Setting up SSH on U14.04 Server -- I Messed Up File Ownerships

[mhumm2]

Yep. That's what I get for following the advice from other forums. So what are the default/usual/normal/correct directory and file ownerships?

[root directory]

Here's the real problem I think:
[As user, not root, from the home directory]
mark@server1:~/.ssh$ ll
ls: cannot open directory .: Permission denied
mark@server1:~/.ssh$ cd ..
mark@server1:~$ ll
total 36
drwxr-xr-x 4 mark mark 4096 Aug 6 19:26 ./
drwxr-xr-x 4 root root 4096 Aug 9 00:24 ../
-rw------- 1 mark mark 5888 Aug 8 14:11 .bash_history
-rw-r--r-- 1 mark mark 220 Aug 3 10:00 .bash_logout
-rw-r--r-- 1 mark mark 3637 Aug 3 10:00 .bashrc
drwx------ 2 mark mark 4096 Aug 3 10:03 .cache/
-rw-r--r-- 1 mark mark 675 Aug 3 10:00 .profile
drwx------ 2 700 mark 4096 Aug 6 19:26 .ssh/
mark@server1:~$
[/output]

Somehow I have the owner of the .ssh directory as 700! As mark, I can not access this folder. I want to got back to the correct ownership of these directories. Next time I'll be more careful to use chmod instead of chown.

sudo chown mark.mark .ssh/ -R

actually, for good measure
cd /home
sudo chown mark.mark mark/ -R

[mhumm2]

doesn't the -R option come before the names? I'm trying...

[mhumm2]

yep,

-$ sudo chown -R mark.mark .ssh/
It worked. Thanks.

[Snowhog]

Yes. While in your user /home directory:

chown -R mark:mark .ssh

i dont think it matters, in this case

CHOWN(1) User Commands CHOWN(1)

NAME
chown - change file owner and group

SYNOPSIS
chown [OPTION]... [OWNER][:[GROUP]] FILE...
chown [OPTION]... --reference=RFILE FILE...

[millusions]

there's no need for man,

since : sudo chown mark.mark mark/ -R

works just fine,

so what if man says different?

just try it

added: i have a suspicion that -R switch 'recursively' can be added at to any command that will accept it.

[mhumm2]

It's difficult to argue with success. Thanks. I have my directories corrected. Now on to ssh-agent.

Please don't discourage people from reading documentation.

Some commands accept arguments that themselves take options. A made-up example might be:
foocmd --opt1 --opt2 argument1 --opt11 argument2 --opt21

If --opt1 were specified at the end, it would affect only argument2 rather than the entire command. The man page expresses the proper convention, because when learning the command line, it's best to learn these conventions early. Having to undo learning is difficult.

added: i have a suspicion that -R switch 'recursively' can be added at to any command that will accept it.

It can be added to any command whose documentation mentions that it's a supported option. The best way to check? Read the man page for the command.

[millusions]

fair enough,
it just seems logical, to me anyway, to put -R at the end
