To access via ssh the Tier-1 user interfaces (UI) first is necessary to connect to bastion.cnaf.infn.it, the CNAF gateway. To request an account on this gateway please follow the procedure available here: https://www.cnaf.infn.it/utenti-faq/.
UI are machines with batch system, grid middleware and file management tools. The general purpose UI is ui-tier1.cr.cnaf.infn.it but also experiment dedicated UIs exist:
- ui01-ams.cr.cnaf.infn.it
- ui02-ams.cr.cnaf.infn.it
- ui7-auger.cr.cnaf.infn.it
- ui-borexino.cr.cnaf.infn.it
- ui-cuore.cr.cnaf.infn.it
- ui-dampe.cr.cnaf.infn.it
- ui-darks.cr.cnaf.infn.it
- ui-enubet.cr.cnaf.infn.it
- ui01-foot.cr.cnaf.infn.it
- ui02-foot.cr.cnaf.infn.it
- ui-gerda.cr.cnaf.infn.it
- ui-herd.cr.cnaf.infn.it
- ui01-icarus.cr.cnaf.infn.it
- ui02-icarus.cr.cnaf.infn.it
- ui-juno.cr.cnaf.infn.it
- ui-km3.cr.cnaf.infn.it
- ui01-lhcb.cr.cnaf.infn.it
- ui01-lhcf.cr.cnaf.infn.it
- neutrino-01 (131.154.161.32)
- ui01-pamela.cr.cnaf.infn.it
- ui01-virgo.cr.cnaf.infn.it
- ui02-virgo.cr.cnaf.infn.it
- ui7-virgo.cr.cnaf.infn.it
x2go
Due to popular demand, we set up a x2go server on our main UI, ui-tier1.cr.cnaf.infn.it.
The connection still requires the user to cross our jump host (bastion.cnaf.infn.it) hence the user must setup the x2go client specifying to use a proxy server; xfce is the only option as session manager. See the included picture as a reference.
The support of this service is still experimental, we must evaluate the impact on both the jump host and the user interface itself: these are shared nodes and we are not sure the available resources are enough to stand the overhead of this service.
N.B. It is recommended to download the version 4.1.2.0-2018.06.22 of the x2go client, as it seems to work better than the latest one.
