Hi,
some little explanations here.
If you use an bloc ripe: read the email that we send when we add it to your servers.
Some informations inside this email:
Código:
IP de red : xx.xx.xx.xx (no utilizable)
IP de broadcast : xx.xx.xx.xx (no utilizable)
Netmask : 255.255.255.2xx
Is important that everybody use the right configuration because routage is not the same.
For an ripe NOT splitted we route as like this:
Código:
network xx.xx.xx.xx mask 255.255.255.xxx
ip route firs.ip.of.bloc.ripe 255.255.255.2xx ip.dedicated.server
All IP's in the bloc ( defination is made by the netmask ) take the same route.
( only if you add virtual macs we add for each IP the ARPA entry )
For an splitted bloc:
Código:
network xx.xx.xx.xx mask 255.255.255.255
ip route firs.ip.of.bloc.ripe 255.255.255.255 ip.dedicated.server
and when you splitt the bloc you must change the configuration too.
Código:
ip : ip1.from.your.bloc
mask: 255.255.255.255
broadcast: ip1.from.your.bloc
If you use wrong netmask or wrong broadcast: you can have some problems.
Than if you open and ticket:
http://www.ovh.es/soporte/declarar_incidente.xml
We announce that we run an diag.
If is our fault: you have to pay nothig.
if is not or fault: you will be charged with 20 Eu.
Why?
Because we spend our time to run checks and this cost money.
The admin can check by himself with an simple tcpdump before open an ticket the simple rules as here. This can permit you ALWAYS to see if something is wrong on your IP's:
tcpdump :
1- the icmp request for your ip came in - icmp answer goes out and came not back to you: problem on switch acl ( open an ticket : ovh side )
2- the icmp request for your ip are not came on your server:
problem on the router ( bad route or bad ARP entry: open an ticket: ovh side )
3- the icmp request for your ip came in the server but this one is not responding
problem on your configuration ( check your configuration : is not on ovh side )
For sdzzds is the 3nd rule.
The icmp echo requests are going in to the server but the server is not responding with icmp reply request.
I hope that the little explanations here can help sometimes for checking an problem.
Best regards,
Angie
