- In the oldies but goodies department:
-
- There are some problems in the NAMRES program, but for the most
- part they are fixed in 6.6.5-A. There are also a few things you can do
- to make NAMRES run more reliabily:
-
- First, make sure MAXBUF is greater than 2400. Fortunately, this
- parameter can be adjusted while the system is running.
-
- Second, include the Internet root servers in NAMRES.CONFIG:
-
- DOMAIN_SERVER:.:kava.nisc.sri.gov.:192.33.33.24:53
- DOMAIN_SERVER:.:AOS.BRL.MIL.:192.5.25.82:53
- DOMAIN_SERVER:.:C.NYSER.NET.:192.33.4.12:53
- DOMAIN_SERVER:.:TERP.UMD.EDU.:128.8.10.90:53
- DOMAIN_SERVER:.:NS.NASA.GOV.:192.52.195.10:53
- DOMAIN_SERVER:.:NIC.NORDU.EDU.:192.36.148.17:53
- DOMAIN_SERVER:.:ns.nic.ddn.mil.:192.112.36.4:53
-
- Third, add these lines to your NAMRES.CONFIG:
-
- Variable:RECURSE:1
- Variable:TIMEOUT:5
- Variable:REFMAX:10
-
- Fourth, if NAMRES goes out to lunch, you can kill it via the following
- command:
-
- IPNCP>NAMRES EXIT
-
- and restart it via a little command file like this:
-
- $ RUN SYS$SYSTEM:NAMRES.EXE /NOACCOUNTNG -
- /NOAUTHORIZE /QUEUE_LIMIT=100 /DUMP -
- /BUFFER_LIMIT=65535 /IO_BUFFERED=65535 /PRIORITY=6 -
- /IO_DIRECT=32767 /AST_LIMIT=200 /DETACHED -
- /PRIVILEGES=(CMKRNL,SYSPRV) /UIC=[1,4] -
- /MAXIMUM_WORKING_SET=3000 -
- /PAGE_FILE=80000 -
- /process_name=NAMRES
- $ exit
-
