File Transfer Through UART Between Linux Host And Embedded Linux Target

I downloaded tslib-1.1.tar.gz and configured to cross compiled for my ARM target machine.

Was able to build and make install on my Ubuntu host machine successfully. On my taget machine I copied created a backup of my original libts-1.0.so.0.0.0 and SFTP'd from my host the version I built to my target machine and over wrote current libts-1.0.so.0.0.0 to keep the links.
reboot my taget and now get

QWSTslibMouseHandlerPrivate: ts_config() failed with error: 'No such file or directory'
Please check your tslib installation!

running ldd on the taget against the backup (.bu version) and new versions shows the same dependancies.

root@at91sam9m10g45ek:~# ./ldd /usr/lib/libts-1.0.so.0.0.0
libdl.so.2 => /lib/libdl.so.2 (0x4000b000)

/lib/ld-linux.so.3 (0x2a000000)

libc.so.6 => /lib/libc.so.6 (0x40016000)

Using nm verified ts_config() existed in the new version.

Any suggestions why I am getting the error?

Hi,
I try to co connect to a linux server and get following message:

Now I am trying to figure out what the problem is but I cannot connect to the target server. Is there any other way to connect except using ssh?
Thanx

Hi All,

Please can someone assist me on this, I enabled Selinux on Ubuntu 14.04 server and it's disabling ssh remote login for all users including root.

From the ssh terminal I get the following error:

ssh root@192.168.x.x
Last login: Wed Mar 25 12:39:02 2015 from 192.168.x.x
/bin/bash: Permission denied
Connection to 192.168.211.135 closed.


tail /var/log/auth.log

ubuntu sshd[1640]: Accepted password for root from 192.168.x.x port 51082 ssh2

ubuntu sshd[1642]: Accepted password for root from 192.168.x.x port 51089 ssh2

ubunt sshd[1640]: Received disconnect from 192.168.x.x: disconnected by user

audit2allow --all

sshd_t

This avc is a constraint violation. you would need to modify the attribute of either the source or target types to allow this access.

possible cause is the source user (system_u) and target user (unconfined_u) are different.

possible cause is the source role (system_r) and target role (unconfined_r) are different.

possible cause is the source level (s0) and target level (s0-s0:c0.c255) are different.

allow sshd_t unconfined_trocess transition.

Please how can I make this changes to take effect.

Thanks in advance.

I have a dual boot laptop with debian stable & Windows 7.

The HD partitions a
sda1: NTFS for W7
sda2: FAT32 (currently unused)
sda3: linux /boot
sda4: linux ext4, which is LVM with encryption

I've re-installed W7 and now need to recover the MBR & grub menu.

I've booted with the netinst usb in rescue mode, but it fails to mount the root partition /sda4:
"An error occured while mounting the device you entered for your root file system (/dev/sda4) on /target"

and /var/syslog shows:
Code:

rescue-mode: selected root device '/dev/sda4'
umount: cant umount /target: Invalid argument
isofs_fill_super: bread failed, dev=sda4, iso_blknum=16, block=32
EXT2-fs (sda4): error: unable to readsuperblock
EXT3-fs (sda4): error: unable to readsuperblock
rescue: mount: mounting /dev/sda4 on /target failed: Invalid argument

So it seems like something is wrong with the mount command?

Would appreciate suggestions how to solve this.

Thanks

I want to change the menu on a Suse 12 Enterprise system.
I edit the /etc/default zip12grub.conf file execure grug2-mkconfig. Then reboot the system and no changes occur. The zip12grub.conf seems like the correct file to update so I am at a loss as to what the correct process would be.

I am currently working on a sbc6000x board with linux 2.6.24 on it and would like to use the telnetd command from busybox (v1.4.2).
I can run the Telnet daemon on the board and try to connect to it from another computer but each time the connection close.

In the terminal of the computer i have : (i changed the ip with Ipoftheboard here)

Trying Ipoftheboard
Connected to Ipoftheboard
Escape character is '^]'.
Connection closed by foreign host.

I already tried to use the hosts.allow file with :
ALL : Ipofthecomputer

And i checked in /etc/initd.conf and Telnet is enabled.
I read that maybe the connection is closing because i don't have a user/password configured for the Telnet connection but i can't find where to configure them.

I must use Telnet, i can't use another solution like ssh.

Hi,
I am new in linux. I have following problem while running the codes of TORA in ns-2.35 in ubuntu.Can you please help me?

Dear all,

This is my current iptables (with default policy = Accept) and no rules.
Code:

[root@racnode1 ~]# iptables -L -v
Chain INPUT (policy ACCEPT 77072 packets, 7890K bytes)
 pkts bytes target     prot opt in     out     source               destination         

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         

Chain OUTPUT (policy ACCEPT 70306 packets, 129M bytes)
 pkts bytes target     prot opt in     out     source               destination         
[root@racnode1 ~]#

I have decided to allow only incoming network connection from my own subnet and hence

Code:

[root@racnode1 ~]# iptables -A INPUT -s 192.168.0.0/24 -j ACCEPT
[root@racnode1 ~]# iptables -L -v
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         
  178  9055 ACCEPT     all  --  any    any     192.168.0.0/24       anywhere            

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         

Chain OUTPUT (policy ACCEPT 186 packets, 316K bytes)
 pkts bytes target     prot opt in     out     source               destination         
[root@racnode1 ~]#

Noted that my default policy is still ACCEPT, hence I

Code:

[root@racnode1 ~]# iptables --policy INPUT DROP

===============================================================

Upon this, I have 2 issues

a) my iptables -L -v command can't display fully, i am stuck at below

Quote:
[root@racnode1 ~]# iptables -L -v
Chain INPUT (policy DROP 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
b) my ssh login is very slow

Quote:
login as: root
-- waited quite sometime before prompting me for password
===============================================================

If i removed revert the INPUT policy to ACCEPT, then everything will be fine as normal.

Why ?

Thanks and look forward to your advises.

Regards,
Noob ;(
