useradd creating home directory 755 instead of 700

[pradeep10]

HI All, Good Evening!!!

This doubt might be silly, but this is creating lot of security exposure.

When i create a user account using user add command, the home directory is getting created with 755 permission instead of 700 permission.

I've tried all means but no luck. i need the home directory to be created with 700 permission when i shoot useradd command. Can anyone help me out to resolve this issue.

Many Thanks in advance!!!

Regards,

Pradeep.

I have not been able to find a way to do that yet.

It would make sense for your umask to control that, but I set umask to 077 and a homedir was still created with 755 permissions.

I will continue to search.

Is there anything in /etc/default/useradd that controls it?

Otherwise you can just use chmod go-rx after the useradd.

[Patrick Wallek]

No, nothing in /etc/default/useradd regarding permissions.

Thanks everyone who gave a try for my query....I tried using /etc/default/useradd , but no luck ..one thing I need to mention here, if I have unasked as 077, and if I create the account using Sam, then home directory gets created with 700 permission....

I thought I checked recently but is there a useradd.sam like usermod.sam?

[Patrick Wallek]

Yes, there is a /usr/sam/lbin/useradd.sam, but it is just a link to /usr/sbin/useradd.  I looked at it but did not see anything that allows you to specify the homedirectory permissions.

>it is just a link to /usr/sbin/useradd.

The program can just look at argv[0] and do something different.  Like usermod.sam.

But did you try it? ;-)  Of course kind of hard to find options if not present in the help.
