Software :: Redirecting APT Cache - Can Redirect Cache Of Apt To A Specified Folder Either On Command Line Or Via A Config Setting?
Jan 5, 2011I was laughing about klackenfus's post with the ancient RH install, and then work has me dig up an old server that has been out of use for some time. It has some proprietary binaries installed that intentionally tries to hide files to prevent copying (and we are no longer paying for support or have install binaries), so a clean install is not preferable.
Basically it has been out of commission for so long, that the apt-get upgrade DL is larger than the /var partition (apt caches to /var/cache/apt/archives).
I can upgrade the bigger packages manually until I get under the threshold, but then I learn nothing new. So I'm curious if I can redirect the cache of apt to a specified folder either on the command line or via a config setting?
General :: Apt-cache Search <package> Show Package Size?
Apr 5, 2011Is there anyway to show package size that comes up in the search so you don't have to apt-get install package individually and wait for the installation initiation and then reject to install after it gives u the [y/N] confirmation thing?

View 1 Replies View RelatedHardware :: Lshw: L2 Cache Size Vs Capacity
May 22, 2010I just bought a laptop with a T4400. Looking through lshw output turned up the following for the L2 cache:
Code:
*-cache:1
description: L2 cache
physical id: 6
slot: L2 Cache
size: 1MiB
capacity: 4MiB
capabilities: burst internal write-back unified
I'm curious as to why the size (1Mib) and capacity (4MiB) are different. Surely it can't be possible to stick something on the CPU to increase the L2 cache size, right?? So what does this mean?
I'm running 64-bit Linux Mint (derivative of Ubuntu). The kernel config says CONFIG_X86_L1_CACHE_BYTES=64 but I found nothing about the L2 cache.
Can I somehow unlock more cache to get a 4MiB L2 cache for free?
Networking :: Local Dns Server Cache Size Optimization
Apr 24, 2011Does anybody have some thoughts about a local dns server cache size? What is the optimal one? In terms of memory consumption and number of re-enters into the cache. Lets say that default size is 150, so I've change this to 500 and after some time I see 379 re-enters into the cache. Simply put I need to increase the cache size 2 times. But due to the fact that browser preloads dns names it is not possible to interpret the number of overwrites in terms that it is not possible to say if useful cache entries were overwritten or those that the browser precached ( in other words not needed ). In this case it is ok to overwrite unwanted entries because it is not likely that I'll need these entries anyway
I'm running the dnsmasq on an embedded system with limited ram and with an umts dongle attached. It is important to keep the cache size as small as possible to reduce memory usage and at the same time to reduce number of external lookups because dns latency of the umts connection is high (1-2sec for the dns query)

General :: Bash Command History Update Before Execution Of Command
Jun 7, 2010Bash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT.However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again).
I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm?

View 6 Replies View RelatedGeneral :: Evaluate Size Of Output Command?
Nov 18, 2010I'm trying to do something like this:
Code:
#!/bin/bash
cmd1=$(cat /var/log/messages | grep -e 'blocked for more than 120 seconds' | cut -c 55-62)
if $cmd1 != 0; then echo 'okay'; fi
however i'm messing up somewhere... bash attempts to evaluate the elements in cmd1. when I try to run this script it complains saying:
Quote:
test1.sh: line 5: blocked: command not found
I am open to alternatives. My intent is to replace cat /var/log/messages with dmesg, so I can attempt to determine if a problematic application I use encounters a blocked state (unresponsive for more than 120 seconds).
Should I be using a different test condition? I tried something like:
Code:
# this declares cmd1 as an array
cmd1=($(cat /var/log/messages | grep -e 'blocked for more than 120 seconds' | cut -c 55-62))
#attempt to determine if number of elements in array is greater than zero
if ${#cmd1[@]} > 0; then echo okay; fi
But I get the same error... what am I doing wrong?

General :: 512KB Maximum Transfer Size Per Command?
Apr 7, 2011I'm using fc14 and the SG driver to test some SCSI (SAS) targets. In doing so, I'm bumping up against what appears to be a 512KB maximum transfer size per command. Transfers up to 4MB sometimes work, but often they result in ENOMEM or EINVAL returned from the write() function in the SG driver. I could not find any good documentation on how the SCSI system in Linux works so I've been studying the source for drivers in drivers/scsi.
I see that there is a scsi_device struct that contains a request_queue struct that contains a queue_limits struct that contains an element called max_sectors. The SG driver seems to use this to limit the size of the reserve buffer it is willing to create. I see that there are several constants used to initialize max_sectors to 1024 which would result in the 512KB limit I see (with targets having 512 byte sectors). At this point I have several questions:
1) When the open() function for the sg driver gets called, who initializes the scsi_device struct with the default values?
2) Can I merely change the limits struct to arbitrary values after initialization and cause the SG ioctls to set the reserve buffer to allow greater values?......

Mar 10, 2011I have following BASH script?
Code:
i=0
while [ $i -lt $ARRAYLEN ]; do
if ["$META1" = "$array"];
then
META1FLAG=1
else
META1FLAG=0
fi
let i++
done
While $array contains a word like "start"
When I run the script, In the terminal I either get the response:
myscript.sh: line 3: [: missing ']'
or if $META1 contains the same word "start, I get:
myscrit.sh: line 3: [start: command not found
The purpose of the script is to evaluate a parameter that a user might include when they invoke my script, and compare it to some data that $META1 might contain. If they match I want to set a flag and later launch Xine. If they do not match, I want to set a flag to zero and do something else. I'm a bit lost as to what the responses are trying to tell me in the terminal window when I run this script.
