RE: [CentOS] Odd Question... MAX Ram Disk Size
by Scott Heisler 31 Mar '05

31 Mar '05

Thanks everyone for the great INFO... This was EXACTLY what I needed and had a very hard time finding out. The mount -t tmpfs -o size=1g none /ramdisk worked perfectly. I needed temporary ram space to use as disk space. Thanks! Just to explain further, the "images" are not ISO's... These are hard drive images, like GHOST files (only using a Linux free application). But to further explain, even if I mounted an ISO, there would still be disk IO.. I'm trying to eliminate the disk I/O from the equation so I can be downloading 20 or 25 machines at the same time. Since the server us a dual 2.0gig Xeon and I have gig all the way from the server to the desktop.. This should scream! Thanks again.

OK. time to make some contribution (centos4/ppc)
by Pasi Pirhonen 31 Mar '05

31 Mar '05

Hi, Even now someone is actually installing (i see that from the ftp-server logs) the centos-4/ppc beta-version from announced place. You people have to stand up and _TELL_ me what kind of hardware _IS_ working, so we would know more than already know - 43p works. I can't believe that all those, who installs, does have 43p too? Please? Something, so if it's actually working on something else than already known 43p, we'd really like to hear about it. If it's not working, we'd still ike to hear about it as one can't fix anything not known to be broken. Someone something, so eventually there would be release? -- Pasi Pirhonen - upi(a)iki.fi - http://iki.fi/upi/

RE: [Centos] Restart centos from Commandline

you need to learn business i think ) to create multi dollar business, you need ideas, a team of people, a vision and a risk.

To create multi billion dollar business you need money. Because only money can create more money. Everyting else is small details that will be taken care of by people who will never profit from the business itself. Just look at Microsoft, at the beggining you had one guy who had more money than he could ever possibly need, and he become even richer because he was rich to begin with. On the other side you had bunch of developers whose wealth is constantly at about the same level (not that I feel sorry for them looking at the final product).

RE: DHCPd Config or HOW-TO on DNS + DHCP + SQUID +Firewall + Router

I thought I'd share this with you guys:- Been working/testing on the DEV release of SME7a3 based on CenTOS (on VMWARE), see contribs.org. Pretty neat I must say, most daemons (DNS, DCHP, SMB-PDC, LDAP, IMAP, POP, Web Admin) are preconfigured. I've got phpGroupware, WebERP, KnowledgeTree + other running on the same box (VMWARE). I've always had a challenge with manually configuring listeners etc and this has saved me hours/days on the Development I'm working on.'
