Server :: Error: No Route To Host" Both Systems Ping Each Other And Firewall Is Also Disabled
Feb 2, 2010
using redhat on server machine and open suse on client machine.i have installed nfs server and and it is running properly but when i want to mount shares from my client machine it gives the following.
error. "mount.nfs: mount to NFS server '10.3.31.146:/share' failed: System Error: No route to host" both systems ping each other and firewall is also disabled. another problem is when i remotely access from my server machine to client machine it gives the following error ssh:connect to host 10.3.31.147 port 22:connection refused what can be the problem?
Both systems connected in same LAN based network . Both WAN live ips are connected through different modems. Problem is that , no system is able to ping or connect with other system with Live ip , though they are able to connect through LAN ip and both systes are accessable and also able to browse internet (google etc..) Ping error :-- Destination Host Unreachable.
I have a server that I can ping, and I can connect remotely with ssh to it. But when I try to connect to apache (port 80) I get "no route to host". But I can connect to localhost It's not just my client system that is having this problem but also systems that are on the same subnet There is no firewall running on the server route on the server
I installed ntop on our server, after installing it, i ran ntop as a daemon. shortly after we lost the ability to ssh into the server.tried restarting ssh, but it didn't work, so had to restart the entire server.Where should we look to find why ssh suddenly stopped?
the error ssh gave when we try to connect was like: ssh: no route to host what log files should i look at and what should i look for to find the cause of the error?
My domain [URL]... has recently been moved to a new server. Since then, I have not been able to download email. Email sent to the domain can be seen in /var/spool/mail/akwebsoft, just as on the previous server. However when I go to download the email, I get the following error message (in part) in my fetchmail logfile:
I have 2 clients (one IP 200.x.y.52 and another 200.x.y.47) in ADSL conection and a same gateway (200.x.y.1).
When the server send an email, the error "No route to host" appear. I used TELNET 200.x.y.52 25 (110 soo) and the error occurr in both servers and both directions. The Firewall was disabled .
Ok so I just installed Ubuntu 10.10 Server Edition. On the very first boot, everything seems to run perfectly. I can SSH into it from any remote computer with no problems. However, the installation of certain things calls for a system reboot, which 2 days ago never would have been a problem. But now for some reason, the SSH server only wants to work on the very first boot of a clean install. After I reboot it, I get the ssh: connect to host 192.168.0.180 port 22: No route to host error. The absurd part is sshd is running! I've even tried restarting sshd, restarting the server, and using both 64 and 32 bit installs. The only way I can get anything to connect to it is by using ssh localhost. It won't even let me connect using the IP on the local machine!
I am using fedora 14..i wanna create webservice in fedora 14...i am able to create sevice in server machine...but the client not able to get service from the server.it shows an error an i/o error has occured.no route to host.....we checked the ip address and port...i am able to ping the server...its connecting ...but it shows this error...?
I am using Fedora-10 on 64-bit quad-core xeon processors. I ran ssh-keygen and established passwordless connection between host-client and created a host file named lamhosts as follows:
172.16.122.11 cpu=4 172.16.122.21 cpu=4
where 11 is the host server and 21 is one of the nodes. When I executed 'lamboot -v lamhosts', it failed to boot nodes ssi:boot:base:linear: Failed to boot n1 (172.16.122.21). By googling, I found the error but couldn't yet find a solution.
I am trying to share directories between two F12 machines on a local network with a router box doing DHCP because not all machines on all the time. Web access is fine and local ping and ssh works but telnet doesn't. I have never succeeded doing mounts. So I have been searching for things to fix the above and have just tried rpcinfo. If I do this :
rpcinfo -p 192.168.2.2 it gives rpcinfo: can't contact portmapper: RPC: Remote system error - No route to host. Does that suggest that actually there is an installation problem? So I tried "yum provides portmapper" and that gives "No Matches found".
I'm setting up apache on centOS 5.5 and administering it from another host on my LAN(this web server has no Xorg). I can ping from the config host to the web server but not the other way. My network is quite a way from being set up so i'm just configuring the web server at the moment, the simplest way i can. It's just trying to get two LAN hosts both with 192.168.1.0/24 I.Ps to talk to each other using a router to connect them.
Here are the outputs of ifconfig and netstat -rn for the web server, the config host and the router:
The ifconfig -a and netstat -rn of the config host are: lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1
It has been years since I had to mess with sendmail (I prefer using postfix) - but I inherited a server that someone else configured. This machine is a webserver - but is running sendmail for the various webforms, etc. I want to configure sendmail on this machine to route ALL outgoing messages to the main email server. This means local users too. I have read through sendmail configurations for the past 3 hours, but it's mostly greek. Here is my current sendmail.mc file - could some kind soul tell me what I need to change (and WHERE)?
All I want is to be able to access files on one Ubuntu computer from another Ubuntu computer via a home wireless network. I have been at this for a week now. Scouring the web for answers and so far I have come up with this: Port 22 is open. I have both computers IP addr's via right clicking on the network icon-> Connection Information. ssh is installed and running. Both computers are listening on port22. But when I try Places->Connect to server, I get "no route to host". I'm not a networking guru and I'm at a complete loss on this.
I am trying to access a DVD mounted on a machine running Fedora12 (192.168.0.105). I thought this should be possible with NFS, but the above error message is what I keep getting, no matter what I try.
