19 .Sh NAME
20 .Nm gotsh
21 .Nd Game of Trees Shell
22 .Sh SYNOPSIS
23 .Nm Fl c Sq Cm git-receive-pack Ar repository-path
24 .Nm Fl c Sq Cm git-upload-pack Ar repository-path
25 .Sh DESCRIPTION
26 .Nm
27 is the network-facing interface to
28 .Xr gotd 8 .
29 It implements the server-side part of the Git network protocol used by
30 .Xr git 1
31 and
32 .Xr got 1 .
33 .Pp
34 .Nm
35 is not an interactive shell.
36 .Nm
37 is intended to be configured as the login shell of Git repository
38 user accounts on servers running
39 .Xr gotd 8 .
40 If users require a different login shell,
41 .Nm
42 can be installed in the command search path under the names
43 .Cm git-receive-pack
44 and
45 .Cm git-upload-pack .
46 .Pp
47 The users can then interact with
48 .Xr gotd 8
49 over the network.
50 When users invoke commands such as
51 .Cm got send
52 and
53 .Cm got fetch
54 on client machines,
55 .Xr got 1
56 will connect to the server with
57 .Xr ssh 1 .
58 .Nm
59 will facilitate communication between
60 .Xr gotd 8
61 running on the server machine and the
62 .Xr got 1
63 or
64 .Xr git 1
65 program running on the client machine.
66 .Pp
67 Users running
68 .Nm
69 should not have access to Git repositories by means other than
70 accessing the unix socket of
71 .Xr gotd 8
72 via
73 .Nm .
74 .Pp
75 It is recommended to restrict
76 .Xr ssh 1
77 features available to users of
78 .Nm .
79 See the
80 .Sx EXAMPLES
81 section for details.
82 .Sh ENVIRONMENT
83 .Bl -tag -width GOTD_UNIX_SOCKET
84 .It Ev GOTD_UNIX_SOCKET
85 Set the path to the unix socket which
86 .Xr gotd 8
87 is listening on.
88 If not specified, the default path
89 .Pa /var/run/gotd.sock
90 will be used.
91 .El
92 .Sh EXAMPLES
93 .Xr sshd_config 5
94 directives such as the following are recommended to protect the server
95 machine and any systems reachable from it, especially if anonymous users
96 are allowed to connect:
97 .Bd -literal -offset indent
98 Match User anonymous
99     DisableForwarding yes
100     PermitTTY no
101 .Ed
102 .Pp
103 It can be convenient to add all relevant users to a common group, such as
104 .Dq developers ,
105 and then use this group as the Match criteria:
106 .Bd -literal -offset indent
107 Match Group developers
108     DisableForwarding yes
109     PermitTTY no
