The open driver might help you there. I remember it saving my rear end when I was stuck with a laptop that had some crap ati card.

Acceleration, compositing and suspend to ram worked close to flawlessly on that machine. The fact that I had to spend hours compiling mesa and the open driver made it almost worthwhile.

Still, depends very much on what card you have and what version of the driver you have available. There's also stuff like radeonhd that you could try.

Yeah, radeonHD wouldn't work on this model. . . Was just a weeee bit too old.

So I am going to start up a samba box for testing and learning, I hear it is a bit of a bumpy road, Have any of you all had experience with it?

As Bob said, as long as you're not doing AD stuff, retardedly simple. Just remember don't install samba4, samba3 is a LOT easier to work with, although I hear 4 is getting there.

There are two servers, the first has a directory containing many files, all of which I want to move to the second. I have SSH and FTP access to the first, but only FTP access to the second, otherwise I'd just use SCP.

What's the best way to get the directories and files over to the second? I had a go at connecting from the first to the second using FTP, but couldn't figure out a way to put things recursively.

FTP them to your PC and use a client like filezilla to put them back, it will create the folders etc.

ncftp can easily put recursively, use "put -R"

I generally use the lftp mirror command, the ncftp recusive mode mentioned above is similar. Or depending on how big the data is, a bigass tar file (possibly chopped into bits, using split and then cat to reconstruct it on the other end), but I guess if you don't have SSH then you won't be able to do that.

This is kind of a noob question, but I'm working on Solaris 10 without root privileges and I need to identify what pid is listening on what port. I know there's a tool called lsof, but it's not installed and I don't have the access to install it. So for example, say I want to find out what port an Apache server is listening to (without looking at the config files)?

I hate to keep going on like "that won't work, oh yeah also that won't work either" but this is really a weird scenario - I don't want to delve into all the details but basically my org's user group is sort of gimped as we don't truly "own" the server, and on top of that the security group doesn't like ANYONE except themselves running security scanners. If I could just pop into all of the config files to find these ports that'd be great, but again, I don't have read access to the install directories for all of the services.

This might be impossible with the ridiculous restrictions placed on my usergroup, but I thought I'd throw it out there to see if anyone knew a trick. This isn't for any sort of subversion or trickery or anything, just an annoying restriction making my life difficult.

Menacer: Nov 25, 2000; Failed Sega Accessory Ahoy!

I'm in the unfortunate position of needing to upgrade a handful of computers in my office to RHEL6, a process with which I am completely unfamiliar. Our IT department is neck deep in other stuff, so they gave me the DVD, an RHN activation key, and said "have at it." I installed from scratch, and once started up, opened a root terminal and used "rhnreg_ks --activationkey={our key}" to activate the RHN subscription. I'm able to get software updates, so I believe our RHN subscription is working.

That's all well and good, and I'm able to install most of the packages I need. However, I'm unable to install some fairly normal packages, as they don't appear to be in any of the installed repos that this system knows about. One big example is gcc-gfortran.

In the graphical Add/Remove Software utility, searching for 'fortran' comes up with compat-libgfortran and libgfortran, but no actual gfortran binary. 'yum list | grep fortran' from the command line returns the same.

In the GUI Add/Remove Software utility, the available software sources are "Red Hat Enterprise Linux 6Client - Source" and "Red Hat Enterprise Linux client (v. 6 64-bit for x86_64)". ("Red Hat Enterprise Linux 6.0" is also listed listed, but is unselectable). The only entries in /etc/yum.repos.d are packagekit-media.repo and rhel-source.repo (which points to ftp.redhat.com, which currently only contains SRPMs for RHEL6). 'yum repolist' returns:

code:

Loaded plugins: refresh-packagekit, rhnplugin
repo id               repo name                                                 status
rhel-source           Red Hat Enterprise Linux 6Client - Source                     0
rhel-x86_64-client-6  Red Hat Enterprise Linux Client (v. 6 for 64-bit x86_64)  3,326

Is there some kind of RHEL-specific step I'm missing to get access to packages I need? Is this behind some paywall that I'm supposed to know how to access as an RHN subscriber? Scientific Linux 6.0's main repo includes gcc-gfortran, so I'm really at a loss here as to why RHEL wouldn't have it available.

Edit: Oh my loving god. Is this because I'm using RHEL6 Client instead of RHEL6 Workstation?

Try the script I posted above.

I would but it loops through all of the pids using pfiles, and while pfiles would work fantastically if I owned all of the processes I'm concerned about, I don't - which complicates things.

Like I said, this isn't a huge deal or anything, I was just looking for a shortcut rather than digging for all of the configuration files or reaching out to the people who do own the processes. Thanks for the suggestions

I'm unable to compile Fortran applications with the installed GCC package, with an error complaining about being unable to find f951-- This is usually indicative of gfortran not existing. And, FWIW, Scientific Linux 6.0 has a separate gcc-gfortran package in their repo.

I'm stumped. Looks like you're properly registered with RHN, have the repo configured correctly and gcc-gfortran should be in the repo as it's in CentOS, Fedora and RHEL server. I guess I'd try a yum clean all and then see if it appears in yum list gcc-gfortran, and failing that try to reregster with rhn_register.

I have the sneaking suspicion that this is because the IT department gave me a Client, not Workstation, version of RHEL6 Desktop. To quote the advertising copy:

quote:

Workstations are designed for advanced Linux users. In addition to the tools provided in the Desktop variant, the Workstation variant supports a stand-alone development environment.

Since yum clean all didn't solve anything, I'll next see if I can get IT to burn a Workstation copy. Hopefully that will put this whole sordid mess behind me.

I inherited a Wyse V90L here at work. It's got a 512mb flash drive and 512 megs of ram. I'd really love to turn this thing into a low power seedbox for use at home.

I figure I'd need a 128mb swap partition so that leaves me with about 384 megs to work with on the flash drive.

All I need is basic tools, a text editor, screen, zsh, rtorrent and OpenSSH daemon. I have a 2TB usb disk I can use to download to. Samba would be nice to for XBMC to mount it, but it's not 100% necessary.

I'd try Slackware first. If you use the menu-based installer you can pick only what you need and come up with a surprisingly small, but efficient little system. Your 512Mb of RAM will hardly be challenged[*], so you could even cut back on swap space. I know the old rule is 2.5 the amount of physical mem, but in your situation it's unlikely you'll use much.

[*]Just for shits and giggles, I started every daemon on an old PII I have with 128Mb RAM; incl. Sendmail, Apache, MySQL, Samba, SSH, NFS, Tor/Privoxy. Total amount of memory used idling: 64Mb. Put some load on, still not using swap.
