greets, is running ntp recommended on the vps? or does the host take care of that? Run your own NTP. will do bharatak: i use these good west coast servers in my ntp config: http://pastebin.ca/1973687 i'm just using the pool, shouldnt that magically figure out good servers? it should be good enough... but won't find servers that are close by... probably doesn't matter much though do you have any issues with stuff being screened ? cpet, you mean a firewall before your vps? seems open to me cpet: the only firewall settings infront of a vps is rate limiting ssh connections to your vps; most people don't notice, but attackers do do you rate limit SYN packets or everything? It's not size, it's number of times. aha. makes sense re: ntp. I just use the pool. I don't need it any more accurate than that really (sure it's fun to figure out which one is the closest/best) toddf: That's already applied? So my PF rules are for nothing? :P depends on your PF rules True don't listen to him. be an asshole and only, ONLY use stratum 1 servers. bonus points if it's a restricted one and you haven't given them a heads-up. heh screen as in "screen irssi" not a firewall was supposed to be a trick question :) tmux irssi ;) tmux weechat wow. weechat looks neat I'm pretty happy with irssi though I'm prety happy with screen instead of tmux, but I am a big fan of weechat. I start new people on tmux and weechat, since those are actively developed projects. irssi isn't actively developed? is there something that tmux does that screen doesn't ? or is it just different oh, hah. the FAQ goes right into that. ah, just a different way. (generalized comment) mike-burns: Are there OTR and/or fish stuff for weechat? No idea. That's kind of important for me :P http://wiki.flashtux.org/wiki/WeeChat/irc-otr http://www.weechat.org/files/scripts/weefish.rb ohyeah. bitlbee works with it, /obviously/ mike-burns: the flip side of that is how active does screen/tmux or irc client development really need to be? irssi only has one bug that bites me, and it's relatively rare. yeah. irssi is mature now, it shouldn't constant updates. +require It should be updated to be more convenient. I get that openbsd wants tmux because it's !gnu, but the only draw for me on weechat is the sidebar. and I'm not content to give up stability for that ;) I guess. Convenient how? sidebars are for people that can't remember what channels they 're in. tooth: i would like to see you try when you are on 20 different networks lol For example, weechat updates have things like that bar showing where you stopped reading. I fully understand that my solution is a solution for me only, which is to cutdown on networks if I can't remember them. vcs: I use irssi on multiple networks. I see which server and channel I'm in, for each window. mike-burns, irssi has a trackbar. jpalmer: its hard to remember where to switch to in a timely manner clients like irssi do not scale well no, they don't vcs: /window list doesn't work for you? i've heard crazy people exist which maintain upwards of 40 channels with irssi haha im not insane irssi was great for < 10 channels but i no longer wish to subject myself to that weechat also has split screens. being on tons of networks / channels *shrug* to each his own, I guess. I use irssi for well over 10 channel. not quite 40. and have *no* problems with it. irssi isn't bad. irssi is great, i just think it does not have what it takes to scale well it can handle it. just not as gracefully this is one of the few times where i prefer GUI over cli really, not a problem for most people I actually like not having any sidebars. tooth: or want a userlist without /names haha. also, i dont miss the ocasional lag i get running it remotely xchat is nice, no bloat, and everything i want yeah. i don't that. has python, perl, and tcl split screens would be nice, although I wonder if it works as badly as screen's split screen sdo. irssi only has perl /me cringes I figure if there are more people than can be shown on the side without scrolling, than I'm not going to care anyway screen's vertical splitting sucks :/ screen sucks in general i rather use multiple logins weechat has Ruby, Python, and a few other languages I know. weechat is good vcs: to each their own. I'd rather have one local window open per remote host. jdoe: so would i until i have to break out screens highly unintuitive scrollback buffer yeah on that note, i'm glad multiple options exist. Tabbed terminals is what i like keeps it in one window but gives me the option of moving them around on the fly not at the mercy of doing man screen tooth: NO, MY WAY IS THE BEST WAY. Multiple options is perfect. anyway. the little detail that sold me on irssi, was that I was able to configure my date/time format to be different in the window than what is logged to disk. Heh. The thing that sold me on weechat was splits and things like Alt-a and Alt-u, plus Ctrl-r. this was, of course, many years ago now. does anyone have any gotchas to be aware of when reinstalling the OS on a VPS via console? getting ready to blow mine away soon. Tadaka: what OS? going to move from ubuntu to freebsd8.1 ah very good. well just follow the HandBook :) ok, that's all I was wondering. :) openbsd is the only gotcha, isn't it ? it's pretty straight forward tooth: OpenBSD has it's issues :P just wanted to be ready for any possible surprises. FreeBSD is, generally, pretty smooth going. I've done freebsd a number of times, but this will be the first install on arpnetworks ARPnetworks was basically made for FreeBSD. gotta love that I decided to give jaunty a try when I ordered my vps and regretted it almost immediately Common reaction. heh just need the iso added to my system and Ill get that nasty ubuntu system off your network. :P thanks for the confirmation folks 2141 < tooth> i've heard crazy people exist which maintain upwards of 40 channels with irssi <- I'm one of those :) mike-burns: I'm curious, how are vertical splits with wee-chat? they're super slow in screen, but I assumed that's because terminals aren't really optimized for scrolling half the screen up :/ (from near the LHC!) LHC! That's fantastic. Just down the street from me. (on a galactic scale, anyway) well - literaelly only a few miles from me right now toured it yesterday and today COOL would have gotten to go into the tube, but the experiment is live so no chace chance awww. so close. Wouldn't want a magnet quench while you're down