CVS ignores cvsignore when connecting via ssh

[Markus Michel]

Hello,

I defined some patterns in CVSROOT/cvsignore like this:

! *~ %%* sess_*

When I try to do a
cvs -d :ext:address@hidden:/var/cvsroot import -m test test vendor start

not only my defined files in cvsignore but also many others are ignored. 
All other cvsignore options left blank (.cvsignore in home folder; 
$CVSIGNORE; -I and .cvsignore in import directory and subfolders)!!!

When I try to import a module local on the server, CVSROOT/cvsignore 
works as expected.

Is it because I am using :ext: via ssh?

I have tested this on another server and it was the same behaviour. My 
cvs is version 1.11.17 on all machines.
