I am using wget to download files and on multiple servers (same provider) I get "connection closed", socket errno 4, errno 4 socket error timed out, etc.
What can I do to show the provider it's a problem on their side? Or if I am wrong, how can I find out more about the cause?
Thank you for your help, much appreciated
I tried:
If it's a network problem, traceroute and pings are useful high-level tools to get a feel for reliability. If anything, a packet capture using tcpdump/wireshark will provide more details about the underlying protocol transmission. For example, if you see a bunch of tcp retransmits, that could indicate a problem with the network (anything from the actual wires to network hardware).
If you do a packet capture, you should start from the moments leading up to the socket closing and work backwards. Depending on how the socket is closed (which endpoint sends a rst or fin), that could also indicate whether the problem is with the network or application on either end.
What does your monitoring show? If you aren't monitoring the server, that's step #1. Are you seeing large CPU usage spikes? Large inbound traffic spikes? Large numbers of incoming HTTP requests? You could even set up a ping to your gateway, if you see lost packets that would most likely indicate a network issue.
Without any sort of data as to how your server is performing, we can't give you any sort of meaningful answer.
sir you do one thing,start download by wget and meanwhile u check command netstat -p tcp and show report to provider....
