OpenNMS

Make sure you run Yum update and then do rpm --import http://yum.opennms.org/OPENNMS-GPG-KEY to reimport the key.

didn't run when I attempted to use it. Nor was emac

[root@localhost data]# nano pg_hba.conf
-bash: nano: command not found
[root@localhost data]# emac pg_hba.conf
-bash: emac: command not found

I'm assuming vi works no problem though.

vi is the one text editor that exists in "every" UNIX system. It's the editor you always have, no matter what. Only one you need to know because it is the only one you know you'll always have.

Vi is a text editor, sometimes also called vim. It'd just be:

vi pg_hba.conf

Press i to make edits and when done, press Esc and :wq followed by enter.

Thank you.

It's slow - but It's running, and I'm connected.

Most any network monitor will be slow, without beefy hardware to back it up. They are quiet resource intensive.

Nothing wrong with using nano either. I have never had an issue caused by nano.

I know how to use vi, but I don't use it.

By posting the log file here, i'm hoping to see something different. I"m not accustom to this type of log file... so I am unsure what to look for.

scottalanmiller

That's where the log stops?

Yes- unless I'm doing something incorrectly. Even the attempt last night and review of the log shows this. However since I am new to using vi and looking at logs on the Linux system using the CLI,.. I might see about downloading it locally and going from there... There is a high chance I am not seeing the complete log.

You can use the cat command to view files. Tail will allow you to only see certian lines of a log file as well.
