The point is some 5.25" drives support variable gap sizes, while others only allow fixed gap sizes. The easy way to tell if it works is to try it. On my machine it doesn't work, on yours it does.

Two things to make sure of: you must be booting with your root partition readonly, and you must be using at least version 0.3 of e2fsck. If root is being mounted readonly, you will get a message VFS: mounting root (ext2 filesystem) readonly. at startup. If it misses the 'readonly' bit, then root is being mounted writeable, and you should add a 'read-only' flag to the /etc/lilo/config file and reinstall lilo (/etc/lilo/install). If you need a newer e2fsck, you can find the latest e2fsprogs on ftp.ibp.fr or tsx-11.mit.edu in /pub/linux/BETA/ext2fs.

Date: Fri, 1 Oct 1993 22:53:44 GMT Hi, I compiled the pcnfsd sources by sun for linux, but when logging in from a dos-box i get authentication errors. I suppos it has to do with the SLS shadow-password suite. Does anyone have a working copy of pcnfsd ?

Date: Fri, 1 Oct 1993 22:58:17 GMT Hi everybody, following problem: I have an internal net, class C, ip 200.200.200.0 (nothing to do with a real existing net). When I use 200.200.200.1 to connect via slip to the real existing 192.109.159.1 I have to be 192.109.159.132. How can I do that ? It would be fantastic if I can furthermore connect from 200.200.200.10 to any existing host in the internet. Is that possible ? -- Origin: It's not a bug, it's a feature ! ------------------------------ Crossposted-To: comp.unix.admin From: gperez@tortel.dcc.uchile.cl (Gonzalo Perez Castro) Subject: Re: [Summary] /etc/shutdown by non-root Date: Sat, 02 Oct 1993 00:31:19 GMT Can anybody send me this summary please.
