From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I'm having trouble getting an IP address via DHCP on my HP ProLiant DL380 Gen9 server running Debian. I've tried various troubleshooting steps, but nothing seems to work.

Error messages:

  • "No DHCPOFFERS received"
  • "No working leases in persistent database - sleeping"
  • "Activation of network connection failed" (GNOME)
  • "IP configuration unavailable" (Plasma)

Hardware:

  • HP ProLiant DL380 Gen9 server

Software:

  • Debian operating system
  • GNOME and Plasma desktop environments

Troubleshooting steps:

  • Checked network cable and ensured it's properly connected
  • Restarted network service
  • Set /etc/NetworkManager/NetworkManager.conf managed=true

Additional information:

  • Internet worked during the Debian installation process, but not after booting into the installed system.
  • The problem occurs on both GNOME and Plasma desktop environments, but Plasma provides a slightly more helpful error message.

I'd appreciate any help or guidance on resolving this issue. Has anyone else experienced similar problems with DHCP on a HP ProLiant DL380 Gen9 server with Debian?

62.49.7.152 is my public IP, if that's what you mean. How do I use that information, other than allowing others to know my approximate location?

I'm looking for the private IP. (The one your router has on the inside network)

How do I find that? Is it written on the router somewhere, or is there a command to run to find it?

How did you set it up? Did you just plug it in and forget about it?

[–] [email protected] 1 points 1 month ago (1 children)

I didn't set it up; another member of my household did

Oh

Is your phone connected to WiFi? What do the network settings show on your phone?

Did you want a specific part of network settings, or is this helpful?

Set your gateway to 192.168.1.1. Can you then ping 1.1.1.1?

Here are the network settings

I tried changing the IP in manual settings, I'm not sure how I ping an IP, I assume it's a command that I don't know, but as the screenshots show, accessing a website didn't work. I saw an IP in the startup menu and tried that but it didn't seem to work

Your netmask should be 255.255.255.0

[–] [email protected] 1 points 1 month ago (1 children)

Why is that? I applied the change, and restarted the Ethernet connection, but I still don't have internet

You have a upstream issue then. I would start by checking the physical port and then work your way up until you find the fault.

[–] [email protected] 1 points 1 month ago

Hmm. One way to check multiple options at once is to try the install again and see it internet is still present when installing the OS, as it was before. If it is, that would rule out a hardware issue.

I tried what I said, reinstalling to see if it still had internet. It did not. Therefore I went into a rabbithole of trying to rule out specific things of why it was working then but not now, and I still have no idea why it was working then, but I have plugged the Ethernet powerline into a new, more inconvenient, plug socket, and the wired internet is mostly working! I can still access most sites, but Firefox won't connect to addons.mozilla.com or accounts.firefox.com. Idk if that's a Firefox issues or a network issue, but it's mostly working now, which is great!
