Eigler 0 siblings, 1 reply; 5+ messages in thread From: John David Anglin @ 2021-03-24 19:46 UTC (permalink / raw) To: overseers Hi, A couple of days ago, git stopped working to clone or pull gcc to 132.246.10.86. I see the following error: -bash-4.4$ git pull --verbose Looking up gcc.gnu.org ... done. Connecting to gcc.gnu.org (port 9418) ... 8.43.85.97 done. fatal: read error: Connection reset by peer Git is still working from other sites. I suspect the issue might be because there is no dns lookup for hiauly3.hia.nrc.ca. But the following works: dave@mx3210:~$ nslookup 132.246.10.86 86.10.246.132.in-addr.arpa name = hiauly3.hia.nrc.ca. Could you check why the connect is being reset?

I have a tcpdump running for a little while, could you try right now? Is it possible that your ISP is interfering with this traffic?

I just tried a couple of pulls. It is possible that ISP is interfering. That's why I tested other sites.

That's why I tested other sites. OK, tcpdump indicates only TCP-SYN packets being received and replied-to by the server.

Puzzling. > % git clone https://gcc.gnu.org/git/gcc.git That doesn't work either: -bash-4.4$ git clone -v https://gcc.gnu.org/git/gcc.git gcc-11-new Cloning into 'gcc-11-new'... fatal: unable to access 'https://gcc.gnu.org/git/gcc.git/': OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to gcc.gnu.org:443 This seems to work: git clone https://github.com/gcc-mirror/gcc gcc-11-new and the following also works: git clone git://github.com/gcc-mirror/gcc gcc-11-new Thanks, Dave -- John David Anglin dave.anglin@bell.net ^ permalink raw reply [flat|nested] 5+ messages in thread
