ive encountered quite strange phenomenon; when using client.runcommand() function, entire output switch, when using own implementation: sshclient cl = new sshclient(ip, username, password); cl.connect(); shell = cl.createshellstream("tail", 80, 24,800, 600, 1024); streamwriter wr = new streamwriter(shell); streamreader rd = new streamreader(shell); wr.autoflush = true; wr.writeline("show int status"); string rep = shell.expect("switch_wan#", new timespan(0,0,3)); messagebox.show(rep, "output"); i partial output, , prompt saying --more-- how can entire output switch? an example partial output: show int status port name status vlan duplex speed type fa0/1 team7 connected 97 a-full a-100 10/100basetx fa0/2 team7 connected 97 a-full a-100 10/100basetx fa0/3 team7 connected 97 a-full a-100 10/100basetx fa0/4 team7 connected 97 a-full a-100 10/100basetx fa0/5

is there way change mediawikis css skins without affecting printable-version-layout? to make more clear: mediawiki has own stylesheet it's "printable version"-page (print.css). don't want have changes stylesheet made in common.css appear on printable-version-page too. so, if change font-size "normal" wiki-pages, still want have original font-size on printable-version-pages. use following in css: @media print { .element-with-your-class { style } } the "@media print" ensures styles set within applied when page printed. see this link more information on media queries.

i unable understand regions in aws stack. read somewhere in aws document uploading data(s3) 1 region not reflects automatically other region. need upload available regions reflects uploaded file world wide? used upload s3 using aws console in 1 region , not aware of region upload in aws. today changed in region in aws console url , found content same. if reflects automatically point of specifying region when uploading s3 or other aws service. i understand confusion it's not clear how work. how works imo: you can choose region optimize latency, minimize costs, or address regulatory requirements. objects stored in region never leave region unless explicitly transfer them region. more information regions, see accessing bucket in amazon simple storage service developer guide. therefore when create bucket being asked choose regions bucket has got regions specific address i.e.: s3-<region>.amazonaws.com if able see same content of bucket in different regio
