To temporarily become root without root passwd, you need an entry in the sudo file that gives you
su OR su - Note the diff: su logs you in as root, but with your orig user's env, so root only cmds will not be avail. su - (note the space between su & '-') logs you in as root WITH root's environment. |
Where the sudo will be available and what changes I 've to do
in that file.plse reply. |
Using sudo util, you login to root acct as expalined, but using your persoanl non-root passwd.
For full details see man sudo the file is /etc/sudoers |
Hello, the file /etc/sudoers has a read permission for root only, so I cant view it.

Hai all,
I got a problem while logging in "/bin/login : error while loading shared libraries:libscript.so.1:cannot open shared object file : Error 23" . And also a error while switching between database The error is shown below "connectDBStart() -- socket() failed: errno=23 Too many open files in system Previous connection kept" Thanks & regards, Jothibass |
You won't have access to /etc/sudoers unless you're root. Only root is of course allowed to make other users "temporarily" root (using sudo) for the users he/she wants and only for certain commands.
This is logical: if it was not the case, anyone could change the sudoers file and give himself root access (security hazard). I remind you also of the fact that root access is something to be handled with extreme care. A sudoers file from another machine may be helpful as an example, but can't be used on your machine because you'll still need root access to overwrite the /etc/sudoers file. In other words Code:
cp /other/machines/sudoers /etc/sudoers #or mv Possible solutions: * Ask for root access on the machine to a "network administrator". If you're not allowed to have it, we'll need to look at alternatives to fix your problems without reverting to root access. * If there is no "administrator" of the machine who knows the root password, you can forcibly change it, providing you have physical access to the machine. This implies a system reboot, which may not be allowed for a critical production system and/or if other people are working on the same machine. Quote:
So, close some files. "lsof" (list of open files) can help you track down any open files. You said you wanted to install a patch. Software installation is also left up to root in many cases (especially if it involves installing programs into directories only writable by root, like /bin). It's likely that allocating sockets, ie for your DB, is also allowed only by root, because sockets can be used for network communication. Opening up your machine to the network, can leave it open to outside attack and thus must be "handled with care" (in other words: can be done by root only). |
Hai,
The problem "Too many open files in system" is observed when swiching from one database to other. While logging in I got a problem "/bin/login : error while loading shared libraries:libscript.so.1:cannot open shared object file : Error 23" After this msge the terminal got hanged, Cant do anything and I manually closed it.
