It has happened twice now that users have been unable to login to my DS5000 running Ultrix 4.1. When I log in as root and try to "su" to a user, I get the message "No shell." Checking around, I find that the root directory has permissions "rw-rw-rw-"! I change to "rwxr-xr-x" and everything returns to normal. Any idea how root is becoming mis-permissioned? -- Joshua Yeidel

Ultrix used to have a problem with changing the protection of the parent directory of mount point of the file system being restored. I would hope this was fixed by 4.1, but I wouldn't bet any great amount of money on it. I see this problem most frequently when doing a partial restore to /tmp to extract some files, and then find the protection on /tmp has been changed from 666 to 755, which causes some strange diseases... -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing: domain: grr@cbmvax.commodore.com Commodore, Engineering Department phone: 215-431-9349 (only by moonlite)
