Ncmpcpp Problems.

Hello all,
I am trying to execute Code:

ssh $a@$b mkdir abc

in a shell script where, a and b are variables
a=username and b=server.ip
It is giving me an error Quote:
ssh connect to host port 22 connection refused
why am I getting the error?? ssh does not accept variables? Can anyone help.
Thanks in Advance

I have a hostlist and there are several hosts. I want to use ssh to connect to them. I want to see whether the host is available or not by the time length of ssh takes. If it take long than 5s (which means it is not available). Then stop it, and ssh to next host. Once a host is available, then output the name of host. I previously use nmap, but the IT security told it is not allowed to install it on the desktop on campus.
Code:

    HOSTS=`cat $host_list`
    for line in $HOSTS
    do 
    ssh -o ConnectTimeout=5s $line true >> /dev/null
    RESULT=$?
    if [ $RESULT -eq 0 ]
    then
    echo $line > succeed.txt
    else
    echo $line > fail.txt
    fi
    done

The above script is all I can do.
The problem is when it is failed, I want to redirect the error message
Code:

ssh: connect to host c28-0112-05.ad.mtu.edu port 22: No route to host

. But I still get the error message.

Hello,

I try to use a ftp daemon and a Telnet daemon with inetd and the BusyBox v1.19.0 on a linux 2.6.24.

When running inetd and then checking what is listening with "netstat -an |grep LISTEN" i have :
Code:

netstat: /proc/net/tcp6: No such file or directory
netstat: /proc/net/udp6: No such file or directory
netstat: /proc/net/raw6: No such file or directory
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN

tcp        0      0 0.0.0.0:21              0.0.0.0:*               LISTEN

tcp        0      0 0.0.0.0:23              0.0.0.0:*               LISTEN

ftp port 21 and Telnet port 23 seems to be listening.

My inetd.conf file is :

Code:

#<service_name>    <sock_type>    <proto>    <flags> <user>     <server_path>     <args> 

21 stream tcp nowait root ftpd ftpd /etc
telnet            stream        tcp        nowait    root    /usr/sbin/telnetd

I have no rule in my hosts.deny so nothing should be stopped and i have no iptables firewall in place too.

When typing "ftp://ipofthetarget" in a web browser i have a error :

Code:

504 Gateway Timeout
Gateway timeout expired while waiting for server response.

And when trying to Telnet from another computer or "Telnet localhost" from the board i have :
Code:

# telnet 10.2.29.201
Trying 10.2.29.201...
connected to 10.2.29.201.
Escape character is '^]'

Connection closed by foreign host.

This would mean that the connection for Telnet exist but why is it closing ?

Thank you for your future answers !

UPDATE 1 :
If i try to run telnetd like this :
/usb/sbin/telnet -l /bin/sh
i can connect anonymously from another computer, not perfect because i would like a user/password but still of use.
The problem with the ftp daemon still exist.

UPDATE 2 :
Trying from Windows cmd or linux terminal : ftp ipofthetarget seems to work
Not perfect because i would like a user/password too but still of use.

I am still open for suggestion for the user/password thing. I am not deleting the thread in case someone interested about this exist.

I have install vsftpd and start it , but when when to try it by "ftp localhost" , but not work , would advise what is wrong ? thanks


#ps -ef |grep ftp
Code:

root     29896     1  0 10:53 ?        00:00:00 /usr/sbin/vsftpd /etc/vsftpd/vsftpd.conf
root     29899 23821  0 10:53 pts/0    00:00:00 grep ftp

# ftp localhost
Code:

Connected to localhost (127.0.0.1).

Hi!

Im trying to use scp to copy changed httpd.conf files to 2 remote machines (the script is executed in one machine from remote and the result is copied to the both).

scp -vvv first_machine_name@ip_address:filename \second_machine_name@second_ip_address:/usr/local/apache/conf

Using RHEL 5.7 with mremote in windows 7 im getting this error:

ssh: connect to host <ip address> port 22: Connection refused

How can I solve it ? Thanks.

Hi,

I have a CentOS 6 machine [Machine X], which I connect to using a putty client or from another CentOS 6 machine.

