Hey y'all,

I have got some observations and naive questions regarding local dns and local dns like fuctionality of unifi network sdn.

I have been debugging this on my network last week and I am wee bit confused. Think of it of as angrily confused storytelling :)

While I understand unifi network does NOT offer dns server as part of its functionality, it offers integrated dhcp server, dnsmask, dns caching and some internal glue code, thats pretty damn decent *(when it works) and covers most of the usecase people like me are probably looking for:

  • internally available address or fqdn for devices on the network, if internal domain name not set, the adrress usually equals hostname/ or hostan

TLDR: Do truenas jail require specific virtualization/ server features on NIC to work properly? There is little real world information regarding AQ105 and AQ107 based NICs.

Since it christmad time, I finally got time to play around with QXG-10G1T NIC and mikrotik CRS305-1G-4S+IN + two S+RJ10 sfp modules.

Changing network uplink from onboard intel GBE to aquantia worked without problems, just needed to enable driver via tunable and change dhcp reservation to new nic mac address. Networking wise and performance wise everything wa

Update: Got second second dose two days ago and surprise - no major side effects or discomfort, besides slight muscle pain. Still pissed about lack of information, but if you are hesitating, go for it.

Hello everyone a thanks for stopping by, I would like to ask for second opinion on whether I should avoid getting second dose of Astra Zeneca vaccine.

Why am I asking? There is little official information available beyond the most serious side effects (blood clots etc.) and vaccination program in my country is very inflexible. That combined with my unusually strong reaction to this vaccination makes me very uneasy.

To describe the situation, I am 34y old male (overweight but not com

Mikrotik newbie here.

We have got batch wap ac units to replace aging public access points in our bulding. Winbox was suprisingly pleasant, but to our suprise l2 autodiscovery doesnt work over ethernet port, so we have to do initial setup over wireless (why?).

Our setup is pretty simple, since filtering and routing is done elsewhere, mikrotik aps work as simple bridges - so no firewall rules, nat, dhcp server etc. Just adding eth to bridge interface, setting static ip for management and securing access and we are done.

Trouble is, should we need to reset the device, it cannot be configured remotely over network. Someone has to go hunting the ap with notebook. Is there a way around thi

I have performed standart dnf system upgrade from Fedora 28 KDE spin ton 29 beta. Aside from removing some unnecesary packages, process went perfectly well.

Device is Dell XPS 9560, with originial qualcomm killer 1535 replaced by intel 7265 wireless card.

After first succesful boot, I have noticed that Network Manager applet did not pick up wireless card at all, only wired connection.

After checking through deprecated ifconfig -a and current ip link , corresponding interface wlp2s0 was down.

Manually turning interface up by ip link set dev wlp2s0 up produced no errors, but interface stayed down.

I have checked dmesg and journal, there are no errors or oddities. Fi

Given that note everyone has access to VAR and publicly available information about available hardware can be flaky, documentation like Product Specifications Reference(PSREF) from Lenovo is incredibly handy for fact/checking and similar tasks.

I was hoping other large vendors might publish similar compendiums, but so far I found nothing. Does Dell , Hp et al. have anything like that?

Given that VAR representatives frequent these forums, I hope this isn't wrong place to ask.

Hi,

after playing around with cool-old-term (reddit presentation here), I have packaged the app with provided specfile and tried to set up copr repo for ease of use.

The thing is, I can't upload srpm since I don't own or have access to server of my own and copr doesn't allow maual file uploads.

Any idea what should I do?

I,ve just got zenbook ux32ln (haswell/nvidia based ultrabook) and ran into some unexpected issues while setting up fedora 20.

For some reason xotg ran in software accelerated mode, even though i915 module was loaded. Poking through logs eventually shown that /dev/dri/card0 was missing.

Eventually, I enabled uefi-csm (bios compatibility mode) in uefi/bios and lo!, all problems disappear.

Question is why?

I have been encountering strange bug with all 3.13 kernels, whenever I move mouse cursor beyond certain area, it disappears. It is still functional, just invisible. I am attaching screenshot for illustration - "area of invisibility" denoted by red stripes. Imgur

I am runnning plain x64 Fedora 20 with KDE on Zenbook UX31A.

Triggered by Intel fastboot (i915.fastboot=1 in kernel parameters). Shown in dmesg as:

I have been recently experiencing systemwide stutter a freezing during file opperations, namely when I was copying large files from host drive to usb flash drive and vice versa.

At first I thought that ntfs-fuse was at fault, but cpu usage was low and reformatting to exfat didn't help. When I noticed that system stutters, albeit very sligthly, when I copy large files around in my home directory, I started investigating.

Cause of the stuttering is very high iowait, observed through top. Iowait rises to 60-80% during heavy stuttering and hovers around 30% during slight stuttering. Once file operation is complete, system returns to normal within seconds.

Dmesg and journald show n

Brief:
Fedora can no longer be booted -> drive is supposedly no longer bootable (Imgur). Widows installation is not affected. Problem fist appeared after drive hosting fedora installation had been removed removed and system was booted into Windows. Drive was later reconnected to the same sata port, and seems to be working perfectly.

I suspect that UEFI is at fault somehow, but I have no idea how to fix the issue. Has anyone encountered similar problems?

Background information:
I have been running dual boot of Windows 8 and Fedora 19 on desktop workstation for about three months. Windows was installed first, second drive was added

I am trying to automate testing of 20 files on various combination of options. Since bash doesn't do nested arrays, I am using 4 variables instead of two:

$typ , declaring what kind of test is to be performed
$task, containing filenames $optimum, containing numerical value associated to a specific filename
&ncity, containing numerical value associated to a specific filename

If it were possible, I would just use $task containing ordered sets like this {{filename1,optimum1,ncity1},{filename2,optimum2,ncity2},...{filename20,optimum20,ncity20}}.
Also some test require different parameters so I have used case to discriminate between them and call modified loo

Question: I am somewhat confused how Fedora handles libraries - like what are the default locations, enviroment variables that that store additional locations et cetera. Does anyone know whats what?

Background: I am using Fedora 18 x64_86 and I have just installed Gurobi optimizer with R interface. Installation was mostly manual, as the developer distributes zipped binaries and user extracts software to a chosen location, exports $GUROBI_HOME to $PATH and $GUROBI_HOME/lib to LD_LIBRARY_PATH. As result, gurobi should be callable from the shell and its shared libraries should be easily discovered by other software.

I intend to us Gurobi (x86_64) in conjuction with R (x86_64), which
