Python on Solaris: Wrong ELF class: ELFCLASS64

If “pip” installed 64-bit libraries, while python is a 32-bit binary, “pkg” might stop working with the following error messages:

ImportError: ld.so.1: bootadm: fatal: /usr/lib/python2.7/site-packages/lxml/etree.so: wrong ELF class: ELFCLASS64
ImportError: ld.so.1: python2.7: fatal: /usr/lib/python2.7/site-packages/_cffi_backend.so: wrong ELF class: ELFCLASS64
$ file `which python`
/usr/bin/python:	ELF 32-bit LSB executable 80386 Version 1 [SSE], dynamically linked, not stripped

The workaround is to remove the corresponding python packages (in this case cffi and lxml), download and recompile them manually with “-m32”:

$ export CFLAGS="-m32"

One-liner: how to generate group-url for all remote-access tunnel-groups (Cisco ASA)

This one-liner takes Cisco ASA config, checks for “tunnel-group … remote-access” and generates the following two lines:

tunnel-group GROUPNAME webvpn-attributes
 group-url https://CISCO_ASA_FW_FQDN/GROUPNAME enable
for i in `fgrep tunnel-group CISCO_ASA.conf | fgrep remote-access | awk '{print $2}'`
do
echo "tunnel-group $i webvpn-attributes"
echo " group-url https://CISCO_ASA_FW_FQDN/$i enable"
done

How to install and keep an obsolete Solaris package

If you (like me) are still using Solaris (why BTW, if I may ask?), then you might stumble upon the problem of disappearing packages. Let’s take, for example, gimp:

# pkg list -af gimp
NAME (PUBLISHER)          VERSION                    IFO
image/editor/gimp         2.6.10-5.12.0.0.0.97.0     --o
image/editor/gimp         2.6.10-0.175.3.0.0.26.0    ---
image/editor/gimp         2.6.10-0.175.2.0.0.27.0    ---
image/editor/gimp         2.6.10-0.175.1.0.0.24.0    ---
image/editor/gimp         2.6.10-0.175.0.0.0.2.0     ---
image/editor/gimp         0.5.11-0.151.0.1           ---

Flag “o” means “obsolete”. If you have version “2.6.10-0.175.3.0.0.26.0” installed, and it gets updated to “2.6.10-5.12.0.0.0.97.0” (which is obsolete), your package will get removed. If this what happened, here’s the path to restore it.

First, install the latest version before “o”:

pkg install -v image/editor/gimp@2.6.10-0.175.3.0.0.26.0

Then “freeze” it:

# pkg freeze image/editor/gimp

Now if you run pkg list again, you will see two new flags:
“i” – installed
“f” – frozen

# pkg list -af gimp
NAME (PUBLISHER)            VERSION                    IFO
image/editor/gimp           2.6.10-5.12.0.0.0.97.0     --o
image/editor/gimp           2.6.10-0.175.3.0.0.26.0    if-
image/editor/gimp           2.6.10-0.175.2.0.0.27.0    ---
image/editor/gimp           2.6.10-0.175.1.0.0.24.0    ---
image/editor/gimp           2.6.10-0.175.0.0.0.2.0     ---
image/editor/gimp           0.5.11-0.151.0.1           ---

# pkg freeze
NAME               VERSION            DATE            COMMENT
image/editor/gimp  2.6.10-0.175.3.0.0.26.0:20150705T202845Z 15 Feb 2017 23:01:02 CET None

One-liner: how to count the total amount of specific lines in several files

Let’s calculate the amount of lines, containing the word “extended” in */*.conf files:

egrep -c extended */*.conf | 
awk 'BEGIN {FS=":"; sum=0;}{sum +=$2} END {print sum}'  

BTW, using awk alone is slower:

time awk 'BEGIN {sum=0;}/extended/{sum++} END {print sum}' */*.conf
110653

real	0m0.94s
user	0m0.91s
sys	0m0.01s

time egrep -c extended */*.conf | 
awk 'BEGIN {FS=":"; sum=0;}{sum +=$2} END {print sum}'
110653

real	0m0.13s
user	0m0.10s
sys	0m0.02s

fgrep is slower than egrep:

time fgrep -c extended */*.conf | 
awk 'BEGIN {FS=":"; sum=0;}{sum +=$2} END {print sum}'
110653

real	0m0.21s
user	0m0.17s
sys	0m0.03s

Firefox 18.0 crashes on Solaris

Update: fixed in v19.0beta (at least v19.0b1 build3 looks good):
ftp://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/ (19b1 does not save sessions, though πŸ˜‰

Firefox 18 (all betas and 18.0) crashes on Solaris 11 and OpenSolaris. The workaround is to set the following variables to “false”:

browser.cache.disk.enable
browser.cache.memory.enable
browser.cache.disk_cache_ssl

See bug 827971.