Now, the machine X intermittently sends a connection reset message to all SSH sessions -

Code:

Read from remote host 1.1.1.1: Connection reset by peer
Connection to 1.1.1.1 closed.

I have switched off the firewall on the machine & there are no session timeout values set.

How do I find out what is causing this issue?


Thanks

Hello,
I can't get nfsd start at boot on openwrt linux.

I followed this guide:
http://wiki.openwrt.org/doc/howto/nfs.server

but when I turn the computer on:

Code:

root@OpenWrt:~# showmount -e localhost
clnt_create: RPC: Program not registered

Code:

root@OpenWrt:~# dmesg | tail
[   22.252000] IPv6: ADDRCONF(NETDEV_UP): eth1: link is not ready
[   24.228000] eth1: link UP - 100/full - flow control off
[   24.244000] IPv6: ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready
[   30.124000] svc: failed to register nfsdv3 RPC service (errno 5).
[   31.588000] device eth1 entered promiscuous mode
[   31.596000] br-lan: port 1(eth1) entered forwarding state
[   31.600000] br-lan: port 1(eth1) entered forwarding state
[   31.652000] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
[   31.684000] eth1: link UP - 100/full - flow control off
[   33.604000] br-lan: port 1(eth1) entered forwarding state

but if I do
Code:

root@OpenWrt:~# /etc/init.d/nfsd start
root@OpenWrt:~# showmount -e localhost
Export list for localhost:
/mnt/3tb *

so it works well, but I look at dmesg
Code:

root@OpenWrt:~# dmesg | tail
[   24.228000] eth1: link UP - 100/full - flow control off
[   24.244000] IPv6: ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready
[   30.124000] svc: failed to register nfsdv3 RPC service (errno 5).
[   31.588000] device eth1 entered promiscuous mode
[   31.596000] br-lan: port 1(eth1) entered forwarding state
[   31.600000] br-lan: port 1(eth1) entered forwarding state
[   31.652000] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
[   31.684000] eth1: link UP - 100/full - flow control off
[   33.604000] br-lan: port 1(eth1) entered forwarding state
[16642.280000] svc: failed to register lockdv1 RPC service (errno 124).

I tried several times
Code:

root@OpenWrt:~# /etc/init.d/portmap enable
root@OpenWrt:~# /etc/init.d/nfsd  enable

and reboot but, again, I have to start nfsd manually after every reboot.

What am I doing wrong? On Attitude Adjustment I never had any issue.

Please help!

Hi All,

Please help me. I'm following the book - ' DNS and BIND, 5th Ed By Paul Albitz, Cricket Liu '. This RNDC is driving me crazy. I spent all day trying to configure rndc. Tried every possible combination in config files, but I just cant control remote server. Tried many tutorials from google, nothing helped. LQ is my last hope.

So, my story goes like this...

What I'm doing wrong? Please Help!!!

Hi all.
RHEL 6.0 in Virtual Box, network is ok, it can resolve all repos (f.e. dl.fedoraproject.org, nginx.org),
but when I'm trying
Code:

# rpm -Uvh http://nginx.org/packages/rhel/6/noarch/RPMS/nginx-release-rhel-6-0.el6.ngx.noarch.rpm

I get:
Code:

curl: (6) Couldn't resolve host

When I'm trying with ip instead name:
Code:

curl: (22) The requested URL returned error: 404

Only rpmforge repo enabled, but it can't find any packets for install/update.

What can I do?
Thanks.

Hi, I know that it is possible to get the last background pid using the $! command, however when I use it in my QT application I got a wrong result. Below follows an example where this procedure works
Code:

[linux@localhost ~]$ (sleep 6 && echo "A test") &
[1] 3312
[linux@localhost ~]$ echo $!
3312
[linux@localhost ~]$ A test

Now my Qt application, where I got a wrong result:
Code:

./dbsync &>/dev/null &
[1] 5047
[linux@localhost comm5]$ echo $!
5047

but using the ps command it is possible to verify that the pid related to the right process is not the 5047 but 5050.
Generally it is the process that comes with the command Code:

echo $!

added of two.

I use QCoreApplication in my program. I do not know if it has something to do with this error.

Any advice is welcome
