Known Issues with Dialin Mode
•
The Telnet client for Dialin has a line ending issue (CRLF vs CR) that does not work when
trying to Telnet to a Windows PC. This line ending problem interferes with Windows login
authentication. Connecting to UNIX/LINUX servers does not seem to be affected by this issue.
The ADT Dialin Telnet connection has been tested with SUN, Linux, Cisco and GDC Products:
SCIP, SCES, ADT, SCM, SCMR, etc.
•
Once TELNET is established, there may be a buffer overflow if more than 50 lines of data are
received at one time. For example, if you login into a UNIX workstation and enter the command
"ls -l" for a directory that has 50 or more files, some data from the listing will be lost to the
user. Use the command "ls -l | more" to work around this issue. Since the Dialin
application is most likely going to connect to other network equipment with a CLI, this should
not be a problem.
