Recently Marco Shaw posted a little nntp-stats script in the newsgroup that I thought was pretty neato, and right up my alley since we were in the middle of adding get-nntp and send-nntp cmdlets to the /n software NetCmdlets product. So as a tip of the hat to Marco, here is my version.

Poster Stats:

Get-nntp returns a collection of objects containing the subject, articleid, sender, references, etc of articles posted in a particular newsgroup. I put together a few lines of code that uses get-nntp to create a hashtable of people who have posted in the PowerShell newsgroup and how many times.

## usage: nntpstats [-server] <string> [-newsgroup] <string> [-count] <int> ## param( [int] $count = "100", [string] $server = "", [string] $newsgroup = "" )
$articles = get-nntp -server $server -newsgroup $newsgroup -list $count $myhash = @{} for($counter = 0; $counter -lt $articles.Length; $counter++) { if (! $myhash.Contains($articles[$counter].FromName)) { $myhash.add($articles[$counter].FromName, 1) } else { $myhash[$articles[$counter].FromName] = $myhash[$articles[$counter].FromName] + 1 } }
$myhash.GetEnumerator() | sort Value -descending

I'll give this a run with a count parameter value of 2 so that I can easily show the actual article data returned by get-nntp itself. Below you can see the output of my call to the nntpstats script with count = 2, just two posters, each with 1 post.

PS C:\> . .\nntpstats -count 2                         
Name                           Value

Marco Shaw                     1

PS C:\>


I can tweak this script to give me a list of messages that match a particular search criteria. Unfortunately most NNTP servers don't implement the search capabilities that are specified in the NNTP RFC's, so implementing such a search requires retrieving and searching article bodies manually:

## usage: nntpsearch [-server] <string> [-newsgroup] <string> [-count] <int> [-searchterm] <string> ## param( [int] $count = "100", [string] $server = "", [string] $newsgroup = "", [string] $searchterm = "Lance" )
$articles = get-nntp -server $server -newsgroup $newsgroup -list $count for($counter = 0; $counter -lt $articles.Length; $counter++) { $article = get-nntp -server $server -newsgroup $newsgroup -view $articles[$counter].Number if ($article.Message.Contains($searchterm) -eq "true") { Write-Host $article.MessageID } }
