Features

  • Connect to multiple remote machines concurrently
  • Persistent SSH connection
  • DSL query based on the labels
  • Manage number of sessions per SSH connection
  • Limit amount of stdout and stderr data in bytes
  • Higher-level API for building automation

Sample query with label

labels := map[string]string {
  "POP" : "LAX",
  "OS" : "JUNOS",
}
// sets labels to a client
vs.AddClient(addr, config, vssh.SetLabels(labels))
// query with label
vs.RunWithLabel(ctx, cmd, timeout, "(POP == LAX || POP == DCA) && OS == JUNOS")

Basic example

vs := vssh.New().Start()
config := vssh.GetConfigUserPass("vssh", "vssh")
for _, addr := range []string{"54.193.17.197:22", "192.168.2.19:22"} {
  vs.AddClient(addr, config, vssh.SetMaxSessions(4))
}
vs.Wait()

ctx, cancel := context.WithCancel(context.Background())
defer cancel()

cmd:= "ping -c 4 192.168.55.10"
timeout, _ := time.ParseDuration("6s")
respChan := vs.Run(ctx, cmd, timeout)

for resp := range respChan {
  if err := resp.Err(); err != nil {
    log.Println(err)
      continue
    }

  outTxt, errTxt, _ := resp.GetText(vs)
  fmt.Println(outTxt, errTxt, resp.ExitStatus())
}

Stream example

vs := vssh.New().Start()
config, _ := vssh.GetConfigPEM("vssh", "mypem.pem")
vs.AddClient("54.193.17.197:22", config, vssh.SetMaxSessions(4))
vs.Wait()

ctx, cancel := context.WithCancel(context.Background())
defer cancel()

cmd:= "ping -c 4 192.168.55.10"
timeout, _ := time.ParseDuration("6s")
respChan := vs.Run(ctx, cmd, timeout)

resp := <- respChan
if err := resp.Err(); err != nil {
  log.Fatal(err)
}

stream := resp.GetStream()
defer stream.Close()

for stream.ScanStdout() {
  txt := stream.TextStdout()
  fmt.Println(txt)
}
