IPlanet Messaging Server 5.1

I downloaded IPlanet Messaging Server 5.1 and tried to uncompress it in Solaris 2.8 by gzip -d. However, i am getting the following error, gzip: ims-5[1].1-us.sparc-sun-solaris2.6.tar.gz: unexpected end of file..Please help out what to do.

Hi,

Your file wouldn't get downloaded fully since the file size is too large, try download with some download accelator software which supports resuming the broken downloads. Else look for a patch for iplanet Messaging Server 5.1 on solaris. Apply the patch and try install again.
