Index: etc/rshd.c 4.2BSD [+FIX] Description: rshd does not establish the same umask as login. Files created via commands executed by rshd on behalf of a remote client have world write permission. Repeat-By: execute: rsh remotesystem umask and find that the result is consistently returned as 0. or: rsh remotesystem touch /tmp/foo and find that the mode of /tmp/foo is -rw-rw-rw- Fix: Add a umask call to rshd in the vicinity of line 270 as in the following code fragment: environ = envinit; strncat(homedir, pwd->pw_dir, sizeof(homedir)-6); strncat(shell, pwd->pw_shell, sizeof(shell)-7); strncat(username, pwd->pw_name, sizeof(username)-6); umask(022); /* set same default umask as in login */ Norm Seethoff John Fluke Mfg.

On our system (4.2 BSD) I worked around the problem by putting the umask statement in .cshrc instead of .login. You will need to do this anyway if you want anything other than the default.

This is because "/etc/cron" also suffers from this problem. -- UUCP: ...!seismo!mcvax!ukc!dcl-cs!stephen DARPA: stephen%lancs.comp@ucl-cs | Post: University of Lancaster, JANET: stephen@uk.ac.lancs.comp | Department of Computing, Phone: +44 524 65201 Ext. 4599 | Bailrigg, Lancaster, UK.
