Initializing nettl.LOG000

[Lai Nee Shyang_1]

Hi there,

I suspect my nettl.LOG000 is corrupted, causing netfmt -f /var/adm/nettl.LOG000 to core dump. This is what I did to initialize nettl.LOG00:
====================================
/sbin/init.d/nettl stop
mv nettl.LOG000 nettl.LOG000.bk
touch nettl.LOG000
/sbin/init.d/nettl start
====================================
The nettl.LOG000 is 128Byte size after restart, but netfmt -f cmd produce nothing now probably no logs has be entered.

Is my steps correct ?

thanks

Lai

Hi,

what are the entries in /etc/nettlgen.conf ?
Maybe you they are not correct and you should check them

Hi Franky,

Pardon me for asking. How do I determine if the entires are correct ?

I cut out the nettlgen.conf, remove all lines with "#",this is what I have :

Hi Lai,

the nettlgen.conf file looks good to me.
Two more thoughts: is the NETTL=1 enty set in /etc/rc.config.d/nettl and is the nettl proc up and running ?
On the other site it can take some time until the nettl.LOG000 file is filled up, because it needs certain circumstances to make entries in there

Just my thoughts

Regards

Franky

Yo Franky

Thanks. I guess I'll have to simulate some network problems to generate errors to assertain if the nettl is working fine.

Thanks Franky, for your response and reading thru the conf file.

Hi Lai,

To answer your first question, I've used that procedure before to clear up a corrupt nettl.LOGXXX trace file. When you recreate the log file it will be 128 byte size since no logging has occured.

To test your logging you can increase the log level to informative, you should see data written to the nettl.LOGXXX file.

To view logging:

# nettl -status |pg

Notice the default log level per subsystem is set to error and disaster.

Increase log level for ICMP

# nettl -log i w e d -entity ns_ls_icmp

Check status:

# nettl -status
NS_LS_ICMP INFORMATIVE WARNING ERROR DISASTER

Now create some ICMP trafic, ping the broadcast address etc.

You can increase nettl logging for all entities which should definately produce some log messages.

# nettl -log i w e d -entity all

To set it back to default do this.

# nettl -log e d -e all

Verify by checking the status again.

# nettl -status

You should be able to format your log file now.

# netfmt -Nnlf /var/adm/nettl.LOG000

Hope this helps,

Todd

Yippe..!!!

Thanks Todd,

That's brilliant. I'm able to generate enuf logs to assertain that the nettl.LOG000 is fine and netfmt -f gives no more core dump.

Proble solved...

Thanks again man !!
