hello - i just received a tar tape from someone using Irix and tar2local (sp?). i am trying to read it on a Sun4, but i am getting directory checksum errors. when i do an od -c on the device, it looks like when it wants the file name to be abcd (what it was to the Irix user), i see it as badc, etc, for the length of the tape. given that tar is supposed to be pretty platform-independent, why would this be occuring? any e-mail would be appreciated, or punt, er, post it. thanx - ray, ray@ganymede.apple.com

You will need to use 'dd' to swap the bytes. Try: dd if=/dev/tape of=<diskfile> conv=swab This will swap the order of the bytes, and give you as file which tar will read. Alternatively, if you want to bypass the disk tar file try dd if=/dev/tape conv=swab |tar xvf - James Petts #@# CAUTION - READ THIS .sig AT YOUR OWN RISK! @#@#@#@#@#@#@#@#@#@#@#@#@#@ @ # NOTE: VISIGOTH HAS NO # # Q.

Tell the folks on the IRIX machine to use /dev/tapens instead of /dev/tape
when creating the tapes for export. There are long historical
reasons for this (software) byte swapping; see 'man tps' on IRIX systems
if you are interested.
