You may be wondering why you have not seen any more news on the shutdown of DXCERN at the end of 1996. Unfortunately, the necessary preparations could not proceed as planned due to higher priority work to resolve performance problems on the MAILSERVer. We have therefore postponed the shutdown of this service by one month, till
January 31st, 1997.
This will then mark the end of centrally-supported Ultrix services apart from a limited facility to provide cross-compiler services for accelerator controls until the end of 1997. For more information about what you need to do, read this article, or simply type on DXCERN:
Do not hesitate to contact one of us if you have questions or problems with your migration from DXCERN to a new `home'.

Users who have not already obtained an account on one of the alternative public UNIX services should do so as soon as possible.
It is your responsibility to move any files you want to keep to another system. Don't leave it until the last minute, start now, since it will be painful and time-consuming to get back any files once the DXCERN service has stopped. Full dumps of the filebase will be made but recovering files will involve manual tape handling with delays of the order of days. Sorry - as you know we are very short of manpower.
You should also take care of your electronic mail setup. If your "preferred mail address" (PEM or EMDIR address) still points to DXCERN, update it to point to the service where you want to receive your mail from now on, e.g. mail.cern.ch. EMDIR addresses that still point to DXCERN and for which you have a forwarding address in $HOME/.forward on DXCERN will be changed to that forward address early in the New Year (unless we can easily recognize that the address is obviously incorrect, e.g. forwarding to CERNVM).
Like mail addressed to CERNVM, mail sent to DXCERN will continue to be delivered, for some time, with forwarding to your new mail address if it is registered in EMDIR.
Historically, quite a few systems have been NFS-mounting files from DXCERN either to get access to software packages or to users' home directories. System managers should check whether this applies to their system otherwise you could have a very bad surprise when DXCERN is switched off at the beginning of February. Remember that applications software is available on ASIS, either via AFS or NFS. See http://wwwinfo.cern.ch/dci/asis/primer.html for more information.

Here is a recipe for transferring all your files from DXCERN to the computer you are moving to. Please don't forget that there will be no binary compatibility between DXCERN and your new home, so you will have to recompile your private programs that you compiled on DXCERN on the computer you are moving to.
The following lines list the commands to execute with comments after the `#' sign (both of which you should not type in).
You will normally access your mail from one of the public UNIX services, CERNSP, HPPLUS or DXPLUS, from a Work Group server, or from your private workstation.
Use xwho or the Web to check whether you already have an account on a public UNIX service and the MAILSERVer. If you do, you will see something like
pine has a keyboard interface (although the mouse can be used for basic `cut and paste') and can be used from any type of terminal, even over slow lines. It is self documenting - look at the bottom lines of the screen for guidance. You can also obtain "Introduction to pine" at http://wwwinfo.cern.ch/umtf/1995/38/ for a short introduction.
netscape offers a full GUI X-based interface, and consequently needs an appropriate terminal and a good network connection.
You can try both of them out (but one at a time please) by sending mail to yourself at
Moving between use of pine and netscape is possible, but requires extra knowledge and care, so you are advised not to do this initially (see the Netscape FAQ at the URL http://wwwinfo.cern.ch/uco/netscape).
Unfortunately, your MAILSERVer password is physically separate from your AFS password. If you need to to know it, ask the UCO (tel. 74952) to reset it, then telnet mail.cern.ch and change it using the command passwd.
Check it is OK by issuing
do not set it to Firstname.Surname@cern.ch - this would be a circular definition !!!!
N.B. The address is updated only overnight, hence you need to wait until the next day before using it.
Firstname.Surname@cern.chIt will be routed to email@example.com
|Check the generic address by sending a mail to yourself before advertising it!|
N.B. The generic address Firstname.Surname@cern.ch is the address users should advertise to their friends.
When DXCERN is switched off, for a transition period we will forward mail addressed to
firstname.lastname@example.org the preferred e-mail address of the owner of this account, registered in EMDIR.
To profit from this, it is essential that your emdir address is updated to your new e-mail address.
The easiest way is to use the Web. From the CERN Home Page, take the link to `Directories (phone & email, services & people)', look for yourself and check that `Preferred e-mail(PEM)' points to the userid and computer where you want your mail delivered.
Look at the article ``How to Inspect and Update your Information in the Computer Centre Database (CCDB)'' in this CNL.
You must give your address, as a combination of the userid and computer system where you want your mail to be delivered, not your generic address.
Examples of correct addresses are
email@example.com for a UNIX user of the MAILSERVer firstname.lastname@example.org for a PC user of Microsoft mail Christiane.Ball@macmail2.cern.ch for a Macintosh Quickmail user email@example.com for a VMS userDo not enter an address of the form
Firstname.Familyname@cern.chin emdir. When mail arrives with an address of this form, the system looks in emdir to find out to which computer it should be delivered. If it finds a generic address, it won't be able to deliver the mail.
