I'm trying to get data on the host with net-snmp (5.6.1.1)
snmpwalk -v2c -c public 192.168.0.102 1.3.6.1.2.1.25
HOST-RESOURCES-MIB::host = No Such Object available on this agent at this OID
Here's what it returns, the agent is configured on public to read-write and read-only.
The queried device (192.168.0.102) most likely doesn't implement the HOST-RESOURCES-MIB, which is located beneath the 1.3.6.1.2.1.25 branch.
If you've just installed/enabled NET-SNMP, keep in mind that the default snmpd.conf configuration file is fairly restrictive regarding queries from different hosts. You will need to update the configuration file to publish data from this branch.
It means the agent doesn't support any SNMP information underneath or at
the oid you requested. Or it does, but you don't have access to it. (try it with 'private' community)

So i am trying to make a catalog of OIDs for a device, I downloaded the manufacturer's MIB for the device and placed it into the file path where SNMP mibs are stored on linux. but when i run an SNMP walk on the specific device using its ip and specify a directory for Mib location it gives me an error. For example, snmpwalk -v1 -c public -M /usr/share/snmp/mibs 10.10.10.50 (device specific ip) gives me a result of the following with no specification on the device specific oids. Does anyone have any idea why that might be the case?

I'm creating a kickstart file for RHEL 8 and am trying to simplify network connectivity among machines. All of the machines will have onboard ethernet ports that will distribute eno1 and eno2 names, but also a separate card which will generate unique names when RHEL is installed.
My question is, can I use the kickstart to identify copper or fiber connections and give them names there or will I need to do this in the post-install section?
Can I use the kickstart to identify copper or fiber connections and give them names there or will I need to do this in the post-install section? From the Kickstart commands for network configuration you can set from the kickstart
B.4.1. network (optional)
Use the optional network Kickstart command to configure network information for the target system and activate the network devices in the installation environment. The device specified in the first network command is activated automatically. You can also explicitly require a device to be activated using the --activate option
--device= - specifies the device to be configured (and eventually activated in Anaconda) with the network command.
If the --device= option is missing on the first use of the network command, the value of the ksdevice= Anaconda boot option is used, if available. Note that this is considered deprecated behavior; in most cases, you should always specify a --device= for every network command.
The behavior of any subsequent network command in the same Kickstart file is unspecified if its --device= option is missing. Make sure you specify this option for any network command beyond the first.
You can specify a device to be activated in any of the following ways:
the device name of the interface, for example, em1
the MAC address of the interface, for example, 01:23:45:67:89:ab
the keyword link, which specifies the first interface with its link in the up state
the keyword bootif, which uses the MAC address that pxelinux set in the BOOTIF variable. Set IPAPPEND 2 in your pxelinux.cfg file to have pxelinux set the BOOTIF variable.
For example:
network --bootproto=dhcp --device=em1

I am creating a cluster in MicroK8s, however when using Kubernetes I am able to specify an API Server Advertise Address that I can use to join my cluster. I need that functionality in MicroK8s, however I haven't found a way that works.
Thus far I have modified the file at /var/snap/microk8s/current/certs/csr.conf with a new ip IP.5 MYIPV6 whilst also modifying the output of microk8s.kubectl config view --rawand using it in as the KubeConfig. Nothing has worked.
In general terms, I want to expose a public IPV6 Address so worker nodes can join my cluster.
I have a successful single-node install of ICP 3.1.0 CE. I want to access the console using a fully qualified DNS name instead of an IP address, and have a public wildcard certificate which I wish to use to secure console access.
I was able to add the myhostname-only and myhostname.mydomain.com variants to the console and change the console to use my public certificate, so that is all working properly. But when I log into the console using myhostname.mydomain.com and look at the URLs associated with the interface items, some refer (correctly) to paths anchored at myhostname.mydomain.com... and some (e.g. Catalog, some items under Platform, etc) refer to paths anchored off the IP address.
Is there a way to change this behavior, such that FQDNs are used consistently throughout, without reinstalling ICP?
If not, and if the mixed results I see are because I did something boneheaded during install, can someone clarify what I should do to ensure that all paths post-installation are FQDNs instead of IP addresses?
Thanks!
I was unable to find a way to correct the discrepancies in URLs, so I followed Justin's lead... I deleted the cluster, explicitly set cluster_lb_address to the desired FQDN in config.yaml, and reinstalled. Now all URLs are FQDNs.
I don't know if this is the recommended way to fix this issue, or if it is a bug, or if I was simply missing something... but setting cluster_lb_address achieved the desired result.
I've got XAMPP setup on my laptop (OSX 10.6) for dev, and I wanted to use VirtualDocumentRoot so that I could do *.localhost and it would automap to the folder under my sites directory. I've got this all set up fine, and it works great, but when I got to work today, I found an issue with the way our LAN handles DNS.
Long story short, instead of checking the LAN DNS server for local domains, it goes out to the root. Is there a way to get bind to check the DHCP supplied DNS server for addresses it's not responsible for? Or alternatively, is there a way to get my os to use the DHCP DNS server first, and then fall back to the local with minimal performance hit?
Thanks!
I'm using Linux Arch, but as MacOSX is based on some *nix system - may this ideas helps you:
Take a look at the file /etc/resolv.conf. In my setup this file is automatically generated by NetworkManager.
This document writes about ways to update /etc/resolv.conf when dhcpcd, NetworkManager or dhclient is used: https://wiki.archlinux.org/index.php/Dnsmasq#DHCP_Setup
In this way you do just prepend the local dns before the dhcp's dns (or static if you're switching to a static configuration). Make sure you remove all forwarders from your dns-server.
If macos does not use them, may this workaround gives you a hint, even if it's very limited:
Add a global name-server (like google's one 8.8.8.8) to your dns-server's list of forwarders.
