How does your /etc/nsswitch.conf look like and what's the content of /etc/hosts?<br>
Preferably of both systems, let's see if something is different.<br></blockquote><div><br></div><div>/etc/nsswitch.conf on working system:</div><div>passwd: files nis systemd</div><div>shadow: files nis</div><div>group: files nis systemd</div><div><br></div><div>#hosts: db files nisplus nis dns</div><div>hosts: files dns nisplus nis mdns4_minimal myhostname mymachines</div><div><br></div><div># Example - obey only what nisplus tells us...</div><div>#services: nisplus [NOTFOUND=return] files</div><div>#networks: nisplus [NOTFOUND=return] files</div><div>#protocols: nisplus [NOTFOUND=return] files</div><div>#rpc: nisplus [NOTFOUND=return] files</div><div>#ethers: nisplus [NOTFOUND=return] files</div><div>#netmasks: nisplus [NOTFOUND=return] files </div><div><br></div><div>bootparams: nisplus [NOTFOUND=return] files</div><div><br></div><div>ethers: files</div><div>netmasks: files</div><div>networks: files</div><div>protocols: files</div><div>rpc: files</div><div>services: files</div><div><br></div><div>#netgroup: files nis</div><div><br></div><div>publickey: nisplus</div><div><br></div><div>automount: files nis</div><div>aliases: files nisplus</div><div><br></div><div>/etc/nsswitch.conf on non-working system:<br></div><div>passwd: files nis systemd</div><div>shadow: files nis </div><div>group: files nis systemd</div><div><br></div><div>#hosts: db files nisplus nis dns</div><div>hosts: files nis mdns4_minimal [NOTFOUND=return] dns myhostname</div><div><br></div><div># Example - obey only what nisplus tells us...</div><div>#services: nisplus [NOTFOUND=return] files</div><div>#networks: nisplus [NOTFOUND=return] files</div><div>#protocols: nisplus [NOTFOUND=return] files</div><div>#rpc: nisplus [NOTFOUND=return] files</div><div>#ethers: nisplus [NOTFOUND=return] files</div><div>#netmasks: nisplus [NOTFOUND=return] files </div><div><br></div><div>bootparams: nisplus [NOTFOUND=return] files</div><div><br></div><div>ethers: files</div><div>netmasks: files</div><div>networks: files</div><div>protocols: files</div><div>rpc: files</div><div>services: files </div><div><br></div><div>netgroup: files nis </div><div><br></div><div>publickey: nisplus</div><div><br></div><div>#automount: files nis sss</div><div>automount: files nis</div><div>aliases: files nisplus</div><div><br></div><div>/etc/hosts on working system:</div><div><div>127.0.0.1<span style="white-space:pre"> </span>localhost.localdomain<span style="white-space:pre"> </span>localhost.localdomain<span style="white-space:pre"> </span>localhost4<span style="white-space:pre"> </span>localhost4.localdomain4<span style="white-space:pre"> </span>localhost<span style="white-space:pre"> </span>erdos</div><div>::1<span style="white-space:pre"> </span>localhost.localdomain<span style="white-space:pre"> </span>localhost.localdomain<span style="white-space:pre"> </span>localhost6<span style="white-space:pre"> </span>localhost6.localdomain6<span style="white-space:pre"> </span>localhost<span style="white-space:pre"> </span>erdos</div><div>150.108.64.52 <a href="http://dsm.dsm.fordham.edu">dsm.dsm.fordham.edu</a> dsm</div></div><div> <br></div><div>/etc/hosts on non-working system:</div><div><div>127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4</div><div>#::1 localhost localhost.localdomain localhost6 localhost6.localdomain6</div><div><br></div><div>150.108.64.57<span style="white-space:pre"> </span><a href="http://sobolev.dsm.fordham.edu">sobolev.dsm.fordham.edu</a> sobolev</div><div>150.108.64.65 <a href="http://mandelbrot.dsm.fordham.edu">mandelbrot.dsm.fordham.edu</a> mandelbrot</div><div>150.108.64.52 <a href="http://dsm.dsm.fordham.edu">dsm.dsm.fordham.edu</a> dsm</div></div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
Maybe the system's short name or FQDN is not mapped to an address correctly?<br></blockquote><div><br></div><div>I don't see where this could be happening but there are some differences from the 2 files you asked about. Note that the ipv6 option is commented OUT on the non-working system but could that be a reason? You can also see the hosts entry n in /etc/nsswitch.conf is slightly different. </div></div><br></div></div>
