Moving A Compiled App To Another Machine

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

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.

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

Any suggestions why I am getting the error?

Hi,

I installed ghostscript via yum package manager. Later I wanted a newer version of ghostscript and compiled it from source. "make install" placed the gs executable file under /usr/local/bin/gs. This works if I run the command with absolute path, but if try to run gs, the shell will output

"-bash: /usr/bin/gs: No such file or directory"

if I echo the path variable it will display

/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin

If i run whereis it will give me the correct path
gs: /usr/local/bin/gs

How do I make it work so that typing "gs" will run the executable file from the /usr/local/bin/gs?

(I am using Centos 6)

Thanks.

We're unable to upgrade our environment beyond CentOS 5.10. This is a webserver that has certain reliances to the specific version of the OS, long story short.

I was asked to install a plugin for Redmine that requires at least ruby 1.8.7 so I cloned our VM as a new machine to test functional checkout. The problem is, the existing installation of Ruby was also installed ad hoc (not from any repo or yum methods) and it's currently at 1.8.5. The 1.8.7 version I tried to install gives me the following:
Quote:
# rpm -Uvf ruby-1.8.7.374-2.el6.x86_64.rpm warning: ruby-1.8.7.374-2.el6.x86_64.rpm: Header V3 RSA/SHA1 signatu NOKEY, key ID c105b9de error: Failed dependencies: rpmlib(FileDigests) <= 4.6.0-1 is needed by ruby-1.8.7.374-2.el6.x86_64 ruby-libs = 1.8.7.374-2.el6 is needed by ruby-1.8.7.374-2.el6.x86_64 rpmlib(PayloadIsXz) <= 5.2-1 is needed by ruby-1.8.7.374-2.el6.x86_64 ruby = 1.8.5-31.el5_9 is needed by (installed) ruby-irb-1.8.5-31.el5_9.x86_64 ruby = 1.8.5-31.el5_9 is needed by (installed) ruby-rdoc-1.8.5-31.el5_9.x86_64 ruby = 1.8.5-31.el5_9 is needed by (installed) ruby-ri-1.8.5-31.el5_9.x86_64
It appears as though this particular version was intended for CentOS 6 and, as I've known from previous experience, dependency hell is upon me. So, the question becomes, has anyone successfully upgraded ruby without tinkering with the OS version upgrade and, if so, might you have a HOWTO that prevents dependency hell? This, short of installing from source, is headed in the wrong direction real quick so I'm trying to stick with the RPM method. But, obviously, I'll listen to anything at this point.

I have 2 linux boxes Code:

HP-UX server1 B.11.11 U 9000/800

and Code:

 CentOS release 6.3 (Final)

I need to setup a password-less ssh. I could login from HP-UX to cent os but not other way.

Is it possible to use password less ssh both ways ? Is there any extra step in HP to setup keygen?

what I am doing

Code:

ssh-keygen -t rsa

copy the ~/.ssh/id_rsa.pub from client machine to ~/.ssh/authorized_keys on server machine

Hi,

Friends,

Good Morning to all. I have some queries about openssl. I googled for by query but i did not got the relevant answer, hence I came here and i am guaranteed that you gyes will help me definitely as you helped me before as well.

My scenario is I had one centOS 6 server which had openssl version as
Code:

 rpm -qa|grep openssl
openssl-1.0.1e-30.el6_6.5.x86_64
openssl-devel-1.0.1e-30.el6_6.5.x86_64

CentOS 6 provides php5.3 as default
Code:

yum list php

But I need php5.2, so i preferd to go compilation. It gave me some errors while doing make regarding openssl. I googled for it, gave solution of downgrading openssl.

As default openssl can't be removed, I prefered installing openssl-0.9.x through compilation with --prefix option. After doing I was able to compile php-5.2 successfully.

Now in my server there are followings installed.

