CHGSYSVAL SYSVAL(QAUTOVRT) VALUE(50)
Note: Since Version 4 Release 2, QAUTOVRT supports numeric values of 0
through 32500, and a special value of *NOMAX.
3. Verify that the network connection between the AS/400 server and the Telnet
client is active by using an application such as PING(VFYTCPCNN). If not
active, see your network administrator.
4. Verify that the virtual devices on the AS/400 server system that are used by
TELNET are defined to a subsystem under which the interactive TELNET jobs
should run. Use the Display Subsystem Description (DSPSBSD) command to
see which work station entries are defined to a subsystem. Use the Add Work
Station Entry (ADDWSE) command to define work stations to a subsystem.
For example, you could use the following command to allow all work station
types to run under the QINTER subsystem:
ADDWSE SBSD(QINTER) WRKSTNTYPE(*ALL)
5. Verify that the interactive subsystem (QINTER) is Active. TELNET connections
fail if the interactive subsystem is not active. In this situation, the system does
not write error messages to the QTVTELNET job log to show you the problem.
Use the DSPSBSD SBSD (subsystem name) command to verify that the
subsystem is active. Messages are not written to either QTVTELNET or
QTVDEVICE job log.
6. Verify that your local VTxxx client is configured to automatically wrap lines at
column 80 if you are operating in VTxxx full-screen mode.
7. Check for a TELNET user exit program registered to exit point
QIBM_QTG_DEVINIT format INIT0100, using the WRKREGINF CL command.
If there is a registered user exit program, check the TELNET server job log for
any errors related to that program. If errors exist, correct the errors in the exit
program or remove the exit program with the RMVEXITPGM CL command.
8. Ensure that your client is attempting to use the correct port to connect to
Telnet. Use CFGTCP or NETSTAT *CNN to determine what port Telnet service
is assigned to.
9. Use the CFGTCP command to verify that the port your client is attempting to
connect on is not restricted. Also look in the QTVTELNET job log for
messages indicating that the port that you are trying to use is restricted.
10. If you are attempting to connect using SSL Telnet, then in addition to the
above items, ensure that the Digital Certificate Manager (DCM), and one of the
IBM Cryptographic Provider products, are installed. Also, ensure that a valid,
non-expired certificate is assigned to the Telnet server
(QIBM_QTV_TELNET_SERVER).
Cause List B
1. Verify your authority to the virtual display device. If you receive message
CPF1110 when attempting to sign on the AS/400 system, you are not authorized
to the virtual display device. When the AS/400 TELNET server creates virtual
devices, the QCRTAUT system value is used to determine the authority granted
to user *PUBLIC. This system value should be *CHANGE to allow any user to sign
on using TELNET.
2. Verify that the QLMTSECOFR system value is correctly set if you are the
security officer or have *SECOFR authority.
Cause List C
1. Verify your word processing choice. If you experience problems when using
OfficeVision or the Work with Folders (WRKFLR) command, you may need to
444 OS/400 TCP/IP Configuration and Reference V4R4
