rpc.rexd, rexd - RPC-based remote execution server SYNOPSIS
/usr/sbin/rpc.rexd [-s] DESCRIPTION
rpc.rexd is the Sun RPC server for remote program execution. This daemon is started by inetd(1M) whenever a remote execution request is made. For non-interactive programs, the standard file descriptors are connected directly to TCP connections. Interactive programs involve pseudo- terminals, in a fashion that is similar to the login sessions provided by rlogin(1). This daemon may use NFS to mount file systems speci- fied in the remote execution request. There is a 10240 byte limit for arguments to be encoded and passed from the sending to the receiving system. OPTIONS
The following option is supported: -s Secure. When specified, requests must have valid DES credentials. If the request does not have a DES credential it is rejected. The default publickey credential is rejected. Only newer on(1) commands send DES credentials. If access is denied with an authentication error, you may have to set your publickey with the chkey(1) command. Specifying the -s option without presenting secure credentials will result in an error message: Unix too weak auth (DesONly)! SECURITY
rpc.rexd uses pam(3PAM) for account and session management. The PAM configuration policy, listed through /etc/pam.conf, specifies the mod- ules to be used for rpc.rexd. Here is a partial pam.conf file with rpc.rexd entries for account and session management using the UNIX mod- ule. rpc.rexd account requisite rpc.rexd account required rpc.rexd account required rpc.rexd session required If there are no entries for the rpc.rexd service, the entries for the "other" service will be used. rpc.rexd uses the getpwuid() call to determine whether the given user is a legal user. FILES

Diagnostic messages are normally printed on the console, and returned to the requestor. NOTES
Root cannot execute commands using rexd client programs such as on(1). The pam_unix(5) module is no longer supported. Similar functionality is provided by pam_authtok_check(5), pam_authtok_get(5), pam_auth- tok_store(5), pam_dhkeys(5), pam_passwd_auth(5), pam_unix_account(5), pam_unix_auth(5), and pam_unix_session(5). The rpc.rexd service is managed by the service management facility, smf(5), under the service identifier: svc:/network/rpc/rex:default Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). Responsibil- ity for initiating and restarting this service is delegated to inetd(1M). Use inetadm(1M) to make configuration changes and to view config- uration information for this service. The service's status can be queried using the svcs(1) command. SunOS 5.10 5 Nov 2004 rpc.rexd(1M)
