Re: bootable USB flash drive questions
Hi Urs here are a couple of notes on the subject I havent done it in a few years but my past experience may be useful. 1) on the subject of the mother board not supporting booting off the USB drive it doesn't matter because Grub supports it so if you install grub as the boot loader on your hard drive it can handle it for you. 2) its not the USB bandwidth you need to worry about with speed. Most USB flash drives are far slower than the USB bus some of them measure in the hundreds of Kilobytes per second so don't expect speed unless you buy a very high end Flash drive. that said Ram helps a lot and there are some other hybrid options you can look at SuSE's live (DV|C)D's traditionally allowed booting off of the CD and merging it with persistent data on disk images on an Fat32 or NTFS drive it can give you more speed but at the cost of shortening the life span of your DVD drive because of the constant use. so there are alternative options you could evaluate. 3) more ram will help the more you can keep in ram the better your performance will be. 4) do not put a swap partition on your flash drive! it will eat the total life time writes very quickly however if you absolutly need too then resuce the swappienes 5) use tempfs as much as possible. use it for /tmp and if you can for /var/run and /var/log it will eat some ram but it will significantly increase the life span of the flash drive.

I guess there is no speedup using a USB 2 flash drive. Hi Urs, Just playing around with it in KVM, I'd say it boot about 4 times faster than a CD on one of my customer's computers -T -- ~~ Computers are like air conditioners.

Re: Wanted LDAP server configuration documents
That's an old good but out of date document.The big question is do you want to do LDAP 2 or 3.The big difference is Kerberos in 3 or not and are you planning to use no encryption or SSL as in version 2 or TLS as in version 3 which is similar but has some additional DNS requirements.Also that document refers to openldap which I used for many years but I would advise you now to look at 389 server which was one of the original LDAP servers written by Netscape Security Solutions and is now owned by Red Hat also under RHDS and the basis of Oracles Directory Server due to a commercial fork agreement negotiated between SUN and AOL after AOL bought Netscape. Its not perfect but its GPL and in many ways better than OpenLDAP as a server platform and truly the good parts existed before Netscape died to the point where the first time I saw the java GUI a couple of years ago I fell on the floor litteraly bec)s of the nasty flashbacks of supporting the SCO version and the NT 4 domain controller sync plugin in the late 90s-- Sent from my HP Pre3On Mar 23, 2014 19:45, Steven Miano mian...@gmail.com wrote: This is a very good starting point:http://www.tldp.org/HOWTO/LDAP-HOWTO/installing.html On Sun, Mar 23, 2014 at 7:41 PM, Pritam Khedekar pritamkhedek...@gmail.com wrote: Dear All, Please send me some LDAP config documents if available.
