The following tables collects the products tested so far during the UMD software provisioning process.


Product name Version Released in UMD update # IPv6 support Comments GGUS ticket

DPM from 1.8.8 on UMD3 and UMD4 YES Posible issues in SL6
https://ggus.eu/?mode=ticket_info&ticket_id=126286
FTS every version of FTS UMD3 and UMD4 YES

BDII 1.1.3 UMD3.0.0 UMD2.0.0 YES

VOMS-SERVER 2.0.11 UMD3.3.0 YES

UI 3.5.2-1 UMD3.x UMD2.x YES

StoRM 1.11.2 UMD3.2.1 PARTIAL srmv server does not bind to IPv6 socket. workaround available. https://ggus.eu/ws/ticket_info.php?ticket=99461
frontier-squid-3 ALL
YES squid2 is not IPv6 ready. squid3 is in Preview already, investigating if it's possible to introduce in UMD4.
argus-pep-api-c, lcmaps-plugins-c-pep, argus-gsi-pep-callout, argus-pepcli, XACML ALL
YES argus-pep-api-c, lcmaps-plugins-c-pep, argus-gsi-pep-callout, argus-pepcli rely fully on libcurl, hence is fully dual-stack. XACML

does not create sockets or do name lookups.


lcmaps-plugins-scas-client

PARTIAL lcmaps-plugins-scas-client does do a name lookup and socket creation and

is currently not IPv6 compliant, but can only connect over IPv4. This is fixed in our trunk and will be released together with a fix for OpenSSL 1.1, which is currently blocked by VOMS.


dCache
ALL

YES All currently supported versions of dCache support IPv6 in dual-stack and stand-alone mode.

Since dCache is a distributed system, it is possible to have a dCache cluster that comprises of a mixture of IPv4-only, dual-stack, and IPv6-only machines.  This, too, is supported, but obviously an IPv4-connected client cannot be redirected to an IPv6-only node. In such cases, dCache will make internal replicas or proxy the data.
