NAME

SYNOPSIS

DESCRIPTION

13       in.uucpd is the server for supporting UUCP connections over networks.
14
15
16       in.uucpd is invoked by inetd(1M) when a UUCP connection is established,
17       that is, a connection to the port indicated in the "uucp" service spec‐
18       ification, and executes the following protocol. See services(4):
19
20           1.     The  server  prompts  with login:. The uucico(1M) process at
21                  the other end must supply a username.
22
23           2.     Unless the username refers to an account without a password,
24                  the  server  then prompts with Password:. The uucico process
25                  at the other end must supply the password for that account.
26
27
28       If the username is not valid, or is valid but refers to an account that
29       does  not have /usr/lib/uucp/uucico as its login shell, or if the pass‐
30       word is not the correct password for that account,  the  connection  is
31       dropped.   Otherwise,  uucico is run, with the user ID, group ID, group
32       set, and home directory for that account, with  the  environment  vari‐
33       ables  USER  and   LOGNAME set to the specified username, and with a -u
34       flag specifying the username. Unless the -n flag is specified,  entries
35       are  made  in  /var/adm/utmpx, /var/adm/wtmpx, and /var/adm/lastlog for
36       the username. in.uucpd must be invoked by a user with appropriate priv‐
37       ilege (usually root) in order to be able to verify that the password is
38       correct.

SECURITY

41       in.uucpd uses pam(3PAM) for  authentication,  account  management,  and
42       session  management.   The  PAM  configuration  policy,  listed through
43       /etc/pam.conf, specifies the modules to be used for in.uucpd. Here is a
44       partial  pam.conf file with entries for uucp using the UNIX authentica‐
45       tion, account management, and session management module.
46
47         uucp    auth requisite          pam_authtok_get.so.1
48         uucp    auth required           pam_dhkeys.so.1
49         uucp    auth required           pam_unix_auth.so.1
50
51         uucp    account requisite       pam_roles.so.1
52         uucp    account required        pam_projects.so.1
53         uucp    account required        pam_unix_account.so.1
54
55         uucp      session required      pam_unix_session.so.1
56
57
58
59       If there are no entries for the uucp service, then the entries for  the
60       "other"  service  will  be used. If multiple authentication modules are
61       listed, then the peer may be prompted for multiple passwords.

NOTES

109       The in.uucpd service is managed by  the  service  management  facility,
110       smf(5), under the service identifier:
111
112         svc:/network/uucp
113
114
115
116
117       Administrative actions on this service, such as enabling, disabling, or
118       requesting restart, can be performed using  svcadm(1M).  Responsibility
119       for  initiating  and restarting this service is delegated to inetd(1M).
120       Use inetadm(1M) to make configuration changes and to view configuration
121       information for this service. The service's status can be queried using
122       the svcs(1) command.
123
124
125       The pam_unix(5) module is no longer supported. Similar functionality is
126       provided   by   pam_authtok_check(5),   pam_authtok_get(5),   pam_auth‐
127       tok_store(5), pam_dhkeys(5),  pam_passwd_auth(5),  pam_unix_account(5),
128       pam_unix_auth(5), and pam_unix_session(5).
