I switched from using cardctl to hotplug earlier this year. I didn't care to use any of the packages that do automatic detection of the network, so I set up a system just like cardctl scheme that allows me to choose which scheme to use manually. I no longer have pcmcia-cs installed at all. I just execute "hpscheme default" or "hpscheme bs9" and then plug the card in. It works from there (don't expect any beeps, though). I put this in /etc/network/interfaces: ------------------------------------------------------------------------ mapping hotplug script /usr/local/bin/map-scheme iface default inet static address ppp.ppp.ppp.ppp netmask 255.255.255.0 gateway qqq.qqq.qqq.qqq iface bs9 inet static address nnn.nnn.nnn.nnn netmask 255.255.255.128 gateway mmm.mmm.mmm.mmm iface dhcp inet dhcp ------------------------------------------------------------------------ The "mapping" stanza is what figures out which interface to associate with eth0, i.e., default, bs9, or dhcp. Here is the script /usr/local/bin/map-scheme: ------------------------------------------------------------------------ #!/bin/bash # Used with /etc/network/interfaces mapping function, which passes the # interface name as the first argument. /usr/local/bin/hpscheme get ------------------------------------------------------------------------ Here is the script /usr/local/bin/hpscheme: ------------------------------------------------------------------------ #!/bin/bash -e # Set or display a scheme, used by my hotplug setup to choose network settings # for PCMCIA card. Similar to what 'cardctl scheme' did in old pcmcia-cs pkg. DIR=/var/lib/hpscheme FL=${DIR}/scheme [ -d ${DIR} ] || mkdir -p ${DIR} [ -f ${FL} ] || echo default>${FL} USAGE="USAGE: $(basename $0) {get|put <scheme>}" if [ $# -lt 1 ]; then echo "$USAGE" exit 1 elif [ "$1" = "get" ]; then cat ${FL} elif [ "$1" = "put" ]; then echo "Current scheme is '$(cat ${FL})'; setting to '$2'" && echo $2>${FL} else echo "$USAGE" exit 1 fi ------------------------------------------------------------------------ You can also add dns-search and dns-nameservers lines to the stanzas in /etc/network/interfaces if you are using resolvconf, or add scripts to if-up.d/ and if-down.d/ to muck about with resolv.conf, or whatever you like. I've done both, though I just switched to resolvconf (thanks, Thomas!). In addition, of course, you need to set up hotplug, i.e., compile your kernel with the appropriate options and drivers, etc. -- Neil Roeth
