Forums: SplunkAdministration: Problem to Index Linux Auditd

Hi everyone.

I have some problems to get full index some linux audit log.
I set a light forwarder server to report they /var/log/audit/audit.log to the central server.

The forwarder show in the log file the normal lines
example /var/log/audit/audit.log

type=PATH msg=audit(1255538594.639:261): name="/etc/file6" flags=310 inode=473281 dev=fd:00 mode=040755 ouid=0 ogid=0 rdev=00:00
type=CWD msg=audit(1255538594.639:261): cwd="/root"
type=FS_INODE msg=audit(1255538594.639:261): inode=473281 inode_uid=0 inode_gid=0 inode_dev=fd:00 inode_rdev=00:00
type=FS_WATCH msg=audit(1255538594.639:261): watch_inode=473281 watch="etc" filterkey=etc perm=2 perm_mask=3
type=SYSCALL msg=audit(1255538594.639:261): arch=40000003 syscall=5 success=yes exit=3 a0=bff6fc4b a1=8941 a2=1b6 a3=8941 items=1 pid=16375 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 comm="touch" exe="/bin/touch"

but the Central Splunk just show me 3 of 5 lines.

type=CWD msg=audit(1255538594.639:261): cwd="/root"
type=FS_WATCH msg=audit(1255538594.639:261): watch_inode=473281 watch="etc" filterkey=etc perm=2 perm_mask=3
type=SYSCALL msg=audit(1255538594.639:261): arch=40000003 syscall=5 success=yes exit=3 a0=bff6fc4b a1=8941 a2=1b6 a3=8941 items=1 pid=16375 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 comm="touch" exe="/bin/touch"

I don't know what to touch to allow to index the full log and not partially. BTW When I index a off line file as /var/log/audit/audit.1.log show me all the content.

my best regards for any help on this one.

What does your inputs.conf look like on the forwarder?

Please tell me the path of the inputs.conf

the /opt/splunk/etc/system/local/inputs.conf

[default]
host = centos4

1. default cipher suites that splunk allows. Change this if you wish to increase the security
2. of SSL connections, or to lower it if you having trouble connecting to splunk.

cipherSuite = ALL:!aNULL:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM

I'm looking for the inputs.conf that tells the forwarder which files to monitor, but I wouldn't worry about that at the moment.

What search are you running on the indexer that shows you only 3 of 5 lines? What is the time picker set to? If you want, you can upload a screenshot to www.imagebin.ca and post the link to it here.

Araitz. I resolved the problem.
I configured my inputs.conf in the Apps

"opt/splunk/etc/apps/search/local/inputs.conf"

I added the index parameters to indicate what index has to go the data.
I think the problem was the splunk started using the main index by default and auto set the sourcetype=linux_auditt

Now It's indexing on the OS index and using the sourcetype=audit.log and show all the events or at least the most important.

thanks for your help.

Great to hear!

can you post you inputs.conf - I'm having similar issues - I can forward data from my splunklightforwarder to a port on the indexer but it's not going to the index i set in the inputs.conf using

[monitor:///usr/local/apache2/logs/]
apache logs /usr/local/apache2/logs/
index = devidx
disabled = false
host = devhost

I can view the data in the main index but not my devidx

Have you
* created the new index on the indexer
* set your user role to be allowed and/or to default to search the new index?
