hi,
i would also like to ask, in my truss output, it tries to read
xstat(2, "/etc/resolv.conf", 0x080472F8) = 0
the /etc/resolv.conf file. I notice in this file, there is a:
Code:
search mydomain.com
nameserver 172.x.x.x
I am suspecting is it because its querying a dns server and getting slow reply back? As far as i know, my machine is not configured at nameserver 172.x.x.x
How does /etc/resolv.conf work? Does Solaris use this file by default when querying Dns? or does it use /etc/hosts first?
I executed the following command in the korn shell:
$ variable1="qwerty" ls | sort
and the shell executed the 'ls | sort' command.
I would have expected an error message from the shell, but instead of that the shell ran the 'ls | sort' command and didn't realize the variable assignement. ... (1 Reply)
Hi there,

I have used SAR -b to get some Unix cache / buffer metrics and the results are confusing me a bit.

I'm writing a Korn script but am having trouble because the shell interprets the asterisk in this case. Can anyone tell me if there is a way to fix this so that grep takes in STDIN without the interpretation?
line="30 09 * * 1-4 /home/user01/bin/start"
echo "$line" | grep 'start' (16 Replies)

MRTG-PING-PROBE(1) General Commands Manual MRTG-PING-PROBE(1)NAME
mrtg-ping-probe - ping probe module for Multi Router Traffic Grapher
DESCRIPTION
mrtg-ping-probe is a ping probe module for MRTG 2.x. It is used to monitor the round trip time and packet loss to networked devices. MRTG
uses the output of mrtg-ping-probe to generate graphs visualizing minimum and maximum round trip times or packet loss.
mrtg-ping-probe is not run directly, but is called by MRTG as a helper when it needs to determine ping time to a host.
Act responsibly: do not use mrtg-ping-probe to ping devices without the owner's permission. Just imagine if 10,000 people decided to ping
your hosts! mrtg-ping-probe is meant to be used within your network to get round trip time performance figures for your network.
OPTIONS
To use mrtg-ping-probe you need to configure MRTG to call it from within the definition of a target host. This is done in the MRTG config
file, which is usually /etc/mrtg.conf.
Here's an example snippet: change the target name and IP address to suit your needs.
Target[your.target.ping]: `/usr/bin/mrtg-ping-probe 123.456.789.123`
SetEnv[your.target.ping]: MRTG_INT_IP="123.456.789.123" MRTG_INT_DESCR="ping"
MaxBytes[your.target.ping]: 100
AbsMax[your.target.ping]: 200
Options[your.target.ping]: gauge, growright
YLegend[your.target.ping]: ping time (ms)
ShortLegend[your.target.ping]: ms
Legend1[your.target.ping]: Maximum Round Trip Time in ms
Legend2[your.target.ping]: Minimum Round Trip Time in ms
Legend3[your.target.ping]: Maximal 5 Minute Maximum Round Trip Time in ms
Legend4[your.target.ping]: Maximal 5 Minute Minimum Round Trip Time in ms
LegendI[your.target.ping]: Max:
LegendO[your.target.ping]: Min:
Pay close attention to the backticks in the first line which tell MRTG to execute the nominated external program. Note also that you need
to use the "gauge" option, since the results of subsequent ping probes are independant values and not an incrementing counter.
