UDP Checksumming
2007-12-25 8:01:00
data corruption problems with files transferred to his network
drive on a Sparc 2 (4.1.2). ftp Software says to turn on
UDP checksumming, but SunSolve reports an open bug (ID 1010947),
which says:
Bug Id: 1010947
Category: network
Subcategory: internet
Release summary: 3.5, 4.0, 3.4
Synopsis: Setting udpcksum does not cause NFS to checksum
Integrated in releases: 4.1
Summary:
There is a kernel variable call `udpcksum' that is
supposed to turn on UDP checksums. However, since
NFS uses its own path through the network code to send
packets (the module `kudp_fastsend.c'), it does not
take effect on NFS.
Is this bug corrected in 4.1.3? Solaris 2.x? Is there any
other solution? Thanks.
