I'm trying to track down an elusive issue where a particular URL refuses to work. My investigations so far suggests there's some kind of DPI firewall/proxy/whatever between the client and server that looks at the path of the request and refuses based on that, and I'd like to known where that one is so I know who to contact to resolve the issue. In short

curl http://server/path   # FAILS with HTTP 401 Access Denied
curl https://server/path  # WORKS
(client on another network)# curl http://server/path  # WORKS
curl http://server/another_path # WORKS

So I'm wondering if there is some kind of traceroute-like tool that would work with HTTP. Basic traceroute doesn't work, because I can't tell traceroute to send a well-formed HTTP request with the particular path that is causing problems. I found https://github.com/watson/http-traceroute but that tracks only HTTP redirects, and doesn't help with this particular issue. Any ideas?

EDIT No, the server is not managed by me. It's a publicly accessible server managed by another organization entirely.

We recreated a fileserver, which had an XFS filesystem using project quotas residing on a SAN. Unfortunately, we had forgotten to backup /etc/projects and /etc/projid on the server before reinstalling. The XFS filesystem itself, and the quota information stored therein, is all Ok AFAICS. Is there some way of figuring out the project ID's of the directories on disk, so that we can recreate /etc/{projects,projid}?

To clarify, lets say the XFS filesystem is mounted on /export/xfs and contains directories /export/xfs/foo and /export/xfs/bar. So we need to have the following entries in /etc/projects

NN:/export/xfs/foo
MM:/export/xfs/bar

and the following entries in /etc/projid

foo:NN
bar:MM

So how do we retrieve the values of NN and MM, which are stored on disk?
