How do I enable telnet or rsh on my NetMAX machine?
Applies to: NetMAX 4.0x
address-suppressed
Telnet as well as rsh have been disabled on NetMAX version 4.0x. We recommend that customers use ssh as a replacment. Its much more secure and nearly always a better alternative. We recommend PuTTY for use as a Windows client, as its free and reliable.

However, if you wish to enable telnet or rsh and are aware of the ramifications, follow these steps:

  1. For telnet, edit the file: /etc/xinetd.d/telnet
  2. For rsh, edit the file: /etc/xinet.d/rsh
  3. Change "disable = yes" to "disable = no"
  4. Restart xinet.d. This is most easily done by going to Services->FTP, and without changing anything, choose Store, then choose Commit.

Note that this change may get overwritten during future NetMAX updates. In that case, you will need to repeat this process after the update.

Are USB keyboards compatible with NetMAX?
Applies to: NetMAX 4.0x
address-suppressed
Generally, the answer to this is No. However, many computers will power the USB keyboard through the BIOS, allowing you to use the keyboard to install NetMAX. The keyboard will then fail to work when running NetMAX after the initial install. Since it is still possible to administer the NetMAX machine through the web interface and also to use ssh to get to the console, it should be possible to use a NetMAX machine in this way.

If you need to get in to the NetMAX machine directly, then make sure you have a PS-2 keyboard, and a computer that supports it.

How do I set up a catch-all mail alias?
Applies to: NetMAX 3.x - 4.0x
address-suppressed

Explanation of a Catch-All Alias

Creating a "catch-all" alias will get all mail for e-mail addresses that are not already defined as aliases. Therefore, it will send all mail to the alias, except for addresses that are already defined as aliases.

For example, lets say you have this setup:
  • Users:
    • jeff
    • bill
    • fred
  • Aliases:
    • support (goes to jeff)
    • help (goes to bill and fred)

Now, if you were to create a "catch-all" alias, all messages would go to that alias except for mail to support and help.

Let's say you didn't want mail to jeff, bill, and fred to go to the catch-all alias either. Then you would set it up like this:
  • Users:
    • jeff
    • bill
    • fred
  • Aliases:
    • jeff (goes to jeff)
    • bill (goes to bill)
    • fred (goes to fred)
    • support (goes to jeff)
    • help (goes to bill and fred)

Now, when you create the catch-all, it will skip all those aliases, so it will only catch the mail destined for somebody besides them. Since all your users also have aliases defined for them, they will continue getting mail as normal.


How to Create a Catch-All Alias

To create a catch-all alias for a domain, go to Home|Services|Mail|Aliases|Create. Leave the Alias field blank and select the domain. Enter one or more addresses that will receive mail for the catch-all account. When you are done, hit Return. Now, do a Store and Commit, and the catch-all alias will begin working.


Caveats to setting up a Catch-All Alias

There are two problems with catch-all accounts. These are not due to NetMAX's implementation, but the nature of this type of account on a standard Linux system.

Since the account will be catching ALL mail that is directed to the domain, it will catch a great deal of mail that isn't useful. This will be mostly comprised of spam, which is being sent in increasing amount every day. Many spammers don't verify accounts before sending mail to them. By accepting all mail to the domain, you will be getting a much larger amount of spam. This places a large burden on your computer as it needs to process all that mail. It also can quickly fill up your storage space if you aren't proactive about getting rid of it. There is also the issue of taking the time to deal with all the extra mail.

The second possible problem with Catch-All accounts was stated above, though not so explicitly. That is, it will override all system accounts. The instructions above explain how to overcome this by creating an alias for each user. Its important to note it as a problem, even though it does have a work around, however. Creating a catch all account without knowing the implications can have the consequence of users no longer receiving their e-mail otherwise.

