umask and default file permission

thanks dpiniella.

i add umask 0000 to .shrc and when i re logged back in and my umask is 0000.

however, the file permission is rw-rw-rw, but i need it to be rwxr-xr-x.

what else should i do.

thanks

if the file is already created, changing the umask won't do anything -- umask only comes into play when it's a newly created file.

i know that part.  however, currently after i change the umask, and create a new file, the default permission is 0666.
it used to be 0644.  thus, i believe the umask in shell rc work.
however, i need the file permission to be 0755 instead of 0666.

thanks dpiniella.

chmod will not work because all the new files don't have any execute permission w/ them.

thanks dpiniella for helping me out here.

you don't need to have execute rights on a file to chmod it -- you need to either own it or be part of the group that owns it:

[root@here ~]# ls -la hello
-rw-r--r--  1 root root 0 Mar 13 15:43 hello
[root@here ~]# chmod 755 hello
[root@here ~]# ls -la hello
-rwxr-xr-x  1 root root 0 Mar 13 15:43 hello
[root@here ~]#

thanks dpiniella.

it is upload through the internet and the perl script does not own nor in a group that owns it.  that's why i need to have all the file default w/ execute permission.

in freebsd, is there a way to give all files the default execute permission??

thanks

run a script that changes permissions on the files every certain period of time is the first thing that comes to mind. ideally you'd check the permissions needed to be changed before you chmod them.

actually i am looking for something similiar to umask that allow every new file that the internet user create will have a default execute permission.

running a script every certain period of time will not work for me.

thanks

...set that user's umask to 066. This will give files they create rwx--x--x permissions. Be sure to use /usr/bin/umask, not the shell's built-in function.

i tried the /usr/bin/umask and still didn't work.
i just need the default permission bit turn on when an internet user create a new file w/o using chmod.

thank dpiniella.

ooops.  i forget put execute in previous comment.

i tried the /usr/bin/umask and still didn't work.
i just need the default "execute" permission bit turn on when an internet user create a new file w/o using chmod.

thank dpiniella.

> actually i am looking for something similiar to umask that allow every new file that the internet user create will have a default execute permission.
this will not happen
umask masks out some bits for files
if creator program does not want +x bit, then umask is of no help

compilers do produce +x files, editors do not.

thanks gheist.  can you explain more details.

currently i am using a perl code to create a new file.

but in perl, there is no way i can give default execute permission.

how can i configure my compilers to give default execute permission.

thanks

Perl was not mentioned.
Perl behaves like editor. It can set permissions http://www.perl.com/doc/manual/html/pod/perlfunc/chmod.html

Compilers do create executables and mark them so.

the chmod does not work in this case.

the internet user upload the file.  once the file is upload, the file's owner become "UserA" and the perl script can't chmod because it does not own the file and does not have execute permission.

thus, i like to have the default execute permission turn on.  in this case, the perl script can chmod it.

thanks

Explore SITE command set of your FTP server:
rhelp site
site help

They usually offer anti-idle and chmod.

thanks gheist.

i got the site command to work, but i didn't see anything that involves w/ anti-idle and chmod

but i did find the following information, not sure if it is useful.

httpd was not involved in question, so keep it off the discussion.

when i ssh into my server and su to super user.
i type "help site"
help: Command not found.

i type "site help"
site: Unknown command 'h'

but when i type "site"

I need you to telnet to plain ftp server port instead of accessing its admin tools over SSH

That will look like this (colon prepended to what you have to type):
( example taken from actual FreeBSD system, usernames/hostnames replaced)


> telnet ftp.server.dom 21
220 ftp.server.dom FTP server (Version 6.00LS) ready.

i tried to telnet in but it does not work.

here is the error message

i tried port 21
500 syntax error, command unrecognized.

i tried port 23
could not open connection to the host, on port 23: connect failed.

And what command you typed ???? Did you wait for service banner?

i typed
telent 111.222.333.444 21

then i see
220 aaa.bbb.com NcFTPd Server (licensed copy) ready.

then i type
:USER userA

then i see
500 Syntax error, command unrecognized.

if i don't type anything, then within 20 seconds,
421 disconnecting you since you didn't login successfully within 20 seconds

i figured it out.

i type "USER userA" instead of ":USER userA" and it works.

anyway, when i type "site help" or "help site"
i get

bufsize
chmod
date
df
quotz
rbufsiz
rbufsz
retrbufsize
sbufsiz
sbufsz
storbufsize
symlink
umask
utime

when i type "syst"
i get

Unix type: L8

So you have chmod command server over FTP

type
 SITE CHMOD 0777 filename.xxx
inside raw ftp session.
If your default FTP client does not support raw commands, use ncftp or lftp that do even instrument SITE CHMOD using chmod ftp client command. In Windows 3.11 ftp client raw commands can be entered using "lit" command

SYST is used for server type autodetection by most of smarter FTP Client software, yours look good enough - just UNIX, no MVS, windows or whatever.

i can NOT use chmod.

the problem current is that when an internet user upload a file by using web browser such as IE or firefox, the perl script will receive that file.  however, when the file is created by perl script, it is default to userA and w/ permission of 0644.  since the file is created w/ 0644 and the owner of file is not internet user or perl script, the chmod will not work because it does not have any execute permission on it.  so my question is how to turn on the default execute permission.

currently i played w/ umask, w/ umask 022, i get 0644 and w/ umask 000, i get 0666.  

thus, i am looking for a way to turn on the default execute permission.

thanks

You have to run perl script as web user.

all files are default to userA.

i am not sure what is the user and group for a web user.

i think it is something like www:httpd but again, since i am a newbie at freebsd, i don't know what to do.

thanks

by the way,

the perl script is owned by userA:userA

and all files upload by web user is owned by userA:userA also.

thanks

Then you can change permissions of perl script to your liking using SITE CHMOD of FTP server.

But if you run this script and create files as another user, they are immutable to ftp chmod.

i didn't create it this way.  this comes as a default.

i believe the server admin did this part, i am just a programmer.

currently i think the quickest way to fix this is to have all files created w/ default execute permission.

in order to have chmod work on any files regardless of ownership is to have all files comes w/ default execute permission.

thus instead of created a file w/ default permission of 0644, i need it to have 0755.

thanks

Server admin did nothing. Programs other than compilers do not set +x on files, because it is meaningless to execute random data.

use site chmod of your ftp client to adjust permissions as needed.

i can't use site chmod of my ftp client to do this becaus everything should be automated.

imagine an internet user upload 2 ~ 3 files a day, i don't want to ftp in and chmod everyday.

thus, the only solution of doing this is to have all files created default w/ execute permission and perl script will chmod the file everytime an user upload a file.

not that I don't appreciate the points, but I feel gheist deserves _something_ for all the troubleshooting he's done.

true.  i believe that he did deserve points.  however, my problem is still not solved.
