You may encounter the following connection issues.
If, when establishing a connection to a Windows server, a dialog box appears with the message “Connecting to server…” but no subsequent connection window appears, you may need to configure the server with a Client Access License (CAL). For more information about licensing, see Licensing Your Product.
Sometimes reconnecting to a session with a higher color depth than that requested by Receiver causes the connection to fail. This is due to a lack of available memory on the server. If the reconnection fails, Receiver will try to use the original color depth. Otherwise, the server will try to start a new session with the requested color depth, leaving the original session in a disconnected state. However, the second connection may also fail if there is still a lack of available memory on the server.
Citrix recommends that you configure DNS (Domain Name Server) on your network to enable you to resolve the names of servers to which you want to connect. If you do not have DNS configured, it may not be possible to resolve the server name to an IP address. Alternatively, you can specify the server by its IP address, rather than by its name, but note that SSL connections require a fully qualified domain name, not an IP address.
cat wpad.dat | ./pacexec pac.js FindProxyForURL http://hostname hostname 2>&1 | grep “undeclared variable”
If you get no output, there is a serious issue with the wpad.dat file on the server that you need to investigate. However, if you see output such as “assignment to undeclared variable ...” you can fix the problem. Open pac.js and for each variable listed in the output, add a line at the top of the file in the following format, where “...” is the variable name.
If a session does not start until you move the mouse, there may be a problem with random number generation in the Linux kernel. To work around this, run an entropy-generating daemon such as rngd (which is hardware-based) or haveged (from Magic Software).
