Problem with script execution from a DHCP event
Post 302588158 by bypper on Saturday 7th of January 2012 05:03:12 AM

Chrooted installation
Yes, the installation is chrooted:
And I thought this, too
But I moved the script "dhcp-event" (and anothers) a the chrooted path (/var/lib/dhcp), and I have created a "bin" directory in this path (/var/lib/dhcp/bin) with a script "dhcp-event" inside, but without effect.
The problem seems point to some bug with the "execute" sentence, because the others sentences from dhcp events (set VARIABLE, other log (concat(xxx)) run OK. If I delete the sentence "execute", no errors.
The only error that is received corresponds to "execute" sentence, and always is the same:
The message is clear: is not found, but why, is not found in /usr/local/bin (located in $PATH environment), not found in /tmp, not found in /var/lib/dhcp/bin (chrooted path) ...

digest
digest(1) User Commands digest(1) NAME
digest - calculate a message digest SYNOPSIS
/usr/bin/digest -l | [-v] -a algorithm [file...] DESCRIPTION
The digest utility calculates the message digest of the given file(s) or stdin using the algorithm specified. If more than one file is given, each line of output is the digest of a single file. OPTIONS
The following options are supported: -a algorithm Specifies the name of the algorithm to use during the encryption or decryption process. See USAGE, Algorithms, for details. -l Displays list of algorithms available on the system. This list can change depending on the configuration of the crypto- graphic framework. -v Verbose output. Includes the algorithm name and filename in the output. USAGE
Algorithms These algorithms are provided by the Cryptographic Framework. Each algorithm supported by the command is an alias of the PKCS #11 mechanism for easier access. For example, sha1 is an alias to CKM_SHA_1. These aliases are used with the -a option and are case-sensitive. EXAMPLES
Example 1: Simulating output of the common md5sum program example$ digest -v -a md5 /usr/bin/vi md5 (/usr/bin/vi) = e4e3588c5212903847c66d36b1a828a5 Example 2: Digesting a file To generate the sha1 digest of the file /etc/motd: example$ digest -a sha1 /etc/motd 9498a4f5303d056ad3ecae826b59f41448d63790 Example 3: Generating a directory manifest with sha1 example$ digest -v -a sha1 /usr/lib/inet/* sha1 (/usr/lib/inet/certdb) = f6d43e6e395d50db24d34e4af4828598c8918b16 sha1 (/usr/lib/inet/certlocal) = 7f74ba4a019b809c7023212b4bda10d9485e071d sha1 (/usr/lib/inet/certrldb) = 1f845d30b8d02066647de04311e74549049852ed sha1 (/usr/lib/inet/dhcp) = e3db5e4ff40a69d13f2497254526c2015d2c37b3 sha1 (/usr/lib/inet/dsvclockd) = b61aad7ed6a0f82145c3c26aedc613ab4a1f032e sha1 (/usr/lib/inet/in.dhcpd) = 382210180c826fbb2e747236c489062bac8cc30b sha1 (/usr/lib/inet/in.iked) = be6061fad725d37256e773dc85f8bd5248649463 sha1 (/usr/lib/inet/in.mpathd) = 5bd6bf0340fd5c4cc0c53f2df158302a0e85f9d0 sha1 (/usr/lib/inet/in.ndpd) = fdb768aebe7e5eb4465e1c1bb5e679b496f5c5c6 sha1 (/usr/lib/inet/in.ripngd) = 4f56a0df2d4a252f581a73c2e84143b920d0b66b sha1 (/usr/lib/inet/mipagent) = 3c45e95231959d738625b9fcb84735148393ce47 sha1 (/usr/lib/inet/ncaconfd) = 7219542b5585a8d1104d7ce4a2ced07d8a260ea3 sha1 (/usr/lib/inet/ppp) = c96ee458549871a6ffdf2674a888b01d0c9e9740 sha1 (/usr/lib/inet/pppoec) = 5f022498d79dacacd947cddadc64f171822e3dee sha1 (/usr/lib/inet/pppoed) = 252bd2f0863dbc1b05fffae72821a2a95609b8ad sha1 (/usr/lib/inet/slpd) = dfa24cc0f0b05f790546d4f0948a9094f7089027 sha1 (/usr/lib/inet/wanboot) = a8b8c51c389c774d0be2ae43cb85d1b1439484ae sha1 (/usr/lib/inet/xntpd) = 5b4aff102372cea801e7d08acde9655fec81f07c Example 4: Displaying list of available algorithms to digest example$ digest -l sha1 md5 EXIT STATUS
