Hi

May be i m a new to this

i m trying to connect through putty to my linux machine running on the VM ware , i get an erro "no route to host "
my Vmware settings "Ethernet - Bridged
Network connection is Bridged -Connected directly to physical network

when i run the cmd ifconfig-a my i.p is "16.138.59.189"

while i try to ping i get a response , but can't putty to it

pls advise

Even though if u have assigned ip to your linux machine it is not enough to connect to your linux machine, means through which port are you connecting to the machine that particular service has to be enabled.

For example if you are trying to connect through 22 port the you have to enable ssh service in your linux machine.

Turn on sshd by running any one of the following:
service sshd start
Verify ssh port is open
Make sure firewall is not blocking access to port 22

I believe the above posters are correct, but here is one more thing you can try if that doesn't work: Check /etc/hosts.allow and /etc/hosts.deny to see if SSH is being protected by TCP wrappers. (Don't worry if they're empty.)

--b9

i m sorry if this is a repetitive stuff


still unable to putty to linux which is running on vmare "error message No route to HOST

i m running on win xp ,, where i have installed Vmware inside the Vmware i have installed the Linux image .....VMWARE n/w connection is Bridged

ssh port is opened , no firewalls

Hello, csvinayak
I too have a problem with putty connect to my
VM Ware. And what I do :

1. Check ip`s and ports in my CentOS (VM Ware) and my PuTTY.

Result : no mistakes.

2. Check the state sshd in my CentOS (VM Ware):

[root@localhost ~]# /etc/init.d/sshd status
sshd (pid 3940 3936) is running...
[root@localhost ~]#

Result : sshd is running.

3. Check the state a port on CentOs for connection through ssh:

[root@localhost ~]# netstat -a | grep ssh
tcp 0 0 *:ssh *:* LISTEN
[root@localhost ~]#

or

[root@localhost ~]# cat /etc/services | grep ssh
ssh 22/tcp # SSH Remote Login Protocol
ssh 22/udp # SSH Remote Login Protocol
[root@localhost ~]# netstat -an | grep 22
tcp 0 0 :::22 :::* LISTEN
[root@localhost ~]#


Result: all is normal.

4. Check configuration my iptables:

[root@localhost ~]# /sbin/iptables -L -n
Chain INPUT (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0

Chain FORWARD (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

Chain RH-Firewall-1-INPUT (2 reference
target prot opt source destination
ACCEPT all -- 0.0.0.0/0 0.0.0.0/0
ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0 icmp type 255
ACCEPT esp -- 0.0.0.0/0 0.0.0.0/0
ACCEPT ah -- 0.0.0.0/0 0.0.0.0/0
ACCEPT udp -- 0.0.0.0/0 224.0.0.251 udp dpt:5353
ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:631
ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED
REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited
[root@localhost ~]#

Result: God dammed!! No rule for port 22! -> port 22 - forbidden!

4. Add rule for port 22 to my iptables:
Just insert it line by means of your favourite editor
in /etc/sysconfig/iptables:
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT

before:

-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited
COMMIT

Warning: your chaine name may be enother, because you have enother Linux. Curent chaine name you can see through /sbin/iptables -L -n (see above).

5. Check /etc/sysconfig/iptables:

[root@localhost ~]# cat /etc/sysconfig/iptables
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
:RH-Firewall-1-INPUT - [0:0]
-A INPUT -j RH-Firewall-1-INPUT
-A FORWARD -j RH-Firewall-1-INPUT
-A RH-Firewall-1-INPUT -i lo -j ACCEPT
-A RH-Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT
-A RH-Firewall-1-INPUT -p 50 -j ACCEPT
-A RH-Firewall-1-INPUT -p 51 -j ACCEPT
-A RH-Firewall-1-INPUT -p udp --dport 5353 -d 224.0.0.251 -j ACCEPT
-A RH-Firewall-1-INPUT -p udp -m udp --dport 631 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited
COMMIT
[root@localhost ~]#

6. Reboot you Linux and enjoy PuTTY
[root@localhost ~]# reboot

PS: If you want to thank me, just send me mail
for example:
[root@localhost ~]# echo "Thanks, you help me " | mutt buran83@gmail.com
[root@localhost ~]#

With the best regards !

I'm sorry but I don't get out. You cannot install vmware inside vmware. Generally you do as follows:

Host -> Vmware -> Guest

Do not use following

Host -> Vmware -> Vmware -> Guest

Dear Friend
Check your routing tables and also check your physical network

check whether root is permitted to login through ssh or not. I think "#PermitRootLogin yes" should be enabled to make your thing work.
