I can use TeamViewer to get into this remote host. It has sshd running. I would like to ssh to it. But it gives the system's IP as 192.168.xx.yy. How do I ssh into it?
View 1 RepliesI would like to access the ssh port of my office linux host from home. Unfortunately the host is located behind a NAT router. So, the IP address is not publicly available. There is however access to another internet host (Server) which is unfortunately only non-root access.
-Office PC (linux, root access) behind NAT (IP not public) but full Internet access.
-Server PC (linux, no root access) static and public IP and full Internet access.
-Home PC (linux, root access) behind NAT (IP not public) but full Internet access.

View 3 Replies View RelatedI am trying to monitorize an OpenWRT (Backfire 10.03, r23115) router from an Ubuntu server, but I am having some problems. I have installed Nrpe (2.12) on the remote host (OpenWRT), I have executed the program as a deamon (/usr/sbin/nrpe -d) but when I start the NRPE deamon, I don't get anything about NRPE executing netstat -at or ps -ef.I would need to install check_nrpe on OpenWRT to find out if NRPE is working, but I can't find any ipk package with it. Now, once in the monitoring host when I try to reach the remote host from the server:
/usr/local/nagios/libexec/check_nrpe -H ip_remote_host
I get: Connection refused by host
Even, trying with localhost:
/usr/local/nagios/libexec/check_nrpe -H localhost
I get the same error: Connection refused by host
I have installed Nagios Plugins and the check_nrpe plugin. I have edited the /etc/nrpe.cfg file:
allowed_hosts=127.0.0.1 ip_server
I don't exactly know if it is remote host's fault, monitoring host's fault or both.
I'm in a situation, that I have no access to one of my remote server. And I CAN'T EVEN INSTALL ANY SOFTWARE in any linux boxes to determine the remote OS name and version.Can you please enlighten me on how could I find out the OS version of remote host without installing any software or without login to that server.
View 1 Replies View RelatedMy 2Wire router/modem I got from AT&T for my DSL has port 3479 TCP open and I can't figure out how to close it. It's open to the entire internet. From a quick google search it's some port AT&T can use to update the modem's firmware or something.Consider how in bed AT&T is with government agencies it seems like a easy way for the government to get into my home network just by using what seems to me a backdoor put there by AT&T. Anyway to close this or secure it. Right now I'm using the hardware as my main router for my home network. I have Linsys I modded with DD-WRT. I'm thinking of re-configuring my network to use the DD-WRT router as the main router and the 2wire just as a modem. The 2wire is a hybrid modem/router and I'm kind of lazy and don't feel like re-configuring my entire network if I can just close the port.

It then places the folder on the desktop. However if I use any application that works with the file system, I can never see that folder. I know the physical location of the SSH folder can be traced into Home folder -> .gvfs (it is a hidden folder). However I want the SSH folder to be easily accessible on the file system. Something very similar to "Expand Drive" or "SFTP drive" in windows.

Q=What will this do?
A=This will read from /root/Desktop/iplist (or anywhere you want to put the list) after it reads the ip it will ping the ip two times. If the remote host is up then it will write the ip to a log. If the ping fails it will display it on the screen, write the ip to syslog so that you can do remote logging, and last it will send the ip by email to a user or a group of users.
Code:
#!/bin/bash

#test and wrote on centos 5.5 with sendmail
rm -f /root/Desktop/iplog #This will remove the good iplog
exec 9</root/Desktop/iplist #put full path the file where ip list is. Make sure that the ips are listed one per line.
while read -u9 ip
do
ping -c 2 $ip > /dev/null 2> /dev/null # ping and discard output
if [ $? -eq 0 ]; then # check the exit code
echo "$ip is up" >> /root/Desktop/iplog #write the ip of the hosts that are up
else
echo "$ip is down" # will show on the screen the ips that are not up

I am using mount.cifs to mount a remote samba share (both client and server are Ubuntu server 8.04) like this:mount.cifs //sambaserver/samba /mountpath -o credentials=/path/.credentials,uid=someuser,gid=1000.I mounted a user from local system with username and password with mount.cifs but the problem is that the user is part of multiple groups on the remote system and with mount.cifs I can only specify one gid. Is there a way to specify all the gids that the remote user has?
Mount the remote samba with multiple groups on the local system?Browse the mount from 1) with the terminal since I want to pass some files from samba as arguments to local programs.which runs through gvfs; but the newer gnome does not write to disk the ~/.gvfs anymore so I can't browse it in terminal. And the last solution would be NFS but that means that I have to synchronize the uids and gids on the local system with the ones from the server.
When I try to connect to my SUSE server from other one this appears: Remote host identification has changed. I deleted entry in know_hosts but it still working wrong, showing me this message. What could be the cause of this problem??
View 1 Replies View RelatedI am running
Code:
On my laptop (HPDV7), using DHCP for network access, KDE4.
I use Network Manager to manage wired and wireless connectivity.
I also have Samba server running for connectivity to Windows machines.
My router runs DD-WRT.
How do I tell this HPDV7 system to propagate a Host Name up to the router?
In the DD-WRT status screen, I see Host Name as "*" associated with the assigned IP address.
I cannot, for example, ping my HPDV7 machine from my windows machine, I assume because the router (also providing DNS for my network) does not provide the name to address translation.
I CAN ping the IP address directly, and Samba connectivity from the Windows machine to HPDV7 works.

I have a box (boell) running Fedora 10 sitting behind a firewall at school. I am able to freely ssh to and from this box to other computers (minion) within that lan. Outside of this network I cannot directly ssh to boell - I must ssh first to minion, then I can ssh to boell. I've spoken with the sysadmin and he's verified that the firewall permits ssh freely - i haven't had any issues like this with other boxes of mine there, so this isn't any surprise.
I have verified that the hosts.deny file is blank, iptables permits ports 22 (and 80) and I didn't see anything obvious in the sshd_config. I tried a tcp dump on the external host and boell while attempting to ssh from the former to boell. The packets appear to be acknowledged by boell, but this fails to lead to a connection. I've tried this process with external hosts in different locations with the same result. I have made few modifications to the default installation for F10, so perhaps there is some default somewhere I have to change. In any case, below I have attached excerpts of germane files.

i have a udp server running at port 60178. when i connect to it from localhost there is no problem. when i use the client from a remote host i am not able to connect. I changed my server firewall settings[Fedora 11] and added "udp 60178" to trusted ports but still nothing happened. I ran wireshark and observed that packets are coming to the server machine but server returns a "Port Unreachable" ICMP message and doesnt give the packet to the application.

The only way I've accomplished this in the past is by rebooting my slackware system.
I want to show you this scheme:MyPC -> router -> internet <- router <- Mom'spc I want to connect from my pc to my mom's pc using ssh. The first router doesn't represent a problem, but my mom's router does. Our IPs are both dynamic (anyway, I can easyly know them) and I have opened the port (TCP/UDP) 2100 on the router in order to open a gateway on mom's pc.The firewall is not enabled on the router, nor on mom's pc.
Granted all this, now I should be able to connect to that computer using ssh:ssh user@ip -p 2100 But I can't, I always get a "connection refused".if I do it on my intranet, I can connect without any problem (to others computers, of course, not mom's) What's the reason because I always get a connection refused?
