| Real-time network connection monitoring |
New |
Monitoring of real-time traffic flows through any NetBox network
interface is now possible. This allows you to answer the eternal question,
"why is my link running slowly?", and is invaluable in debugging
a variety of network related problems. It is possible monitor multiple interfaces
simultaneously. To access this feature go to Administration | connection
monitoring in the NetBox web interface. |
| New DHCP options screen |
New |
Custom DHCP options for the NetBox DHCP server can now be
configured. These can be set under Configuration | Advanced LAN by
selecting a particular LAN interface and then clicking Edit in the
Custom DHCP Options field. This screen includes most standard DHCP
options. If required, more options can be added under Configuration |
Advanced LAN | Modify DHCP Option Fields. |
| Automatic DHCP lease culling |
New |
The NetBox will now automatically remove old DHCP leases if
the number of available leases is running low. This culling process occurs
daily. The culling threshold can be configured under Configuration |
Advanced | DHCP server lease culling threshold in the NetBox web interface. |
| Update expiry date display |
New |
The date that firmware updates are due to expire for a particular
NetBox are now shown on the home screen of the web interface. A warning
is shown if updates have expired. |
| Active PPTP user display |
New |
Usernames and data statistics for active logins to the NetBox
PPTP server are now shown under Administration | active remote VPNs
in the web interface. |
| Email Monitoring purge |
New |
Email Monitoring records can now be manually purged. See
Email Monitoring | config in the web interface. |
| MTU option for ethernet connections |
New |
The Maximum Transfer Unit (MTU) of ethernet based Internet
connections can now be manually set. This option is found under Configuration
| Connection | MTU in the web interface. |
| Cross site scripting filtering in webmail and webmail enhancements |
Enhancement |
Extensive filtering of emails has been put in place to eliminate
potential cross-site
scripting issues with the NetBoxes webmail feature. Additionally, the
display of HTML emails through the webmail feature has been greatly improved,
making most emails far more readable. |
| Improved Network Monitoring interface statistics screen |
Enhancement |
The Network Monitoring interfaces screen is now much quicker
in responding to user queries. Additionally, PPTP interfaces are now shown
by the user who logged in. See the difference at Network Monitoring |
interfaces. |
| Improved email queue screen |
Enhancement |
The NetBox email queue screen has been improved. By default only the
first 15 queue entries are now displayed to avoid large outputs when the
queue is large (this can be changed). Additionally, clearing of the queue
now requires an extra confirmation step and the screen has been generally
improved asthetically.
|
| Netlog processing time display |
Enhancement |
During periods of high network load the Network Monitoring
feature will develop a backlog of data to process. This can mean that the
data displayed with Network Monitoring may not be real-time. To view the
time of the currently processed Network Monitoring data you can now go to
Network Monitoring | config in the web interface. |
| TCP based connection tests |
Enhancement |
The NetBox checks link integrity once per minute by performing
a network test against various test hosts. This was done by using ICMP 'ping'
packets, however several ISPs have now disabled pings in response to the
latest worm attacks. The NetBox now uses a TCP based method to perform link
tests. |
| Security Updates |
Fix |
Security updates to the NetBox system kernel, POP3 server
and DHCP client have been made in response to new security vulnerabilities
and threats. |
| Slow POP3 email retrieval when link down resolved |
Fix |
Logins to the NetBox POP3 server from the LAN were slow when
the Internet link was down. This has been resolved. |
| Email scanning hang fixed |
Fix |
A hang during scanning of emails with large numbers of attachments
has been fixed |
| Link info display corrected |
Fix |
The link statistics shown at Administration | link info
are now correct (was out by a power of 10). Also, the link statistics
are now scaled to more easily understood units. |
| Mailbox creation |
Fix |
A rarely encountered problem with creation of mailboxes when
changing a user's group membership has been fixed. |
| Minor bug fixes |
Fix |
Other minor bug fixes and security enhancements have been
made. |

| Verisign SiteFinder workaround |
New |
On the 15th of September Verisign, the company which controls
the root name servers for all .net and .com top level domains, activated
a system called SiteFinder. This system causes all DNS names which haven't
already been delegated to point to a Verisign advertising server and search
engine. Unfortunately, this system causes numerous problems with network
and DNS diagnostics, spam detection and also raises ethical and privacy
concerns. The NetBox now implements a workaround which prevents the SiteFinder
system from working and restores standard DNS resolution behaviour for
.net and .com domains. |
| Optimised SMTP mail handling |
Enhancement |
Internal handling of SMTP email has been restructured and
optimised. The NetBox is now capable of handling greater SMTP traffic
loads. |
| Cookie handling corrected |
Fix |
A minor problem with handling of cookies in the NetBox web
interface has been fixed. |

| Upper limit on maximum email size |
Enhancement |
The maximum email size that will be accepted by the NetBox
has been limited to 1GB. The user interface will now not allow you to
enter a larger value for this setting. |
| Improved email queue handling |
Enhancement |
Internal optimisations have been made to the handling of
SMTP email to improve performance under high load. |
| Improved frame relay support |
Enhancement |
More internal improvements have been made to the NetBoxes
handling of frame relay hardware. |
| SMTP "double-bounce" messages now turned off by
default |
Enhancement |
"Double-bounce" error messages to the administrator
are now turned off by default as they are generally not useful and generate
unnecessary traffic. This setting can be found under Administration
| Alerts in the NetBox web interface. |
| ISDN logs display |
Enhancement |
Improved output of ISDN related connection logs. |
| SMTP log display fixes |
Fix |
Some fixes to the output generated by the Administation
"View Logs" feature for SMTP logs have been made. |
| Webmail fixes |
Fix |
The NetBoxes handling of attachments in some messages when
viewed with the Webmail feature has been fixed. The handling of some specific
RFC2047 encodings in headers has also been fixed. |
Some items mentioned above are only available on your NetBox if you have purchased
