Overview ¶
Package procspy lists TCP connections, and optionally tries to find the owning processes. Works on Linux (via /proc) and Darwin (via `lsof -i` and `netstat`). You'll need root to use Processes().

Functions ¶
func ReadDirNames ¶
func ReadNetnsFromPID ¶
ReadNetnsFromPID gets the netns inode of the specified pid
Types ¶
type CachingWalker ¶
type CachingWalker struct {
// contains filtered or unexported fields
}
CachingWalker is a walker than caches a copy of the output from another Walker, and then allows other concurrent readers to Walk that copy.
func NewCachingWalker ¶
func NewCachingWalker(source Walker) *CachingWalker
NewCachingWalker returns a new CachingWalker
func (*CachingWalker) Name ¶
func (*CachingWalker) Name() string
Name of this ticker, for metrics gathering
func (*CachingWalker) Tick ¶
func (c *CachingWalker) Tick() error
Tick updates cached copy of process list
type ConnIter ¶
type ConnIter interface {
Next() *Connection
}
ConnIter is returned by Connections().
type Connection ¶
type Connection struct {
LocalAddress net.IP
LocalPort uint16
RemoteAddress net.IP
RemotePort uint16
Inode uint64
Proc Proc
Listening bool
}
Connection is a (TCP) connection. The Proc struct might not be filled in.
type ConnectionScanner ¶
type ConnectionScanner interface {
// Connections returns all established (TCP) connections.
Connections() (ConnIter, error)
// Stops the scanning
Stop()
}
ConnectionScanner scans the system for established (TCP) connections
func NewConnectionScanner ¶
func NewConnectionScanner(walker Walker, procRoot string, processes bool) ConnectionScanner
NewConnectionScanner creates a new Linux ConnectionScanner
func NewSyncConnectionScanner ¶
func NewSyncConnectionScanner(walker Walker, procRoot string, processes bool) ConnectionScanner
NewSyncConnectionScanner creates a new synchronous Linux ConnectionScanner
type ProcNet ¶
type ProcNet struct {
// contains filtered or unexported fields
}
ProcNet is an iterator to parse /proc/net/tcp{,6} files.
func (*ProcNet) Next ¶
func (p *ProcNet) Next() *Connection
Next returns the next connection. All buffers are re-used, so if you want to keep the IPs you have to copy them.
