[opensuse] RTL8812AU woes - now "works" but some things hang
by Mikhail Ramendik 20 Dec '17

20 Dec '17

Hello, Well, while I was trying to get a tcpdump output. the RTL8812AU thing started working. Sort of. It got an IPv4 address. Then after a reboot pings started working. That may have been caused by me retyping the WPA-PSK password, or not. However, not all is well. While pings are stable, some network transactions just hang. Google Mail gets mysteriously stuck at "still working" and zypper gets stuck at a download that, actually, works fine with wget. I even created a thread on zypper but then realized it might be the card, and it was. Of course I tried lowering MTU but it just won't lower MTU. Using yast, I set it to 1400 in the /etc/sysconfig editor (then rebooted), and it is also at 1400 in the network settings editor, but it is still 1500 in the ifconfig output. So I reverted to the old 2.4Ghz card which also has an MTU of 1500 but everything works right. How can I troubleshoot this now? If the dongle is broken, it's broken in a very strange way. And anyway a lower MTU *should* help, because pings work - but I can't lower the MTU and that is certainly not a hardware issue. -- Yours, Mikhail Ramendik Unless explicitly stated, all opinions in my mail are my own and do not reflect the views of any organization -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

If you have a 4KB drive it is best to ensure it doesn't do an optimization for aligning with the old practice of starting the first partition on sector 63. I've never seen one that supported the sector 63 alignment, but I understand those that do have a jumper to control it.

[opensuse] Wi-Fi dongle not getting IPv4 address
by Mikhail Ramendik 19 Dec '17

19 Dec '17

So I thought it was the RTL8812AU driver, but now I used a version tested by Linux Kamarada of this list (thanks!) and I am still having the problem. I have a new Wi-Fi dongle (5 GHz/2.4GHz, wlan1) as well as a PCI card (2.4 only, which is why I want to use the new dongle; wlan0). I configure both with wicked in yast. Unfortunately, while the new dongle appears to connect to the wireless network, it fails to get an IPv4 address and no communication happens. After ifdown wlan1 and ifup wlan1 , I see "setup-in-progress". The only stuff added in dmesg at ifup wlan1: [ 1525.360875] cfg80211: Regulatory domain changed to country: GB [ 1525.360878] cfg80211: DFS Master region: ETSI [ 1525.360878] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp), (dfs_cac_time) [ 1525.360882] cfg80211: (2402000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm), (N/A) [ 1525.360884] cfg80211: (5170000 KHz - 5250000 KHz @ 80000 KHz, 160000 KHz AUTO), (N/A, 2000 mBm), (N/A) [ 1525.360886] cfg80211: (5250000 KHz - 5330000 KHz @ 80000 KHz, 160000 KHz AUTO), (N/A, 2000 mBm), (0 s) [ 1525.360887] cfg80211: (5490000 KHz - 5710000 KHz @ 160000 KHz), (N/A, 2700 mBm), (0 s) [ 1525.360889] cfg80211: (57000000 KHz - 66000000 KHz @ 2160000 KHz), (N/A, 4000 mBm), (N/A) iwconfig and ifconfig outputs, which show the problem: # iwconfig wlan1 wlan1 IEEE 802.11abgn ESSID:"Ramendik_44_5Ghz" Mode:Managed Frequency:5.18 GHz Access Point: 70:50:AF:CC:3B:05 Bit Rate=867 Mb/s Tx-Power=12 dBm Retry short limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=36/70 Signal level=-74 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 # ifconfig wlan1 wlan1 Link encap:Ethernet HWaddr 00:0F:00:37:B8:6D inet6 addr: fe80::20f:ff:fe37:b86d/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:871 errors:0 dropped:670 overruns:0 frame:0 TX packets:72 errors:0 dropped:78 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:81082 (79.1 Kb) TX bytes:11537 (11.2 Kb) When I look into the admin interface of the router, I actually see this device listed under the IPv6 address. But normal communication is IPv4 and that does not work. I tried to set "DHCP version 4 only" for this interface in yast, this does not change anything. Unfortunately, the router does not let me disable its "Enable IPv6 DHCP server" setting. This is also not some incompatibility of the router with Linux. A laptop that runs Fedora (with the iwlwifi driver for its built-in WLAN) connects to the same 5GHz network just fine. So how do I make wlan1 use IPv4 as normal? And are there any other logs I should look at? Of course this is a new dongle ordered from China, so there is a chance of a hardware failure. But this looks like a strange kind of hardware failure? Or should I suspect one? I do have a Windows 10 machine, so if I have no other option I can try and set the dongle up in that machine just to see if it works. But I'd rather resolve my problems just with Linux. -- Yours, Mikhail Ramendik Unless explicitly stated, all opinions in my mail are my own and do not reflect the views of any organization -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] multiboot vis-a-vis /boot/efi/EFI/opensuse
by Felix Miata 19 Dec '17

