IMAP App Troubleshooting - Linux/Splunk checking IMAP on Exchange 2007

pstraw

Sharing my experiences with the getting IMAP App (Linux/Splunk) to check an IMAP mailbox hosted on Microsoft Exchange 2007. Hope it helps.

Example imap.conf Configuration;

cat /opt/splunk/etc/apps/imap/local/imap.conf

[IMAP Configuration]
debug = True
deleteWhenDone = False
disabled = 0
fullHeaders = False
includeBody = True
mimeTypes = text/plain
folders = Inbox, Inbox\Subfolder
noCache = False
server = 11.22.33.44
useSSL = False
user = erroremails@company.com
xpassword = U2FsdGVkX118jLJ2rc1fCJT4VY1KzOcWuTHxQ18kIOdDrcQ=
splunkuser = admin
splunkxpassword = U2FsdGV1kX119umt1wLRrUP1tRk4es3jiuiF587D16+jCTQ=
splunkHostPath = https://localhost:8089

Environment;

  • Splunk Server -- Ubuntu 10.04.1 LTS x86_64 -- Kernel 2.6.32-24 -- Splunk 4.1.5
  • IMAP Server -- Windows Server 2008 x86_64 -- Exchange 2007 SP2 U4

HOWTO Generate Encrypted Passwords;

bash /opt/splunk/etc/apps/imap/bin/genpass.sh
Enter the password you want to encrypt:

copy/paste the output to the appropriate variable in imap.conf

Execute getimap.py --debug

cd /opt/splunk/etc/apps/imap
python bin/getimap.py --debug

Error: Environment variable SPLUNK_HOME must be set

Traceback (most recent call last):
File "bin/getimap.py", line 39, in <module>
raise ConfigError('Environment variable SPLUNK_HOME must be set')
__main__.ConfigError: Environment variable SPLUNK_HOME must be set

Solution credits to gkanapathy

source /opt/splunk/bin/setSplunkEnv 
echo $SPLUNK_HOME

Note: These environment variables help get the getimap.py to run from the CLI. They are not required for Splunkd or SplunkWeb.

Ensure imap.conf is Interpreted Properly

Debug again. Pay close attention to all of the True/False values. Ensure they are obeying your local/imap.conf settings. Try using "True" or "False" instead of 0 or 1.

cd /opt/splunk/etc/apps/imap

ImportError: No module named splunk.auth

Reason: Running "python" from the CLI is using your system's native python install, which doesn't include Splunk specific modules.

which python

Solution 1.

/opt/splunk/bin/python bin/getimap.py --debug

Solution 2. credits to gkanapathy

A quick way to set the right environments, paths, etc. to work as a script running inside Splunk is to use "/opt/splunk/bin/splunk cmd "

/opt/splunk/bin/splunk cmd python bin/imap.py

Error: libxslt.so.1: cannot open shared object file: No such file or directory

    import splunk.auth as au
  File "/opt/splunk/lib/python2.6/site-packages/splunk/auth.py", line 1, in <module>
    import splunk, rest, util

    import lxml.etree as et
ImportError: libxslt.so.1: cannot open shared object file: No such file or directory

Solution for Ubuntu 10.04 to install the missing library;

apt-get install python-lxml

The following NEW packages will be installed:
libxslt1.1 python-lxml

Error: KeyError: 'SPLUNK_DB'

DEBUG:root:'SPLUNK_DB'
Traceback (most recent call last):

  File "/opt/splunk/lib/python2.6/UserDict.py", line 22, in __getitem__
    raise KeyError(key)
KeyError: 'SPLUNK_DB'

Solution is tied to the environment variables being set properly. Use setSplunkEnv;

source /opt/splunk/bin/setSplunkEnv 
echo $SPLUNK_DB

A quick way to set the right environments, paths, etc. to work as a script running inside Splunk is to use /opt/splunk/bin/splunk cmd <command>, e.g. /opt/splunk/bin/splunk cmd python bin/imap.py. Pretty much that is what the command is intended for. You could also source /opt/splunk/bin/setSplunkEnv into your shell.
