Hi guys when im typing any command its giving error
-bash: /bin/ls: cannot execute binary file
plz telme how to resolve this im using fedora 13.plz helpme on this.iam waiting for ur replys

Sounds like you have mixed architectures. What do "uname -a" and "file /bin/ls" return?

sir im really in a mess plz helpme.
any command im typing its giving bash /bin/ls cannot execute binary file.
this is virtual mail server
when i type file /bin/ls
/bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (GNU/linux), dynamically linked (uses shared libs), for GNU/Linux 2.6.18,stripped


what does it mean.could u plz telme where is the problem how to over come this problem.this is our main server no backup server is present plz telme
how to solve this issue.

sir uname -a is also giving cannot execute file error plz telme how to solve this plz

Can you "cat /proc/version" ? What does that return?

You probably installed a 32-bit distro then updated it using 64-bit repositories. You probably need to reinstall.

this is virtual mail server
you do relies that running fedora on a server is a VERY VERY bad idea

but i guess IF YOU DO LIKE to reinstall the os on a working production server EVERY 6 MONTHS then ....

ALSO VERY IMPORTANT
SPELL OUT YOUR WORDS !!!!!!!!!!!!!!!!!!!!!!!!!!!
please IS NOT plz
and
you IS NOT u

also seeing as it looks like you "fubar'ed" the operating system
do your self a big favor and install a long life distro , one MEANT to be running a server like CentOS 5.5 or the not free RHEL 5.5 )

Thank you very much for ur support sir. I do realize fedora is not a good option but this setup is made by phillipene guy he left and i overtook it.so when im typing any command it was giving a error called cannot execute binary file.
so wht i did is logoff and logon again.but this time he is not accepting the password also.its giving permission denied error.GUYS this is running network.please telme wht should i do inorder to log in again.i suspect may be a virus or hacked issue.from last few days there was lot of spam was coming ....i cant figure out where is the problem.
SO PLEASE HELPME TO OVER COME FROM THIS PROBLEM.ANY SUGGESTIONS APPRECIATED.

virus NO
hacked / cracked YES ? maybe

are you logging in as root ?

but it dose sound like you have incompatible software installed

if this was not a VM on a MS windows ?? ( guessing) i would have you use the fedora install dvd in "rescue mode "


at this point if you can not even loggin your options are very limited

you can try the fedora install dvd but ?? i do not know if that will work on a VM ( fedora was never designed to do that )


try this reboot
durring the fedora DEFAULT 3 second delay countdown hit enter
then use the arrow key < down> to select the last kernel . boot from that one
or the <e> key to enter into " edit" mode and boot into single user mode ( google "single user mode" )

Please give us the output of

no password needed

While I understand the urge to have your problem fixed you should not spread your "/lib/ld-linux.so 2:bad ELF interpreter / cannot execute binary file" problem across multiple threads as you have done here, here and here. This is inefficient and dilutes efforts to help you.

I suggest FUP's go to http://www.linuxquestions.org/questi...e-mode-840957/.
