Hi boomer,

It seems there is some routing issue.Kindly share output of "#netstat -rn" command.

Hi Boomer,

Is there any router/firewall involve in this scenario, If yes, please ask you network team to check its routing.

Regards,
Asif Sharif

[Rajeev Shukla]

The rcp requires 2 way communication and from your pings there surely is issues with the communication between either the 2 servers or between the 2 vlans.
1. First confirm with the network team that the routing between the vlans is setup correctly.
2. confirm the you are using the right subnet mask in both the servers.
3. Try pinging someother machines/server from each servers.
can you also post the traceroute from both the servers to one another and also the ifconfig output of the interfaces.

Cheers
Raj

Ok Asif,
There is nthg at 10.1.4.xx end but will chk wid my netwrkng team at 10.1.1.xx end....

[Rajeev Shukla]

Your route and server 10.1.1.4 is correctly setup. From the other side i.e server 10.1.4.210 i would like you to ping servers in 10.1.1.x range.
1. Also send me the ifconfig lan0 output from both the servers please
2. run traceroute 10.1.1.4 from 10.1.4.210

[Rajeev Shukla]

Thanks, you seemed to be quicker than me.
It looks like the default route on 10.1.4.210 is not setup correctly. It cant even reach the default route.
From what i think is you wont be able to ping 10.1.4.1 from 10.1.4.210.
Please check with the network team as what the default route and subnet mask should be for the vlan 10.1.4.x

[Jeeshan]

ping reply shows, you have connectivity.

is there any firewall applied?

[boomer_2]

Hi Rajeev,Ahsan,

fine i will chk with my netwrk team and let u know asap....

[boomer_2]

hi Rajeev,
I changed my ip from 10.1.4.210 to 10.1.4.176 ..
nw m able to rlogin from 10.1.4.176 tp 10.1.1.4...


but m not able to do rcp from my 10.1.4.xxx n/w to 10.1.1.4 n/w....from any of my servers...

root #/tmp >rcp Wednesday.txt 10.1.1.4:/tmp
remshd: Login incorrect.

m getting the above msg for all of my 4 servers in 10.1.4.xxxx n/w....

i have 4 servers in 10.1.4.xxx n/w.....
and 1 server in 10.1.1.4 n/w.....

[Asif Sharif]

To resolve remshd: Login incorrect error, modify the 'hosts.equiv' and the '.rhosts' files to include each system's fully qualified name.

or put "+" in .rhosts file.

Regards,
Asif Sharif

[boomer_2]

Hi Asif,

my .rhosts entry in 10.1.1.4 is as follows :->

root #/ >cat .rhosts
+ cedge1 root
+ cedge2 root
+ 10.1.1.4 root
+ 10.1.4.176 root
+ 10.1.4.211 root


still m getting d same error...

[Asif Sharif]

just put "+" only in .rhosts file.
its looks like this

#cat .rhosts
+
#

Regards,
Asif Sharif

[boomer_2]

hi Asif,
one more thing nw m able to do rcp from 10.1.1.4 to all the 4 servers....


i.e. from 10.1.1.xxxx n/w to 10.1.4.xxxx n/w....


BUT M NOT ABLE TO DO RCP FROM 10.1.4.xxxx n/w to 10.1.1.xxxx n/w

[boomer_2]

Asif,
Its still not wrkng from 10.1.4.xxxx n/w....to 10.1.1.xxxxx n/w...
even after putting "+" in .rhosts file....

[Asif Sharif]

Boomer,

The error message is same?
remshd: Login incorrect
