Here are the results of my investigation: The incorrect permissions on /bin/_login were due to a mixup when updating the shadow-mk package's Makefile to correspond to the Makefile from the other shadow release. ** The 4755 perms do not appear present a security risk, however. ** The original /bin/login will deny any logged in user from using the -f (username) option if they lack sufficient privledge. Period. Indeed, the only reason -froot was a problem was that /bin/login determined that the "active user" calling /bin/login was indeed root and therefore had permission to use the -f switch. Any user, once logged in, cannot use the -f option unless that user is indeed root. For those persons interested in verifying this statement, log in as a regular user and type "/bin/login -f root" or "/bin/login -froot" and see what happens. You'll not become root. The problem was in rlogin and console logins, where /bin/login was being invoked by root itself, rather than being invoked as suid-root. Apparently, the old /bin/login uses getuid() instead of geteuid() to determine the real user id of the user executing the program. --Joseph R.M.

Date: 6 Sep 1994 18:13:59 -0500 I am having difficulty getting archie to work on my Linux box. I know archie used to work on Linux, because when we were at 0.99pl13 or so, it was working fairly consistently. Now since we've upgraded (now running 1.1.49), it seems that archie just times out. Has anyone else noticed this? I did some searching through the code, and it seems that some of the Linux libc does things a little differently than other Un*ces (select). This definitely affects at least some of the timeout code, which expects that select doesn't modify the timeout param. If anyone has fixed this, or if you have a version that works on Linux without timing out (I am using archie-1.4.1-FIXED), that would be great too. I know archie is still working, 'cuz it still works at school. Any help would be appreciated.

It would be a good job, if somebody who is able to, would port CAP to Linux. That would enable the Macintosh to mount Linux-Drives, since Linux simulates a AppleShare-Server. As far as I understand it, The Linux-Box will be able to mount Macintosh-Drives, when the Macintosh has turned on FileSharing. ===================================================================== Darko Krizic Langweidenstrasse 37 60488 Frankfurt 49 69 7893687 dekay@xtac.tg.sub.org MIME 4e71 "Powered by Motorola" ===================================================================== ------------------------------ From: dekay@xtac.tg.sub.org (Darko Krizic) Subject: Re: NFS Linux Mac Date: Tue, 6 Sep 1994 17:57:31 GMT > I use Client NFS for Macintosh from The Wollongong Group in California. > It works through the Chooser just like AppleShare. Right. That is the way, NFS/Share is integrated, too. You open the chooser, click on the NFS/Share-Icon and NFS/Share sends a broadcast to the network. Then you select a server, enter your username and your password and get a mount-poing dialog, where you cann add/edit/delete the mount points. ===================================================================== Darko Krizic Langweidenstrasse 37 60488 Frankfurt 49 69 7893687 dekay@xtac.tg.sub.org MIME 4e71 "Powered by Motorola" ===================================================================== ------------------------------ From: giles@fisonssurf.co.uk (Richard Giles) Crossposted-To: news.software.nntp Subject: Re: inn or cnews for linux?

That's right. Whenever you do a e2fsck, remount your fs read only. The Best way is to go down in Single user mode, and if the update daemon or bdflush is still active, get hime a kill -9 signal to terminate it. Then, you do your e2fsck an after it is done reboot your system. All these things should be in your /etc/bcheckrc and rc.S or rc.1 files. Here's how it works on my system: e.g, on my system, I type in "telinit 1" (My single user mode in my inittab), this rc.1 terminates me all processes, then call login for root to log in or restart at a new runlevel (Thats right, without Password, there's no Singleusermode on my system). When I`ve entered my root-password, the only programms running are a bash and the init process. Then, it is no Problem to do an e2fsck (Even while mounted) since no Processes are tryinig to write to the Harddisk's. : [other good info deleted] : Gary : ganderson @ clark.net -- ************************************************* * It s not a trick :-) !!
