I fear a little reactivating it, at least during school time.
Same here. The nscd cache issue only occurred on my production networks. So re-enabling caching is a no-option here, too. > For libnss unfortunately we cant contribute since after a closer test on > our network we realized that our ISP doesn't allow multicast traffic at all > and the automatic discovery of printers happens only within a single > switch/router. On several setups libnss-mdns on clients and servers (i.e. on all machines with cupsd installed) works well. Anothe issue is that hostnames via libnss-mdns get propagated as <host>.local. When browsing CUPS servers with a webbrowser, this gets spoiled by wpad.dat. The .local FQDN should be included in the list of hosts to be connected to directly (and through squid). IIIRC, I committed that wpad.dat change on the d-e-c master branch already. Not 100% sure, though. > Regards > > Giorgio Greets, Mike > -- > Giorgio Pioda - Sysadmin SPSE-Tenero > Cell +41 79 629 20 63 > Tel +41 58 468 62 48 > > -- Sent from my Jolla
