duplicated connection working in an office

[chrisknapp98]

hi, me and my colleagues are experiencing duplicated connections from atlantis to Proxyman when we are working at the office. Thus, we receive the same network request multiple times with the exact same time, duration etc.

I couldn't find the root of the issue, but filtering in NetServiceTransport#connectToService(_ service: NetService) also gets the job done. Maybe it could be a change to be considered for a future release. Let's see if I manage to create a PR

A problem could be that with that change devices which have the same name couldn't connect both over the network to atlantis

Do you specify the Computer Name when starting the Atlantis Service?

By doing it, Atlantis only connects to this computer, not your colleague's computers.

You can find a name in the Atlantis Windows.

[NghiaTranUIT]

and what Atlantis library version you're using 🤔 ?

[chrisknapp98]

version 1.19.0

The issue is not that it connects to my colleagues computers. No matter if I specify the device in start call, atlantis still keeps connecting multiple times to my Proxyman client. Sometimes it doesn't but often the conection is there like 5 times

Okay I haven't got any permissions to push a new branch. But my fix is in line 226 after the guard let hostName to add

        guard !connections.contains(where: { connection in
            if case let NWEndpoint.service(name: connectedHostName, type: _, domain: _, interface: _) = connection.endpoint {
                let splittedHostName = hostName.split(separator: ".")
                let deviceName = splittedHostName.indices.contains(0) ? splittedHostName[0].lowercased() : "DEVICE_NAME"
                if connectedHostName.contains(deviceName) {
                    print("[Atlantis] Found duplicated endpoint")
                }
                return connectedHostName.contains(deviceName)
            }
            return false
        }) else {
            print("[Atlantis] Aborting new connection")
            return
        }

ohh I'm just noticing that splitting at a dot and taking index 0 only works with our devices because the host name of our devices always is the serial number with the .local suffix

If you don't mind, please add a checkpoint to this line

atlantis/Sources/Transporter.swift

Line 229 in a761f2c

print("[Atlantis] ✅ Connect to \(hostName)")

and see how many print output.

If it connect to the same Macbook multiple times, we can see multiple outputs.

[chrisknapp98]

exactly! That's how I knew atlantis connected to the same device multiple times. Without the guard block I added, this print with the exact same hostName can be seen multiple times.
I think this also especially happens when there are like 3+ colleagues in the office which are running Proxyman on their mac

[NghiaTranUIT]

@chrisknapp98 can you try this branch #120?

I refactor a little bit and prevent connecting multiple times to a single Host. I suppose that it can fix the bug.

seems to be working 👍
I censored the names because it would be the serial numbers

Thanks. Please play around with this update. If it's still working fine, I will release the fix this week 👍

[NghiaTranUIT]

Just a friendly reminder that I've bumped new version 1.20.0, which contains the fix.

However, if you've encountered this bug #121 , Let's try the Proxyman beta build 👍
