Just thought I should mention.. I was wondering why my network was running slowly, and then remembered I'd turned off all the hardware acceleration in my network card while trying to debug the PPPoE issues. Re-enabling them doubled the throughput.

Re: Cross Compile Module for armv7
by Robert Brown 18 May '14

After my recent partial success with this : https://github.com/tmair/DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.… which I am about to d/l and try. Beats me why all of my previous searches for "rtl2832 and kernel 3.4" have not taken me to this possibly vital link. Rob Ok this compile works without errors. Yay (have you any idea how long I have been at this?) and creates a dvb-usb-rtl2832u.ko but not a rtl2832u.ko despite there being a bunch of files like rtl2832u.c and rtl2832u.o and dmesg complains of no frontend: dvb-usb: found a 'RTL2832U DVB-T USB DEVICE' in warm state. [ 2040.777066] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer. [ 2040.793621] DVB: registering new adapter (RTL2832U DVB-T USB DEVICE) [ 2040.833115] RTL2832U usb_init_bulk_setting : USB2.0 HIGH SPEED (480Mb/s) [ 2041.153012] RTL2832U check_tuner_type : ERROR Unknown tuner on board...

Getting there! So the make is running: CC [M] /home/debian/DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0/RTL2832-2.2.2_kernel-3.0.0/rtl2832u.o without errors and similar so should produce a rtl2832u.ko IMHO. I found that the vermagic of the module produced was incorrect - it should be vermagic: 3.4.67-sun4i+ preempt mod_unload modversions ARMv7 p2v8 instead get: vermagic: 3.4.67-sun4i preempt mod_unload modversions ARMv7 p2v8 In trying to track this down I have not found the source of sun4i versus sun4i+. Is it being determined by scripts/setlocalversion by any chance since .config and Makefile look correct. I have attached the .config Makefile and setlocalversion files. Thanks

postfix+dovecot: smtp - pop3 authentication isssue
by Daniel Jitnah 16 May '14

16 May '14

Hi Luvers, Here is scenario (not for me by the way, but someone else) Using laptop with Outlook/Win 7 for client. Mail server is Linux Ubuntu 10.10 (due for upgrade to 14.04 soon) - using Postfix+Dovecot. 1. Able to authenticate to server for smtp and pop using wifi at home and using 3G anywhere. 2. Unable to authenticate in workplace office (talking office building not Office software!!)- keeps asking for username and password when using mail.example.com.au in settings for outlook. (substitute for real domain name of course) 3. Able to authenticate as above if using ip number instead, which makes sense, since in office wifi and mail server on same subnet (192.168.1.X) Why would authentication not work using domain name instead of IP in workplace? This suddenly started about 1 week ago, and has been working fine for months before. Any idea? (I need a clear thinking mind here! Mine is clogged up with all sorts of possibilities... including NSA conspiracy!!) (Before I can tell the user his Outlook/Win 7 is screwed up, I want to eliminate other possibilities. The only thing he says has change is an antivirus software update) Cheers Daniel

gpg question
by Brian May 15 May '14

15 May '14

A program (git-remote-gcrypt) calls gpg like follows: --- cut --- $ gpg -se --default-recipient-self You need a passphrase to unlock the secret key for user: "Brian May <brian(a)microcomaustralia.com.au>" 4096-bit RSA key, ID B9D02636, created 2010-01-13 No such user ID. Current recipients: Enter the user ID. End with an empty line: gpg: Interrupt caught ... exiting --- cut --- gpg complains "No such user ID". Why? It has clearly identified my secret key, so it should be able to find the corresponding public key right? The man page says: --default-recipient-self Use the default key as default recipient if option --recipient is not used and don't ask if this is a valid one. The default key is the first one from the secret keyring or the one set with --default-key. --default-key name Use name as the default key to sign with. If this option is not used, the default key is the first key found in the secret keyring. Note that -u or --local-user overrides this option. Which is what I expected. My ~/.gnupg.conf contains: # FILE CREATED BY SEAHORSE use-agent This is gpg in Debian/wheezy. Is there something I am doing wrong? -- Brian May <brian(a)microcomaustralia.com.au>

