| 00:56 | <fjavier> | hi all |
| 00:56 | <fjavier> | i have a bit problem, i am configuring snort inside an uml machine, but don't lets me to listen to eth0, et0:W191 or venet0 |
| 00:56 | <fjavier> | how can i do it work ? |

| 01:34 | <fo0bar> | fjavier: I believe you need CONFIG_NETFILTER enabled |
| 01:35 | <fjavier> | mmm i have no access to netfilter :( i am inside an vds provider, i rent an root account |
| 01:35 | <fjavier> | some said me here at irc, that i have to have access to tun/tap too :( |
| 01:39 | <fo0bar> | err sorry, you need CONFIG_PACKET enabled in the kernel to use things like tcpdump and snort, I can't think of anything within the UML instance that would change that |
| 01:39 | <fo0bar> | does tcpdump work? |
| 01:44 | <fjavier> | no :( |
| 01:45 | <fjavier> | i would like to say the system admin to enable it, because it's important. Are there security problems ? |
| 01:46 | <fjavier> | mm the admin says, that is not uml, it is Linux-Vserver |

| 07:08 | <qaps> | hello |
| 07:08 | <qaps> | when in an uml-guest I do ifconfig eth0 192.168.0.231 netmask 255.255.255.0 up |
| 07:08 | <qaps> | it doesn't complain |
| 07:09 | <qaps> | but when i do a 'ifconfig' after this, i get no response |
| 07:09 | <qaps> | so the network is not setup |
| 07:10 | <qaps> | i have chmodded /dev/net/tun etc |
| 07:10 | <qaps> | on the host |
| 07:10 | <qaps> | and i am out of idea's where to look further |
| 07:11 | <qaps> | anybody an idea where to look ? |

| 20:50 | <danderson> | hi all |
| 20:50 | <danderson> | so, is there a way to tell a UML guest kernel where to store its physical memory files? |
| 20:51 | <danderson> | I'm running into the documented "Kernel panic - not syncing: Kernel mode signal 7" problem |
| 20:51 | <danderson> | which is caused by a /tmp that has a size limit of 16M |
| 20:51 | <danderson> | I can't change that size limit, it's mounted by the vserver admin that way |
| 20:52 | <danderson> | I can however mount another ramdisk elsewhere to store those files - but how can I tell UML to use that other space? |
| 20:52 | <fo0bar> | danderson: export TMPDIR to be another directory |
| 20:53 | |-| | ElectricElf [~dbharris@electricelf.noc.oftc.net] has quit [Ping timeout: 480 seconds] |
| 20:53 | <danderson> | okay; and this other directory had better be a ramdisk or similar FS, right? |
| 20:54 | <fo0bar> | doesn't have to be, (would you replace your computer's memory with 100% swap? ;), but yeah |
| 20:54 | <danderson> | hrm |
| 20:54 | <danderson> | this sucks |
| 20:54 | <danderson> | this vserver really sucks |
| 20:54 | <danderson> | /tmp is throttled to 16M, and I don't have the permissions to mount anything else in my vserver domain |
| 20:55 | <danderson> | okay, is there another hack I can use to get my UML into memory? :-) |
| 20:55 | <danderson> | because barring that, I will be running on 100% swap, which sucks royally |
| 20:58 | <danderson> | also, unsurprisingly, booting of a hard drive pushes the host load through the roof. |
| 21:34 | <danderson> | bah, I give up. |
| 21:34 | <danderson> | Just so y'all know, vserver is the death of UML |
| 21:35 | <danderson> | it is so ridiculously restricted that I can't decently boot a uml kernel inside one |
| 21:35 | <danderson> | /tmp has a stupid size limit, tun/tap is forbidden because it can break the segregation between vserver domains, ... |
| 21:36 | <danderson> | so, you have to boot a machine on non-tmpfs disk (ie. "100% swap machine"), and network with slirp |
| 21:36 | <danderson> | ugh. |
