I got 21 replies to my problem. This list is great!!
The solution was quite simple but I don't think I would have
come up with it in such a short time and with so much stress on my back.=20
Thank you all.
Most of the replies said that I should boot form the cdrom,=20
mount the root partition and then fix the passwd file.
Although something is mentioned in the Solaris 2 FAQ about=20
changing the shell for root it should be more explicit in saying
that you should really not change root's shell at all in the=20
passwd file, here are some of the reasons why (Thanks to Christian
Masopust)
1) there is no /sbin/csh!
2) don't use shells of /bin/*sh, because the are dynamically linked and
need some libs of /usr/lib/... The problem is that in single user mode
they are not available.
3) if it's really neccessary to use any other shell than /sbin/sh you have
to statically link your shell and put it into /sbin/
Susan M. Menig also mentioned that after I fixed my problem if I
wanted to run csh anyway I should include in root's .profile the following
line exec /bin/csh I think I'll probably do that.
Finally, here's the step by step solution to my problem which is almost
identical to the one mentioned by Srinvvasa Yalavarthy (I used /mnt as
mount point, but you should really use /a as the mount point.. It's safer)
- boot from cdrom
- After you get into OpenWindows open a cmdtool
- execute the following:
=09cd /
=09mount /dev/dsk/c03td0s0 /mnt
=09cd /mnt/etc
=09vi passwd
=09modify root;s shell to /sbin/sh
=09reboot
Thanks to the following and all those whose replies are probably in their
way:
