Looks like checking the checksums is the way to go for the PS2 games,
somehow I just assumed it wouldn't be that simple.

I thought that dvdisaster should work for DVDs based on the name, but it
gives the error "this software does not support DVD-ROM type media" for
DVD games and also for regular movie DVDs. Maybe the ebuild is limited
to just CDs for some reason.

[gentoo-user] RAM checks for chromium

[Mick]

Two Intel systems with 4G RAM failed to build chromium, even after setting 
MAKEOPTS="-j2". The ebuild is checking for a minimum of 3G RAM:

>>> Running pre-merge checks for www-client/chromium-70.0.3538.110
 * Checking for at least 3 GiB RAM ...[ ok ]
 * Checking for at least 5 GiB disk space at "/var/tmp/portage/www-client/
chromium-70.0.3538.110/temp" ...  [ ok ]

Given I've spent more than two days compiling to get nowhere with this, I'm 
thinking:

a) Chromium probably needs more than 3G now.
b) Either the ebuild, or portage, ought to check available RAM and dynamically 
adjust the number of jobs accordingly - or have I watched too many AI movies?

I see where I missed changing the Subject from an old message: embarrassing on 
me.

Being on the same local network, the other machine would have an intranet IP 
address of 192.168.0.x, where x would be a number >= 2.

I have mounted file systems by NFS but have never accessed an X server by ssh.  
I don't think I ever used ssh command directly.

The lasers in older game consoles are very weak and they get even worst with 
age. They don't tend to do well with many scratches. The disc may read in a PC 
with scratches, but then fail to load in the console. I have found PC drives to 
be far more resilient to scratches compared to consoles.

In the case of PlayStation 1, in the interest of space, they went with mode 2 
XA format which makes the discs lack error correction codes. This means if the 
disc fails in a PC it definitely will fail in the console with no way to 
correct.

I have not installed dvdisaster, but I'd be really surprised if it
won't check dvd's.  The ebuild description is "Tool for creating error
correction data (ecc) for optical media (DVD, CD, BD)" so if it really
balks at a dvd, I'd file a bug.

Also - what is your criteria for finding an error?  Could you just read
the entire disk or copy to /dev/null and just look for any read
errors?  (I'm not sure if I'd try cp or dd or some variant on dd.)

Jack


Not so much just for verification, but I'd also check out ddrescue. If the 
tool dumps your media easily, it's probably good. If it struggles, you may 
at least still have a workable image by the time it is done.


IIRC, some game discs may also throw a curve-ball here: they had 
intentional errors introduced near the end of the disc to prevent image 
dumping for copy protection. I'm sure I ran across a ps2 game or two like this.

Hi,

I found the manufacturer website.  It says this card supports Hot Plug
and Hot Swap.  Have you ever did this?  If so, any problems?  I don't
know why but outside of USB, that sort of thing makes me nervous.  I'm
old school I guess.  Plugging things into a computer was always done
when the puter was off. 

Just curious.  Oh, I did order a card.  Now to figure out the situation
on a hard drive.  :/

So as usual, they are not very Linux friendly.  Figures.  I was hoping
that there might be something helpful out there.  Sounds like there is
but only in certain cases.  That said, if that will help the OP with
only half the games, that is half that can be tested.  Otherwise, one
has to play a lot of games and see if it crashes.  ;-)

My favorite game, if you call this that, Kpatience.  I play spider
solitaire with it.  Sometimes a few other games.  I did play Tux Racer
once years ago tho.  I don't recall ever buying a game tho.  I've heard
of a lot of them and even seen some run but never was to into it. 

Maybe some of this will lead to something that can help the OP.

Not sure but I do have a rule with using --ctstate ESTABLISHED,RELATED
like yours. I even got rid of the interface argument in case that's a
problem. The box is a router and has 2 NICs going, one for WAN and one
for LAN. enp1s0f0 being the internet, and enp1s0f1 is for 192.168.1.0/24

When I'm connected to the VPN and I'm definitely not on my network, I
can do things like `ssh 192.168.1.xxx` and it works. And HTTP works too.
It's only port 53 that I am having trouble with.

dnsmasq (listening only on enp1s0f1, 192 address) gets the request from
the tun0 interface, which seems to route correctly to the 192 address.
The response that dnsmasq creates (presumably) does not route back to
the originating IP.