there. RandalSchwartz: LHC is a local hockey club here :D So it's not *the* LHC heh. it's *the* LHC for most of the world I guess it depends on whether you're into sports or particle physics. Has anyone figured out how to get the jitter down on NTP? No matter what I try it's always around 20ms. jazz57: jitter: 0.011383 s On my Xen VPS jitter is less than 1ms. I'm not sure if that's b/c of Xen or the OS. ww: Is that on FreeBSD? jazz57: yes That's a little better than what I'm getting. Any special configs? I think Xen has a virtualized clock. just a hand-picked set of peers http://pastebin.ca/1973687 ww: same I'm kind of a time nut. I used to run a FreeBSD box with a GPS attached to the serial port. Worked amazingly well with just a cheap automotive unit too. i guess it wouldn't be the worst idea for arp to put up a couple of ntp servers for local use... keep the load off of the stratum 1s if anyone at arp is using stratum 1's, they should be shot. I doubt that would fix the jitter problem though. well, except for specific reasons ;) and with consent. Some servers are listed as public, go ahead and use, no notify necessary jpalmer: everything in that list is a part of the ntp.org pool and open access sure. but, unless you have a specific need for your time to be *that* dead-on, stratum 2 or stratum 3 are prefereable. leave the stratum 1's for those who actually *need* it. when i made the list, i looked for hosts that were close in terms of network topology ww: well, pool.ntp.org is a special case. if there are stratum 1's in there, great. I meant more about people specifically hunting stratum 1 peers ... didn't actually pay attention to stratum. ... they all happen to be 1 though I just set mine to us.pool. ww: Are your round trip times longer than your pings? Err, I mean jitter. but i agree in general... that's why it would be nice to have a local ntp server or two... i'd happily open up river.styx.org if there were interest cute domain name I would love to see a local GPS clock, though I think there is something limiting the precision in our setup. does charon@styx.org exist? charon.styx.org used to ww: jazz57 GPS clock is no more accurate than pool.ntp.org. the only place where GPS timing makes more sense, is when there is no internet connectivity for a remote site. on rtt, ping with ~600 byte packets are about the same as jitter well, i won't say "no more accurate" but not substantially more accurate. If it was on the local net, the delay and jitter would be much lower. When I ran my GPS server on the LAN, my other server immediately improved its performance. But there must be something about the FreeBSD/ARP setup that is introducing quite a bit of jitter. My Xen setup is an oder of magnitude more accurate for some reason. stability: 0.000 ppm I've got the same, but my best peer shows a jitter of 15 ms, whereas on Xen it's 0.056ms. Amazing. RandalSchwartz: you should go into the tube anyway. Statistically, I'm sure you'll be fine... jazz57: if you're using the ntp pool, don't worry about it. Your client will kick out useless peers. jdoe: Problem is not the peer, though. They're *all* around 15-20ms. I mean, that's not bad...I don't really *need* any more accuracy. I'm just wondering why its relatively higher. Seems more a Windows box than Unix. ;-) could be difference you see with xen is hypervisor vs. emulator/ ? ww: That what I'm thinking. I just wish someone knew what was going on. More of a curiosity than a need. I think the pll loop will stay synched up to about 128ms, so no worries. jdoe: I've noticed no speed issues with vertical splits in weechat. hmm... maybe I'll give it another shot. To clarify I mean text scrolling speed not... I dunno, general app speed :) evening cana nyone help me out on this - > znc.cpp:2069: fatal error: error writing to /tmp/ccc771ui.s: No space left on device I just make a vertical split to try iy. t There is a tiny bit of lag. But it's hard to say if it's because of the split. Oh when I un-fullscreened my window the lag disappeared. mike-burns can u give me hand? nuke-: read the error message? yes but i cant dump /tmp can i? earse/dump dxtr? Uhm, you're out of space on /tmp. You'll have to make it larger. but i never got this before, theres no way of dumping it? or erase whats there? cause its /tmp seems empty df -h Or du -hs /tmp first gives me this Filesystem Size Used Avail Use% Mounted on tmpfs 124M 0 124M 0% /lib/init/rw udev 10M 572K 9.5M 6% /dev tmpfs 124M 0 124M 0% /dev/shm overflow 1.0M 0 1.0M 0% /tmp second this du -hs /tmp err 0 /tmp Your /tmp is 1MB big mike-burns: yeah... that's what I was expecting. My understanding is it's not a screen/weechat/whatever-specific issue, the terminal has shortcuts for scrolling the entire window, just not parts of it. hello garry for you time nazzi's .. until vmt(4) or a similar driver exists for kvm guests, where the guest can sync its time with the host, and the host uses accurate ntp timing, running ntp on a kvm system is only going to get you so much accuracy .. ;-) toddf: One of the things I like with kvm is that the guests can set their own time I had another VPS on some-popular-virtualization-technology-I-don't-remember-the-name-of that didn't let me set the time And the host was so horribly out of sync it was disgusting dxtr: it is not virtualization if you don't have root and can set your time there are some sites which claim to be virtualization but infact are glorified chroot() env's toddf: It's really popular among vps companies it would be popular to run something that doesn't require resources of a true vps i.e. it's more efficient and cost effective if you want to run linux .. most of us here don't OpenVZ! That's it "It is similar to FreeBSD Jails and Solaris Zones." Bleh like I said, glorified chroot Yeah Didn't know that :P I just knew it ucks sucks* toddf: I was going to say, it's largely a moot point... if you're that sensitive to jitter you shouldn't be on a vps :P /// RandalSchwartz: what DNS server do you use? up_the_irons: you had recommended a DNS server months ago, you said it was the hottest new thing? fink: for backup, or hosting your own zone? or a recursive server? hosting (ie, what are you looking to do) ok, dns.he.net free, and solid. thanks sure btw: it'll also work as a slave, if you want to run your own DNS master. jpalmer: atm i'm using tinydns never used it. if it does BIND style zone transfers, he.net servers should be able to slave the zone.
