Betr.: [CentOS] Multiple IP Addresses in a single NIC
by Thom van der Boon 24 Jun '05

24 Jun '05

Hi, You need to issue two commands: /sbin/ifconfig eth0:0 xxx.xxx.xxx.xxx /sbin/route add -host xxx.xxx.xxx.xxx dev eth0 For example: /sbin/ifconfig eth0:0 172.16.1.199 /sbin/route add -host 172.16.1.199 dev eth0 You can even assign multiple aliases to one NIC (One of my servers has about 10 ip addresses): For example: /sbin/ifconfig eth0:0 172.16.1.199 /sbin/route add -host 172.16.1.199 dev eth0 /sbin/ifconfig eth0:1 172.16.1.198 /sbin/route add -host 172.16.1.198 dev eth0 /sbin/ifconfig eth0:2 172.16.1.197 /sbin/route add -host 172.16.1.197 dev eth0 and so on..... You should write an startup script to execute these commands at boot time, because after a reboot the aliases are forgotten.

From: Peter Arremann <loony(a)loonybin.org> > Better believe it - cause that's what they are doing :-) Actually, I can believe it (I just wish that had *1* good option). Tyan's focus is cost and economies-of-scale. You'll find the same of SuperMicro, among a few others. When you start looking at HP and Sun's Opteron designs, then the mainboard cost is only a portion of the system cost. So they are more focus on delivering the optimal solution. Because doing so only affects the end price less than 10%, whereas it might affect the mainboard cost 50%+. > Tyan doesn't lay out that many different boards from scratch... > just look at most of their stuff (S2892, S2885, S2882) - the > CPU/memory area is identical, so all they did was take the old > design, mod around with the chipset and PCI/PCI-X/PCI Express > slots and they got a new one... Actually, other than EMF and the support microelectronics, it's simply a matter of deciding how many traces you want, which may result in more PCB layers. Tyan is really focused on cost. They have an older, "cheap" 2-way Opteron mainboard that doesn't even put DDR channels on CPU #2. And several manufacturers are even worse than Tyan. Especially the non-server focused vendors. SuperMicro and Tyan are better than most. But still not the quality in mainboard design you'll get from select Tier-1 OEMs like HP and Sun. -- Bryan J. Smith mailto:b.j.smith@ieee.org

Missing 4.1 SRPMS?
by James Pearson 24 Jun '05

24 Jun '05

I can't seem to find autofs-4.1.3-131.src.rpm on the download mirrors... I notice that there are not many SRPMS in the 4.1 /centos/4.1/os/SRPMS directory on the download mirrors - is this because most can be found under /centos/4.0/os/SRPMS and /centos/4.0/updates/SRPMS? - or should all the 4.1 SRPMS be in /centos/4.1/os/SRPMS ? Thanks James Pearson

Multiple IP Addresses in a single NIC

Hi all, I've been trying to add a second ip address to one of my network cards in my CentOS box. I've defined the alias on top of eth1 which has become eth1:1 with a different ip address. I can ping the new ip address both from my linux box as well as from my Windoze desktop, however I can only access my Apache web server setup as a virtual host from within the Linux box. If I try to access it from the desktop I get an "Operation Timeout..." error. I'm sure I missed out something really basic.

But given the slew of issues, I just stopped recommending the 9500S until I heard otherwise. -- Bryan J. Smith mailto:b.j.smith@ieee.org

Build scripts for CentOS4?
by James Pearson 23 Jun '05

23 Jun '05

Are there any scripts available for rebuilding CentOS4 - or more specifically rebuilding a custom boot.iso? There is a /scripts directory on the download mirrors, but these scripts are specific to CentOS3/i386 Thanks James Pearson

/etc/init.d/microcode_ctl start /etc/init.d/microcode_ctl: microcode device /dev/cpu/microcode doesn't exist? This is on a clean install from the 4.1 x86 ISO.

Ack, no block diagram in MSI's manual. It's an AMD8131+AMD8111, no HyperTransport tunnel for any video channels. So you can probably assume AMD8111 bridge attached to AMD8131 tunnel to CPU #0. Since there is only one high-speed tunnel, you really can't get more optimal than adding another HT tunnel chip. I guess I'm just looking for the "holy grail" in (2) AMD813x's on a 2-way board. -- Bryan J. Smith mailto:b.j.smith@ieee.org
