Re: [SLUG] Minimum username length?
Anyone know if there is a default minimum username length for some (or all) current Linux distros? One character. My employer allows people to choose their username and a lot of people use initials (of 2-5 letters). If you are setting up a new policy, I'd suggest something not based on name at all. Mainly because one of the few constitutional rights we have is the ability to change our name after marriage, and sysadmins that refuse to change the associated username find themselves on the losing side. But of course, technically changing the username is a real pain, so better not to place yourself there at all. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] Minimum username length?
I thought useradd(8) would enlighten me, I thought I remembered this being defined in either /etc/login.defs or /etc/security/limits.conf, but it's in neither. I honestly don't think there's a minimum username length limit. Feel free to be d@ ;) 2008/5/16 DaZZa [EMAIL PROTECTED]: Folks. Anyone know if there is a default minimum username length for some (or all) current Linux distros? I have a vague recall from somewhere it's 4 characters minimum - but can't find any documentation to back this up.

Re: [SLUG] Minimum username length?
3 characters works in ubuntu and redhat out of the box. Redhat has a minimnun password length of 5 and not all letters. Ken DaZZa wrote: Folks.

My copy of O'Reilly's Practical UNIX and Internet Security (3rd edition) says that standard passwords are 1-8 characters, although modern systems will allow longer. Most of my work involves debian, and RHEL of varying ages. They all have system users with short names (bin, sys, lp and the like). The only time I've seen a single-character username was one added by a dodgy rootkit. -- Pete -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
