Q: Ubuntu ARP reply configuration

12:51 AM

I am wondering what/if there is any configuration that enables arp replies. I have an Ubuntu machine with two interfaces - one is ethernet to a non-public LAN, the other is Wifi which connects to the public internet. I need internet access on the private LAN for one computer temporarily, so I se...

Q: How shall I create a physical volume from a partition containing `/`?

I have a laptop running Lubuntu 18.04, with a single hard drive as a bootable disk, and two partitions on it: EFI System Partition and a bigger partition contains everything else (e.g. / an /home). $ sudo parted -l Model: ATA TOSHIBA MQ01ABF0 (scsi) Disk /dev/sda: 500GB Sector size (logical/phy...

I'm running Ubuntu 18.04.1, everything is up-to-date, just now I ran into a printer issue. When I went to print a color document, (HP OfficeJet 4500) the colors seem to be reversed, and the entire background is cyan. This has never happened before, I've done lots of color printing. Printer test page is fine, I re-started both the printer and computer. Has anyone else run into this? B&W prints fine

Hello, everyone

Any ubuntu expert up here who can help me with recovering my database file over SSH

@JProgrammer I don't think that's allowed here...

Which database? How did you delete it?

says he used rm

He's screwed without physical access anyway unless he has a backup.

@JProgrammer if you have multiple partitions or drives you might be lucky getting some files back with testdisk/photoresc but since you need to install that the chances re really pretty slim, if you have no backup you can assume that you're screwed as @fabby said. If you're heavily relying on that database you only can send it in for data recovery which will be hard - impossible if you have no physical access to the machine and a crappy provider support.

You might call them if they have a backup maybe, some providers, especially smaller ones do that to protect their customers from hardware related data loss.

@SergiyKolodyazhnyy are you maybe able to translate that => askubuntu.com/q/1120568

Ugh, I was going to write an answer in Russian and English, but I am missing russian input and I just removed other locales to save disk space yesterday

talking about perfect timing

oh yeah :)

anyways the quesition got closed pretty quickly

Right . . . Well . . . It could have been useful . . .

yes i mean the two answers existing adress it a little bit but there could have been more information right in this place

I may now sound stupid, but, is the amount of forks a forkbomb produces limited by ulimit -n too?

10:14 AM

I think I broke my brain just now

I haven't typed in Russian for a very long time, and trying to write answer in both English and Russian felt like I was learning ice skating

@Videonauth Um yes, however users with admin capabilities such as root can still do whatever unix.stackexchange.com/a/85441/85039

oh ok just wondered how much i compromise my system if i set the ulimit for the user higher than the 1024 he has, some games need a higher number to run under wine/proton

I may be mistaken, but number of processes itself isn't the problem. Problem is that each process consumes certain amount of RAM.

Smoke and bedtime. I think that question made me tired.

well on my old system the ram wasnt the problematic part, here on my new one even less (with now 32 GB RAM) it mostly run in a bottleneck at cpu level as opening and forking takes processing power as well

but well back then i have run that experiment on a vm and with only 2 cores

Q: Are these two ways of installing Lubuntu with LVM both feasible and equivalent?

-1

When installing Lubuntu, there is a step asking (see the picture below, although it is for Ubuntu not for Lubuntu) “Erase disk and install Lubuntu”, which has two suboptions: "Encrypt the new Lubuntu installation for security" and "Use LVM with the new Lubuntu installation"; “Something Else” ...

Q: Should we close bug related questions -in all cases-?

The story starts on a (this) Saturday afternoon, finding myself trying to print something. Out of the printer comes a pretty blue piece of paper. I am pretty sure the blue is not coming from one of my creative burbs, so, I am looking up on AU what could be the cause. And: yes! it is an existing ...
