Telegram is still leaking user IP addresses to contacts

Jump

  • I agree. This requires the user to actually save the attacker phone number as contact in order for this the IP address to “leak”

    There’s still a chance that your contacts would have been hacked, and one could be vulnerable. But it all comes back to your risk profile. If you require hiding your IP address, you should turn this off or even use a VPN for all your traffic.

    • How much swap?

    Jump

  • As most have pointed, the “always 2x” rule doesn’t have that much of relevance in 2023 as most computers now has more than 4GB of RAM. I would only use that much of a swap when using a low hardware.

    For desktop, I would never go swapless, though. In the event of memory pressure, swap would still help in that situation so that OOM Killer do not kick off and unintentionally kill my working process. Plus it helps that Linux can move the least used data to the swap and use the RAM for filesystem cache.

    So my rule of thumb, for desktop: If RAM < 8GB: Swap == 2x RAM If RAM => 8GB: Swap == 1x RAM

    For servers, I think it depends on the workload. I keep a small amount, like probably 50% of RAM or less. But for stuff like Redis, it doesn’t make sense to have swap. You want to ensure that everything is in the memory.
