connection-timeout

In command below I enable file /dev/tcp/10.10.10.1/80 both for reading and writing and associate it with file descriptor 3: $ time exec 3<>/dev/tcp/10.10.10.1/80 bash: connect: Operation timed out bash: /dev/tcp/10.10.10.1/80: Operation timed out real 1m15.151s user 0m0.000s sys 0m0.000s This automatically tries to perform TCP three-way handshake. If 10.10.10.1 is not reachable as in example above, then connect system call tries to connect for 75 seconds. Is this 75 second timeout determined by bash ? Or is this system default? Last but not least, is there a way to decrease this timeout value?

I have a Tomcat application that uses MySQL, and Hibernate for ORM. The nature of our application demands that we have to pull and aggregate a lot of analytics data from a NoSQL store for each request , so we split the pulling and aggregating for each request into several tasks and delegate those to a thread-pooled executor service. When each thread performs a task, it needs to query / update MySQL regarding certain things so it borrows Hibernate sessions from C3P0 ( which we use for connection pooling ). Essential config : <property name="current_session_context_class">thread</property>

In $http docs it does not mention which is the default timeout in case of undefined. How can I know which is the default value for this configuration? At one time the default timeout for http requests was 30 seconds, but now many browsers perform "keep-alive" polling by default so in all practicality there isn't one. I've had http requests sit for several minutes before the server itself finally gave up and issued a timeout. 来源： https://stackoverflow.com/questions/37547229/what-is-the-default-timeout-for-angularjs-http-service-requests

I am writing a JAVA code to traverse FTP Location using Apache Commons Net FTPClient and getting output in an Excel file. the code execute correctly for approx 5 min but then gives an IOException: org.apache.commons.net.ftp.FTPConnectionClosedException: FTP response 421 received. Server closed connection. I am using commons-net-3.0.1.jar.

I am stuck in a problem, where my webservice (written in Spring boot) takes 5-6 minutes for a http response. I send a http post request from angular but chrome waits for only 2 minutes gives me a null response since there was no response from server. But server will give a response after 5 minutes. So how can I implement this scenario, since I think my http connection closes after 2 minutes and I want to extend it till 5-6 minutes. FYI I have already used rxjs timeout function but it doesn't work, the default timeout of 2 mins always wins. Thank you The issue is not with chrome You must be

I have a website using Microsoft SQL 2008 server over local network. Sometimes, SQL server machine is rebooted, and so the website fails to connect to the database. If the machine is up and running, it will respond fast. If it's down, there is no need to wait for 15 seconds. 3 seconds are ok. I want to display apologizes on the website when the database is not reachable, and want to do it fast. But setting Connection Timeout=3 in connection string seems having no effect. The page spends 22 seconds to wait before throwing SqlException on SqlConnection.Open(); . What's wrong with it? May it be a
