> Does it take long to resolve the address to ip or is > the page loading slow? > Maybe you can try connecting to sites with their ip address Good idea, but comparing page loading times won't tell you much if the page contains e.g. <img src="http://example.com/huge.jpg"> Then DNS still comes into play. Better I think to compare downloading one large compressed binary with an application that doesn't do caching: curl -O http://130.239.18.142/pub/gimp/gimp/v2.2/gimp-2.2.3.tar.bz2 __________________________________ Do you Yahoo!?

Linux still surfs slower than Windows
by Chris Carlen 19 Feb '05

19 Feb '05

Hi: I have two Suse 9.1 Linuxes and one Win2k on a LAN behind a Linksys WRT54G router connected to SBC/Yahoo DSL. The router gets a dynamic IP via DHCP, and connects via PPPoE. It also receives DNS server addresses. The LAN hosts have static IPs on subnet 192.168.1.0 and statically configured DNS server addresses set to the values shown by the router. These DNS addresses are always the same: 63.203.35.55 and 206.13.28.12 . The Windows host also has a static IP and manually configured DNS servers. Also, there is a Win2k VMware machine on each Linux box with bridged networking and static IP and DNS configurations. So a total of two Linux boxes, one real Win2k, and two virtual Win2k. The problem is simply that the Linux boxes using Mozilla or Konqueror web browsers, surf the web ridiculously slow. Typically 45 seconds to load a page like www.cnn.com, and 10-15 seconds to load simpler pages like www.google.com. The Win2k, both the real and virtual machines, all surf at instantaneous speed using either Mozilla or IE. I changed the Linux DNS server configurations to free servers: 205.166.226.38 and 69.67.108.10, which improved speed significantly. Now Linux surfs about 3-4 times slower than Windows on average for all web sites. A big improvement, but still unacceptable. Typical 6-8 second loads for www.cnn.com, vs. 2-3 seconds for Windows. I posted before "Terrible Web Surfing Speed" and will summarize the results of the suggestions and other attempts at fixing this: 1. The only suggestion which improved matters was to use in the file /etc/resolv.conf: options timeout:1 This improved the surfing speed using SBC/Yahoo DNS servers to about the same speed as using the free servers, still about 3-4 times slower than Win2k. This is the condition I am in at this time. 2. Switching to DHCP IP and DNS assignments for the LAN clients did not help. 3. Turning off IPv6 did not help. 4. Captain Dondo suggested: "Well, perhaps your router/ISP is issuing ICMP redirects and your linux box ain't set up to accept them? I don't know if Windows accepts redirects by default; it makes it easier for the user but opens up security holes.... Hmmm. Which way would Windows lean? As root, run this command: for f in /proc/sys/net/ipv4/conf/*/accept_redirects; do echo 1 > $f; done Well I have all these already set to 1 so that can't be the problem: > for f in /proc/sys/net/ipv4/conf/*/accept_redirects; do cat $f; done 1 1 1 1 1 5. Use the WRT54G as the DNS server. I tried this, and it works. Some performance is a little bit better than either the free servers or the options timeout:1, but still about 2 times slower than Windows. Hmm. Very close, but still disappointingly slower than Windows. It seems with the router as DNS, that initial loads of new pages are slow, but then loading again is very fast. Before, it was the same slow speed all the time. But Windows still manages twice the initial load speed for all pages. Any further suggestions how to improve things would be appreciated. Good day! -- _____________________ Christopher R. Carlen crobc(a)sbcglobal.net SuSE 9.1 Linux 2.6.5

Mounting,Unmounting USB devices
by Dennis J. Tuchler 19 Feb '05

19 Feb '05

I have a Dell laptop attached to a monitor, printer, etc, by a port replicator. The docking device has a USB port in its side, making mounting and unmounting USB devices quite easy. My problem has to do with changing USB devices at the same USB port. How do I do it, without rebooting. Here's the story from which this question came up: I plugged a USB device into the USB port, and after several tries, the device registered at the appropriate directory, but seemed empty. I tried another USB device and tried to read that and found nothing (there is a great deal of stuff on that device). As root, I unmounted the device, and then plugged the other one in. Nothing. I saw what looked like an entry for that device at the /media directory, but ls revealed nothing. After rebooting the computer and then plugging in the second USB device, I finally found the files on it and could work with one of them. Is there an easier way? dj tuchler

Re: [SLE] Dual-booting...or trying, heh
by John B 19 Feb '05

19 Feb '05

Hi all, Wow! I really opened a can of worms! LOL. I really appreciate all the help and suggestions. I think what I'll do is go into YaST and see if I can switch my bootloader from LILO to Grub and see what happens. It seems from all the replies that this will be the best/easiest way to be able to dual-boot. I'll make sure I let everyone know how it went. Again, thanks to you all for all the help with this. Makes me proud to be a SuSE user (even if I am trying to dual-boot just for games, heh). In case anyone is wondering why I want to dual-boot, since I haven't had an M$ OS on my system in 4 years, it's because on a fixed income it's kinda hard for me to afford TransGamer at the moment, and WINE doesn't work with the 3 games I like. It doesn't make me think any less of Linux though, so no worries there. John

