I want to start a shell scripts(which generate traffic to test my network) at remote linux hosts from single linux local host.. If i start script at remote host through ssh, all traffic are sending from my local host also. It will create burden on my local host. If i terminate SSH connection, it stopping the script at remote host. Also i need to do ssh to all my remote hosts.
Is there any best way to do it?
My SSH client for remote machine will sometimes hang. I have to wait until the session is finished hanging, I guess, to login with SSH again. I would get some message about multiple users or something.
I haven't been able to login this time for over 1 day. It's started saying something about Tcl_InitNotifier: unable to start notifier thread. My host can access the machine locally to fix this, but what is going on? Why is this occurring?
Here is the login attempt:

I am having difficulty sending files from a remote machine to local one using

scp
. It is working the other way however. local > remote. I am using the verbose options

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
#wrote by Zach Underwood feb-12-2011
#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 "$ip is down" # will show on the screen the ips that are not up
logger -p auth.notice "$ip is down" # will write the down host to syslog
echo "$ip is down" | mail -v -s alert user@anydomain.com > /dev/null 2> /dev/null #will send mail users about host down

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.
I've been trying to make a cgi script that starts a program on a server and then shows the program on the servers screen. The cgi script is written in perl. I've been successful in making the program showing up on the screen through ssh by setting $DISPLAY to :0.0, I tried setting it to this in /etc/profile but when the cgi script ran nothing showed up on the screen. I tried having the script running it as a local user with "su - [user] -c [command]", this didn't help either.
In short what I'm trying to accomplish. When I press a button on a web page an slide show is supposed to start on a screen connected to the server.
I looked around for threads addressing this issue and some have come close to answering it, but I have yet to see a definitive yes or no. Anyway - Here's my issue:
Background:
I can SSH into my home computer (Ubuntu 9.04 running Gnome) from work (Win XP Pro) using RealVNC via Putty tunnels. This has been working flawlessly for me for awhile now. I was messing around in the terminal window and accidentally rebooted the linux box (home computer) while I was at work. No big deal I thought. So I re-start the Putty connection, and it is back up in no time. Then I try to start the VNC connection, and no go, connection refused. I remember seeing that in order for the VNC connection to work, I had to be logged into the Gnome desktop already on the Ubuntu box.
Question:
Is it possible to log in and start up a Gnome desktop session from the terminal command line in Putty so I can get the VNC connection back?
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 RelatedExecute putty to start a script on a remote linux server which requires user input The remote script does a read -p "Please enter name" NAME I can use plink to execute a script over SSH, the following attempts and problems are shown below :- Note the -load ns is to load a session that doesnt exist, ie ensure no defaults are used
1) plink.exe -load ns <ip_addr> -l <user> -pw <password> <script path/name> Problem) Doesn't allow/show user input, ie its non-interactive.
2) Add -t to allocate a pty :- plink.exe -t -load nc <ip_addr> -l <user> -pw <password> <script path/name> so now the user input can be seen, but I get Ctrl+H (^H) when backspace is pressed, ok if the user doesnt make a mistake!
3) Use putty instead with a saved session putty.exe -load "SavedSession" Get a new window opened, not a biggy, but not as nice. (b) saved session cannot be easily moved. (c) Get password prompt, cannot provide password like with plink, I know I know, use keys, but this is a closed, private network, and its easier not to bother with keys!I would like the SSH to execute in-line, that is from within the batch file/command line shell I am in, not prompt for username/password, run the linux script and allow prompts and delete/backspace to work.
Seemingly simple question, which yields slightly undesired results. Execute putty to start a script on a remote linux server which requires user input The remote script does a read -p "Please enter name" NAME I can use plink to execute a script over SSH, the following attempts and problems are shown below :-
Note the -load ns is to load a session that doesnt exist, ie ensure no defaults are used

So ideally, I would like the SSH to execute in-line, that is from within the batch file/command line shell I am in, not prompt for username/password, run the linux script and allow prompts and delete/backspace to work.
have fedora 10 and am having problems with ssh. For some reason I can't connect via a remote host to my ssh. Local network connections do work just fine. I have been looking for a log of what is going on but have not had luck seeing anything.Things I have tried:
-Modify hosts.allow to allow ssh to all
-generated rsa1 key identity tryed specifying that with the -i option on the guest computer
[code]...
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.
======== ssh from boell =======

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.

way to redirect the audit daemon message to a remote host I checked the auditd.conf and it's man page and find that the log location is specified by the line log_file = file_path and in the man page
Quote:
"log_file: This keyword specifies the full path name to the log file where audit records will be stored. It must be a regular file."
does this mean that the auditd does not have the function to redirect the logs to a remote hosts.
