networking – libvirt on fedora, qemu/kvm guest, guest can ssh to host, but failed to samba or ftp to host

I am running libvirt/qemu-kvm on Fedora32, guest OS is win10 with spice-guest-tool in use.

I use ‘nat’ mode virtual networking.

root@fedora ~)# virsh net-dumpxml default
<network connections='1'>
  <forward mode='nat'>
      <port start='1024' end='65535'/>
  <bridge name='virbr0' stp='on' delay='0'/>
  <mac address='52:54:00:e1:1e:c3'/>
  <ip address='' netmask=''>
      <range start='' end=''/>

While guest is running, ‘brctl show‘ seems fine.

(root@fedora ~)# brctl show
bridge name bridge id       STP enabled interfaces
virbr0      8000.525400e11ec3   yes     virbr0-nic

On host I can ping guest by its ip (

On guest, I can access internet, also can ssh to my host,
but failed to access samba and ftp on my host.

For example, I type ‘net view‘ on guest,
host ‘tcpdump -i vnet0‘ shows:

15:47:39.041395 IP > Flags (S), seq 160880283, win 64240, options (mss 1460,nop,wscale 8,nop,nop,sackOK), length 0
15:47:39.041526 IP fedora.bear > ICMP fedora.bear tcp port microsoft-ds unreachable, length 60

And ‘net view’ eventually reports ‘System error 53: network path not found‘.
I also checked ‘iptables -L -v‘ (too verbose to paste here), no one got ‘REJECT’ed.

In case of ‘ftp’, it is similar to ‘samba’.

15:54:13.232366 IP > fedora.bear.ftp: Flags (S), seq 669575524, win 8192, options (mss 1460,nop,wscale 0,nop,nop,sackOK), length 0
15:54:13.232468 IP fedora.bear > ICMP fedora.bear tcp port ftp unreachable, length 60

It seems that host can not send package back to guest.

Am I missing something? What could be the cause?

linux – rdesktop from Fedora 31 to Windows 10

Today I installed Fedora 31 on my new SSD. I don’t recall ever being able to RDP into Windows 10 from Linux. I gave up on trying on my old Fedora 20 installation.

But now that I have the latest version of Fedora I should be getting the latest RDP apps which hopefully are Windows 10 Compatible.

Using KRDC, Vinage don’t work. I thought I would try running the rdesktop command and see if that works.

At first it appears OK, I get a prompt to accept/deny the host certificate, but then I get errors:

Autoselecting keyboard map 'en-us' from locale
Core(warning): Certificate received from server is NOT trusted by this system, an exception has been added by the user to trust this specific certificate.
Failed to initialize NLA, do you have correct Kerberos TGT initialized ?
Failed to connect, CredSSP required by server (check if server has disabled old TLS versions, if yes use -V option).

Running with the -V option gives a bunch of output on usage so I think it’s not accepting the switch.

linux – Eclipse is randomly delaying the entire Fedora 30 system

I have problems with my Eclipse 2020-03 (with the previous version it was the same), which I am running on fedora 30. At some random points, it seems that the whole system is overloaded. It turns out that the PC is working properly, I can perform all the actions, but they take 30 seconds each, and I want to see the result of saving by pressing Ctrl + s or switching between two windows (even while changing it (happens in slow motion). I know it's saved, and I even assume it's saved right away. It almost seems like there is a problem with just the graphics.
The problem occurs only while using eclipse, and not always (although 95% of the time after using eclipse for 2-15min). The closing eclipse doesn't solve it! It persists until restart. There are also times when everything starts working properly for a few seconds, but then it always comes back to delay. Today, for the first time, the system froze completely and I had to restart it by pressing a button instead of the console.

I increased the values ​​in eclipse.ini from -Xms and -Xmx and that helped a bit. Increased the time before the delay occurs.

