Linux Support Service Recommendations


The tables that follow list APARs and PTFs that are relevant to providing or utilizing Linux guest support within a TCP/IP network environment. Each table lists APARs that are relevant to use of the following protocol services:

Because most of these APARs are (or will be) included on an RSU for a given level of TCP/IP for VM, it is strongly recommended that current RSU maintenance be applied to Linux-supportive systems.

Note that additional APAR maintenance (not listed here) may be required to address specific problems. Please contact the TCP/IP for z/VM support group for additional information and assistance if you suspect a problem that does not appear to be addressed by the maintenance listed here.

Notes:

  • This information was last updated on: 05 April 2004

  • Complete APAR descriptions can be obtained by clicking on the various APAR numbers listed in the tables that follow.

  • A PTF "number" of N/A indicates that a PTF is not yet available.

  • Pre-requisite, Co-requisite and Supersede PTFs are not listed in the tables that follow. When an order is placed for any listed PTF, you should check for and obtain any applicable requisite service.
