RedHat List, I was working on a script the other day and ran into an anomaly with the file permission's on files. I have checked this on several ES servers and all produce the same results. Say a file has the following perms: 644 and it is owner and group are root:root. as long as a user has write permission's to the directory it is in they can write to it. not only that the UID:GID change to that user. I am running ext3 file systems with kernel 2.4.21-20.ELsmp. So my question is 1) why is this allowed? 2) can I change this? # pwd /home/test_dir # rm test.fil # pwd /home/test_dir # ls -ld . drwxr-xr-x 2 user7 root 4096 Apr 14 16:56 . # id uid=0(root) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel) # echo "test from root" > test.fil # ls -l test.fil -rw-r--r-- 1 root root 15 Apr 14 16:57 test.fil # su - user7 $vi test.fil $ ls -l test.fil -rw-r--r-- 1 user7 user7 31 Apr 14 16:57 test.fil $ cat test.fil test from root test from uset7 However it doesn't let you echo "test from user7" > ./test.fil. it responds correctly...... Any thoughts on this would be great. -David Knight -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
