Chaika•4/2/24, 2:58 PM

Pretty much. There is TCP Sockets: https://developers.cloudflare.com/workers/runtime-apis/tcp-sockets/, but port 25 is banned and even if you could use an alt port for submitting you'd need to modify or find (and I doubt any exist) a mail sending library to support the non-standard tcp socket api

Maybe someone will make one for Worker's TCP API one day; I imagine there's some service with a non-25 port out there. Thanks for confirming!

#Hono Cloudinary

How can i upload files to Cloudinary in the Hono app? Everything is sorted but i am not able to get the path of the file as the Cloudinarys uploader function asks for the file path.

This is the utils file of Cloudinary

import {v2 as cloudinary} from "Cloudinary"
import fs from "fs"

cloudinary.config({ 
  cloud_name: process.env.CLOUDINARY_CLOUD_NAME, 
  api_key: process.env.CLOUDINARY_API_KEY,

const uploadOnCloudinary = async (localFilePath) => {
    try {
        if (!localFilePath) return null
        //upload the file onCloudinaryy
        const response = await cloudinary.uploader.upload(localFilePath, {
            resource_type: "auto"
        })
        // file has been uploadedsuccessfull
        //console.log("file is uploaded onCloudinaryy ", response.url);
        fs.unlinkSync(localFilePath)
        return response;

    } catch (error) {
        fs.unlinkSync(localFilePath) // remove the locally saved temporary file as the upload operation got failed
        return null;
    }
}

export {uploadOnCloudinary}

// i get the file but not able to get the path

If you were using calls to different Durable Object Instances maybe. Service Bindings would just share the same isolate/thread though, and I would imagine calls out to the same script would just land back on the same isolate, since they just go to the same metal/machine

Just curious about this -> I have a worker and when I traceroute from Delhi NCR region(India) in vultr (just a test), i see that it basically terminates the traffic in Singapore. Is this expected?. I have seen questions in the past that asked similar questions (https://community.cloudflare.com/t/cloudflare-peerings-in-india/15755).

C

Chaika•4/2/24, 11:17 PM

Pretty normal yea, lots of people have reported Indian ISPs routing to Singapore. Routing isn't just about the closest place, Cloudflare controls which routes are available to who (which carrier, ix, etc) and ISP has the final control over where it is routed to. This isn't a Workers thing, but a general cdn thing

that's not surpising, geolocation with anycast ips like CF is always wrong

Santosh•4/3/24, 12:58 AM

How do I know the real location? SFO seems irreasonable with that latency

C

Chaika•4/3/24, 12:58 AM

That IP exists in more then one location (anycast) so it's hard to assign a single location to it

S

Santosh•4/3/24, 12:59 AM

Yes, Anycast it is!

SSantosh How do I know the real location? SFO seems irreasonable with that latency

Chaika•4/3/24, 1:00 AM

In general, you can go to

/cdn-cgi/trace

/cdn-cgi/trace

path of your website, ex:

https://d1-a-ut.makemyparty.live/cdn-cgi/trace

https://d1-a-ut.makemyparty.live/cdn-cgi/trace

https://d1-a-ut.makemyparty.live/cdn-cgi/trace

https://d1-a-ut.makemyparty.live/cdn-cgi/trace, and look at

colo={airportcode}

colo={airportcode}

colo={airportcode}

colo={airportcode}, and that airport code is the identifider of the location you hit

C

Chaika•4/3/24, 1:00 AM

Of course, you can't do that with most looking glasses, so you just have to guess by ping time or if traceroute or reverse dns exposes something obvious. Sometimes you'll see one of the end IPs be an Internet Exchange making it pretty obvious

S

Santosh•4/3/24, 1:01 AM

And I would have to do this from within India if I want to really locate that colo (in this particular case)

S

Santosh•4/3/24, 1:02 AM

Is there a cloudflare utility like thatof Vultr that allows me to trace it locally to a region?

C

Chaika•4/3/24, 1:02 AM

for example:

C

Chaika•4/3/24, 1:02 AM

if you google

38.10.0.47

38.10.0.47

38.10.0.47

38.10.0.47, you get a peering db result, it's CF's IP for them on Extreme IX in Bangalore, so it's most likely going to Cf's Banglore colo

S

Santosh•4/3/24, 1:02 AM

gotcha!

C

Chaika•4/3/24, 1:03 AM

should probably go to #off-topic or #general-help since this isn't workers related

Does anybody know if there's any way to send email via SMTP on Workers? I assume I'll need to use an
