SAS/SATA DAS
by Joseph L. Casale 03 Sep '08

03 Sep '08

I need to replace a slow HP MSA20 that's a bottleneck right now (We are an HP shop). HP's only option with 3.5" SATA drives is stuck at SATA I behind a SAS controller. Dell makes an MD1000 that claims SATA II speeds behind a SAS Perc 5/E (Don't know anything about dell). Anyone got any real world info they can share? I need 3.5" SATA II at least 12 drives behind SAS, I am not concerned about space and could use multiple 1u chassis if I had to. Thanks! jlc

vtun -- no IPv6 support?
by Robert Moskowitz 02 Sep '08

02 Sep '08

Reading many comments about vtun available through google searchs seems to imply it supports IPv6. When I install it (v 3.0.2-1) and bind it to an interface that does NOT have IPv4 defined (only v6), start the service, and do a 'netstat -nat|grep 5000', I see it bound to 0.0.0.0:5000, not to the IPv6 0::/128 equiv address. What gives? IPv6 support or not? Meanwhile I found the kame vtun: http://orange.kame.net/dev/cvsweb.cgi/v6tun/?cvsroot=apps And was given the following 'changes' to compile it on linux. Do I need this??? v6tun: v6tun.o gcc v6tun.c v6tun.h -o v6tun install: v6tun -rm -f $(install_dir)/v6tun install -c -o root -g wheel -m 04710 v6tun $(install_dir) clean: 6tun: v6tun.o -rm -f *.o v6tun gcc v6tun.c v6tun.h -o v6tun install: v6tun -rm -f $(install_dir)/v6tun install -c -o root -g wheel -m 04710 v6tun $(install_dir) clean: -rm -f *.o v6tun

small window manager
by Paul Bijnens 02 Sep '08

02 Sep '08

What is an alternative X window manager, supported by CentOS, that has very small memory footprint? I want to avoid twm, because it defaults to interactive placement when not giving geometry options.

NFS static ports configuration
by admin 02 Sep '08

02 Sep '08

A couple of RHEL5 books I'm reading at the moment suggest port numbers above 1024 for statd, lockd, mountd and rquotad (eg 38001-38006 or 32764-32767) when configuring NFS to work with a firewall. The default /etc/sysconfig/nfs on CentOS5 however has defaults under 1024, such as mountd 892 statd 662 rquotad 875 Is there something security-related going on here that I'm not aware of, or some other explanation? Neither text mentions the use of ports under 1024 at all. Thanks Mick

Help using ed [OT]
by Thomas Johansson 01 Sep '08

01 Sep '08

Hi Perhaps omeone might answer this tricky problem. I can do this other ways, but i really want to understand how to solve it using ed. I have one solution using g/re/s/re//txt/ , but I want to understand how or if i can solve it using the ed (.)a command. A script i have parse several files and append text after a specific text is matched. If one file do not have this text, i get a no match and the script terminates. How can I avoid this behavior keeping the original coding style for ed and append text. I have tried tried but still cannot get it correct using (.)a. Is it even possible to do it that way using the (.)a command? Thanks in advance Thomas code example that give a "no match". Fairly easy to read and understand example 1: ----------- for RFILE in $RLIST; do ed - RFILE <<- EOF H /\[matching_text_1\]/a This is the appended textline(s) for text1 . /\[matching_text_2\]/a This is the appended textline(s) for text2 . w q EOF done Another example that solve the above problem. But this example become very easy unreadable if the appended text is long and/or includes linebreaks. Example 2: ---------- for RFILE in $RLIST; do ed - $RFILE << EOF g/text1/s//text1\\ appended_text1/g g/text2/s//text2\\ appended_text2/g w EOF done
