What + can I do? + A: Use the -f switch. This is not very clean however, since + modprobe is called on each cable detection query of ifplugd to + load a module for the network device. This is suboptimal. You + should probably run ifplugd only when the card is really inserted. + 2. Q: I am using the -f switch, but the kernel logs are getting + filled with messages like "modprobe: modprobe: Can't locate module + eth0". What can I do? + A: Make sure you have a line like alias eth0 off in your + /etc/modules.conf + 3. Q: When the cable is unplugged and the interface shut down it is + still available with ifconfig and markes as UP. Why this? + A: ifplugd cannot detect the link beat with a shut down interface + on certain (most as of kernel 2.4.19) network drivers. Thus + ifplugd enables the interface before querying the link status. + This may be switched off with -a flag. You might want to use it if + you have a sane network driver (e.g. eepro100). The subdirectory + patches/ in the ifplugd distribution includes a patch for the + 8139too 0.9.26 driver, which makes the driver compatible with -a. + Don't ask me how to apply this patch. If you don't know, you won't + need it. + 4. Q: Does it work with anything else than plain ethernet or wireless + LAN? + A: Certainly not, since the MII and ETHTOOL ioctl()s and the + wireless extension don't exist on other network device types. + 5. Q: I have a Realtek 8139 based network card. Everytime ifplugd + starts on bootup my machine freezes. What can I do? + A: This is a bug in the 8139too driver 0.9.25 (at least) shipped + with Linux 2.4.19, please upgrade to 8139too 0.9.26 (Linux 2.4.20 + or seperately at + [33]http://www.sourceforge.net/projects/gkernel/). + 6. Q: There are already laptop-net's ifd and miid, why did you write + your own daemon? + A: laptop-net was too integrated with its profile system and + didn't work on my hardware when I had a look on it. It seemed + easier to me to write a simple but feature complete replacement + than using laptop-net without most of the special features + disabled. I didn't know about miid when I wrote ifplugd, but in + any case ifplugd is much better than miid. For a comparison of + miid and ifplugd, have a look on + [34]http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=162763&repeat + merged=yes + 7. Q: I have two interfaces (e.g. WLAN and copper ethernet), both + controlled by ifplugd, and want to force the network traffic to go + over the faster one of them, in case both are available at the + same time. How can I do this? + A: A tool I wrote called [35]ifmetric might be exactly what you're + looking for. + + Lennart Poettering <mzvscyhtq (at) 0pointer (dot) de>, June 2005 + + $Id: README.html.in 124 2005-06-04 19:22:59Z lennart $ + +References + + 33. http://www.sourceforge.net/projects/gkernel/ + 34. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=162763&repeatmerged=yes + 35. http://0pointer.de/lennart/projects/ifmetric/ |
