Pinned September 26, 2024

August 19, 2010 in Uncategorized

This error can happen if you connect to an IMAP server without SSL/TLS (i.e. at port 143) but the server does not allow unsecure sessions.  Oddly enough, the Microsoft Exchange IMAP4 server will accept the connection, but will fail any login attempt with this error.  Here is a sample SessionLog: Connecting to IMAP server at […]

SSH SendReqExec — Interactive Commands such as “more”

July 26, 2010 in Uncategorized

Commands that assume an interactive user at a shell prompt should not be passed to SendRequestExec.  For example, the “more” command assumes there is a shell and that the user will press RETURN when another screenful of text is wanted.  It would be more appropriate to use the Unix/Linux “cat” command w/ SendRequestExec. To run […]

July 26, 2010 in Uncategorized

When a command is passed to SendReqExec that produces no output, such as “echo 1 > test.txt”, then do not try to read the channel (such as by calling ChannelReadAndPoll) because no data will be forthcoming and the channel read will timeout (as expected). The correct sequence of method calls would be to: Call SendReqExec […]
