Admin Account

An administrative account called 'admin' has been added that allows you to carry out some of the common tasks on the system. This account is almost as powerful as root so access to it should be restricted to responsible staff.

To access the administrative menu you should login as 'admin' the initial password as been set to 'admin' and it is recommended this is changed as soon as possible.

This guide will cover all the options that are available. When using the Admin menus <tab> will allow you to jump between the options and the option at the bottom of the box.

The initial menu contains the following options:

Create Recovery Disks

This will start up the Edge 're2' menu to allow you to generate recovery disks for your system. Full details are contained in the Microlite BackupEdge manual. There are also some FAQ's in 'Support Documents and FAQ' section of the on-line help.

Backup menu

Will access the BackupEdge menu to allow manual backups, backup schedules, backup status etc. See the Edge manual for details.

Cross Updating Menu

Access to 'xmenu' the cross updating menu - details are available via the on-line help.

Shutdown the system

Will shutdown the system. You will be asked for confirmation.

Administration Menu

Common Administration task - will be explained in detail below.

Enserve Control menu

If you have the EnServe module installed this menu allows you to alter the configuration and will be explained later in this document and via the 'Enserve' section of the on-line help.

Administrative Menu

This menu contains the common tasks:

Kill a user or Terminal

If you need to kill a user or reset a hung screen you can do so with this option. When selected you will get a list of all the users on system. Press Return to continue and you will be asked to enter either the name of user to kill OR the tty number.

The system will display what it is about to do and give you the option to abort by pressing the <DEL>ete key.

---

Add a user to the System

As the option suggests, this will add a user to both Unix and (optionally) Premvet.

You will be asked for the login name (8 characters max) and if the user already exists you will be warned.

Login name :

Once a login name is set it cannot be changed without removing the person completely.

You will then be asked for the users full name e.g. Login name may be tom and full name T.W. Melvin. When the user 1st logs in they will be asked to set their Unix password (can be changed later from within Premvet).

Full name :

You will then be asked if you want them added to Premvet, answer accordingly. You will be prompted for the Premvet 3 character ID. They will be added under premvet group 1 and take whatever access permissions you have allocated to that group.

In addition, a Windows home directory will be created ($HOME/smbhome) and a personal web folder created ($HOME/public_html) with the appropriate Unix access permissions applied. If you have Samba installed the user will have a blank SMB password allocated and can be changed on the user setup screen from within Premvet.

---

Reset the Modem

If the modem appears hung this option will reset the modem. If there is a user currently using it you will have the option to kill them.

---

Reset a Users Password

If a user has forgotten their Unix password this option can be used to reset it and they will be asked for a new password the next time they login. This option should also be used to reset the 'admin' account periodically.

You will be presented with a list of all users e.g.:

Select the user and their password will be reset e.g.:

When they next login they will be prompted for a new password.

Please do not leave it too long until the user logs in sets a password. Accounts with no passwords are a security risk.

---

Edit System Files

There are some system files you may wish to make changes to and the common ones can be changed via this option. Please note the editor used WILL BE the system editor 'vi' - this is intentional as there are times where you require the functionality of vi to ensure the changes are made correctly. There are guides to using 'vi' in the FAQ section of the on-line help.

Some of the options relate to EnServe and may do nothing on your system.

The files you can alter are:



Aliases	Controls what Mail Aliases are in use.
Scanner	What folders are automatically Virus Scanned.
Hosts	IP address to name mapping file. All network devices should be listed in this file.
Mutt	Mailer Setup and Configuration
Resolv	What Nameservers you are using. It is not necessary to edit this file normally.
BlackList	List of mail addresses that are Blocked.
Premvet	The start-up file used by Premvet. Controls what global options should be applied. You can also set Lab E-Mail settings.
Crontab	Cron is the schedular that controls what tasks run when. ***Need URL HERE*****

View System Log files

As the option suggests, this lets you look at some of the log files used by the system. These include Web access, FTP usage, Syslog, who has logged on recently, the current processes and network usage.

Most of the options are self explanatory with the exception of the IPF log.
IPF - this is the firewall used when Enserve is in-use. This option will scan the current firewall log files, split out each 'service' and then run a detailed report on it. As it is a detailed report it can take a little while to run (depends on the size of the log file).

Once the system has split up the log you will be asked to enter the specific serve to look at:

(Use the <Tab> Key and the <SpaceBar> to select)

Here we have selected the pop3 log

Then the report will be displayed (use PageUp/Down and Arrow Keys to navigate).

---

View Premvet Logfiles

Similar to the System log viewer above except it looks at the log files maintained by Premvet. These include Diary cancellations, when animals were added, User activity, Vatbook resets, edits made to the clinical file and who is currently using Premvet.


Added	Dates/Times when animals were added.
Diary	Diary Cancellations
User	If user logging on this will show all activity.
UUCP	Last Cross Updating Integration information
Vatbook	Vatbook resets
Edit	Clinical edits - Dates and times and who
Who	List the current Premvet users.

Tip: The slash key (/) can be used to search any of the log files

---

Show Password/Login Status

Access to the system statistics dealing with Terminal activity, login times and password expiry times. These reports are discussed fully in the Unix on-line help.

---

Set the System Time

If your system clock goes adrift it can be reset in one of two ways:
• If you are connected to the net you can tell the system to synchronise with a known time server
• Manually enter the correct data and time.

Select as required - remember to avoid using the manual option when there are active users on the system.

---

Remove Premvet Locks

There are some files created to ensure that only one person can carry out a specific task (lock files). Normally the system will remove the lock as soon as the task is finished. If there is a rogue process, modem line droped un expectedly, system problem etc. the lock can be left on thus not allowing other users access. This option will remove them. There is NO check as to whether it is valid or not - it will be simply removed.

---

Scan for Viruses

You do need a virus scanner installed for this option to do anything. You have the choice of what to scan - selcted with the <SpaceBar>


More details are in the EnServe Documentation



EnServe Control menu

If you have the EnServe module installed this option allows access to some of the EnServe specific options. It currently has:



TCP Wrappers

Which sites can/cannot access the server

JunkBuster

Privicy Control and Ad blocker.

Squid Proxy Server

The Web Proxy server, you can add ACL's here to restrict times and which PC's can access the web. See the EnServe FAQ on restricting access.

IP Filters

A second lever of security that can restrict access based on the service they are trying to use.

Spam Assassin

E-Mail filter rules to mark mail as containing Spam.

Security Report

A report that scan the log files showing you which sites have been attempting to access the system, which have succeeded and what web sites staff have been accessing.

This report is explained in details in the EnServe FAQ's.

Virus Definition Files

If you are using McAfee as a virus scanner this option will update your definition files on-line.

Mail Settings

The configuration for Exim (MTA).

Samba Configuration

The configuration for the SMB server in use. Full Samba Manual

Lookup a name/IP

This utility is handy to see who an address or domain belongs to in real-life. Often, you will see a 'site' attempting to access your system - who is it? who do you complain to?

You will be prompted for 'Who To Find' - enter what information you have. You may need to run the option a few times, once to translate the IP number to an address - then enter the address to locate the domain and then try the domain.

Not all IP Numbers will resolve to addresses!!
