git - Why is Ubuntu machine not being able to access Github? -


i can curl , wget google.com , other sites using https (not of them though).

github 1 of them. following commands don't work on ubuntu 14.04 machine:

  • this hangs indefinitely

    /usr/local/bin/git ls-remote git://github.com/sstephenson/rbenv.git -h refs/heads/v0.4.0

  • this results in: curl: (35) unknown ssl protocol error in connection github.com:443

    curl https://github.com

  • this results in: resolving github.com (github.com)... 192.30.252.130 connecting github.com (github.com)|192.30.252.130|:443... connected. unable establish ssl connection.

    wget https://github.com

  • openssl shows no certificate (is best hint?)

    openssl s_client -connect github.com:443 connected(00000003) write:errno=104 --- no peer certificate available --- no client certificate ca names sent --- ssl handshake has read 0 bytes , written 305 bytes --- new, (none), cipher (none) secure renegotiation not supported compression: none expansion: none ---

why github problem here? system blocking ssl traffic? possible firewall rule blocking traffic well. if that's case please point out don't have knowledge determine whether reason.

i can't git clone repos public , don't belong account (which have ssh keys for) either. can clone repos own github account want though.

here strace of command (notice hangs on last line)

openssl s_client -connect github.com:443 connected(00000003) write:errno=104

i suggest behind firewall middlebox restricts sites can access. in case of https restriction depends on target (it looking ssl handshake) , allow tcp connection close once "wrong" target detected, causing connection reset peer (errno=104). git instead blocking port 9418 connection attempt hangs.

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