Happy to provide any other configuration details and packet dumps if it
helps.

Checksums do exist. The Redump project is trying to collect all relevant
disc information for every video game ever made, basically.

http://redump.org/disc/57802/

The process to generate this information is very specific and requires
software that isn't made for Linux unfortunately. But the MD5, CRC32,
SHA1 is there which can be usually be checked with `dd /dev/sr0 |
sha1sum` for a basic disc.

PS1 and PS2 games can be checked without special hardware in this case,
but for others, specific hardware is required.

In my case I have a JTAG Xbox 360, so the best way for me to check a
game is to have my Xbox 360 dump the disc contents entirely with an app
that would not be available on a normal Xbox 360. If this fails at any
point it's a bad disc (or it needs cleaning/repair).

I was wondering if the checksums could be checked?  If the OP can find
the checksum for the DVD as it comes from the factory, then he could
check what he has against that.  Question is, is that info even
available or does it vary over batches of DVDs?  If it varies, it may
not be possible to test that way even if checksums are available. 

Thing that makes this different for the OP, a damaged audio or even a
video DVD can be corrected sometimes within the player itself.  I know
audio can and has done so for ages.  Video maybe, maybe not.  I suspect
video game DVDs fall more into the category of a data disk tho.  A
scratch may not be a problem with audio but when it comes to data, it
could be broken completely. 

Another thought, maybe if one is bad the maker would replace for a small
fee?? 

Just throwing that out there in case checksums are available and it
could be done that way.  Sort of doubt it tho.

I just did eix and indeed qttest 5.11.1 is amd64 (not ~amd64).
I upgraded it and now emerge @preserved-rebuild succeeds.

I did not resync, just emerging qttest did the trick.

Thank you.

Is that only forwarding packets for new (i.e. not existing) connections?

Ours looks like,

iptables -A FORWARD -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
iptables -A FORWARD -s $INSIDE_NET-j ACCEPT
iptables -A FORWARD -i $VPN_INTERFACE -j ACCEPT

(and you need to enable the net.ipv4.ip_forward sysctl)

[gentoo-user] Routing issue with OpenVPN and internal DNS

[Andrew Udvare]

Very confused here, but I feel like I'm missing a route on either the client 
side or the server side. Or it is a firewall rule but that doesn't seem likely.

My OpenVPN server/client config is almost identical to that on the wiki page: 
https://wiki.gentoo.org/wiki/OpenVPN#Configuration

After connecting from another ISP and then connecting to the VPN, I use dig to 
query the internal server:

dig @192.168.1.254 pi.hole

The server can see the DNS request from the client:

 # tcpdump -i tun0 'port 53'
dropped privs to tcpdump
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on tun0, link-type RAW (Raw IP), capture size 262144 bytes
02:21:07.996606 IP 10.100.0.6.50312 > 192.168.1.254.domain: 13933+ [1au] A? 
pi.hole. (36)

Even the dnsmasq log is showing the request:

Dec  3 10:21:45 dnsmasq[1026]: 4744 71.214.144.51/49349 query[A] pi.hole from 
71.214.144.51
^ shows the external IP. Is this normal?

On the client side, dig times out.

So if it can come through client-to-server but won't go back server-to-client, 
where could the issue be?

I even changed the iptables policies for INPUT and FORWARD to allow to see if 
anything would change but the result was the same.

I have HTTP running on the server and accessing via the IP works fine:

 $ curl https://192.168.1.254 -k

Just a wild guess, the utils were previously installed with glib but are
now a separate package.

I've just noticed this:

[N] x11-wm/xpra ((~)2.2.6-r1): X Persistent Remote Apps (xpra) and 
Partitioning WM (parti) based on wimpiggy

I haven't looked into it, but it may perhaps offer something useful.

I use icewm 1.3.8, now feel stuck in a rut because I want to also try jwm, 
ratpoison and i3, and upgrade where possible to icewm 1.4.x .

I see also the suggestion 

 $ ssh -Y 

but what would be the syntax for specifying  where  is a 
different computer on the same local network?
