  • In the supply and logistics sectors, email communication is pivotal. However, organizations face threats like email fraud and phishing. GOLINE SA's clients struggled with configuring email authentication protocols manually. To address this challenge, GOLINE SA became an MSP Partner of PowerDMARC, collaborating to streamline implementation and management. PowerDMARC's cloud-based platform automated DMARC, SPF, and DKIM protocols for GOLINE SA's clients. This streamlined the transition to DMARC enforcement policies, bolstering domain protection without compromising email deliverability. The intuitive platform facilitated easy navigation and provided detailed reporting for proactive issue resolution. GOLINE SA's clients experienced tangible benefits: Enhanced Email Security: Automated protocols...
  • Route RPKI validation April 1st, 2022
    RPKI is a security framework by which network owners can validate and secure the critical route updates or Border Gateway Protocol (BGP) announcements between public Internet networks. BGP is essentially the central nervous system of the Internet and one of its fundamental building blocks. The main function of BGP is to facilitate efficient routing between Autonomous Systems (AS), by building and maintaining the Internet routing table. The Internet routing table is effectively the navigation system of the Internet and without it, traffic would be unable to flow between its constituent networks. Unfortunately, routing equipment alone cannot distinguish between legitimate and malicious routing announcements,...
  • RIPE – Atlas Anchor February 17th, 2022
    We have become an even more integral part of the RIPE Atlas project by hosting an anchor, a device that allows for latency analysis of traffic between autonomous systems. Atlas anchors play an integral role in the RIPE Atlas network by acting both as enhanced RIPE Atlas probes with more measurement capacity, as well as regional measurement targets within the greater RIPE Atlas network. Anchors are able to perform many more measurements than a regular RIPE Atlas probe, and the large amount of data they collect is made available to everyone. In addition, anchors act as powerful targets that can...

Aggiornamnto manuale di Switch Catalyst in stack con file .bin

Step-by-Step Instructions
Step 1 – Download the .bin Image

Step 2 – Verify the Available Memory
You can verify the available memory in the Flash file system of both switches individually

Step 3 – Copy the Images to the Flash File System
Copy the .bin image from the TFTP server to the Flash file system of both switches.

Switch#copy tftp: flash1:
Address or name of remote host []?
Source filename [c3750-advipservicesk9-mz.122-25.SEE2]? c3750-advipservicesk9-
Destination filename [c3750-advipservicesk9-mz.122-25.SEE2.bin]?
Accessing tftp://…
Loading c3750-advipservicesk9-mz.122-25.SEE2.bin from (via Vlan1)
!— Output is truncated.
[OK – 8172194 bytes]
172194 bytes copied in 203.718 secs (40115 bytes/sec)

Switch#copy tftp: flash2:
Address or name of remote host []?
Source filename [c3750-advipservicesk9-mz.122-25.SEE2.bin]?
Destination filename [c3750-advipservicesk9-mz.122-25.SEE2.bin]?
Accessing tftp://…
Loading c3750-advipservicesk9-mz.122-25.SEE2.bin from (via Vlan1):
!— Output is truncated
[OK – 8172194 bytes]

8172194 bytes copied in 186.655 secs (43782 bytes/sec)

Step 4 – Configure the Boot Variable
Configure the boot variable to boot the switch with the newly copied IOS:

Switch(config)#boot system switch all flash:/
Switch#write memory

Step 5 – Verify Before the Reload
Verify the boot variable:

Switch#show boot
BOOT path-list : flash:/c3750-advipservicesk9-mz.122-25.SEE2.bin

RECOVERY – format flash and reload firmware

Cancellare tutto il contenuto della flash. Questa operazione ci mette circa 15 minuti.
format flash

Initialize the flash:
switch: flash_init

Initialize the management interface:
switch: mgmt_init

Then assign an IP address to the management interface:
switch: set IP_ADDR
switch: set DEFAULT_ROUTER

Then configure your TFTP server to have an IP on the same subnet and connect it to the management interface of the switch 

Now to tell the switch to retrieve the firmware image:
switch: copy tftp:// flash:c2960x-universalk9-mz.152-5b.E.bin
Se la copia non dovesse partire reinizializzare l'interfaccia mgmt 
switch: mgmt_init

Set boot image:
switch: boot flash:c2960x-universalk9-mz.152-5b.E.bin
