Sybiz Vision; Keep Clear!

Just a few reasons I hate Sybiz Vision software.

  • Memory Leaks cause process to exceed 2gb when then causes crash on 32-bit systems (memory addressing limitation).
  • Passwords limited to 8 characters.
  • Passwords stored in Clear Text
  • No Data Dictionary for their own Database.
  • Delivery Instructions for an Invoice are stored on the corresponding Order. Therefore if an order is invoiced more than once (eg, part deliveries) then the Delivery Instructions on ALL the invoices and the original order are changed to whatever the last invoice had for it's Delivery Instructions.
  • Usernames and Passwords are pointless when each users needs file system access to the Foxpro DBF database files. They can just be copied to the local drive and easily read or converted to other formats (eg, using the "eyeball" tool, or pgdbf).
  • Their "Support Partners" are useless. We offered a development contract to 2 completely separate partners who expressed interest and assured us they could do it but couldn't deliver ANYTHING after 6 months.
  • If you discount an item you've sold, there is no record of this discount kept in the General Ledger. Your sales just decrease by the discount amount rather than posting a reduction to sales and increase to "Sales Discounts" or similar.

So here's a big FUCK YOU WITH A SMILE to Sybiz Software.

Sybiz Vision vs. Unix Philosophy

Let's see how Sybiz "Vision" stacks up... I know "Vision" isn't a *nix application, but the rules are sane for for software of any platform, regardless of their overall title.

Native IPv6 with Internode and CentOS

This is a WIP. Notes so far.

At the moment, this results in an error from DHCPv6 Client when trying to assign an addrss to ppp200:

Feb 10 23:28:50 tank dhcp6c[1063]: transmit failed: Network is unreachable

Manually adding an address makes it work:

Feb 10 23:28:47 tank dhcp6c[1382]: request prefix is 2001:44b8:7206:d180::/60
# ip -6 a a 2001:44b8:7206:d180::1/48 dev ppp200
# ping6 2001:44b8:1::6
PING 2001:44b8:1::6(2001:44b8:1::6) 56 data bytes

Custom Actions with fail2ban

Most people are familiar with the fail2ban package available for protecting against brute-force password attacks against your servers.

Fail2ban scans log files like /var/log/pwdfail or /var/log/apache/error_log and bans IP that makes too many password failures. It updates firewall rules to reject the IP address.

What you might not have experimented with is it's ability to execute custom actions instead (or as well as) blocking the source IP in iptables.

Sheriff Joe is at it again!

Maricopa County was spending approx. $18 million dollars a year on stray animals, like cats and dogs. Sheriff Joe offered to take the department over, and the County Supervisors said okay.

Australian Governments could (should) learn a lot from this guy.
