Using any IP, ETA is always 0 seconds and states there are 0 services to fingerprint.

On kali, works fine. On manjaro is where the issue is seen

[assetgrower]

same here.

Do you guys have masscan installed?

[axelarator]

Yup. Nmap and masscan were installed from AUR

[assetgrower]

Yes, in /usr/bin/masscan

I had the issue and I realized it was because I wasn't using sudo.

If I use masscan directly without using sudo I get back:

FAIL: wlp3s0: You don't have permission to capture on that device (socket: Operation not permitted)
 [hint] need to sudo or run as root or something
 [hint] I've got some local priv escalation 0days that might work
adapter[wlp3s0].init: failed

With Silver the error message was being sent to /dev/null so I got success message but ended up with only {} in my output folder.

Can anyone with the problem see if using sudo fixes the issue?

@kirkins That's a good lead!

Add the following code to line #73 in silver.py and run it again.

print('masscan%s-p%s --rate 10000 -oG %s %s %s >/dev/null 2>&1' % (host, ports_to_scan, savefile, hostfile, exclude)

Copy the printed out masscan command and run it with sudo in your terminal and see if masscan works.

@s0md3v I'm sure it works because silver works perfectly fine for me once I use sudo. My result-targets.txt is as expected once I had the correct permissions.

[s0md3v]

Thanks @kirkins 🎉

I am pushing a patch!

[s0md3v]

The root permission thing has been documented and internal checks for dependencies (nmap, masscan, psutil) and the permission itself with pushed soon.

suggested line

For everyone who will come here to trouleshoot, this line is missing closing bracket and should be:

print('masscan%s-p%s --rate 10000 -oG %s %s %s >/dev/null 2>&1' % (host, ports_to_scan, savefile, hostfile, exclude))