19 Dec '17

Neither https://en.opensuse.org/openSUSE:UEFI nor anything I've found so far suggests how to multiboot multiple releases of the same distribution. I see I can create new entries with efibootmgr, but can each openSUSE installation ever use the same /boot/efi/EFI/opensuse/, or does each need its own directory with unique names? Do I create a new entry for the first after renaming the original (TW20171214 is already installed), or after copying the original to a new name? Does the Grub that actually does the work on a / partition need to be reconfigured with a unique directory name in /boot/efi/EFI/? Nothing was evident in the bootloader phase of TW installation to address EFI directory naming. My ultimate expectation is to EFI boot more or less the same way as with Legacy Grub and MBR, with a main boot menu I configure on a partition not managed by any installed distro, possibly rEFInd or AiR-Boot, and each distro's own bootloader configured by it to exclude any other installed distro (os-prober disabled). With EFI, I anticipate efibootmgr to be sufficient to the task at least initially. -- "Wisdom is supreme; therefore get wisdom. Whatever else you get, get wisdom."

[opensuse] Does iperf3 work???
by James Knott 19 Dec '17

19 Dec '17

I installed iperf3 on my desktop and notebook computers. When I run it as a server on my desktop, it displays a text box that say server listening on 5201. I then run it as a client on my notebook computer. After a while it times out saying it can't reach the server, even though pinging the same address works. When I run Wireshark, I don't see any traffic from iperf3. Any ideas? tnx jk -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Running Ubuntu bins on openSUSE
by Roger Oberholtzer 18 Dec '17

18 Dec '17

(I think this is a libusb question). I am trying to run some Ubuntu 16.04 binaries on openSUSE Leap 42.3. I have added whatever Ubuntu libraries are different (based on names) to a directory on openSUSE. I can actually run quite a bit. The software is an SDK for high-speed USB3 cameras from Flir (formerly Point Grey). I can run a QT GUI as well as simple command line programs to try to access images from the cameras. The applications talk to the camera. Everything works except getting an image. In strace I see that it is in a futex waiting and waiting. I have obviously been in contact with Flir support. But we are none the wiser. Saying that you are not running Ubuntu is pretty much the same as saying that you are not running Windows... I do not know that the issue is in libusb. I do not have the source (or it would not be a Ubuntu app...). I can only guess that it is since that must be how the SDK gets images. I have tried the standard openSUSE libusb as well as the one for Ubuntu. It makes no difference. Anyone have any experience running Ubuntu binaries on openSUSE? It seems it is so close to working. But close is not good enough. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org

[opensuse] Get an SSD just for swap?
by Mikhail Ramendik 18 Dec '17

18 Dec '17

Hello, I have a 8Gb Pengium G2120 system with a normal WD Red 3 TB hard drive. Most of the time it actually does what I want just fine. Unfortunately, sometimes it starts to swap and then becomes very slow immediately. I tried reducing swappiness to 10, now it starts to swap in less cases - but when it does it basically hangs for a few minutes. I can't afford a full upgrade (CPU. Mobo, RAM), especially with current RAM prices. And I am not sure I should spend money on more DDR3 RAM now, especially since I am not exactly sure if what I have is DDR3 or DDR3L and how new additional RAM will affect the system. So I wonder - would it help to get a small (16-32G) SATA SSD and use it just for swapping? As this is for swap only, I can get a cheap SSD (if it breaks I just lose one session). I can get a 32Gb SSD for about 25 Euro, while an extra 8GB of RAM would apparently set me back more like 50 Euro. But will this work? -- Yours, Mikhail Ramendik Unless explicitly stated, all opinions in my mail are my own and do not reflect the views of any organization -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse+owner(a)opensuse.org
