Actually, although such dissemination of information can be blocked by a correctly designed firewall, I suspect the Free IPv6 DSL Modem and Router, Sponsored by your-favorite-commercial-site that comes with your ISP contract, would err on the side of promiscuity. Why yes, yes you are giving up some of your privacy. And unless you have the time and are willing and able to learn how to configure firewalls for each device and application you use, or have the money to pay someone else you trust to do it for you, there is very little to protect you from the rest of the world. That's at least overstated, and at worst complete FUD. Generic modems and routers will be configured as they are now - with stateful firewalls blocking all incoming traffic, except for streams initiated internally. Outgoing connections that would have worked before via NAT continue to work, but without NAT. Stateful firewalls are still stateful firewalls. Where are you giving up some of your privacy? The number of hosts on your internal network? So allocate 256 ips (or 65k, if you like) to every host and use a random ip from that set for every distinct service or outgoing connection. There _is_ more information leakage with ipv6, in the sense that you are using a real ip from an internal machine on the connection. But the point is that the security benefit of that is largely illusory, security by obscurity. Cheers, Gavin ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Deduplicated archives via hardlinks [Was: XFS or EXT3 ?]

For 'normal' sized backups they work pretty well, but for some value of 'large' backups the number of inodes and the tree traversal time starts to cause real performance problems. I'd be interested to know how large people's backups are where they're still seeing decent performance using approaches like this? I believe we started seeing problems once we hit a few TB (on ext3)?

Though I agree Maildir is generally nicer for differential backups. Agnello, how long is a lot of time? A backup is always going to have to walk the entire tree and checksum (or at least stat) every file, so there's a minimum cost you're always going to have.

[CentOS] ipmi regression in 4.5?
I've been monitoring CPU temperature on a few Dell SC1435s running CentOS4 via OpenIPMI and 'ipmitool sdr'. It's been working very nicely, but the upgrade to 4.5 not so long ago seems to have broken something: # ipmitool sdr type Temperature Temp | 01h | ns | 3.1 | Disabled Planar Temp | 04h | ok | 7.1 | 30 degrees C Temp Interface | 53h | ns | 7.1 | Disabled The disabled sensors above used to work fine, and there have been no config changes or bios upgrades or anything. All machines affected post 4.5. Any suggestions? Cheers, Gavin ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] PXE problems with syslinux 3.51
Anyone else seeing problems doing pxe boots off the latest dag/rpmforge syslinux packages? Versions 3.35 works, doing the tftp request like this: Jun 18 06:01:19 boothost in.tftpd[25947]: RRQ from 172.16.0.26 filename /centos5-i386/pxelinux.0 Jun 18 06:01:19 boothost in.tftpd[25947]: tftp: client does not accept options Jun 18 06:01:19 boothost in.tftpd[25948]: RRQ from 172.16.0.26 filename /centos5-i386/pxelinux.0 Jun 18 06:01:19 boothost in.tftpd[25950]: RRQ from 172.16.0.26 filename /centos5-i386/pxelinux.cfg/03-03-13-83-83-d3-a3 Jun 18 06:01:19 boothost in.tftpd[25951]: RRQ from 172.16.0.26 filename /centos5-i386/pxelinux.cfg/AC10001A Jun 18 06:01:19 boothost in.tftpd[25957]: RRQ from 172.16.0.26 filename /centos5-i386/vmlinuz Jun 18 06:01:19 boothost in.tftpd[25958]: RRQ from 172.16.0.26 filename /centos5-i386/initrd.img Versions 3.50 and 3.51 request the filenames without the leading /centos5-i386, and fail: Jun 18 06:05:13 boothost in.tftpd[25947]: RRQ from 172.16.0.26 filename /centos5-i386/pxelinux.0 Jun 18 06:05:13 boothost in.tftpd[25947]: tftp: client does not accept options Jun 18 06:05:13 boothost in.tftpd[25948]: RRQ from 172.16.0.26 filename /centos5-i386/pxelinux.0 Jun 18 06:05:13 boothost in.tftpd[25949]: RRQ from 172.16.0.26 filename pxelinux.cfg/44454c4c-3300-1033-8050-abcdef4e3153 Jun 18 06:05:13 boothost in.tftpd[25950]: RRQ from 172.16.0.26 filename pxelinux.cfg/03-03-13-83-83-d3-a3 Jun 18 06:05:13 boothost in.tftpd[25951]: RRQ from 172.16.0.26 filename pxelinux.cfg/AC10001A Jun 18 06:05:13 boothost in.tftpd[25952]: RRQ from 172.16.0.26 filename pxelinux.cfg/AC10001 Jun 18 06:05:13 boothost in.tftpd[25953]: RRQ from 172.16.0.26 filename pxelinux.cfg/AC1000 Jun 18 06:05:13 boothost in.tftpd[25954]: RRQ from 172.16.0.26 filename pxelinux.cfg/AC100 Jun 18 06:05:13 boothost in.tftpd[25955]: RRQ from 172.16.0.26 filename pxelinux.cfg/AC10 Jun 18 06:05:13 boothost in.tftpd[25956]: RRQ from 172.16.0.26 filename pxelinux.cfg/AC1 Jun 18 06:05:13 boothost in.tftpd[25957]: RRQ from 172.16.0.26 filename pxelinux.cfg/AC Jun 18 06:05:13 boothost in.tftpd[25958]: RRQ from 172.16.0.26 filename pxelinux.cfg/A Jun 18 06:05:13 boothost in.tftpd[25959]: RRQ from 172.16.0.26 filename pxelinux.cfg/default Any cluesticks on solving this? For now I've just reverted to 3.35, but it would be nice to get it working with the current release.
