View 2 Replies View RelatedI'm managing a residential network. Each flat is its own subnet, and can only communicate with the other flats through a router (i.e. no broadcast). 95% of these 300 subnets only contains windows computers (from lambda users).
My final goal is to be able to browse the entire network from any computer.
I set up a samba server acting as a wins server, and every computer is aware of it because it is registered in the dhcp. So name resolution is working fine for everyone.
The same samba server is set to be the "Domain master browser":
workgroup = WORKGROUP
wins support = yes
prefered master = yes
local master = yes
domain master = yes
os level = 65
When I browse the network (using "net view" or "browstat view"), I can only see the servers which are in the same subnet as the domain master browser.
Now, when in a subnet the computers arrange themselves to find a "local master browser", the only visible computers are the one in that subnet.
What I don't understand is why all the local masters don't synchronize their lists with the domain master.
So, to sum up, every subnet get the following behaviour:
-if a local master is elected, the only visible computers are the one in the same subnet.
-if no local master is elected, the only visible computers are the one in the subnet of the domain master.
-if I add another samba, configured as a local master winning all elections, then the magic is working and the lists are synchronized.
What is expected:
-every computer can see all the computer from all the subnets.
This worked fine in 9.04, but doesn't in 9.10 (fresh install).
If I tell my ssh-agent about a private encrypted key via "ssh-add .ssh/mykey" then everything works fine.
But if I log out and then log back in it's not there and there is no Gnome prompt to ask for the password to decrypt. So I have to do an "ssh-add" everytime I log in.
how an agent itself generate trap on some particular situation arises

View 1 Replies View RelatedI have a load balancer with 2 web servers behind it. The web servers rsync with cloud storage to update their apache directories 1 time every hour. Apache is just running php pages that pull/push data to a DB so they dont need to be updated that often. However I need to figure out how to implement a Master/Master MySQL setup to have my web servers point to for the PHP stuff. I need to implement it without having a single point of failure. The Load balancers are useless for failover as they only detect availability based on Ping request. So putting a master/master setup behind a Load Balancer is out. what is the best way to setup the master/master mysql in a HA setup without the use of a load balancer provided by the host?

how to make mib file for snmp....
View 3 Replies View RelatedI have enabled SNMP monitoring in my debian box (using apt-get install snmp) and configured it to allow my PC to query the server.
I'm able to query the server and get SNMP data but when I get STG to give me a per/second graph of the interface octets, it only updates the data every 12 seconds or so.
Is this a setting in SNMP which could be causing this problem? If so, how can I enable it so that SNMP can give me up to the second octet rates.
2 machines (one of them working as a server to monitor the network with IP 192.168.100.110 and the other one to be monitored with IP address 192.168.100.1):
In the first machine:
snmpwalk -v1 localhost -c public sysName (working fine)
snmpwalk -v1 192.168.100.1 -c public sysName (don't works -> Timeout: No Response from 192.168.100.1)
In the monitored machine:
snmpwalk -v1 192.168.100.110 -c public sysName (it works)
snmpwalk -v1 localhost -c public sysName (dont works -> Timeout: No Response from localhost)
I'm trying to sniff snmp traps being sent to a NMS. I'm setting -s to 0 but when I start sniffing, some of the packets, instead of being decoded, show me messages like this:

I have created this thread as it sis realy hard for me to send traps from my Linux workstation... I m lost with v1/v2/v3 snmp... So here is the initial configuration: (without traps)

rwcommunity MyL33tP4ss 10.5.32.202
rwcommunity MyL33tP4ss 127.0.0.1
syslocation "FR"
syscontact root
From there i can "poll" my system. But what should i do if i want my Linux system sending traps when disks are full or system overloaded etc...I have found information on Internet but not easily understandable It is for v3:
rwuser admin
createUser admin MD5 mypasword

# From there i would have to comment the lines regarding the communities

10.5.32.202 is my management host ... is this config ok ? But it seems that trap2sink is for v2 ? How does it work ?

View 1 Replies View RelatedI am trying to monitor a Centos 5.3 box using SNMP and I am having a lot of trouble getting the data that i need from it. Everytime I try to get information from the UCD-SNMP MIB it returns "End of MIB". It is my understanding that UCD-SNMP is a standard package when Net-SNMP is installed and should always be there. Then why can't I access it? I have tried removing the reinstalling Net-SNMP, but that hasn't worked. My server is update date on all it's patches as well. It is quite old hardware, but I don't believe that should affect SNMP from being gathered. Iptables is down, and I cant' even get it from the local machine.

how can I configure snmp to receive traps from diffé²¥nt machines??
View 1 Replies View RelatedI have a pair of special radio-devices which support SNMP, but the problem is, that if I snmpwalk those devices, I only see few generic values(sysContact, sysDescr, sysServices etc) and nothing else. Most likely I need MIB files so NMS could know what values can be asked from the radio devices? If yes, is there a possibility to get all the OID's device supports without MIB files as those devices have been out or production for years?