I manually saved my configuration by backing up /var/conf. How do I properly restore it?
Applies to: NetMAX version 4.0x
address-suppressed
If you backed up your /var/conf data, and need to restore it, there is a special procedure to ensure that your configuration is restored properly. Follow these steps to get your configuration back:
  1. Move all files in the /var/conf directory to a temporary backup directory.
  2. Restore /var/conf from your backup into the now empty /var/conf directory. The method of restoring will vary depending on whether you backed up to tape or to a floppy.
  3. Make sure you are logged in as root at the command line.
  4. Type:
    find /var/conf/sdb -type f -exec touch {} \;
  5. Next, type:
    parse pmake commit

How do I register and activate my NetMAX Software?
Applies to: NetMAX version 4.0x and Add-ons
address-suppressed
When you first install NetMAX, you will be asked for a license number. This license number will have been provided to you via e-mail or on a colored sheet of paper.

After installing, you will then need to register your product. Registering is required for activating your product. If the product is not activated in 90 days, you will no longer be able to administer your NetMAX through the interface.

Please follow these steps for registering and activating your product:
  1. Navigate to: https://www.netmax.com/order/support/support.cgi
  2. Click on the link to create a new user if you have never done so before.
  3. Fill out the form with your information and your product's information.
  4. The license number will be that which you received when you purchased your product.
  5. The activation key can be found in the NetMAX interface. Log in to the Interface, and navigate to Home|System|License Management. The eight character activation key will be located at the bottom of the "Currently Installed License Numbers" frame.
  6. Keep this screen in NetMAX open for the final step of the activation process.
  7. Double check your e-mail address to ensure that it is entered correctly, and click the register button.
  8. The registration activation code will then be sent to the e-mail address you specified.
  9. On the License Management screen of the NetMAX Interface, click the pencil in front of the product you are activating.
  10. Enter the Registration Activation Code from your e-mail into the blank spot in the table.
  11. If you have multiple products, log in to the support database with your new account. Use the "Create Product" button to repeat this process for all your products.
  12. When all products have been registered and have their registration activation codes entered, click on the Approve button in the NetMAX Interface.
  13. Click on the Commit All button, and wait for the status bars to finish. When this process is complete, your NetMAX will be ready to go.

I upgraded to NetMAX 4.04 and my SCSI RAID controller (or Wireless Card) stopped working. How can I fix this?
There is a bug in NetMAX 4.04 where certain SCSI controllers will not work. If you encounter this bug, there is an easy fix for it. You need to remove the Devs.first file. Follow these steps:

  1. Log in to the NetMAX Interface as the administrative user.
  2. In the Files Manager, navigate to the /usr/netmax/etc/rc.d directory. Click on root to begin navigating there.
  3. Remove the Devs.first file by placing a check in the box, clicking on Actions, and choosing to "Delete" the file.

Please note: It has been shown that this bug can also affect Wireless Network card functionality. If your wlanX device gets changed to "Unknown Ethernet" in the interface, then follow the above steps to fix this problem.

I'm having problems viewing the NetMAX 4.0x interface with Internet Explorer®. How can I fix this?
Applies to:  NetMAX version 4.0x
address-suppressed
There are a variety of problems that can come up when using certain versions of Internet Explorer to view the NetMAX interface. The most common problems are frequent security warnings, and a doubling or nesting of the web page. These problems are due to a problem with Microsoft's implementation of SSL 3.0. If you are experiencing these problems, or other problems that seem related to your web browser, follow these instructions.

The first thing we recommend is using an alternate browser. We have had great success with both Mozilla and Netscape. We actually list these two browsers as a system requirement because of this.

If you are determined to use Internet Explorer, then turn off SSL 3.0. This is done by unchecking Tools -> Internet Options -> Advanced -> Use SSL 3.0.

Note that turning off SSL 3.0 in Internet Explorer may clear up most of these problems, but you may still experience problems with it. We have found that the best performance (quickest page loading times and fewest errors) is obtained with Mozilla.

How do I implement Proxy ARP on my NetMAX machine?
Applies to: NetMAX 4.0x
address-suppressed
One of our more frequent questions in the NetMAX Support Department is how to implement Proxy ARP for Bridging network interfaces. If you have more than 1 static IP address in the same subnet, and want to use a NetMAX machine to route the addresses to other machines on your network, Proxy ARP is the way to go. The NetMAX configuration steps are below, however please note that your ISP will need to know the IP address of your NetMAX machine and that it will be routing the rest of your IP addresses. They can then set up the routing tables on their routers, allowing you to configure your NetMAX for bridging.

