CSCF Printing Infrastructure Renewal

Purpose

Provide a modern reliable printing infrastructure to replace our legacy CUPS and LPD services.

Development plan

• set up a new CUPS print server, cups2.cs, using ubuntu-10.10 on a Linux Container
• initial OS configuration
• package selection and installation
• initial cups configuration and testing

• duplicate print queues from old cups.cs (services118.cs) to cups2.cs
• test and enhance the new queues
• move cups.cs CNAME from services118.cs to cups2.cs; test
• production testing
• decommission services118.cs

• improve monitoring of cups service on cups2.cs

• duplicate queues from old cups service on print.cs (services102.cs) to cups2.cs
• test and enhance the new queues
• reconfigure cups queues on print.cs to simply forward to cups.cs or lpd on print.cs
• production testing

• duplicate simple queues from legacy LPD service on print.cs to cups service on cups2.cs
• test and enhance the new queues
• reconfigure simple LPD queues on print.cs to simply forward to cups.cs
• production testing

• port lpquota service to pyquota

• duplicate remaining queues from legacy LPD service on print.cs to cups service on cups2.cs
• test and enhance the new queues
• reconfigure remaining LPD queues on print.cs to simply forward to cups.cs
• move print.cs CNAME from services102.cs to cups2.cs
• production testing
• decommission cups and lpd services on services102.cs

• set up a second new CUPS print server, cups1.cs, similar to cups2.cs
• duplicate cups configuration from cups2.cs to cups1.cs
• set up monitoring of cups1.cs
• test fail-over and load balancing between cups1.cs and cups2.cs
