iptables-save output using dotted quad netmask rather than CIDR
by Tim Connors 13 Dec '13

13 Dec '13

iptables-save on rhel5 outputs: -A RH-Firewall-1-INPUT -s 12.3.4.5/255.255.0.0 -p tcp -m tcp -j ACCEPT whereas rhel6 outputs -A RH-Firewall-1-INPUT -s 12.3.4.5/16 -p tcp -m tcp -j ACCEPT Wanting to normalise iptables-save to one form or the other (preferably using the dotted quad netmask), the best I can come up with is a line by line grep (for optimisation perhaps, since a match wont happen often) for /<number> and then extract the number, pass to cidr2mask, and replace /<number> in that line (this is part of a self contained shell script that will be executed on the fly on another host, so I'd rather not rely on anything that isn't already in RHEL, ie no writing a perl sript myself unless it's a one liner perl -e thing). What flag to iptables-save am I missing where it does this for me? -- Tim Connors

gnucash alternatives
by James Harper 13 Dec '13

13 Dec '13

I've been tinkering with gnucash, and the main limitation is that it doesn't support multiuser access. Can anyone recommend an alternative open source accounting package with similar features (needs to support invoicing). Thanks James

hpsa driver and raid expand
by James Harper 13 Dec '13

13 Dec '13

I've just added 2 new disks to my HP server, expanded the array, and then expanded the volume. IIRC the old cciss driver would notify Linux that the device had expanded, but the hpsa driver doesn't appear to be doing this - /dev/sda is still the same size in /proc/partitions? Is there a way to force Linux to reprobe? I know Linux isn't Windows and I'll still need a reboot after expanding the partition (unless that's changed since I did it last?), but I still thought Linux could notice if a block device increased in size... Thanks James

Diomidis Spinellis: The Birth of Standard Error
by Rodney Brown 12 Dec '13

12 Dec '13

http://www.spinellis.gr/blog/20131211/ Earlier today Stephen Johnson, in a mailing list run by the The Unix Heritage Society <http://www.tuhs.org/>, described the birth of the /standard error/ concept: the idea that a program's error output is sent on a channel different from that of its normal output. Over the past forty years, all major operating systems and language libraries have embraced this concept. ...

It would transfer many files (when I only updated one), come up with random transfer errors transferring the files, retry, complain about conflicts with the files it just uploaded (as I only had one client there should not be any conflicts), automatically retry again, and eventually succeed. I see that there is now Owncloud 6.x, so I should try it. It might have improved now. -- Brian May <brian(a)microcomaustralia.com.au>

7 inch android tablet recommendations
by Bianca Gibson 12 Dec '13

12 Dec '13

Hi everyone, My 2012 nexus 7 isn't turning on anymore but is still in warranty. I'll be getting a refund for it pretty soon and may replace it. I was mainly using it for uni stuff, so I'm not sure it's worth replacing now I've finished. I need to think about it a bit more. I liked my nexus 7 apart from it breaking. Something sturdier would be ideal, I won't necessarily break another one with such good timing. Does anyone have the 2013 nexus 7, how are you finding it? The price range I'm looking at is $300ish. Cheers, Bianca

dhcp default route into different routing table
by James Harper 11 Dec '13

11 Dec '13

I have a server with 2 ADSL modems. The server does policy based routing and I do this with ip rule to divert the packets to different routing tables. I'm adding a 4G card (25Mb down, 12Mb up vs 6Mb down and 800Kb up for ADSL) now, and bridging the wwan0 interface into a vlan from a separate device. I need to use DHCP to connect on the 4G card, but I want the default route added into a different routing table. Which of the various dhcp clients is most likely to offer this sort of flexibility? I've never done any more with Linux DHCP than to just configure it and use it... Thanks James

RE: Firefox OS and ZTE phone

Hi Petros. A Samsung Galaxy S2 I use has the following values for the APN configuration: Name: Telstra Internet APN: telstra.wap MCC: 505 MNC: 01 APN type: default,supl All other fields are left "Not set" or at their default settings. Telstra 3G sits in the 850Mhz band. See http://whirlpool.net.au/wiki/mobile_phone_frequencies for details. My (admittedly hazy) memory tells me that Telstra used to do 3G on more than one frequency, but dropped back to 850Mhz only a year or so ago.

USB 4G dongle wwanX vs ttyUSBX
by James Harper 04 Dec '13

04 Dec '13

My preference has been to set up USB dongles in Ethernet mode so they appear as an Ethernet interface, because I suspected that a USB Ethernet interface would be more efficient for Linux than a ppp over ttyUSBx interface. I've always found the wwanX interface more reliable. I have a ZTE MF821 USB dongle that doesn't seem to present such an interface though, or at least it doesn't when I plug it into an OpenWRT router. I can't seem to find any data on which is better though. Does anyone have any evidence or opinion on if it matters? Thanks James
