Re: [vpp-dev] Reg Failure in make pkg-rpm with stable/2206 branch
The default python version of centos is python2, you need to link python to python3, then you need to change some config so that you can use yum normarly. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[vpp-dev] #epoll problems with epoll
[Edited Message Follows]
Hi, Florin,
I'm using epoll with LDP, but sometimes I receive EPOLLRDHUP|EPOLLHUP
unexpectedly when the opposite side didn't send the FIN or RST packet. Here is
my vcl config, am Iconfiguring something wrong? Thank you very much for your
help.

Re: [vpp-dev] #socket-api get stuck in socket function
Hi， Florin Coras I found out that because I run the next program right next to the last one, the VCL didn't clear the last connection, so I get stuck in the socket function. Thanks a lot. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Thanks a lot. Actually, I want to customize a TCP congestion algorithm.

[vpp-dev] #vpp-hoststack how to change tcp congestion algorithm
Hi All, I have read the src code of TCP. I found that if I want to switch tcp congestion algorithm between newreno and cubic, the only way is to modify the src code. May I ask if my understanding is correct? Thank you very much. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] #socket-api get stuck in socket function
Thanks， I'm using LDP. When I use gdb to debug, it comes out with output as follows. I guess LDP recovers some libraries that gdb needs. When I switch to normal env, gdb runs correctly. How can I solve this, thanks. Correct output as follows. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[vpp-dev] #socket-api get stuck in socket function
Hi All ,
I'm trying to use nonblock socket with epoll.
I wonder why I sometimes get stuck in socket function when I use VCL .
Code as following:
printf ("before socket\n");
if ((c_fd = socket(AF_INET, SOCK_STREAM, 0)) < 0) {
perror("create socket fail.\n");
exit(0);
}
printf ("after socket\n");
The only output is "before socket",socket function even dosen't return.
Thank you very much
