SNMP a speedtouch 510i...TCPDUMP...

[Lubomir Majersky]

pc na ktorom prevadzam monitoring je priamo pichnute do switcha "spidtacu"
, s tym nie je problem, spravna IP adresa, spravny if, nespustam bez 
specifikacie.....
skusal som pred chvilou 2x tcpdump host IPadresa...

1. cast vypisu
tcpdump host IPadresaADSL
tcpdump: listening on sis0
14:00:01.088238 ns.xxx.sk 3215 > IPadresaADSL.snmp: C=mycomunity 
GetRequest(28)  system.sysUpTime.0
14:00:03.094520 ns.xxx.sk 3215 > IPadresaADSL.snmp: C=mycomunity 
GetRequest(28)  system.sysUpTime.0
14:00:05.104487 ns.xxx.sk 3215 > IPadresaADSL.snmp: C=mycomunity 
GetRequest(28)  system.sysUpTime.0
14:00:07.114502 ns.xxx.sk 3215 > IPadresaADSL.snmp: C=mycomunity 
GetRequest(28)  system.sysUpTime.0
14:00:09.124523 ns.xxx.sk 3215 > IPadresaADSL.snmp: C=mycomunity 
GetRequest(28)  system.sysUpTime.0
14:00:11.150442 ns.xxx.sk 3961 > IPadresaADSL.snmp: C=mycomunity 
GetRequest(35)  interfaces.ifTable.ifEntry.ifInOctets.104 .ios.org[|snmp]
14:00:11.151451 IPadresaADSL.snmp > ns.xxx.sk.3961: C=mycomunity 
GetRequest(35)  interfaces.ifTable.ifEntry.ifInOctets.104=9102618 [|snmp]
14:00:26.941201 arp who-has IP1 tell IPadresaADSL
14:00:27.027984 arp who-has IP2 tell IPadresaADSL
....
^C

0 packets dropped by kernel

pozn. vzdy na celej hodine sa mi spusta cez cron iog, ktory cita octety z 
if - spustil som teda
tcpdump o 14.00 hod a po chvilke som to stopol

2. cast vypisu - spustil som to par sekund po prvom, na obrazovke nic a po 
preruseni
tcpdump host IPadresaADSL
tcpdump: listening on sis0
^C
335 packets received by filter
0 packets dropped by kernel

Cez ten adsl ide proste veskera komunikacia z a do internetu a nevidim nic 
resp. ten co som
 uviedol ako prvy vypis je prvy krat mnou videny...
Pripominam, ze z toho pc monitorujem aj druhe pc ktore je do pichnute priamo 
do switcha ADSL a nemam problem
ADSL je nakonfigurovany bez vsetkeho - ziadne obmedzenia