Code:

[next02admin@NEXT02VMD02 ~]$ /usr/bin/openssl version
OpenSSL 1.0.1e-fips 11 Feb 2013 (the default one)

[next02admin@NEXT02VMD02 ~]$ /usr/local/bin/openssl version
OpenSSL 0.9.8e 23 Feb 2007 (the compiled one)

[next02admin@NEXT02VMD02 ~]$ php -v
PHP 5.2.10 (cli) (built: Jul  1 2014 00:39:27)
Copyright (c) 1997-2009 The PHP Group

[next02admin@NEXT02VMD02 ~]$ rpm -qa|grep httpd
httpd-tools-2.2.15-39.el6.centos.x86_64
httpd-2.2.15-39.el6.centos.x86_64
httpd-devel-2.2.15-39.el6.centos.x86_64

Now My question is,
1) Is it safe to use both openssl versions simultaneously.
2) Will it cause any vulnerability on my site (prod ENV), if it will affect to prod env, then to what extend.

Your replies will be very very appreciable. I will be very thankful to you.

so , without GUI. can be possible to install and use it?????

thanks in advance..

I have installed Linux 3.5 kernel and have compiled e2fsprogs as well. I have my own version of ext3 file system - lets say it is myfs. I have compiled myfs as well. Now I have few questions:

1.How to insert myfs module and where? When I do modprobe myfs (.ko file) it says module not found. When I simply do insmod myfs.ko it works but I am not sure where is it putting the .ko file. Also the displays I have added (on mkdir call) are not showing up (kernel debug level is also set to 8) when I try to create a directory in mounted folder

Makefile in myfs directory looks like this:

KERNEL_TREE ?= /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)

obj-m := iext3.o

iext3-objs := balloc.o bitmap.o dir.o file.o fsync.o ialloc.o inode.o \
ioctl.o namei.o super.o symlink.o hash.o resize.o ext3_jbd.o \
xattr.o xattr_user.o xattr_trusted.o acl.o xattr_security.o icefs.o \
transaction.o commit.o recovery.o checkpoint.o revoke.o journal.o

all:
make -C $(KERNEL_TREE) M=$(PWD) modules

clean:
rm -rf *.o *~ core .depend .*.cmd *.ko *.mod.c .tmp_versions *.markers *.order *.symvers

and I am compiling myfs from my own directory: /home/myname/soft/myfs.

Also, I don't see any ext2/ext3/ext4 directories in /lib/modules/linuxversion/kernel/fs/ -- not sure if this is right or wrong.

2.Mount is working fine. I can see myfs is mounted on /dev/sda3 by doing df -a. When I unmount It says - umount: /home/..../mnt: not mounted and then if I do df -a the file system is unmounted. This is strange as its unmounting but still throwing error.

Some Background: Directory where I have everything: /home/soft myfs/ mye2fs/ Linux-3.5/ mnt/

Step1: cd Linux-3.5 --> 1) make 2) make modules 3) make modules_install 4) make install 5) reboot

Step2: compile myfs (my version of ext3) and insert the myfs kernel module --> cd myfs/ --> make --> insmod myfs.ko

Step3: compiled mye2fs for mkfs

Step4: use mye2fs to create myfilesystem on a device --> mount --> test printk statements put under myfs modules

I have two centos 7 Server machines. "Machine-1" is having two NIC cards, one with public ip and another with private ip address. "Machine-2" is having a one NIC card with a private IP Address. how can i configure NAT on machine-1 to forward all TCP Traffic coming on public ip to the private ip of machine-2.

Pls give me a solve.its give me pain

Hi there. I have a problem installing the newest version of gnuplot which is 5.0. I downloaded it from this website (sourceforge): a source tarball. The Ubuntu 12.04 archive manager in my laptop placed it in the directory /home/alex/gnuplot-5.0.0.tar. I opened the directory/folder with a click and began reading manuals. The install procedure (read INSTALL.gnu) calls for issuing this command:

Quote:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
It is impossible to get to the directory gnuplot-5.0.0.tar via a terminal. If I type cd gnuplot-5.0.0.tar it says that this is not a derectory. If I omit .tar it does not recognize the name at all. I tried to rename it but after that I could not open it even with a click.

What shall I do?

Thanks, - A.
