More Information About FTP and MPE XL
This section describes in more detail MPE XL logon syntax and file system
behavior when using FTP.
MPE XL User Accounts
MPE XL user logon accounts are in the form:
ftp> USER sessname,username.acctname,groupname
The sessionname parameter ( sessname) is optional. Passwords may be
required for all three parts of the user account:
userpass,accountpass,grouppass
You can enter the user logon account and passwords together as follows:
ftp> USER session1,username/userpass.acctname/acctpass,groupname/grouppass
Press the return key when prompted for passwords.
The following example shows: no session, and a password for the account
only:
ftp> USER myname.myacct/acctpass
331 Password required for MYNAME.MYACCT/ACCTPASS [userpass][,acctpass][,grouppass]
Password: (press return)
230 USER LOGGED ON
ftp> pwd
251 ",MYNAME.MYACCT,PUB" is the current session.
NOTE Each password can only be entered once. For example, if you enter
the account password as part of the USER string, you cannot
re-enter it at the password prompt.
If you enter passwords as part of the logon string, they are
displayed in the message text of the password prompt.
Groups
An MPE XL user account can contain many groups, each containing files. A
group is comparable to a directory, but only to one level. Unlike UNIX
systems, the MPE XL file system is not hierarchical.
The MPE XL account manager can assign a default group for a user account.
For example, the user account MYNAME.ARPACCT is assigned a default group
PUB (with no group password). The user logon is as follows:
ftp> USER MYNAME/userpw.ARPACCT/acctpw
331 Password required for MYNAME/USERPW.ARPACCT/ACCTPW [userpass][,acctpass][,grouppass]
Password: (press return)
230 USER LOGGED ON
ftp> PWD
251 ",MYNAME.ARPACCT,PUB" is the current session.
Changing Groups.
The FTP CD command is not supported by the MPE XL FTP server. To change
groups you can log on again with a different group name, or specify the
group name in the file transfer or directory commands you are using.
For example:
ftp> GET TSCREEN.GROUP1 fscreen1
File Naming on MPE XL
The MPE XL file system is not case sensitive: file1 is the same file as
FILE1.
A fully-qualified MPE XL filename is in the form:
filename. groupname. account
Each part, ( filename, groupname, and account) is 1-8 alphanumeric
characters, beginning with an alphabetic character. To avoid file naming
problems, always explicitly specify resulting filenames in correct MPE XL
format.
Using Metacharacters
Be aware if you use metacharacters (wildcards) and specify a group and/or
account with MGET, the resulting filenames will be fully qualified MPE XL
file names (filename.groupname.account), a maximum of 26 characters,
including periods. If your system supports fewer characters than MPE XL,
the filenames may be truncated. Use the LS command to verify the set of
files you are transferring.
Both * and @ can be used as wildcard characters with the LS and DIR
commands.
Changing File Building Parameters
When transferring files from your system to MPE XL, you can use
file-building parameters following the PUT command string:
ftp> PUT localfile remotefile; buildparms
The supported build parameters are:
;REC=[-recsizebytes][,blkfactor[,[{F}][,{BINARY}] ] ] ]
{V} {ASCII}
[;DEV= device]
[;CODE= filecode]
[;DISC=[ numrec][,[ numextents][,[ initialloc] ] ]
The parameter REC= can also be specified in words (two bytes per word)
using a positive integer value. The default blkfactor size is one. For
more information about the BUILD command, see the MPE XL Commands
Reference Manual.
The default MPE XL file-transfer specifications for the PUT command in
the form of file-building parameters are:
ASCII: REC=-80,,F,ASCII;DISC=104800
Binary: REC=-252,,V,BINARY;DISC=104800
Examples.
The following example shows how to transfer a file to MPE XL with a
record size of 150 bytes:
ftp> PUT filex file2;REC=-150,,V,ASCII
In the following example, using only CODE=PROG defaults to a file of
fixed binary, with records of 128 words (which are the BUILD command REC=
defaults).
ftp> PUT filex file2;CODE=PROG
Supported MPE XL File Types
FTP only supports binary and ASCII file transfers, variable or fixed
record lengths, and Standard (STD) file type.
