Hi, Following the instructions I set up my own Interactsh server, however after starting it, I can't connect to it with the interactsh client.

Server running :

Attempt to connect with the client :

And I think my DNS configuration is good because if I run a custom DNS that I wrote in Ruby, it responds well to queries

Regards

Version: 0.0.7 Go version: 1.17.5 linux/amd64 Hello guys, the issue I'm having is trying to connect the client to my server. I execute the command: interactsh-client -server https://example.com

The server returns:

[FTL] Could not create client: could not make register request: POST https://example.com/register giving up after 6 attempts: Post "https://example.com/register": dial tcp server_ip
:443: connect: connection refused

I also tried http://example.com with the same response. And I also tried the web client with custom server pointing to example.com with no success.

My server is running on an Oracle VM. My domain in registered on Namecheap. I configured it with custom nameservers (ns1 and ns2 both pointing to server_ip, which is the VM's IP). I am running BIND9 on it to act as nameserver. If I enable nginx on my VM I can access it using http://example.com. If I run nslookup ubuntu.com example.com from my Windows PC I get the correct response. I start my server with this command: interactsh-server -domain example.com

The response I get leads me to believe it is running correctly:

I tried shutting down my firewall to see if it was interfering in some way with the command sudo iptables -F. I also made sure ports 53, 80 and 443 were open for TCP packets on the VM configuration.

Even so, I am getting connection refused.

Hi team,

I have created a DO Debain Droplet and installed a Floating IP added the configuration as said under the self hosted instance guide. Can anyone please help?

When I run the command interactsh-server -domain mydomain.com -hostmaster [email protected] -ip [VPS IP]. The following output is given without any errors:

But the server is not giving A records when queried. I already had a letsencrypt cert but even after I deleted the cert nothing changed the same output is given

We are trying to setup interactsh-server. But we are hitting this below error. We have already tried to setup this on ubuntu. Since Debian is recommended, we were trying there. But there also we are hitting the same issue.

This commit fixes three issues:

• Previously if a "listen IP" wasn't specified the public IP looked up from a "what is my IP" API was used. In many cases cloud VMs do not have their "public" IP bound to an interface (such as Amazon EC2), causing startup to fail:

  $ ./interactsh-server -domain example.com
  [FTL] Could not listen for udp DNS on 203.0.113.42:53 (listen udp 203.0.113.42:53: bind: cannot assign requested address)
  

  This has been changed to bind to an appropriate wildcard address, which should work in almost all cases.

• The default wildcard listen address has been changed to :<port number>, which will cause the socket to pick a suitable wildcard address depending on whether the machine is dual stack or IPv4-only. This further supports upcoming work to add IPv6 support.

• IPv6 literals may now be passed to "-listen-ip" without needing to wrap them in [].

Hi, I'm using Nuclei, interact and notify to spot OOB requests, however the webhook is spamming me with this

Could a IP filter argument be added so they're not passed through into STDOUT?

Maybe it is not very necessary, but if it would be something interesting, a client for burpsuite (community), it is necessary to take into account that it would be an extra maintenance, no wonder they reject the idea. but still I comment

Hello and thank you for this awesome tool, it will surely come in handy during our testing.

The current behavior of interactsh is to create a randomized subdomain like c282n3l3djgbti5v595gcnenzdoyyyyyn.domain.tld, which is fine and all, however, we have a pretty nice 4 x 2 domain and we feel that smaller payloads are the best, so could you allow the use of the base domain and/or customized sub-domains for self-hosted servers in addition to the randomized subdomains?

Edited to ask for customized sub-domains option as well. 👍🏻

Bumps goreleaser/goreleaser-action from 3 to 4.

Dependabot will resolve any conflicts with this PR as long as you don't alter it yourself. You can also trigger a rebase manually by commenting @dependabot rebase.

Please describe your feature request:

README.md for interactsh-server says:

-e, -eviction int       number of days to persist interaction data in memory (default 30)

There should be a way to specify an infinite eviction (i.e. disable the purging of sessions and interaction data)

Describe the use case of this feature:

Someone with a self-hosted interactsh-server may want to do very long-running polling of a session. For example:

• Day 0 - create an interactsh session and do a very long poll against it using interactsh-client, e.g. piped to notify
• Day 1 - use the session to generate canary hostnames. Use those hostnames e.g. in a blind time-delayed SSRF or blind XSS scenario
• Day 100 - have the hostname be accessed by a victim, receive notification of this event

With the default eviction of 30 days, my understanding is that the long-running interactsh-client started on day 0 will silently stop receiving events after 30 days. The interactsh-client will stay connected and will keep polling, will not get any errors, but will not receive events.

Alternative solution:

A user of interactsh-server can do -e 999999 to get an essentially infinite eviction time :) but this is not very clean

Risks

There might be an accidental or malicious DoS risk to an interactsh-server that is configured to never evict sessions

SMTP server does not record interaction if email contains @ symbol in local part of email, e.g., "foo@bar"@example.com.

Interactsh version: 1.0.7

Current Behavior:

After sending email to "a@b"@ce3pf0s9952p8p7a93ggm3pm3um4hxpe3.oast.pro

{"protocol":"dns","unique-id":"ce3pf0s9952p8p7a93ggm3pm3um4hxpe3",
"full-id":"ce3pf0s9952p8p7a93ggm3pm3um4hxpe3","q-type":"MX",...}

Expected Behavior:

Expect to also receive SMTP interaction.

Steps To Reproduce:

Example: steps to reproduce the behavior:

1. Run 'interactsh ...'
2. Send email to "a@b"@[interactsh-domain]
3. Observe DNS interaction but no SMTP interaction

Interactsh version:

main / dev
