Issues to display SNMP information

This is a typical error on snmpwalk at the beginning of the display information:

snmpwalk -v1 -c public 127.0.0.1 system
Expected "::=" (RFC5644): At line 493 in /usr/share/mibs/iana/IANA-IPPM-METRICS-REGISTRY-MIB
Expected "{" (EOF): At line 651 in /usr/share/mibs/iana/IANA-IPPM-METRICS-REGISTRY-MIB
Bad object identifier: At line 651 in /usr/share/mibs/iana/IANA-IPPM-METRICS-REGISTRY-MIB
Bad parse of OBJECT-IDENTITY: At line 651 in /usr/share/mibs/iana/IANA-IPPM-METRICS-REGISTRY-MIB
Bad operator (INTEGER): At line 73 in /usr/share/mibs/ietf/SNMPv2-PDU
Unlinked OID in IPATM-IPMC-MIB: marsMIB ::= { mib-2 57 }
Undefined identifier: mib-2 near line 18 of /usr/share/mibs/ietf/IPATM-IPMC-MIB

 Open /etc/snmp/snmp.conf and it should be as follows:

 mibs :
mibs +SNMPv2-MIB

 But, if you run ...

 snmptranslate -m all -Tz -On | sed -e 's/"//g' > /tmp/oids.txt

 ... to create your oids.txt, you still see the same error.
To fix them, you can edit the file /usr/share/mibs/iana/IANA-IPPM-METRICS-REGISTRY-MIB with vim and put the following sentences:

:%s/ := / ::= /g
:%s/Reference "RFC/Reference RFC/g
:wq

 Other option it's directly download the correct files and replace them:

 sudo wget http://www.iana.org/assignments/ianaippmmetricsregistry-mib/ianaippmmetricsregistry-mib -O /usr/share/mibs/iana/IANA-IPPM-METRICS-REGISTRY-MIB
sudo wget http://pastebin.com/raw/p3QyuXzZ -O /usr/share/mibs/ietf/SNMPv2-PDU

sudo wget http://pastebin.com/raw/gG7j8nyk -O /usr/share/mibs/ietf/IPATM-IPMC-MIB

 Now, you are done
Enjoy it!

Exception: Could not find a default OpenFlow controller in Mininet

If you try to run a mininet script like this  , maybe you will get this problem if you are under Ubuntu. Exception: Could not find a default OpenFlow controller  This is trigger because your system don't find a default controller . To enable it just add the first line and add the controller argument to net variable like the second line: from mininet.node import OVSController net = Mininet(topo=topo,host=CPULimitedHost, link=TCLink,controller = OVSController) Now, you will get the following error: c0 Cannot find required executable ovs-controller. Please make sure that it is installed and available in your $PATH: (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin) ovs-controller is a legacy name.

How to fix Android when developer options are not available for this user

Image
I have an Android One with Oreo version and suddenly my Android rebooted and after that it started to behave strangely: 1) Notification section doesn't work. I can't see notifications from my apps and the arrow and the screw icon to settings access don't work. 2) As I can't access to the notification area, I can't enable Use USB to Transfer Files to access to my phone memory. 3) I can't access to developer mode (I before active it with a lot of taps over Build number). Clicking on developer options just shows developer options are not available to this user. 4) I can't update or install the apps on google play. They freeze on Download pending... message 5) Home and Switch buttons don't work. They light up and vibrate when I tap them but they do nothing. This issue is apparently related to a deconfiguration of user accounts. To fix it, you need re-setup the users. As you can't access to the user manager (you are in guest mode
