disable this to revert to the old behaviour # concurrentprobes = no *** Alerts *** to = [email protected]<mailto:[email protected]> from = [email protected]<mailto:[email protected]> +someloss type = loss # in percent pattern = >0%,*12*,>0%,*12*,>0% comment = loss 3 times in a row *** Database *** step = 300 pings = 20 # consfn mrhb steps total AVERAGE 0.5 1 1008 AVERAGE 0.5 12 4320 MIN 0.5 12 4320 MAX 0.5 12 4320 AVERAGE 0.5 144 720 MAX 0.5 144 720 *** Presentation *** template = /usr/local/smokeping/htdocs/basepage.html + charts menu = Charts title = The most interesting destinations ++ stddev sorter = StdDev(entries=>4) title = Top Standard Deviation menu = Std Deviation format = Stdandard Deviation %f ++ max sorter = Max(entries=>5) title = Top Max Roundtrip Time menu = by Max format = Max Roundtrip Time %f seconds ++ loss sorter = Loss(entries=>5) title = Top Packet Loss menu = Loss format = Packets Lost %f ++ median sorter = Median(entries=>5) title = Top Median Roundtrip Time menu = by Median format = Median RTT %f seconds + overview width = 600 height = 50 range = 10h + detail width = 600 height = 200 unison_tolerance = 2 "Last 3 Hours" 3h "Last 30 Hours" 30h "Last 10 Days" 10d "Last 30 Days" 30d "Last 400 Days" 400d *** Probes *** +CiscoRTTMonEchoICMP forks = 32 offset = 50% step = 300 timeout = 15 # The following variables can be overridden in each target section ioshost = communitystr...@homerouter_fqdn<mailto:communitystr...@homerouter_fqdn> # mandatory # iosint = 10.33.22.11 packetsize = 56 pings = 5 # tos = 160 # vrf = INTERNET + FPing binary = /usr/local/fping/fping *** Slaves *** secrets=/usr/local/smokeping/etc/smokeping_secrets +boomer display_name=boomer color=0000ff +slave2 display_name=boomer color=0000ff *** Targets *** probe = FPing menu = Top title = Network Latency Grapher remark = Welcome to the SmokePing website for company name. \ Here you will learn all about the latency of our network. + VPN menu = VPN Links # title = VPN Links # ++ WINNAME menu = WINNAME HomeSite to RemoteSite# title = WINNAME HomeRouter to RemoteRouter # probe = CiscoRTTMonEchoICMP # host = RemoteInterfaceIP # RemoteRouter ioshost = communitystr...@homerouter_fqdn<mailto:communitystr...@homerouter_fqdn> # mandatory iosint = HomeInterfaceIP # HomeRouter Tunnel1 Dean Schaibley ________________________________ From: Peter Kristolaitis [mailto:[email protected]] Sent: Tuesday, February 02, 2010 12:38 PM To: Schaibley Dean Cc: [email protected] Subject: Re: [smokeping-users] Forcing SNMP over TCP vs. UDP That probe uses the Net::SNMP module to manage SNMP queries. IIRC, Net::SNMP defaults to using UDP, however it will switch to TCP if it can't reach the host via UDP. Can you confirm whether you can reach the router with UDP from the server hosting Smokeping by using other SNMP tools (e.g. snmpwalk, etc)? - Peter Schaibley Dean wrote: Need some help here. Is there a way to Force SNMP to use TCP 161 or UDP 161? Most all of our smokeping traffic is using UDP 161, but somehow, we do have some that is using TCP 161 (not sure how/why). Our firewalls are only config'd for allowing UDP 161, so when the Smokeping process tries to use TCP it is failing at the firewall (and Security won't allow TCP without justification). We are running Smokeping 2.3.6 with the CiscoRTTMonEchoICMP as the Probe. Any help/tips would be greatly appreciated.
