Обсуждение: Canot access PostgreSQL via psql -h (Vmware Fusion)
Hi all;
I've fired up 2 CentOS 6.2 VM's via vmware fusion 5 (on a mac).
I disables selinux on both, and installed postgres 8.4.13 on both VM's
I set listen_addresses = '*'
and I added a trust entry for each server in the opposite server's pg_hba.conf file.
However I cannot access one server from the other one via psql -h <I.P. address>
I get the standard error:
psql -h 192.168.91.145
psql: could not connect to server: No route to host
Is the server running on host "192.168.91.145" and accepting
TCP/IP connections on port 5432?
I can ssh between servers, I see no entry in the postgres log per the connection attempt (I have log_connections set to
on)
Currently I have networking set to "share with my mac" or NAT. I tried setting networking to "Private to my mac" with
thesame results. Tried Autodetect (Bridged) as well, no luck
Can anyone help me debug this?
Thanks in advance
Hi, are there any firewalls up (check iptabled) ? try running telnet 192.168.91.145 5432 what is happening ? regards, Andreas On 08/24/2012 06:15 AM, CS DBA wrote: > Hi all; > > I've fired up 2 CentOS 6.2 VM's via vmware fusion 5 (on a mac). > > I disables selinux on both, and installed postgres 8.4.13 on both VM's > > I set listen_addresses = '*' > and I added a trust entry for each server in the opposite server's pg_hba.conf file. > > However I cannot access one server from the other one via psql -h <I.P. address> > > I get the standard error: > > psql -h 192.168.91.145 > psql: could not connect to server: No route to host > Is the server running on host "192.168.91.145" and accepting > TCP/IP connections on port 5432? > > > I can ssh between servers, I see no entry in the postgres log per the connection attempt (I have log_connections set toon) > > Currently I have networking set to "share with my mac" or NAT.

FWIW, on Linux I would start with `netstat -plnt` to see if the process was listening on the expected port and host address. -Kevin

Or even simpler, do ifconfig and make sure that you have the right IP address, followed by "ping 192.168.91.145" (assuming that's the right address) to see if your network is even running. Another thing to try: psql -h localhost Craig

"No route to host" doesn't have anything to do with whether there's
anything listening on the target port ... what's more likely is
that the OP mistyped the IP address, or else there's something
wrong with his network layout, interface netmask assignments,
that sort of thing.

I don't know about VMWare, but with VirtualBox if you set up two guests with NAT they are sharing the host's IP address as far as the outside world is concerned. So each can see the host and the outside world, but they can't see one another.

Hi! Try to check the iptables. If you don't need a firewall just disable it. As root, try the following:
service iptables status
service iptables stop
To disable it from starting at boot time, use:
chkconfig iptables off
