How to find ip addresses in logfiles?
Hi guys,
I need to check a few log files as below to find out whether certain ip addresses is present on these log files.
type8code0: ls -alt
-rw-r--r-- 1 root other 796219588 Mar 20 02:25 logfile
drwxr-xr-x 2 root root 1536 Mar 20 02:00 .
-rw-r--r-- 1 root other 1854093343 Mar 20 02:00 logfile.hour02
-rw-r--r-- 1 root other 366729263 Mar 20 01:00 logfile.hour01
-rw-r--r-- 1 root other 9001399293 Mar 20 00:47 logfile.20.Z
-rw-r--r-- 1 root other 8267721901 Mar 19 00:45 logfile.19.Z
-rw-r--r-- 1 root other 7498682761 Mar 18 00:39 logfile.18.Z
-rw-r--r-- 1 root other 6196926607 Mar 17 00:31 logfile.17.Z
-rw-r--r-- 1 root other 4794493570 Mar 16 00:23 logfile.16.Z
I've saved the list of ip addresses in “iplist” file.
cat iplist
10.10.10.10
10.10.10.11
10.10.10.12
10.10.10.13
10.10.10.14
What is the best command to do this?
This is what I do now, but it takes sometime. Hopefully there is easy way to do this.
grep 10.10.10.10 logfile > output_logfile_10.10.10.10
grep 10.10.10.11 logfile > output_ logfile_10.10.10.11
and so on
zcat logfile.16.Z | grep 10.10.10.10 > output_logfile.16.Z_10.10.10.10
zcat logfile.16.Z | grep 10.10.10.11 > output_logfile.16.Z_10.10.10.11
and so on
Thanks

atsadc
ATSADC(1) local ATSADC(1)
NAME
atsadc, atsa1, atsaftp, atsahttp -- counter-collection
SYNOPSIS
atsadc [ t n ] [ ofile ]
atsa1 [ t n ]
atsaftp
atsahttp
DESCRIPTION
System activity-data can be gathered on special request of a user [see atsar(1) ] or automatically, on a routine basis, as described here.
Usually the kernel maintains statistical counters that are incremented as various system actions occur. These include counters for CPU uti-
lization, disk utilization, memory utilization and various network statistics.
The program atsadc and the shell-script atsa1 are used to collect, save, and process these counters.
The program atsadc (the data collector) samples system data n times with an interval of t seconds between samples, and writes in binary
format to ofile or (default) to standard output. The sampling interval t should be greater than 1 second. If t and n are omitted, a special
reset-record is written. This facility is used when booting to a multi-user state, to mark the time at which the counters restart from
zero. For example, the reset-mark can be added to the daily data by the command:
/usr/local/bin/atsadc /var/log/atsar/atsa`date +%d`
Note that this entry is written to the /etc/rc.d/init.d/atsar file.
The shell-script atsa1 is used to collect and store data in the binary file /var/log/atsar/atsadd where dd is the current day of the month.
The arguments t and n cause records to be written n times at an interval of t seconds, or once if omitted. Furthermore this script takes
care that log-files older than a week are removed once a day.
A file containing following entries should be added to the /etc/cron.d directory to produce records every 20 minutes during working hours
and hourly otherwise:
0 * * * 0-6 root /usr/local/bin/atsa1
20,40 8-17 * * 1-5 root /usr/local/bin/atsa1
See crontab(1) for details.
The shell-script atsaftp counts the new transfers registered in the FTP-logfile(s) since the previous time this script was activated; the
new counters are stored in the /var/log/atsar/ftpstat file in ASCII-format. The names of the FTP-logfiles to be watched are specified in
the /etc/atsar.conf configuration-file.
The shell-script atsahttp counts the new transfers registered in the HTTP-logfile(s) since the previous time this script was activated; the
new counters are stored in the /var/log/atsar/httpstat file in ASCII-format. The names of the HTTP-logfiles to be watched are specified in
the /etc/atsar.conf configuration-file.
Both scripts must be activated just before the program atsadc is started, which also collects these counters.
FILES
/var/log/atsar/atsadd
Daily data file, where dd are digits representing the day of the month.
