Re: [CentOS-docs] Broadcom's BCM4311-, BCM4312-, BCM4321-, and BCM4322-based hardware install manual
OK then, I'll take your sillence as an approval of the manual and remove the DRAFT tag and move it to *Making Wireless work on your laptop (or desktop) *So if anyone has any final suggestions or comments I'd be happy to hear it before this goes official. Sorry, for not testing sooner. I took some time this morning and could update my driver using the latest kernel update! Here are my comments: 1. There is a typo in: mkdir -P /usr/local/src/hybrid-wl mkdir takes the -p option (lower case) 2. I could not perform: modprobe wl.ko but: insmod wl.ko works 3. I did not need to define all the aliases, neither remove all b43 stuff (I'm on a CentOS x86_64) Since I prefer not to diverge too much from the base system, I left it like that. 4. Interestingly I tried to define TYPEDEF_BOOL via the command line (which would avoid the modification of the files): make -C /lib/modules/`uname -r`/build/ M=$BUILD_DIR MODFLAGS=-DTYPEDEF_BOOL It builds without error, and the module can be inserted, but then it is not working (wlan networks are not found) More generally my question would be: if we would automate this procedure in a RPM (including the download from Broadcom website), would it count as redistribution?? Please find below for reference the script and patch I used for my testing. (please note: that the module is built in a temporary directory in order to keep the source directory read-only) Thanks for the hard work!

[CentOS] advanced routing, 2isp
Guys, please I have no luck with this. I have 2 ISPS. I have working configuration with ip route a 2 routing tables in a way, that matching local subnet uses second provider while all the others are using the first one - main. The main problem I am having is, that I am unable to reach my router via public ip address of that second ISP. This is my default routing table [r...@sx1 cron.hourly]# ip route show table main 194.228.196.39 dev ppp0 proto kernel scope link src 90.178.76.117 10.123.50.101 dev ppp2 proto kernel scope link src 10.123.50.1 10.123.50.100 dev ppp1 proto kernel scope link src 10.123.50.1 213.194.242.0/24 dev eth1 proto kernel scope link src 213.194.242.198 10.123.20.0/24 dev eth0 proto kernel scope link src 10.123.20.1 10.123.10.0/24 dev eth0 proto kernel scope link src 10.123.10.11 10.123.11.0/24 dev eth0.8 proto kernel scope link src 10.123.11.1 10.123.42.0/24 dev eth0.5 proto kernel scope link src 10.123.42.1 10.123.123.0/24 dev eth0.7 proto kernel scope link src 10.123.123.1 10.123.40.0/24 dev eth0.4 proto kernel scope link src 10.123.40.1 10.123.30.0/24 dev eth0 proto kernel scope link src 10.123.30.1 10.123.44.0/24 dev eth0.6 proto kernel scope link src 10.123.44.1 169.254.0.0/16 dev eth0.8 scope link default via 213.194.242.1 dev eth1 As you can see , my default provider has gateway 213.192.252.1 , connected via eth1 . This works fine for me. Second configuration is ip rule based, when subnet 10.123.123.0/24 goes to routing table adsl [r...@sx1 cron.hourly]# ip rule show 0: from all lookup 255 32764: from all fwmark 0x1 lookup adsl-vpn 32765: from 10.123.123.0/24 lookup adsl 32766: from all lookup main 32767: from all lookup default [r...@sx1 cron.hourly]# ip route show table adsl 194.228.196.39 dev ppp0 scope link src 90.178.76.117 10.123.123.0/24 dev eth0.7 scope link src 10.123.123.1 default via 194.228.196.39 dev ppp0 As you can see in this case, all trafic goes via ppp0 (my second internet provider connected via ppp0 - adsl ppoe). This works fine. What I want to achieve is, now being able to ping /access/whatever to my server via second public IP address of my adsl provider (90.178.76.117). To achieve this i have added iptables rule, which marks all packets comming via ppp0 (iptables -t mangle -A PREROUTING -i ppp0 -j MARK --set-mark 0x1). And created another routing table named adsl-vpn [r...@sx1 cron.hourly]# ip route show table adsl-vpn 194.228.196.39 dev ppp0 scope link src 90.178.76.117 10.123.10.0/24 dev eth0 scope link src 10.123.10.11 default via 194.228.196.39 dev ppp0 Now i have added ip rule, which for all packets marked as 1 , which are the ones which came trough ppp0 = my second ISP, uses table adsl-vpn [r...@sx1 cron.hourly]# ip rule show 0: from all lookup 255 32764: from all fwmark 0x1 lookup adsl-vpn --- this one 32765: from 10.123.123.0/24 lookup adsl 32766: from all lookup main 32767: from all lookup default Well, now I should be able definitely to ping my server from outside, but it does not works Pinging from windows machine in outside world : C:\Users\bossping 90.178.76.117 Pinging 90.178.76.117 with 32 bytes of data: Request timed out.

There are freely redistributable, but still they aren't published by
upstream. You
can use these instead:

but
there are a lot of problems with any windows 64 bits. And another problem,
a big
really, is that you can¡t install a windows kvm guest directly to a virtio

First you need to install to an ide disk, after generate a virtio disk and
attach to
win guest, install the virtio driver and last remove ide drive ... very
very ugly.

You know your right. I don't know what I was thinking, a rotation is a
rotation and if it takes 4ms on the outer tracks then it takes 4ms on
the inner tracks.
It is I who had to two mixed up. It would be CLV that would make the
disk spin faster as it approached the inner tracks which is the only
way rotational latency would decrease.

[CentOS] CentOS 5.4 Upgrade installation failure
CentOS 5.3 has been running fairly good except for a slow ethernet connection so I thought I would upgrade to CentOS 5.4 to see if that improved things. I had previously changed fstab and menu.lst to use UUID instead of LABEL in order to insulate myself from partition label changes I wanted to make. This worked fine in CentOS 5.3. When I attempted to upgrade from 5.3 to 5.4 using the installation disk and telling it to upgrade rather than do a new install, the installation correctly found my root partition as /dev/sdb8. When I proceeded with the upgrade I received the error: Error mounting device UUID=cee298a0-9c47-4a3a-ac84-23db4d20edd5 as /. No such file or directory. This most likely means the partition has not been formatted. But of course it has been formatted and is my / partition running CentOS 5.3. Does anyone know how to fix this to get CentOS 5.3 upgraded ? Do I have to use LABEL in fstab and menu.lst for my partitions, or perhaps just for my root partition ?

no, I'm not. most HD's ('green drives' complicate this some) spin at
a constant RPM, so the rotational latency is the same on the inner and
outer tracks, an average of 1/2 turn, about 4mS for a 7200 rpm drive,
and 2mS for a 15000rpm enterprise drive . However, the data rate
changes. so the outer tracks have more data on them, which is read at a
higher speed in megabytes/second
That's why in ancient times one was setting up partitions so that the
swap area was the the beginning (mostly the outer tracks of the HD --
never hit a drive that did it the other way round) of the drive.
Try it yourself, get a spare HD and create three partitions on it, two
smaller ones at beginning/end of the drive, the third one filling the
gap between them; install bonnie++ and compare the transfer rates.
But these days, nothing should ever be reading from swap, although you
might write a bit there. If it does, buy some more RAM instead of
worrying about disk performance.
Sure, absolutely no question; *but* in the (ancient) times it was
important, it was 'nice' to have it as fast as possible, i.e. on the
fastest section(s) of the used HDs. So...

So... unless you're using tmpfs, where your swap space doubles as backing store for your /tmpI use this quite regularly on solaris, it performs much better than a conventional journaled file system, as recovery from system crashes is totally not a priority. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