building pokerTH for Mageia
by Nic Baxter 14 May '14

14 May '14

Hi I'm trying to build a pokerth for Mageia 3. I've build a number of rpms over time and usually the only problems are dependency ones and a bit of googling solves them. This error is outside of my knowledge and googling skills. Any suggestions on where to start? /bin/ld: /usr/lib/gcc/x86_64-mageia-linux-gnu/4.7.2/../../../../lib64/libcurl.so: undefined reference to symbol 'SSL_get_error' /bin/ld: note: 'SSL_get_error' is defined in DSO /lib64/libssl.so.1.0.0 so try adding it to the linker command line /lib64/libssl.so.1.0.0: could not read symbols: Invalid operation collect2: error: ld returned 1 exit status make[1]: *** [bin/pokerth_server] Error 1 make[1]: Leaving directory `/home/nic/rpmbuild/BUILD/PokerTH-1.1.1-src' make: *** [sub-pokerth_server-pro-make_default-ordered] Error 2 error: Bad exit status from /var/tmp/rpm-tmp.T9Rxda (%build) Cheers Nic

hearts
by Tim Connors 13 May '14

13 May '14

Following on from Russell's talk, to further enlighten you, here is a useful description of the hearts bleeding: http://abclocal.go.com/wls/story?section=news%2Fiteam&id=9526738 'Heartbleed. The term comes from the communication between two so-called "hearts" on a server which verify your security as you shop, check e-mails and bank statements. There is now a backdoor break-in between those hearts, and it's bleeding.' -- Tim Connors

Read Only FS on USB stick
by Andrew Greig 13 May '14

13 May '14

Hi All, I recently copied some files onto a USB stick, but now, I cannot delete them from the stick as the fs is readonly. I have tried to chmod, but no luck. I have tried to chmod as roo, still no good. Then I remembered that the fstab sometimes mounts removable devices readonly, but the only drives referenced in fstab are the swap, / and /home partitions. Where would I be able to change the permissions for this drive, please? OpenSuse 13.1 Andrew Greig

screen resolution mismatch
by James Harper 13 May '14

13 May '14

I'm just setting up a new PC and the native resolution for the display is 1440x900. All the logfiles say the selected resolution is 1440x900, the screen configuration under gnome says 1440x900, but the display itself complains because the resolution is set to 1600x900, and there is about half an inch to the right that is off the screen. Any ideas? I guess I'll tinker with timings unless there is another easy fix...

Automatic Storage Configuration Documentation
by Huw Davies 13 May '14

13 May '14

Hi, I’m in the process of building a number of somewhat more complex Linux (Centos) SAN based environments. I need to document the storage layout (from the physical disk layout right through to the filesystems in their various volume groups) and hoped someone had a pointer to a tool that could produce nice, preferably HTML, documentation automatically. I have in the passed used a tool on AIX that did almost what I needed but adopting it for Centos would be very challenging (especially as it was written in Perl and I’m more of a Python guy).

Cross Compile Module for armv7
by Robert Brown 11 May '14

11 May '14

Hi A variation on a previous query: Can anyone make sense - or better still a process - out of this thread: http://www.cubieforums.com/index.php?topic=2427.0 My responses are authored CarryOnRewardless. The DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0-master folder contains source files for a module I need rtl2832.ko and some other related ones. I need to compile it for a 3.4 kernel on a sun4i armv7 platform so I get the kernel source from github sunxi. But running make ARCH=arm -C /home/user/linux-sunxi/ M=$PWD from folder /home/user/DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0-master gives errors suggesting it could find no Makefile in the linux-sunxi folder but it is clearly present. make: Entering directory `/home/user/linux-sunxi' scripts/Makefile.build:44: /home/user/DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0-master/Makefile: No such file or directory make[1]: *** No rule to make target `/home/user/DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0-master/Makefile'. Stop. make: *** [_module_/home/user/DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0-master] Error 2 make: Leaving directory `/home/user/linux-sunxi' I am obviously doing something fundamentally wrong but I cannot see it atm. Any ideas?
