sqsh
MS SQL client from Linux, an alternative when mssqlclient fails.
Interactive MS SQL Server client for Linux, built on FreeTDS. It plays the same role as impacket's `mssqlclient.py` and sometimes works where that one fails (older server versions, local instead of domain authentication). Its own quirk is that statements do not run until you type `go` on its own line, which surprises you the first time. From there you reach `xp_cmdshell` just the same to run commands as the service account.
