Thread: Want to use router's DNS server for local hostnames

-

can't ping hostnames or linux box

i'm configuring small office lan , 1 of machines on network running linux (ubuntu other distros) while others running windows xp. have run issue linux machine can't resolve hostnames of other (windows) machines on network , vice versa. interestingly, windows machines able resolve each other's names using 'ping' command can't see linux box. of machines able resolve domains outside of network (e.g. ubuntuforums.org).

have tried both assigning static ip's machines , having them assigned automatically via router's (a linksys wrt54g) dhcp server. limited networking knowledge, suspect has more dns server using in setup. using opendns dns servers realized servers have no idea how resolve local hostname. set dns server router address doesn't seem resolve local hostnames resolve outside network.

know can associate hostname ip address manually editing hosts file, seems tedious , wasn't dns invented solve problem? i'm wondering why windows machines can resolve each other's names linux machine can't. windows machines using different protocol? i've read netbios , wonder if windows machines using protocol find each other. windows 'ping' command double duty, using both netbios , dns? it's worth, 'nslookup' fails miserably on windows machines when trying resolve hostname linux machine gives further evidence other protocol being used.

ideally, i'd router act dns server , handle caching of hostname/ip pairs if that's possible. router (linksys wrt54g) can do?

i think getting confused between local area network (lan) , wide area network (wan). protocols quite different. long router acting dhcp server pc's incl. linux machine getting ip-address router , automatically within 1 common subnet, example 192.168.1.x each machine has different number x , router comes 192.168.1.1 - @ least that's how wrt54g acts.
communicate between various pc's need sure have same domain or workgroup setting. microsoft quite confusing naming calling "workgroup". can change calling "homenet". make sure pc's set (and need restart each machine after change).
running ubuntu 9.04 on 1 machine , correctly showing pc's in "homenet".
starting web-browser on machine sending wan- message router acts dns-server , forwards requests isp's server.
can check on windows pc going terminal mode (start/execute/cmd , enter "ipconfig /all". settings listed there.
1 more word of caution: unless have marked partitions or folders shared can not see/access on neighbour's pc.
hope not confusing!
cheers

¿conocéis este proyecto? fvdw-sl 15.3 para raspberry pi. convierte la raspi en un nas. http://plugout.net/viewtopic.php?f=31&t=1880 llevo tiempo intentando encontrar la forma de hacer que una de mis raspberry se comporte como un nas. configurando samba, minidlna, transmision, ftp, nfs, etc. pues con esta distribución lo tengo todo hecho. lo instalé ayer y me tiene soprendido. ahora mi raspi es un nas, hecho y derecho. caracterísitcas. - interfaz web. que cambia en función de si eres el administrador o un usuario. - gestión de usuarios. puediendo dar distintos permisos carpetas y funciones. - gestión de carpetas - vpn - ftp - nfs - webdav - varios servidores dlna como minidlna, townky, etc - varios gestores de descarga como transmision, mldonkey, etc - gestión de periféricos usb como impresoras o webcam. - gestión de cron para automatizar procesos. - creo que se basa en arch linux. por cierto, estoy creando una tarea para que me exporte un archivo txt del dis...

hello, im confused uno r3, uploaded code quite few months in uno, working fine. now without having altered of circuits, trying upload code changes,im getting strange error "avrdude: verification error, first mismatch @ byte 0x0000          0x0c != 0x62" i tried research able solve issue,  im running kind of fuse bit being changed or clock speed altered, im pretty sure did not play around these items. any people, please . . thanks taz Arduino Forum > Using Arduino > Installation & Troubleshooting > avrdude: verification error, first mismatch at byte 0x0000 0x0c != 0x62 arduino
