NIS or not?
by Sorin Srbu 29 Jan '14

29 Jan '14

Hi all, We're getting to a point in our linux environment where it's starting to be cumbersome to keep shadow and passwd-files up-to-date for the users to login on each computer. Scripts can only get us so far. 8-/ I've looked a bit into central login systems for linux, and NIS and LDAP seem to be prevalent. NIS being the simpler-to-setup solution for small to medium networks as I understand it, while LDAP is the more modern and scalable solution. See eg http://www.yolinux.com/TUTORIALS/NIS.html or http://sysadmin-notepad.blogspot.se/2013/06/nis-server-setup-on-rhelcentos.…. NIS-wise, what is a "small to medium network"? We have currently about 20-30'ish linux clients and servers, and the environment is not likely to increase much beyond this point. Is a 30ish-computer setup, a small network? The only thing I'm trying to accomplish is a system which will allow me to keep user accounts and passwords in one place, with one place only to administrate. NIS seems to be able to do that. Comments and insights are much appreciated! -- BW, Sorin ----------------------------------------------------------- # Sorin Srbu, Sysadmin # Uppsala University # Dept of Medicinal Chemistry # Div of Org Pharm Chem # Box 574 # SE-75123 Uppsala # Sweden# # Phone: +46 (0)18-4714482 # Visit: BMC, Husargatan 3, D5:512b # Web: http://www.orgfarm.uu.se ----------------------------------------------------------- # () ASCII ribbon campaign - Against html E-mail # /\ # # This message was not sent from an iProduct! # # MotD follows: # Artificial Intelligence: the art of making computers that behave like the ones in movies. -Bill Bulko

Installing on USB Flash Drive
by Matt 29 Jan '14

29 Jan '14

Is it possible to install CentOS on a USB Flash Drive. Have boot sector, / and /boot on USB drive then put /home, etc on a software raid array of the physical drives. Thought there used to be motherboards with SDHC slots that you could use to boot off.

It took a VERY long time to get setup and > working, but it is now. The main reason is the age of the equipment and software. The current domain controller host is from c.2004 and the software is Microsoft Advanced Server 2000. The Windows 7 workstations work with this AD but there are a few quirks. As the equipment is well past its best before date we need to replace it. We have virtualised just about everything else saving only the desktop workstations and this is another candidate for virtualisation. As a company we are moving everything we can to FOSS and away from proprietary interests. Therefore the combination of moving from MS-AS2000 and a dedicated host to Samba4 running on a virtualised guest seems an attractive option, provided that it works. Thus my question. The research I have done seems quite promising. It is now possible to promote a Samba4 server to an AD domain controller and to transfer all the Flexible Single Master Operations (FSMO) roles to it. It should then be possible to promote a second virtualised Samba4 server running on a different virtualised guest running on a second hardware host as a domain controller. Once done then the original AD host can be demoted and shutdown. Providing Samba4 works as described of course, which is why I am asking if anyone else has done it. There remains an issue with the SysVol replication, there is not any, but this can be worked around via rsync and cron. However, this means that all directory maintenance has to be performed on just one of the DCs, which effectively returns us to the days of Primary/Secondary DCs. Since in our case we are down to just one AD as it is this is not a hardship. Do you have a writeup of what you had to do to get CentOS to authenticate against AD? -- *** E-Mail is NOT a SECURE channel *** James B.

I figured if the asker was really that anxious for 'latest and greatest' to test, let them get a taste of it. I also inferred 'newer software to test' to mean it would not be going on a production machine. (I'm not sure why Thunderbird sent the last one to your email instead of the list. Sorry.)
