networking comps

tommycahir

hi all
i trying to network my laptop and my desktop but the just dont seem to be connecting right or something i using a cross over cable (that working ok) i set up my subnet mask to be the same on both comps 255.255.224.0 and the ip address are
laptop 149.153..130.123
desktop 149.153.130.124
i have them on the same workgroup and when i go to my network places i dont see any the shared folders on the other comp..
when i go
\\149.153.130.124 i just get the error saying that it not accessable
any ideas on whats wrong

Are you using XP? Go into the TCP/IP advanced settings for the LAN connection on both PCs and make sure NETBIOS is enabled...

also try connecting using \\computername rather than ip..

Make sure you don't have any software firewalls running, ZoneAlarm and such...

Mr. Fancypants

Can you ping between the pcs? Are you running any kind of firewall software?

tommycahir

no firewalls running
tried \\computername but still no luck
and the netbios is enabled yea both machines running xp home

Mr. Fancypants

Have you tried pinging the other machine? From the desktop go to a command prompt and type ping 149.153.130.123

tommycahir

no cant ping as it gives a
request timeout error from windows
and the following from redhat 8
icmp_seq=12 Destination Host Unreachable

PC = 192.168.100.1 /255.255.255.0

Lappy = 192.168.100.2 /255.255.255.0

Restart the PC let it load then restart the lappy while there connected, this should solve the connection issue, also what OS are the machines?

Thanks joePC

tommycahir

joe pc tried that with no luck before i posted the thread
as said above both machines running xp home but also have redhat 8 on pc

Mr. Fancypants

Go to a command prompt on each machine and type "ping localhost". This will make them ping themselves. Are you sure the crossover cable is working?

In XP Home go to Start->Connect To->Show All Connections and double click on your LAN connection to make sure it is active.

tommycahir

yea the loopback has no probs pinging themselves
and the local area connection is enabled
yea the crossover is working got it checked with a cable tester and had another two pcs running before this with it

Are you in Carlow IT by any chance? The class B network 149.153.0.0 belongs to them.
Like joe said you should probably use non-routable addresses in the 192.168.* or 10.* ranges for your lan.

tommycahir

yea in carlow it but i didnt think that having two ip address's in a small network like that would matter bout the address..
tanx ill try the 192.168 address's like joepc said

red vex

check to see if they are both sending packets. its quite common for this to happen. just kepp clicking on the workgroup and restarting both pcs
