Question How to mount a directory on one server to another?
Question 1) I have directory /home/userme/reports on server 1 and I want to mount that directory anywhere on server 2. How do I make this happen?

Question 2) Server 2 is behind a firewall and server 1 is public...by mounting server 1 on server 2 do I compromise the security of server 2?

Answer 1: Use your choice of NFS, SMB (Samba) or WebDAV
Answer 2: Yes and No. If someone breaks into your public server, he could read those files, or maybe even write it (be sure to export that path as read-only). If you're using a system user for mounting, he might get that users uid/password combination. However, if you set it up right (read-only access, unprivileged user, unprivileged information in the files, no login from outside to the inside) it should be rather safe.

I was hoping for an answer for dummies Smilie What do I need to do to export the /home/userme/reports dir on server 1?

From what you said I am guessing the steps here...

1)Create a user with no privleges on server 1 (where dir will be mounted)
This will be the owner of the mounted volume

2)Export dir from server 2 via cmd >export dir

3)Mount dir via cmd >mount -t nfs ipaddress.server2:dir

4)Change owner of mounted volume to newly created user from step 1

Is this right?

If you're going with NFS you'll have to do
  1. Install an NFS server for your OS
  2. Tell the NFS server which directories to export by entering them into /etc/exports. Example:
    Code:
    /home/userme/reports 10.0.0.2(ro,all_squash,anonuid=<uid>,anongid=<gid>)

    This tells NFS to export /home/userme/reports to the server with the IP 10.0.0.2 as read-only, and all users are mapped to the anonymous user, using a certain UID and GID.
  3. Open/redirect the port 2049 (and maybe 111 if you're using portmap) on the firewall for the internal server for the public ONLY
  4. On the public server run mount -t nfs internal_server:/home/userme/reports /mnt/reports
This should get you set up.