I didn't find anything useful except that. It is very annoying and I can't encode anything while I'm on Linux because of that please help me. If I can provide additional information, please let me know.

linux – How to debug problems with Wayland in Fedora 32

I recently did a massive cleanup of my Fedora 32 system which included a lot of packages that were removed from the system, by the way, it removed the desktop environment I was using. Before, I was using Deepin DE (Deepin OS desktop environment, compatible with Fedora), but decided to go back to Fedora's default Gnome. The only problem I am experiencing now is that Gnome uses X11 instead of Wayland, which it has to use by default. I have a suspicion that while cleaning my system I might have accidentally removed some kind of package required for Gnome to work with Wayland. I tried to Google information on how to manage Wayland. Based on the information I found, I tried:

  1. Set /etc/gdm/custom.conf var & # 39; WaylandEnable & # 39; in true
  1. Set /etc/gdm/custom.conf var WaylandEnable to false and comment it out

BTW, in GDM session list, I don't have Gnome in Xorg variant. I only have Gnome and Gnome Classic variants.
I'm not very good at understanding how to professionally manage graphics subsystems like Xorg or Wayland on Linux, so I don't know where to look.

Please help me figure out what I'm missing to get the gnome to use wayland or where to see if the gnome rolls back from Wayland to X11 (if so).

Thank you

networking: Fedora in VMWare requires sudo dhclient on restart

I am running fedora 31 inside a vmware box on a Windows 10 host as my development machine (I am a software developer). Every time I reboot, my box doesn't have internet access and I have to run $ sudo dhclient. Any ideas on how to fix this? I don't even know where to start.

I run the box in NAT, but none of the network options makes the difference (for example, bridged, host only, etc.).

Apparently, it also started happening randomly. One day, there is simply no internet.

Thank you!

linux – Problems installing Fedora 31

I am facing strange problems while installing Fedora 31 on a PC.

Something went wrong

After a few seconds, the installation options appear (the mouse pointer is invisible but as I move, the mouse options are highlighted)

Try fedora window

If I select & # 39; try fedora & # 39 ;, the screen gets stuck in the window & # 39; something went wrong & # 39 ;.
If & # 39; install fedora & # 39; is selected, I can continue with the installation
installer window 1
installer window 2

journalctl output

journalctl -b _COMM = gdm-x-session output

lspci output

I've tried installing all the Fedora twists and they all work fine.
I also tried to install the workstation package in a Fedora twist, but the same problem when switching to the workstation (something with wrong error)
KDE spin output workstation installation

Using safe graphics mode solves the problem but then problems like half of the window visible at once, large text size, etc. they don't allow it to work easily.
So how can i solve this and thanks for the help in advance!

fedora: systemctl cannot start a service due to lack of permission to write the log file

I am trying to start a service using systemctl on a Fedora 31 machine, but it fails due to lack of permission to write the log file:

$ sudo systemctl start wildfly.service

Job for wildfly.service failed because the control process exited with error code.
See "systemctl status wildfly.service" and "journalctl -xe" for details.
$ journalctl -xe

drwxr-xr-x. 27 root    root    4096 Mar 21 17:50 ..

When editing the /etc/rc.d/init.d/wildfly file to write to / tmp it works, I just can't understand why it works on the expected path (/ var / log / wildfly).
Any ideas?

boot – Fedora UEFI and BIOS

I'm a bit confused with that BIOS / UEFI thing in Fedora.
I have dual boot Windows 10 (on my SSD) and a newly installed Fedora 31 workstation (on my HDD).
When I check that BIOS mode in Windows shows & # 39; Legacy & # 39 ;, also my motherboard specification (MSI Z370-A PRO) shows it has BIOS. Also, the BIOS menu title says & # 39; MSI Click BIOS 5 & # 39 ;.
But when I had been installing Fedora and created a /boot partition I got a warning that I need to have /boot/efi divide. So in addition to /boot, I believe /boot/efi the same size (250 MiB).
After PC installation and restart, it turned out that Fedora had automatically changed a boot order and set UEFI Hard Drive Fedora first
Now when I am using Windows there is a new local disk (F 🙂 (249 MB) containing EFI Y System directories and match_kernel archive.
Apparently my BIOS can handle UEFI devices like UEFI Hard Drive, UEFI CD / DVD, UEFI Flashdrive etc.
Also, my SSD containing Windows 10 is not marked as a UEFI device.

Did I do something wrong? Do I have UEFI or BIOS? And which partition of a free space of my HDD for Fedora is correct: /boot, /boot/efi Or both?