Here is my mount command: Code: mount 192.168.0.105:/mnt/dvd -t nfs /tmp/scaleo The Fedora 12 machine has the NFS server running, and the corresponding entry in /etc/exports is Code: /mnt/dvd *(ro)
I thought this might be a firewall problem, but it persists even if I turn firewalls off on both machines (client as well as server.) Also, doing Code: ssh 192.168.0.105 is OK, so what is wrong with the route?

I now tried Code: mount 192.168.0.105:/mnt/dvd -t nfs4 /tmp/scaleo and it seems the mount succeeded. So, instead of nfs, one must write nfs4?
I've just switched from xub to lub, and I must say it's a lot lot faster. There's just one really annoying problem (I have no idea if this is in any way related to LXDE or if it's just due to 10.04): Network Manager only starts about a minute after the rest of the desktop. So my system boots up, I log in, see the applet, but it is greyed out (it tells me "Network Manager is disabled" or something similar). After a minute (approx), it suddenly comes to life and connects me. Now, I think this only happens when I have:
A) set the wireless connection to "all users" B) given an empty password for the keyring
But when I cancel either of the two above, it doesn't stop it from happening. I've tried updating etc.. to no avail. I've also tried wicd, but for some reason installing wicd from synaptic doesn't remove Network Manager? Anyway, has anyone seen behaviour like this? Any suggestions for first steps to take to see where it's blocking?
I'm trying to ssh from my laptop to my desktop (both fedora 14) over a local network. I can ping my desktop and get responses, but if I ssh to it, I receive
ssh: connect to host 192.168.100.xxx port 22: No route to host
Many of mails sent from my mail server that are in Queue;The main reason is deffered by domains like yahoo,aol,etc.but there is one more error that i keep getting and that is Host Unknown,Below is an example from mail log,The catch is,test mail sent on the same email id sent from my personal mail from the same server i.e. url was deliveredHowever,another mail containing client information sent from customercare@mycompanysdomain ended up in queue.
There are more examples of the same,around 20 domain have the same problem.
Not sure if this post belongs here, but here it is.
Host: Win server 2003 Guest: Ubuntu server
Host: IS able to ping guest. Firewall is OFF. NOT able to access guest (which is a web-server) at browser. Guest: NOT able to ping host. Running a web server, you can check the website: (pegajosa.com) is running under that virtual Linux server.
Problem: guest needs to access host's sql database and/or any resources.
I install and configure the vncserver following and reading 1000papers, but all of this present the same problem; when i try to connect to my vncserver,recive this mesage: unable connect to socket: No route to host (113) The OS version is Fedora Core 14 and tigervnc-server i try different solutions including:Allow TCP connection modifing files /etc/gdm/custom.conf and /usr/share/gdm/gdm.chemas Disable SELinux removing iptables Here follow the vncserver configuration:
[code].....
The ip address of the vncserver is correct because i can do ssh on it. Where or what can i do?
I have a dual NIC firewall and everything works fine but only if I run the static route for the default gateway manually:route add -net 0.0.0.0 netmask 0.0.0.0 gw x.x.x.x dev eth1.Where eth1 is my WAN interface and x.x.x.x is my WAN IP. I've spent about 20 hours trying to figure out just how to get this static route to come up automatically upon reboot. I've read all the manuals and all that jazz.I've added the "up route..." or the "post-up route..." commands to the /etc/network/interfaces file but that does not work (although my other static routes work just fine from here). I've copied the relevant text and pasted it onto the command line to confirm correctness - everything with the command is fine.
I've also creates a static-routes file (and chmod +x, confirmed the correct permissions, etc) in /etc/network/interfaces/if-up.d/ and attempted to set the routes here (yes - using the "/sbin/route add -net." terms that work FINE from the command line). But that does not work either.
I have two machines: A.domain.com: (Old mail server): Red Hat 9 (Linux 2.4.20-30.9) B.domain.com: (New mail server): RHEL Client 5 (2.6.18-164.2.1.el5) (Both machines are in the same subnet and on the same switch). I wanted to test the new mail server by sending an E-mail message to it from the old one, but the maillog says
[code]...
I can ping from A.domain.com to B.domain.com and from B.domain.com to A.domain.com . I can traceroute -p 25 from A.domain.com to B.domain.com and from B.domain.com to A.domain.com. I can *telnet* on port 25 from B.domain.com to A.domain.com. BUT when I telnet on port 25 from A.domain.com to B.domain.com. I get "telnet: connect to address x.x.x.x: No route to host". The resolved IP x.x.x.x is correct by the way. So I see no reason why. it should fail to telnet on port 25 to A.domain.com.
I've got Ubuntu 10.04 on my laptop and have recently (within the last 72 hours) started having trouble connecting to other machines on my local network. I'm unable to ping both my router and a server set up in the room beside me.
1. I have tried pinging my server and router from other machines and it works fine. Accessing the server via HTTP works from all machines except for my laptop.
2. I am, however, connected to my router via wireless and can access the internet. Also, if I connect via an ethernet cable I am able to ping both my server and router, although I'd love to be able to go wireless.
3. I assume something's wrong with my wireless setup, but I really can't figure out what. Possibly related note: my wireless has been disconnecting unpredictably on my home network (WPA).
Let me know if you'd like to see any command output and I'll get it to you asap! I've got a Dell Studio 1558 w/ the dreaded Broadcom BCM4312 wireless controller.
Code: user@blue-skies:~$ cat /etc/network/interfaces auto lo iface lo inet loopback
