7: Services Web SSH/Telnet Copy and Paste There are security issues with letting a web page access the system clipboard, which is the main clipboard on a system that is shared between all applications. Because of this, browsers limit access to the system clipboard. The Web SSH and Web Telnet window provide copy and paste functionality via a right-click menu: the Copy option will copy what is highlighted in the Web SSH or Web Telnet window into an internal (non-system) clipboard, and the contents can be pasted into the Web SSH or Web Telnet window with the Paste.

With the exception of Internet Explorer, most browsers will not allow highlighted content from the Web SSH or Web Telnet window to be copied to the system clipboard (Internet Explorer will display a prompt confirming the copy). Likewise, most browsers will not allow content from the system clipboard to be directly pasted into the Web SSH or Web Telnet window with the standard Control-V paste key sequence. With some browsers, the user will be able to use the Paste from browser option in the right-click menu to paste content from the system clipboard into a text field in a popup, and after hitting Enter, the content will be sent to the Web SSH or Web Telnet window. Paste from Browser only handles a single line, and will strip out LF/CR.

Web SSH/Telnet Copy and Paste
There are security issues with letting a web page access the system clipboard, which is the main
clipboard on a system that is shared between all applications. Because of this, browsers limit
access to the system clipboard. The Web SSH and Web Telnet window provide copy and paste
functionality via a right-click menu: the Copy option will copy what is highlighted in the Web SSH or
Web Telnet window into an internal (non-system) clipboard, and the contents can be pasted into
the Web SSH or Web Telnet window with the Paste.
Support for copying and pasting content between the system clipboard and the Web SSH or Web
Telnet window will vary from browser to browser. With the exception of Internet Explorer, most
browsers will not allow highlighted content from the Web SSH or Web Telnet window to be copied
to the system clipboard (Internet Explorer will display a prompt confirming the copy). Likewise,
most browsers will not allow content from the system clipboard to be directly pasted into the Web
SSH or Web Telnet window with the standard Control-V paste key sequence. With some
browsers, the user will be able to use the Paste from browser option in the right-click menu to
paste content from the system clipboard into a text field in a popup, and after hitting Enter, the
content will be sent to the Web SSH or Web Telnet window. Paste from Browser only handles a
single line, and will strip out LF/CR.
Secure Lantronix Network Commands
Go to
SLC Network Commands
to view CLI commands which correspond to the web page entries
described above.
Date and Time
Use the Date and Time Settings page to specify the local date, time, and time zone at the SLC
location, or enable the SLC unit to use NTP to synchronize with other NTP devices on your
network. Note that changing the date/time and/or timezone, or enabling NTP may affect the user's
ability to login to the web; if this happens, use the CLI
admin web restart
command to restart the
web server.
The CLI
show ntp
command will display the current NTP status if NTP is enabled. The column
headings are as follows: the host names or addresses shown in the
remote
column correspond to
configured NTP server names; however, the DNS names might not agree if the names listed are
not the canonical DNS names. The
refid
column shows the current source of synchronization,
while the
st
column reveals the stratum,
t
the type (
u = unicast, m = multicast, l = local, - = don't
know)
, and
poll
the poll interval in seconds. The
when
column shows the time since the peer was
last heard in seconds, while the
reach
column shows the status of the reachability register (see
RFC-1305) in octal. The remaining entries show the latest delay, offset and jitter in milliseconds.
The symbol at the left margin displays the synchronization status of each peer. The currently
selected peer is marked *, while additional peers designated acceptable for synchronization, but
not currently selected, are marked +. Peers marked * and + are included in the weighted average
computation to set the local clock; the data produced by peers marked with other symbols are
discarded.
