To use cloudflared as a socks proxy, add an ingress on the server
side with your desired rules. Rules are matched in the order they
are added. If there are no rules, it is an implicit allow. If
there are rules, but no rule matches match, the connection is denied.
ingress:
- hostname: socks.example.com
service: socks-proxy
originRequest:
ipRules:
- prefix: 1.1.1.1/24
ports: [80, 443]
allow: true
- prefix: 0.0.0.0/0
allow: false
On the client, run using tcp mode:
cloudflared access tcp --hostname socks.example.com --url 127.0.0.1:8080
Set your socks proxy as 127.0.0.1:8080 and you will now be proxying
all connections to the remote machine.
* Allow partial reads from a GorillaConn; add SetDeadline (from net.Conn)
The current implementation of GorillaConn will drop data if the
websocket frame isn't read 100%. For example, if a websocket frame is
size=3, and Read() is called with a []byte of len=1, the 2 other bytes
in the frame are lost forever.
This is currently masked by the fact that this is used primarily in
io.Copy to another socket (in ingress.Stream) - as long as the read buffer
used by io.Copy is big enough (it is 32*1024, so in theory we could see
this today?) then data is copied over to the other socket.
The client then can do partial reads just fine as the kernel will take
care of the buffer from here on out.
I hit this by trying to create my own tunnel and avoiding
ingress.Stream, but this could be a real bug today I think if a
websocket frame bigger than 32*1024 was received, although it is also
possible that we are lucky and the upstream size which I haven't checked
uses a smaller buffer than that always.
The test I added hangs before my change, succeeds after.
Also add SetDeadline so that GorillaConn fully implements net.Conn
* Comment formatting; fast path
* Avoid intermediate buffer for first len(p) bytes; import order
- Move packages the provide generic functionality (such as config) from `cmd` subtree to top level.
- Remove all dependencies on `cmd` subtree from top level packages.
- Consolidate all code dealing with token generation and transfer to a single cohesive package.
* Issue-285: Detect TARGET_ARCH correctly for FreeBSD amd64 (uname -m returns amd64 not x86_64)
See: https://github.com/cloudflare/cloudflared/issues/285
* Add note not to `go get github.com/BurntSushi/go-sumtype` in build directory as this will cause vendor issues
