    New Shells....

    fse shell: The shell that is constantly updated with a listing of adult websites and can do nothing but deliver the content to the user environment VIEWER binary as argument in loop.. Might be pretty popular.

    ARRRRRRRRRRRRRGH!

    The lesson here is: * Don't run stuff you don't know. * Don't run things you don't monitor. * Don't trust an internal monitor. * Keep up to date on software you use. * Audit software you use. * Know what software you use. * Always doubt. All of this points to the long argued admin assertion of...

    Ethical or not?

    ~ 98 I had a similar experience which can be compared unfavorably to the OP's doctrine. I inherited a k12 network with personally marginal unix skills that was utilizing ancient RH installations for a potpourri of services , FTP, mail,DNS, etc.. The students that had put the network together...

    User Directory Ceiling

    Very difficult IMO to limit ssh access in the way you describe. This is just an encrypted shell session over a tcp connection after all. Unlike ftp which was created with the idea of access control based on file system traversal, ssh is a replacement for the old r services (*login and *sh)...

    Search a File

    Line oriented searches are going to be best accomplished using stdio friendly functions as Salem suggested except in very special cases. Otherwise if all you need is an offset you could read blocks of data using fread or read and record an offset counter. Might be faster, who knows...

    ssh hammering help

    Dictionary attacks are painful but not prohibitively so. A couple of pointers. * Root cannot login via ssh. * Users must use keys (no password based auth) and policy regarding strong passwords and key safety are enforced. * Limit connects to port 22 in kernelspace via netfilter and plug in a...

    Machine compromised

    The 'I'm rooted three step'. Remove this machine from any network. Boot from knoppix or some purpose built forensics bootable. Do forensics analysis and follow up. HTH

    LVM recovery

    Okay. There are three logical layers to LVM: physical, volume, and logical. If you use pvscan,vgscan,and lv? to decipher your problem and then have questions, please let us know. Please post error messages and other errata. In the meantine: http://www.tldp.org/HOWTO/LVM-HOWTO/

    libdvdcss and what else?

    Umm...Maybe you should install the software that depends on the library after installing the library? Just a thought.

    socket() hangs up in Linux

    Try without the IPPROTO_TCP 3d arg. Try 0. Try (ks?)trace and look for the socket return via your kernel tracing mechanism rather than trying to step through with gdb. Off the top of my head...

    I have a lib, but how to load it ?

    OMG. Whatever happened to: Get library, including header files, locate header file in filesystem at the 'right place'(tm), insert header file in source at the, 'right place'(tm), compile library, and then do the time honored $cc $myprogram -o progname $libname. ???? Sorry for the flame but...

    seg fault on fread()

    There are benefits to the OO or 'highlevel', opaque and "YOU don't need to know", maybe/possibly garbage collected model, with functionality added in everywhere. Coding in C is going to hurt coming from there. sizeof() doesn't even do what you might expect in most cases. I really love C and...
