Hello fellow FreeBSD users! I'm with a growing ISP who's about to do a mass OS conversion from NT to FreebSD. We've got most of the fine details down, except just a couple things I thought I might run by pros like yourselves: 1) NIS, NIS+, et al. I've been pulling my hair trying to set up NIS. I'm aware of the security issues involved with this, so I was wondering if anyone could tell me specifically why I should use NIS+, or not use NIS at all, if I'm going to be using it just for our local machines, one of which offers shell access (which wont be a master nor a slave). Also, does anyone know of a good place to read an FAQ on setting this up? I'm aware of the ORA book "NIS and NFS", but since I'm just expirimenting now I'd like to save that $30 for other books. I do believe I've got the concept of NIS down, basically it acts like the NT LanManager domain principle. There a Primary Domain Controller (or Master NIS server) that has all the accounts on it, the Backup Domain Controllers (or Slave NIS servers) replicate this information on a 10-minute interval, and all the domain members (or ypbind clients) connect to the master server for password authentication, username/shell/GECOS changes, etc. Can anyone tell me if I'm missing a crucial point? Anything you can add may help the man pages and the (lack of) documentation in non-NIS ORA books make more sense. 2) As I said, we're running an NT domain now and looking to convert to FreeBSD. Does anyone know of any way to convert the NT accounts over to FreeBSD? Money's no object, since the alternative is to hire temps for a week to do data entry. 3) Services. Right now we're running a mail server in NT (Post.Office, www.software.com), and looking to run that same software on BSDi. Has anyone ever run Post.Office in bsdi? Is it as bad as it is in NT? Would I be better off using qpopper/sendmail? What kind of resources would this alternative take for 500 or so concurrent pop3 connections? 100 concurrent smtp? (x86). Is there a good e-mail paging solution I could use in conjunction with either? Would FreeBSD be okay for these, or am I better off with BSDi? I would appreciate hearing any success/failure stories from people running Post.Office under BSDi, and anyone running qpopper/sendmail under freebsd with around the same load. 4) NFS. I'm looking to have an NFS machine which will house pretty much everything. All our customers web pages will be stored here, all the news, all the mail, etc. The actual service machines (mail server, web server, etc.) will just mount their respective directories on this server to deliver the requested data. Is this viable? The NFS server is going to be a custom-built, dual Ppro with 200mb ram (probably DIMM's), 8 4-gig drives using an Adaptec 2940UW, combining all drives into a single partition via ccp, will be running BSDi, all on a 100mbps LAN. Will this be a good enough solution for that much data? Will this give us room enough for expansion? If ANONE sees a problem with this, please let me know (I'm begging!), because if this baby can't cut it, it could mean my hide. :) 5) Lastly, I'm looking into building my own router for pop sites. I'm thinking of using a 486DX with 8 megs ram, internal T1 CSU card, and FreeBSD as its core components. This router will be handling probably nothing more then 48 33.6 lines over a Frame Relay connection to our main backbone. Will a computer be a reliable enough solution for routing IP? Thanks in advance to whoever takes the time to reply. Joe Read TRIAX Internet Services mfred@zen.triax.com, joer@triax.com
