When ssh into my home router, I use the admin credentials provided by my isp. How do I list all users along with their details (group/privilege) and as the superuser how do I modify their (and my) username?

Check your router manual, it depends on router model.jherran– jherran2015-02-22 07:31:53 +00:00Commented Feb 22, 2015 at 7:31

Really? I thought its more on the os side ie: openwrt vs tomato. My router is dlink dir-615 running stock firmware based on busybox.harayz– harayz2015-02-22 12:24:41 +00:00Commented Feb 22, 2015 at 12:24

Username is nothing more than two things:
- a record in
/etc/passwdfile - a record in
/etc/shadowfile (if your system uses it)
When talking about routers, most of them do not use /etc/shadow, so to rename a user you have to change it in the file /etc/passwd and here you go. Use sed for it.
Changing root username doesn't look like a good idea - there could be software with hardcoded root username, for sure.