9.2 scsi install: no fstab found
by Jim Osborn 19 Feb '05

19 Feb '05

The Yast installer seems able to detect my hardware, and load the applicable modules, in particular the sym53c8xx SCSI driver for my adapter. All my disk partitions from my two disks are listed, but their types are all called "unknown". Selecting my root partition, sda7, manually doesn't help. Console 4 has lots of errors about SCSI parity, bus resets, etc., as though the driver is mishandling the adapter somehow. There are lots of other interesting (maybe) messages on some of the other consoles, but I can't think of any way to capture them. FWIW, when I first booted from the 9.2 CD #1, a box popped up asking me to insert modules disk 2, to which I clicked "back" in lieu of hitting the reset button (not having made a modules disk 2). The installation seemed to proceed from there, to the point where it could tell me the things mentioned above. When I finally told the graphical installer to abort, it put me back into linuxrc, so I checked what modules it had loaded. The sym53c8xx module was there, as well as several other SCSI modules. I removed the SCSI CD module, since my CD is EIDE, and things like Reiserfs and ext3 which I don't use. There remained a "mid-level SCSI" and a "disk driver" module, which I assume are needed by the sym53c8xx driver, but I'm not sure. Does anyone have any suggestions what to try next? Does this SCSI driver need some parameters in the 2.6 kernel? If so, how would I give them to the installer? I assume I don't really need to make a fleet of floppies to do the install, since I can boot from the CD drive, and in the thrashing I did, I seemed to get a list of installed modules. Many TIA, Jim

installing suse with 64 mb
by blabla 19 Feb '05

19 Feb '05

Hi there, I've got an old toshiba satellite laptop and want to put suse 9.2 fluxbox, abiword and other smallish apps on it. However, before I can get to install I am told that the system does not have enough memory to run yast and needs a swap. Since 64 mb is not enough to run knoppix or mephis I am unsure how to proceed (that is get the swap set up). I tried gentoo for a laugh but stumbled straight away at fdisk /dev/hda (unable to seek on /dev/hda). Can I still try Suse or should I go for another distro? if so, any recommendations? Thanks in advance Ingo

Firefox install on suse 8.2
by Jim Flanagan 19 Feb '05

19 Feb '05

Evening all, What is the best/recommended method for installing firefox on suse 8.2? I'm running KDE. I find no 8.2 rpm's on the suse ftp site. There is a firefox src rpm there. What I've done in the past is install the firefox script from mozilla.org, but I've only done that for a particular user. I would rather install firefox for all users on this machine. Is it best to install the suse firefox src rpm, or to install the firefox script? If the latter, which directory is recommended for all users to share the install? Many thanks, Jim Flanagan linuxjim<at>jjfiii.com

SuSE9.2 Amarok crash/segfault
by Jon Jeffels 19 Feb '05

19 Feb '05

Good afternoon all! I am having a problem with amarok crashing on a SuSE 9.2 system when I close it. It only seems to happen after I have played a file, and doesn't happen if I just open it and close it. Normally I use strace with -f to help me to solve such problems (usually a missing library or somesuch thing) but this one has me stumped. It seems to segfault, but I can't seem to "decode" what is going wrong here. Below I have included some of the output of strace. Does anyone have any thoughts as to where I can look? > amarok --version Qt: 3.3.3 KDE: 3.3.0 amaroK: 1.0-CVS > Segment of strace -f log 19694 shutdown(5, 2 /* send and receive */) = 0 19694 close(5) = 0 19694 write(7, "\1\v\1\0\1\0\0\0\0\0\0\0\340\222(\10", 16) = 16 19694 close(7) = 0 19694 close(8) = 0 19694 close(9) = 0 19694 munmap(0x4231b000, 446152) = 0 19694 close(14) = 0 19694 close(14) = -1 EBADF (Bad file descriptor) 19694 close(39) = 0 19694 close(38) = 0 19694 close(38) = -1 EBADF (Bad file descriptor) 19694 --- SIGSEGV (Segmentation fault) @ 0 (0) --- 19694 rt_sigaction(SIGALRM, {SIG_DFL}, {SIG_DFL}, 8) = 0 19694 alarm(3) = 0 19694 getrlimit(RLIMIT_NOFILE, {rlim_cur=1024, rlim_max=1024}) = 0 19694 close(3) = 0 19694 close(4) = 0 19694 close(5) = -1 EBADF (Bad file descriptor) 19694 close(6) = 0 19694 close(7) = -1 EBADF (Bad file descriptor) 19694 close(8) = -1 EBADF (Bad file descriptor) 19694 close(9) = -1 EBADF (Bad file descriptor) [....] This part goes on for quite some time in a similar vein. Any help would be appreciated, Cheers, Jon

cups printer prints only one page
by Wybo Dekker 19 Feb '05

19 Feb '05

Hi, My Laserjet-5mp, installed with Cups in SuSE-9.2, persists in printing only one page of multipage documents. When I cat a multipage ps file straight to /dev/lp0 it prints without problems, but when I send it with lpr only the first page is printed. Is there a known problem with cups filtering? -- Wybo
