Hello: New to linux, and Centos. Can I plug thumb drive into computer, and download Centos directly to thumb drive, then move thumb drive to another desktop and use it like a "live CD" to install it on that computer? Thanks for any help. Tom

I am running on the Centos 6.5 x86_64 boot disk. # uname -a Linux localhost.localdomain 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux I have been running ddrescue for a while and now it is time to check the progress. I want to take the oldhd.img output from ddrescue and load it to satrt performing recovery (LVM, then filesystem) but I want to do a copy on write with that. I fetched http://www.atcomputing.nl/Tools/cowloop/packages/cowloop-3.2.0.1.tar.gz, built it root@localhost ~/cowloop-3.2.0.1 # cowdev -a /root/oldhd.img /root/oldhd.cow Cannot open /dev/cow/ctl: No such device or address So I: root@localhost /dev # mkdir cow root@localhost /dev # cd cow/ root@localhost /dev/cow # mknod /dev/cow/ctl b 241 255 But I still get a root@localhost ~ # cowdev -a /root/oldhd.img /root/oldhd.cow Cannot open /dev/cow/ctl: No such device or address Listing /proc/devices I do not see 241.

Dear all, I would like to know how I could run my dongle wifi TP-Link (Ref: TL-WDN4200, version 1) under Centos 6.5 (Final). Should I create by myself the corresponding driver or does exist another way? When I ran lsusb I got: Ralink Technology RT3573 Wireless Adapter Thanks for your help. Regards, Eric

OT: Linksys router misbehaviour
by Timothy Murphy 26 Aug '14

26 Aug '14

I'm running a Linksys WRT54GL router from my CentOS-7 home server. Every now and then (maybe once every 2 days) the router's WiFi cuts out, and I've found no way to solve this except to disconnect the power from the router, wait 10 seconds and then re-connect. This always works. The router is running under dd-wrt. My question is - which makes it a tiny bit CentOS-related - does anyone with such a router know of a way to wake the router up in such a case through the computer? I wouldn't have dared to ask this question here or anywhere until recently, as I assumed my ancient Linksys routers were obsolete. But I've been reading posts recently saying that there hasn't really been a Linux router to replace the WRT54GL, and in particular Linksys's recent 11n replacement is not as good as the old model in many ways. Anyway, if anyone has an answer to my query I should be very grateful. I have a couple of IP cameras working by WiFi on the computer, which I can look at remotely. I've connected one by TP-Link through the router, and this doesn't cut out, but it is not wholly satisfactory. But this shows that the router is alive and well, only its WiFi side is failing. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

ipset module loaded at startup on CentOS 6.5
by Rob Townley 26 Aug '14

26 Aug '14

Anybody on here successfully get ipset iptables sets to work _after_ a reboot? My question on StackExchange http://unix.stackexchange.com/questions/149536/upon-bootup-all-iptables-are… Some of the things that need to be in place, otherwise iptables does not load: 1.) The kernel module ip_set needs to be loaded. 2.) The "sets" need to be created. 3.) Only after 1 and 2 succeed, dare start up iptables.

Postfix setup
by Timothy Murphy 25 Aug '14

25 Aug '14

I'm trying to clarify the various ways in which I could set up Postfix + Dovecot + SpamAssassin under CentOS-7, and I'd welcome any comments on the following remarks. As far as I can see there are 3 standard ways of setting this up: 1. Use amavisd 2. Use dovecot + pigeonhole/sieve 3. Use spamass-milter At present I'm following (2), but am thinking of going over to (1), since this seems simpler. (Amavisd wasn't available when I set up CentOS-7, so I didn't consider it then.) It seems to me that (2) is using dovecot in a slightly odd way, since as far as I can see dovecot normally takes email from ~/Maildir/cur/ and then moves marked spam. I'm not quite sure if (3) is a genuine alternative, or if it is why it is not the standard since it seems very simple? -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland
