The master version of each of these 20 # configuration files is copied from the /etc/ftpd directory and placed in 21 # the /etc/ftpd/virtual-ftpd/hostname directory. If the /etc/ftpusers file 22 # exists it is appended to the virtual ftpusers file. If a virtual host lacks 23 # its own version of a configuration file, the master version is used. 24 # 25 # The -l (limited) option configures limited virtual hosting, which only 26 # allows a small number of parameters to be configured differently for a 27 # virtual host (see the virtual keyword on the ftpaccess(4) manual page). 28 # 29 # When the -b (banner) option is supplied, ftpaddhost creates a banner for 30 # the virtual host, useful to see that the virtual host is working. 31 # 32 # When the -x xferlog option is supplied, ftpaddhost creates a logfile entry 33 # which causes the transfer logs for the virtual host to be written to the 34 # specified file. 35 # 36 # Exit codes: 0 - success 37 # 1 - usage 38 # 2 - command failure 39 # 40 41 usage() 42 { 43 fmt=`gettext "Usage: %s -c|-l [-b] [ -x xferlog ] hostname root_dir"` 44 printf "$fmt\n" "$cmd" >&2 45 exit 1 46 } 47 48 verify_root() 49 { 50 # Verify caller has a real user ID of 0. 51 set `id` 52 if [ "$1" != "uid=0(root)" ] 53 then 54 fmt=`gettext "%s: Error: Only root can run %s"` 55 printf "$fmt\n" "$cmd" "$cmd" >&2 56 exit 1 57 fi 58 } 59 60 # Make directory $1 with mode $2 and ownership $3. 61 make_dir() 62 { 63 if [ ! -d "$1" ] 64 then 65 mkdir "$1" || exit 2 66 fi 67 chmod "$2" "$1" 68 chown "$3" "$1" 69 } 70 71 setup_complete_vhost() 72 { 73 fmt=`gettext "Setting up complete virtual host %s"` 74 printf "$fmt\n" "$hostname" 75 make_dir /etc/ftpd/virtual-ftpd 755 root:sys 76 make_dir "/etc/ftpd/virtual-ftpd/$hostname" 755 root:sys 77 78 fmt=`gettext "Configuration directory is %s"` 79 printf "$fmt\n" "/etc/ftpd/virtual-ftpd/$hostname" 80 81 # Update the virtual host configuration file. 82 vhconfig=/etc/ftpd/ftpservers 83 84 fmt=`gettext "Updating virtual hosting configuration file %s"` 85 printf "$fmt\n" $vhconfig 86 if [ -f $vhconfig ] 87 then 88 # Remove any existing entries for the virtual host. 89 sed "/^[ ]*$hostname[ ]/d" $vhconfig >$vhconfig.tmp.$$ 90 mv -f $vhconfig.tmp.$$ $vhconfig || exit 2 91 fi 92 93 echo "$hostname /etc/ftpd/virtual-ftpd/$hostname" >>$vhconfig 94 chmod 644 $vhconfig 95 chown root:sys $vhconfig 96 97 # Make copies of the master configuration files. 98 for file in ftpconversions ftpgroups ftphosts ftpusers 99 do 100 target="/etc/ftpd/virtual-ftpd/$hostname/$file" 101 rm -f "$target" 102 if [ -f /etc/ftpd/$file ] 103 then 104 cp /etc/ftpd/$file "$target" || exit 2 105 chmod 644 "$target" 106 chown root:sys "$target" 107 fi 108 done 109 110 # Append /etc/ftpusers to the virtual hosts ftpusers. 111 if [ -f /etc/ftpusers ] 112 then 113 target="/etc/ftpd/virtual-ftpd/$hostname/ftpusers" 114 cat /etc/ftpusers >>"$target" 115 chmod 644 "$target" 116 chown root:sys "$target" 117 fi 118 119 vhftpaccess="/etc/ftpd/virtual-ftpd/$hostname/ftpaccess" 120 rm -f "$vhftpaccess" 121 122 # Remove any existing root or logfile entries. 123 sed "/^[ ]*root[ ]/d 124 /^[ ]*logfile[ ]/d" $ftpaccess >"$vhftpaccess" 125 126 # Add the virtual host root. 127 echo "root $vhroot" >>"$vhftpaccess" 128 129 # Add a banner to show the virtual host configuration worked. 130 if [ -n "$banner" ] 131 then 132 # Add a banner entry if there isn't already one. 133 grep "^[ ]*banner[ ]" "$vhftpaccess" >/dev/null 2>&1 134 if [ $?
