The certificate itself is issued for oss.deltares.nl, and older tools seem to only check that.<br /><br />Sadly, Centos 6 does not provide a more recent version of subversion and compiling one quickly leads to dependency hell.<br /><br />However, the WANdisco repository does maintain more recent versions and provides an easy way to install. <br />You can find instructions on <a href="https://tecadmin.net/install-subversion-1-8-on-centos-rhel">https://tecadmin.net/install-subversion-1-8-on-centos-rhel</a> ; I've tried it on a test machine and it works.<br /><br />Good luck !Wouter Jagers2018-04-10T12:26:52Zfailed to download delft3d ( SSL handshake failed: SSL alert received)KRIS Zhhttps://dlt-acc.firelay.cloud/en/c/message_boards/find_message?p_l_id=4041874&messageId=43925092018-02-26T11:47:16Z2018-02-26T11:47:16ZDear Community : <br /><br /> i cannot download delft3d when i use "svn co https://svn.oss.deltares.nl/repos/delft3d/trunk' delft3dtrunk "<br /><br /><div class="lfr-code"><table><tbody><tr><td class="line-numbers">1</td><td class="lines"><div class="line">[root@ip-172-31-6-166 ~]# svn co https://svn.oss.deltares.nl/repos/delft3d/trunk/ delft3dtrunk</div></td></tr><tr><td class="line-numbers">2</td><td class="lines"><div class="line">svn: OPTIONS of 'https://svn.oss.deltares.nl/repos/delft3d/trunk': SSL handshake failed: SSL alert received: Handshake failed (https://svn.oss.deltares.nl)</div></td></tr></tbody></table></div><br /><br />also failed when "svn list "<br /><div class="lfr-code"><table><tbody><tr><td class="line-numbers">1</td><td class="lines"><div class="line">[root@ip-172-31-19-177 ~]# svn list https://svn.oss.deltares.nl/repos/delft3d/trunk</div></td></tr><tr><td class="line-numbers">2</td><td class="lines"><div class="line">svn: OPTIONS of 'https://svn.oss.deltares.nl/repos/delft3d/trunk': SSL handshake failed: SSL alert received: Handshake failed (https://svn.oss.deltares.nl)</div></td></tr></tbody></table></div><br /><br /><br />OS: CentOS 6.9 <br /><div class="lfr-code"><table><tbody><tr><td class="line-numbers">1</td><td class="lines"><div class="line">[root@ip-172-31-6-166 ~]# lsb_release -a</div></td></tr><tr><td class="line-numbers">2</td><td class="lines"><div class="line">LSB Version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch</div></td></tr><tr><td class="line-numbers">3</td><td class="lines"><div class="line">Distributor ID: CentOS</div></td></tr><tr><td class="line-numbers">4</td><td class="lines"><div class="line">Description: CentOS release 6.9 (Final)</div></td></tr><tr><td class="line-numbers">5</td><td class="lines"><div class="line">Release: 6.9</div></td></tr><tr><td class="line-numbers">6</td><td class="lines"><div class="line">Codename: Final</div></td></tr></tbody></table></div><br /><br /><br />openssl:<br /><div class="lfr-code"><table><tbody><tr><td class="line-numbers">1</td><td class="lines"><div class="line">[root@ip-172-31-6-166 ~]# openssl version</div></td></tr><tr><td class="line-numbers">2</td><td class="lines"><div class="line">OpenSSL 1.0.1e-fips 11 Feb 2013</div></td></tr></tbody></table></div><br /><br />I try to upgrade openssl to 1.1.0f , not work. <br /><br />But it's OK when i use AWS AMI to download delft3d <br /><br /><div class="lfr-code"><table><tbody><tr><td class="line-numbers">1</td><td class="lines"><div class="line">[root@ip-172-31-22-46 ~]# svn list https://svn.oss.deltares.nl/repos/delft3d/trunk</div></td></tr><tr><td class="line-numbers">2</td><td class="lines"><div class="line">doc/</div></td></tr><tr><td class="line-numbers">3</td><td class="lines"><div class="line">examples/</div></td></tr><tr><td class="line-numbers">4</td><td class="lines"><div class="line">gpl-3.0.txt</div></td></tr><tr><td class="line-numbers">5</td><td class="lines"><div class="line">lgpl-2.1.txt</div></td></tr><tr><td class="line-numbers">6</td><td class="lines"><div class="line">src/</div></td></tr><tr><td class="line-numbers">7</td><td class="lines"><div class="line">tsvn-auto-props</div></td></tr></tbody></table></div><br /><br /><br />Thanks for any suggestion.KRIS Zh2018-02-26T11:47:16Z