  1. First make sure your NetMAX is properly configured to be on the internet. Test this by pinging some web sites with the NetMAX.
  2. Under Network->Machines, add a machine for the computer that you will be routing traffic to. Specify the IP address that you want to assign it, and make sure to fill in the MAC address (or Hardware Address). This final step is the most important, as Proxy ARP will rely on this when routing traffic.
  3. Next, go to Network->Machine Groups, add a new group to use for Proxy ARP. Add the machine that you created in step 2 to this group.
  4. Navigate to Network->Routing->Bridge. This is where you will turn on bridging via Proxy ARP.
  5. For Proxy on Ethernet, choose your external network interface. This interface will be the one configured with an IP address and connected to your internet provider.
  6. The Physical Ethernet for Machines will be the network interface connected to your internal switch. All machines you are proxy arping for should also be connected to this switch.
  7. Choose the Machine Group you created during step 3 next. Add this entry, Store, and Commit the changes.
  8. Create firewall rules to allow the forwarding of traffic between the external interface and your proxy arped machine group. You will need forwarding rules on both the external interface as well as the interface the other machines are physically connected to.
  9. On machines you are Proxy Arping for, set their IP addresses to be what you specified for them when creating the Machine entry in the NetMAX interface.
  10. Set the default router for the machines being proxy arped to be the IP address of the external interface of the NetMAX machine. You should now be ready for testing.

How do I change the IP address(es) on my NetMAX machine?
Applies to: NetMAX 4.0x and later
address-suppressed
If you are changing one IP address to another in the same subnet, simply go to Network->Interfaces->Edit Interface, manually change the address, and do a Commit.

If you are changing multiple IP addresses on an interface, or changing to an IP on a different subnet, you will need to follow these steps. Due to many input validity checks (for safety), its not possible to just change the address outright.

  1. Go to Network->Interfaces->Edit Interface
  2. Change the NetMAX to 128.0.0.0 and click Store
  3. Click the Edit button to return to the Edit Interface screen
  4. Add the new IP addresses to the list of IPs and click Store
  5. Go to Network-Routing
  6. Change the IP address of your default router to its new value and click Store
  7. If your DNS servers are also changing, then navigate to Network->DNS
  8. Change the DNS IP addresses to their new values and click Store
  9. Go to Network->Domains
  10. Change the IP ranges on your domains to the new IP range and click Store
  11. Go to Network->Naming
  12. Change the IP addresses associated with your hostnames to their new IP addresses and click Store
  13. Go back to Network->Interfaces->Edit Interface
  14. Remove your old IP addresses
  15. Change your netmask back to its correct value
  16. Store and Commit the changes
  17. Physically plug your NetMAX into the new device (cable modem, router, etc...) if necessary
  18. After waiting an appropriate amount of time (a few minutes), log into the NetMAX interface and test that everything is working properly
  19. If you are still having problems, give us a call and we'd be happy to help out.

What happens when I click "Send" in my mail client?
Have you ever wondered what happens when you finish an email message and click "Send?"
This article is a brief and general discussion on the subject
"Where does the mail go?"

Basically, it works in much the same way as real-world mail:
  1. The local SMTP receives outbound messages.
  2. The destination address is analyzed.
  3. The SMTP server checks for the DNS mail exchanger (MX) record of the domain in the destination address. This points to to SMTP server that handles inbound messages for the destination email address.
  4. The message is sent to the destination SMTP server.
  5. If there is a problem, either the SMTP will hold on to the message and try to retransmit later, or it will bounce and a bounce notification will be send to the originator of the message.
  6. If there are no problems, the SMTP server will usually pass the message off to a special program called the "delivery agent."
  7. The delivery agent's ultimate goal is to get the message into the mailbox of the recipient. Sometimes, however, the delivery agent will perform other steps like content-filtering or auto-responding, which may involve passing the message to other programs before final delivery.
