X29 Access

Users of this service are strongly recommended to use, where possible, one of the following alternatives:

a)

TELNET (TCP/IP) protocol is strongly recommended - as most remote HEP sites now have much more performant TCP/IP links to CERN.

i.e. TELNET HOSTNAME.CERN.CH

e.g. CERNVM.CERN.CH or VXCERN.CERN.CH

b)

People using X29 access locally from home are strongly encouraged to use the ACB service which is much more performant and generally cheaper - particularly from France.

Please see ``User Guide to Terminal Access from home'' available from UCO or XFIND ACB on the central computers.

Users who wish to continue using X29 should note the following:

The recommended numbers for access to IBM and VXCERN do not change.

CERNVM ( full screen mode) (0)2284681140522

VXCERN ( full screen mode) (0)2284681140550

However, access to other CERN hosts via service 10 (line mode) and 12 (full screen mode) i.e. (0)2284681140510/12 have moved to a DECserver.

Direct telephone access (via a terminal and modem)

Direct terminal access via certain restricted telephone numbers ( without callback) will move to a DECserver. At the same time the four lines with prefix 782 will be supressed.

In both cases the X29 number and phone number remain the same and the user is connected to a DECserver and should see the following message:

DECserver 200 Terminal Server V3.1 (BL37) - LAT V5.1

Type C VXCERN or C TAGIBM etc to connect.

Please type HELP if you need assistance

Local>

The HELP service is very complete. Currently no password is used and it is only necessary to type C Hostname (e.g. C TAGIBM for fullscreen access to IBM).

Use SHOW SERVICES to see hosts/services available. CERN hosts not listed may be reached indirectly using C TELNET.
