## Symptoms

- * When loading an external IoC feed through SmartConsole or the Security Gateway CLI, *$FWDIR/log/ioc_feeder.elg* shows that the feed fails with these errors:

  * "*Feed format problem. Feed format not supported*"
  * "*failed to parse"*

  <br />

* *Parsed file *feedname_custom.csv* is not created in *$FWDIR/external_ioc/**

## Cause

The system cannot parse the Linux-created `.txt` file because it uses `$` as the new line delimiter.

Running `# cat -A <filename>` shows that:

* In Linux-created `.txt` files, the new line delimiter is **$**
* In Windows-created `.txt` file, the new line delimiter is **^M$**

<br />

## Solution

Use Windows-created `.txt` files for configuring external IoC feeds.  
Alternatively, you can save the file as a `.csv` file to ensure proper parsing.
